Intro:

Welcome to the Construction Disruption Podcast, where we

Intro:

uncover the future of design, building, and remodeling.

Todd Miller:

I'm Todd Miller of Isaiah Industries, manufacturer

Todd Miller:

of specialty metal roofing and other building materials.

Todd Miller:

Today my co host is Ethan Young.

Todd Miller:

How are you today, Ethan?

Ethan Young:

I'm doing pretty good, Todd.

Ethan Young:

How about you?

Todd Miller:

I'm doing real well also.

Todd Miller:

So I heard an interesting statistic the other day.

Todd Miller:

Um, I heard that the average dog barks 273 times a day.

Ethan Young:

Wow.

Ethan Young:

Okay.

Todd Miller:

Of course, that is just a rough estimate.

Ethan Young:

Oh, geez.

Ethan Young:

Okay.

Todd Miller:

Okay.

Todd Miller:

I don't know if I've told that before or not.

Todd Miller:

I hope I haven't.

Todd Miller:

Anyway, it's an oldie but a goodie, so it's classified as an oldie

Todd Miller:

but a goodie if I have told it.

Todd Miller:

Well, let's go ahead and get things rolling here with this

Todd Miller:

episode of Construction Disruption.

Todd Miller:

Um, today's guest is going to talk to us about something, um, that I think

Todd Miller:

is just being talked about increasingly in the world of architecture,

Todd Miller:

engineering, and construction.

Todd Miller:

And I think sometimes it's talked about a whole lot more than it's understood.

Todd Miller:

And that is carbon capture, helping to reduce the amount of CO2 in the atmosphere

Todd Miller:

by capturing it in a non damaging way.

Todd Miller:

Increasingly, we're seeing some products out there that are said

Todd Miller:

to reduce smog and C E C O 2.

Todd Miller:

And today we're going to learn about that from our special guest, Tim Sperry.

Todd Miller:

Tim is the founder of Carbon Limit and also of Smog Armor.

Todd Miller:

Tim, welcome to the show today.

Todd Miller:

Thanks for having me on.

Todd Miller:

Great to be here.

Todd Miller:

Well, we're anxious to learn and glad to have you here today.

Todd Miller:

So, um, I think it's You're an interesting guy in that you don't really have a

Todd Miller:

degree or formal background in chemistry.

Todd Miller:

Um, yet you're on this leading edge technology.

Todd Miller:

Uh, love to hear a little bit about yourself and your background and what

Todd Miller:

brought you to where you are today.

Tim Sperry:

Sure.

Tim Sperry:

So, um, yeah, you're absolutely right.

Tim Sperry:

And I will say in preface this, yeah, half of my family are collegiate level

Tim Sperry:

educators and the other half are inventors and entrepreneurs, a majority of them

Tim Sperry:

are self taught and invented some pretty.

Tim Sperry:

incredible things, uh, from capacitors and gyroscopes and other things

Tim Sperry:

for hollow spaceship and, uh, international space station to the

Tim Sperry:

equipment that makes some classified military, uh, equipment and weaponry.

Tim Sperry:

And I will also say this, you know, I'm an entrepreneur at heart,

Tim Sperry:

although I did go to college, found the path of material science.

Tim Sperry:

And midway through, and I even took a zoology course and kind of, you know,

Tim Sperry:

went, went on the path of material science because I've always been an

Tim Sperry:

inventor and then made a U turn when I saw how effectively segregated, uh,

Tim Sperry:

you had your science and business, uh, you know, you were almost on,

Tim Sperry:

in most universities, it just seems to be there on separate sides of the

Tim Sperry:

universe and separate sides of campus.

Tim Sperry:

So I didn't really want to go and live in a lab nor create notches on the

Tim Sperry:

belt for how many publications and how many patents that I could create.

Tim Sperry:

So I took the path of Google Scholar, uh, you guys familiar with Google Scholar?

Tim Sperry:

Yeah, definitely.

Tim Sperry:

I am not.

Tim Sperry:

You're going to have to help me out.

Tim Sperry:

Yeah, most people aren't.

Tim Sperry:

Um, so if you Google Google Scholar, you don't have to just do it that

Tim Sperry:

way, but you'll get a new search box and it looks like a regular Google

Tim Sperry:

search page, uh, and it'll say Google Scholar above the search box.

Tim Sperry:

Now, every time you plug something in there for a search, it actually

Tim Sperry:

gives you all of the relative and related publications that

Tim Sperry:

have been created globally.

Tim Sperry:

Um, different scientists, different universities.

Tim Sperry:

It's a mine.

Tim Sperry:

It's, it's a gold mine of just incredible technologies, um, tests.

Tim Sperry:

Uh, different materials.

Tim Sperry:

Uh, it's really, it's really pretty awesome.

Tim Sperry:

I, I geek out on it quite a bit, but you could go down Google scholar,

Tim Sperry:

send your 10, 000 hours there and you would become an absolute master at

Tim Sperry:

whatever it is that you want to do.

Tim Sperry:

If you're studying, you know, negative emission technologies via inorganic

Tim Sperry:

materials, as I did, um, getting into negative emission technologies.

Tim Sperry:

And then to your point of carbon capture, I love to go down the path of carbon

Tim Sperry:

capture utilization and storage CC us.

Tim Sperry:

So I pretty much went that pathway to get there.

Tim Sperry:

Uh, and it's, it's been a really incredible journey.

Tim Sperry:

And I think I went down that path a little bit before it became so popular

Tim Sperry:

in the media and such a big deal.

Tim Sperry:

Uh, I just, it always been something that has been driven from my personal passion

Tim Sperry:

to want to solve air pollution as I lost family members due to Air polluted, uh,

Tim Sperry:

that's unfortunately before their times.

Tim Sperry:

Uh, and I just recently had a child and I'd love for her to enjoy the world

Tim Sperry:

the way we all have been able to do so.

Tim Sperry:

Uh, and also thrive in a healthy place that supports her.

Tim Sperry:

So my driving passion and my reasons why.

Todd Miller:

Very interesting.

Todd Miller:

And that's fascinating.

Todd Miller:

I mean, I love it when an entrepreneur.

Todd Miller:

You know is driven by their passions.

Todd Miller:

I think sometimes entrepreneurs are driven by The field that they ended up in and

Todd Miller:

suddenly they thought okay I'll just stay in this field, but uh, I love that and

Todd Miller:

I need to check out google scholar for sure And just so our audience knows And

Todd Miller:

I forgot to mention this earlier, we are doing challenge words this episode, and

Todd Miller:

I think in the future, I may use Google Scholar to find my challenge words.

Todd Miller:

But anyway, each of us on the show has been given a word by one of the

Todd Miller:

others that we've been challenged.

Todd Miller:

To work into the conversation.

Todd Miller:

So you, the audience can be listening to see what those are.

Todd Miller:

Maybe you already heard one or two.

Todd Miller:

I don't know.

Todd Miller:

Um, but at the end, we'll tell you whether we were successful or not at

Todd Miller:

working in, uh, our challenge words.

Todd Miller:

So, um, well, let's just for our audience, um, start at ground zero.

Todd Miller:

I mean, tell us some of the basics.

Todd Miller:

Uh, why is CO2 capture important?

Todd Miller:

Um, what is the overall goal of what you're doing?

Todd Miller:

And I love that you're driven partly by this little baby you have at home.

Todd Miller:

So that's exciting also.

Tim Sperry:

Absolutely.

Tim Sperry:

Yeah, no, thanks so much for that.

Tim Sperry:

Um, you know, as As we really look at the world today and we're

Tim Sperry:

emitting about 50 billion tons of CO2, which is a pretty big number.

Tim Sperry:

Um, just as we're developing countries and as we're increasing population, I think

Tim Sperry:

it's a challenge unless we get to absolute net zero, which today we effectively could

Tim Sperry:

never do that and get off hydrocarbons.

Tim Sperry:

As the way the world is currently set up, you know, it's going to take some time.

Tim Sperry:

So as we're continuing to emit more and more CO2, it's

Tim Sperry:

not actually getting better.

Tim Sperry:

It's getting worse from increased, uh, extreme heat, uh, extreme weather events.

Tim Sperry:

You know, we've, we've broken some really bad records this year.

Tim Sperry:

We've been above 1.

Tim Sperry:

5 degrees Celsius of warming for over 18 months.

Tim Sperry:

Not a great place to be because that's what we were trying to

Tim Sperry:

refrain from doing, uh, up till 2100.

Tim Sperry:

And.

Tim Sperry:

The real consensus is now in order for us to really help the planet to

Tim Sperry:

help do things about the climate, climate crisis, we need to remove CO2

Tim Sperry:

and removing CO2 is a big challenge.

Tim Sperry:

Um, there's a lot of novel technologies out there today, but they're able to

Tim Sperry:

do this much and we need a lot more.

Tim Sperry:

So it's really important that this It's getting a lot of attention, um, in all

Tim Sperry:

different circles, as you mentioned in the beginning, uh, and really the idea for

Tim Sperry:

removing carbon is how can we take carbon that's already in the atmosphere and

Tim Sperry:

then put it into a solid format where it can't re emit itself into the atmosphere,

Tim Sperry:

whether that's capturing it and then utilizing it in some form or fashion

Tim Sperry:

where it won't re emit, or whatever.

Tim Sperry:

Uh, make it into a super critical liquid state and injecting it down a

Tim Sperry:

class six well, which is a mouthful.

Tim Sperry:

Uh, and not the easiest thing to do either.

Tim Sperry:

Not a lot of classics wells and companies that can do that yet.

Tim Sperry:

Uh, so really, the idea is how can we.

Tim Sperry:

More effectively capture and remove some of the carbon that

Tim Sperry:

we've already put out there.

Tim Sperry:

And what are those technologies and how can we get them to scale?

Todd Miller:

Very good.

Todd Miller:

So I know that originally, as you went down, down this path,

Todd Miller:

you were using paint and coatings to capture carbon, capture CO2.

Todd Miller:

And now you've moved on to concrete.

Todd Miller:

Um, I assume the technology between the two is kind of similar.

Todd Miller:

I mean, which is more effective?

Todd Miller:

effective.

Todd Miller:

Uh, tell us a little bit about the difference between

Todd Miller:

those two different paths.

Tim Sperry:

Yeah.

Tim Sperry:

I mean, even though I'm, you know, the surface, they may look similar,

Tim Sperry:

they're a hundred percent different.

Tim Sperry:

Uh, you have a coating that has physical and chemical absorption capability of CO2.

Tim Sperry:

So it's bonding the CO2 molecules in and around and on the surface and in

Tim Sperry:

the matrix of, of whatever you have there from a paint or a coating.

Tim Sperry:

But it's not utilized.

Tim Sperry:

The CO2 molecules still stay intact.

Tim Sperry:

And if you were to heat that surface up enough, it would

Tim Sperry:

start releasing those generally.

Tim Sperry:

I don't think we're going to get to a point of heating it up enough,

Tim Sperry:

unless it's on fire or it's put into some extreme heat situation where

Tim Sperry:

it would release all of that CO2.

Tim Sperry:

Um, but the difference with that and what we're doing at carbon limits

Tim Sperry:

with our capture Creek technology, which is a CO2 capturing concrete.

Tim Sperry:

When the CO2 is absorbed, similarly to how it is on the coating, it's

Tim Sperry:

actually then interacting with the, they call them hydration products in

Tim Sperry:

the concrete, so the cement and the other, uh, materials in the concrete.

Tim Sperry:

And it's, transforming, and it's actually a chemical reaction that turns

Tim Sperry:

the CO2 molecule into a solid mineral.

Tim Sperry:

So it's changing its chemistry and making it into a solid mineral where that will

Tim Sperry:

stay in solid mineral form unless you heat it above 550 degrees Celsius, which is

Todd Miller:

So I'm curious, how does the amount of, you know, through your

Todd Miller:

process and what you're doing, how does the amount of CO2 or carbon you can

Todd Miller:

capture compare to the amount of CO2 made in the production of concrete?

Tim Sperry:

So that depends.

Tim Sperry:

Um, if you look at.

Tim Sperry:

Traditional concrete and you look at these new concretes.

Tim Sperry:

I'm sure you guys have have seen and heard and had had some experience.

Tim Sperry:

Their original Portland cement was generally mixed with sand, gravel, air

Tim Sperry:

and water to create concrete today.

Tim Sperry:

It's more.

Tim Sperry:

Limestone based cements, natural puzzle on basements, fly ash and

Tim Sperry:

slag that are actually reducing some of the carbon in there already.

Tim Sperry:

And our product just further makes it more sustainable.

Tim Sperry:

From a percentage basis, it's hard to say we can capture X number of kilograms

Tim Sperry:

of CO2 per cubic yard, and that that number can really go on a sliding scale.

Tim Sperry:

So we could, in effect, maybe capture an additional couple of

Tim Sperry:

percent, 10, 20 percent of what was made in that original volume.

Tim Sperry:

Carbon event when you're making the cement, because that's majority of that

Tim Sperry:

carbon footprint comes from, uh, it's just really dependent on the type of concrete,

Tim Sperry:

the use case, the compressive strength.

Tim Sperry:

Uh, and if it's a road versus a building, uh, if it's a concrete

Tim Sperry:

block, which is much more porous.

Tim Sperry:

Uh, so there's not 1 clear answer.

Tim Sperry:

It's just depends on the type of concrete and the use case there.

Tim Sperry:

It captures a good amount of CO2, uh, compared to concrete that's

Tim Sperry:

capturing a very limited amount of CO2, because concrete naturally does

Tim Sperry:

absorb CO2, but once it absorbs it and it gets in and on that surface

Tim Sperry:

and creates more impenetrable barrier.

Tim Sperry:

It's kind of like a steak.

Tim Sperry:

If you're grilling on the outside and you sear it out, you're not going

Tim Sperry:

to get too much on the inside there.

Tim Sperry:

From a sear level, you're going to cook it, but it's not going

Tim Sperry:

to go all the way through.

Todd Miller:

Gotcha.

Todd Miller:

Well, I think that's interesting.

Todd Miller:

I think one thing, I think a lot of folks, when you think of concreting,

Todd Miller:

you think of your driveway.

Todd Miller:

And people don't realize how many buildings are simply concrete based.

Todd Miller:

in their structure now as well.

Todd Miller:

Um, so that's really kind of what you're going after, I assume, is

Todd Miller:

more that, you know, where it's being used to actually build the building,

Todd Miller:

maybe not necessarily someone's driveway in the front of their house.

Todd Miller:

Is that correct?

Todd Miller:

Or am I off on that?

Tim Sperry:

Um, honestly, we want it everywhere.

Tim Sperry:

Gotcha.

Tim Sperry:

You know, we, we just worked with, uh, with a housing developer here

Tim Sperry:

in Florida, and we did an initial flat work product, uh, project.

Tim Sperry:

So you're thinking sidewalks, you're thinking driveways, then you're

Tim Sperry:

going, uh, to your concrete slabs, uh, for the foundation of the houses,

Tim Sperry:

you can go into exterior stuff.

Tim Sperry:

And then down here in South Florida, we have a bit of, uh, quite a bit of

Tim Sperry:

concrete tiles and rooftop pavers that you can put on there as well, which

Tim Sperry:

lasts up to 50 years, which could capture a lot of CO2, as you have.

Tim Sperry:

Uh, much thinner concrete that has much more exposure and

Tim Sperry:

ability to actually capture, uh, and, and, and utilize that CO2.

Todd Miller:

So does what you're doing change the physical property

Todd Miller:

of the concrete in any way?

Todd Miller:

Does it, you know, maybe make it stronger over time or any

Todd Miller:

change at all like that happen?

Tim Sperry:

Exactly.

Tim Sperry:

So we, when we made this.

Tim Sperry:

The whole idea was, hey, how can we capture as much carbon as possible and

Tim Sperry:

then store it into concrete where it'll stay for up throughout the service life

Tim Sperry:

and even at the end of its service life when you break it and grind it down.

Tim Sperry:

But what we found was that Because the CO2 being captured is creating

Tim Sperry:

solid carbonates, filling in some microcracks, some of the pores, it's

Tim Sperry:

actually making the concrete stronger.

Tim Sperry:

So we can actually increase the compressive strength, making it

Tim Sperry:

stronger, potentially last longer, uh, and greener and more sustainable,

Tim Sperry:

and potentially able to mitigate and, and reduce the amount of maintenance.

Tim Sperry:

It as a byproduct of its capturing co2 increases compressive strength.

Todd Miller:

This may seem like a silly question, but i'm going to

Todd Miller:

answer it anyway or ask it anyway How do we know what you're doing works?

Todd Miller:

I mean, how do you measure this?

Todd Miller:

It seems like a tough thing to to really measure or or uh quantify.

Tim Sperry:

Yeah Um, so there's a whole consortium.

Tim Sperry:

It's it's called it's with nist and it's actually government academia industry

Tim Sperry:

It's all of these, um, different groups coming together to determine a one, I

Tim Sperry:

don't know, one solution pathway for, okay, how do we quantify the amount

Tim Sperry:

of carbon being taken up, because they also want to integrate that into what

Tim Sperry:

happens naturally into concrete as, you know, look, We love cement and

Tim Sperry:

concrete manufacturers because we see ourselves having a great partnership and

Tim Sperry:

relationship with them to help make their, make their offerings more sustainable.

Tim Sperry:

They're doing the world a great service and giving it platform and giving it the

Tim Sperry:

foundation to actually live on, which is, you know, all of our roads, all of

Tim Sperry:

our bridges, all of our homes, all the concrete that kind of don't see, you know,

Tim Sperry:

we're, we're all probably sitting on some concrete slab right now, effectively.

Tim Sperry:

Um, so we've, we've actually been working with universities

Tim Sperry:

like University of Miami.

Tim Sperry:

We initially were working, um, with a couple of other universities when we were

Tim Sperry:

based up in Indianapolis, and we're also working with third party labs that take

Tim Sperry:

the concrete and then they determine how much solid carbonates are built up in it.

Tim Sperry:

compared to another piece of concrete without our technology, how much

Tim Sperry:

solid carbonates are built up in there over the same period of time.

Tim Sperry:

And then they just create whatever that delta is, how much more CO2

Tim Sperry:

are we capturing and storing?

Tim Sperry:

So you're actually able to quantify those solid carbonates, i.

Tim Sperry:

e.

Tim Sperry:

the amount of CO2 that's been mineralized into the concrete.

Tim Sperry:

Now the test methods are ASTM, but they're still challenging to really

Tim Sperry:

fully, uh, you know, everyone's wrapping their head around there.

Tim Sperry:

Having a consensus on on those.

Ethan Young:

Um, you mentioned something about the, uh, like, you know, They

Ethan Young:

can still capture concrete throughout a service life Is there sort of

Ethan Young:

like a saturation point where it's captured like the maximum amount of

Ethan Young:

co2 it can capture and then it's no longer Is it continuously, you know?

Tim Sperry:

That's exactly right So it's effectively like a sponge and you can only

Tim Sperry:

put so much water until that sponge is overwhelmed But we did uh, we've received

Tim Sperry:

Two grants from the, uh, Department of Defense, uh, in partnership with the U.

Tim Sperry:

S.

Tim Sperry:

Army Corps of Engineers.

Tim Sperry:

To actually create feasibility reports, studies, R& D, and show them what we're

Tim Sperry:

doing compared to regular concrete.

Tim Sperry:

And let's say you have a block of regular concrete, and there's a lot of

Tim Sperry:

carbonation on the top, but it doesn't allow any more CO2 to seep in any further.

Tim Sperry:

Versus ours, which accelerates and increases that depth and

Tim Sperry:

increases the amount of carbonation.

Tim Sperry:

We may have gone 70 percent in, and they only went 30 percent in.

Tim Sperry:

So if we go to a hundred, it's just going to stop.

Tim Sperry:

And then it's just, you know, people are, well, what, what

Tim Sperry:

happens to the concrete then?

Tim Sperry:

Well, it serves its purpose.

Tim Sperry:

It's still concrete.

Todd Miller:

So what is your go to market strategy?

Todd Miller:

How are you bringing this technology to market?

Todd Miller:

It seems like, uh, such a vast market out there.

Todd Miller:

I'm just kind of curious how you tackle that.

Tim Sperry:

You really, really cognizant of the producers themselves, you know, a

Tim Sperry:

producer that's been making concrete the same way for, uh, 20, 30, 50, 100 years

Tim Sperry:

doesn't want to do new stuff, right?

Tim Sperry:

So how do we integrate without, you know, changing that process with adding,

Tim Sperry:

adding a whole bunch of new equipment?

Tim Sperry:

And then also, how do we make them the heroes?

Tim Sperry:

How do we help them, uh, from an adoption standpoint and benefit them?

Tim Sperry:

So we've seen our pathways going the licensing path.

Tim Sperry:

Uh, to actually license our formula to say, Hey, take material A, which is our

Tim Sperry:

natural pozzolan that works this way and has this functionality and material

Tim Sperry:

B, which is our catalyst and add them to the concrete and their specific

Tim Sperry:

concrete at a certain dosage rate to create that carbon capturing effect.

Tim Sperry:

So we work with them hand in hand to say, okay.

Tim Sperry:

Here's how you can make CO2 absorbing and CO2 capturing concrete.

Tim Sperry:

And then we in turn generate carbon credits every time they deploy a

Tim Sperry:

cubic yard of concrete or build a road or a bridge or something else.

Tim Sperry:

Uh, and then we share some of those proceeds as a revenue share for the

Tim Sperry:

carbon credits, and those carbon credits are great for two reasons.

Tim Sperry:

One, uh, carbon credit, uh, signifies a ton of CO2 that's

Tim Sperry:

being captured, stored, or removed.

Tim Sperry:

And two, uh, it's a third party, uh, quantification, and then you also then

Tim Sperry:

can monetize those and sell them to your big tech companies, governments,

Tim Sperry:

and, you know, financial institutions, investors, others that are buying

Tim Sperry:

carbon credits for whatever purposes they have, reducing their carbon

Tim Sperry:

footprint, or meeting ESG goals,

Todd Miller:

So what do you figure ends up being the final cost to, uh, you

Todd Miller:

know, however the concrete is being used?

Tim Sperry:

So that's a really good question.

Tim Sperry:

Everybody wants to be green and sustainable, but guess what?

Tim Sperry:

No one wants to pay for it, right?

Tim Sperry:

Absolutely.

Tim Sperry:

Yeah.

Tim Sperry:

And, you know, that was, uh, that was one of our biggest pieces with, all right,

Tim Sperry:

how do we work out these financials?

Tim Sperry:

How do we do the economics here where we can create either cost neutrality?

Tim Sperry:

Or a slight green premium, or maybe even a green, uh, an actual financial return.

Tim Sperry:

So in some instances, we're able to And for different products, maybe for a

Tim Sperry:

concrete product, we have some precast companies that work with us to create

Tim Sperry:

products, they can charge a green premium, or they can just charge the higher tier

Tim Sperry:

of pricing because it's green, it's sustainable, it's capturing CO2, And

Tim Sperry:

for them, it's easier to kind of chew on a little bit of cost, but for the mass

Tim Sperry:

market, and for the ready mix market, which is the majority of what's being

Tim Sperry:

deployed, we got to try to be really understanding and trying to be really

Tim Sperry:

sensitive to those prices, at least today.

Tim Sperry:

You know, there's a small percentage that will pay for more.

Tim Sperry:

So our main, our main objective was, okay, well, how do we get

Tim Sperry:

these materials cheap enough?

Tim Sperry:

And then how do we get a value proposition of a carbon credit that might be able

Tim Sperry:

to pay for those materials when we share those revenues to create the cost

Tim Sperry:

neutrality, or there's some instances, uh, to your question about how does

Tim Sperry:

it affect, you know, the concrete.

Tim Sperry:

If it increases performance enough, you can actually take out some of the

Tim Sperry:

cement to create a cost savings that counteracts that additional cost.

Tim Sperry:

So those are kind of our pathways that that we've found successful.

Todd Miller:

What are you seeing down the, the pike?

Todd Miller:

I mean, I assume that you're seeing, you know, eventually mandates and

Todd Miller:

things are going to really support what you're doing, uh, and encourage it.

Todd Miller:

Um, can you talk to us a little bit about, you know, how, how you might

Todd Miller:

see that playing out in future years?

Todd Miller:

And maybe it's a crapshoot right now.

Todd Miller:

I don't know, but, uh, what, what

Tim Sperry:

are your thoughts there?

Tim Sperry:

What I'm seeing more from my side of my perspective is there's a

Tim Sperry:

huge customer driven demand, right?

Tim Sperry:

Everyone wants more, and I'm sure you guys are seeing a little bit of this too,

Tim Sperry:

you know, sustainable building materials, sustainable that, or more at least

Tim Sperry:

transparency around, um, you know, an EPD, uh, an environmental product declaration.

Tim Sperry:

So as the competitor A has a sustainable solution that maybe is more marketable

Tim Sperry:

and giving them a leading edge for getting more business and winning

Tim Sperry:

more bids, competitor B is looking for another solution or that solution also.

Tim Sperry:

It's a great.

Tim Sperry:

So we're seeing that competitive landscape actually creating some

Tim Sperry:

opportunity for more adoption.

Tim Sperry:

Uh, and then the carbon credit piece is big because you can quantifiably

Tim Sperry:

convey an environmental attribute of, Hey, this concrete has 50 percent

Tim Sperry:

less CO2 than traditional concrete.

Tim Sperry:

It's great.

Tim Sperry:

That's a good thing for everybody.

Tim Sperry:

Um, so I think we're seeing, I think we're seeing that more than some of

Tim Sperry:

the potential regulations and mandates.

Tim Sperry:

And once those regulations and mandates come in, and I think there's

Tim Sperry:

a little bit of a hold back for some of those regulations and mandates.

Tim Sperry:

And I've seen some, some, some data on this, that there's just

Tim Sperry:

not enough sustainable material to satisfy the whole of the concrete.

Tim Sperry:

Let's say everyone wanted to go to fly ash and slag.

Tim Sperry:

If the whole industry went to fly ash and slag to reduce 25 percent of

Tim Sperry:

their carbon footprint, we'd run out of fly ash and we'd run out of slag.

Tim Sperry:

Potentially.

Tim Sperry:

So if that was the case, then you're mandating something that

Tim Sperry:

couldn't effectively be done.

Tim Sperry:

So you're kind of stuck between a rock and a hard place.

Tim Sperry:

Gotcha.

Tim Sperry:

So I think it's, it's getting there, but the solutions need to scale up.

Tim Sperry:

And the other piece is how does ASTM and these other specification agencies, Keep

Tim Sperry:

up with the rate of innovation, you know, they're generally not great at that.

Todd Miller:

Yeah, yeah, you're right.

Todd Miller:

That's all that all is a process and takes time.

Todd Miller:

Very interesting.

Todd Miller:

This is just a fascinating field that you get when you find yourself in and

Todd Miller:

you're really, truly a pioneer kind of figuring out all the angles of this.

Todd Miller:

So I'm impressed.

Todd Miller:

Well.

Todd Miller:

You've also introduced a product recently called CoolCrete, which I understand

Todd Miller:

is a concrete additive that helps to enhance solar reflectance and emittance.

Todd Miller:

Um, sounds pretty fascinating.

Todd Miller:

Tell us a little bit about that as well.

Todd Miller:

And I, I assume that just kind of rides right along with the carbon capture.

Tim Sperry:

Uh, you're right.

Tim Sperry:

And in fact, it does.

Tim Sperry:

Uh, I would just call this the sister technology.

Tim Sperry:

Really excited about CoolCrete because.

Tim Sperry:

You know, today, this year, we've had the most 110 degrees plus

Tim Sperry:

days in recorded human history.

Tim Sperry:

We've also experienced the two hottest days in recorded human history as well.

Tim Sperry:

Uh, back in July, which again, not, not good things, but as the world's

Tim Sperry:

getting hotter, how do we adopt to some of these things to help us live better

Tim Sperry:

lives and not have any issues with, you know, potentially heat related illnesses

Tim Sperry:

and, you know, potentially worse.

Tim Sperry:

So cool.

Tim Sperry:

Crete was Made as a potential solution to urban heat island effect where

Tim Sperry:

when you have a very densely populated area with a lot of concrete building

Tim Sperry:

materials and it's a hot sunny day, those materials not being organic materials

Tim Sperry:

are actually absorbing this heat and then radiating it out your downtown

Tim Sperry:

where I am close to downtown Miami.

Tim Sperry:

The city could be 10, 20 degrees hotter than ambient temperature

Tim Sperry:

in the middle of the city.

Tim Sperry:

So instead of 100 degree hot, humid day, which sucks down here, by the

Tim Sperry:

way, been in South Florida this time of the year, um, it could be 110, 120.

Tim Sperry:

And now that's not just uncomfortable, but it's potentially dangerous for us.

Tim Sperry:

So with cool Crete, we're using, it's the first, first that we know of, uh, cement

Tim Sperry:

replacement that replaces cement, lowering the carbon footprint 10, 20, 30, 40%.

Tim Sperry:

And then it gives the concrete the properties of being highly reflective

Tim Sperry:

to the sun and the UV coming down.

Tim Sperry:

So it doesn't absorb that heat.

Tim Sperry:

It doesn't radiate that heat.

Tim Sperry:

It's more effective at releasing that heat.

Tim Sperry:

And then the thermal admittance is.

Tim Sperry:

How effectively does it minimize the amount of thermal conductivity,

Tim Sperry:

the amount of heat that's radiated into a building or a home?

Tim Sperry:

Let's say that this is on the outside of a building or a rooftop.

Tim Sperry:

Now, why is that important and why I'm really excited about it?

Tim Sperry:

Say you have a concrete roof in a commercial building, you

Tim Sperry:

know, uh, retail or your house.

Tim Sperry:

If you have a darker roof, if you have a roof that absorbs a lot of

Tim Sperry:

heat and that transfers heat into your home, your air conditioning is

Tim Sperry:

turning on more, more frequently to counteract that heat to keep it cooler.

Tim Sperry:

You know, not great for the AC, can definitely burn them out faster.

Tim Sperry:

On top of that, it's not great for your electric bill.

Tim Sperry:

So let's say you're increasing your electricity bill 10, 20, 30,

Tim Sperry:

40 percent because of this heat.

Tim Sperry:

We could potentially be that solution to minimize that.

Tim Sperry:

Uh, let's, you know, our, our, our results with one of our

Tim Sperry:

partners that's launching concrete.

Tim Sperry:

And I, that's why I'm talking about roots is a rooftop paver.

Tim Sperry:

And their results from the control without our technology to the paper

Tim Sperry:

with our technology is we're reducing about up to 10 to 11 degrees Celsius.

Tim Sperry:

You're almost 20 degrees Fahrenheit there.

Tim Sperry:

Every 1 degree Celsius that you could cool the interior of a building.

Tim Sperry:

You could reduce 3 to 5 percent of your electricity bill for cooling.

Tim Sperry:

And that's a, you know, a pretty significant number.

Tim Sperry:

If, if that 10, 10 degrees Celsius translated directly into 10

Tim Sperry:

degrees Celsius of cooling in your building, 30 to 50 percent of your

Tim Sperry:

cooling bill would be reduced.

Tim Sperry:

That's a big number and we can't make a claim because every roof, every

Tim Sperry:

installation, every air conditioning, every property would be different.

Tim Sperry:

So you have to really see, you know, what are those variables to determine how much

Tim Sperry:

potential energy reduction we can achieve.

Tim Sperry:

But the other big one is data centers.

Tim Sperry:

Data centers are super energy hungry, and if you keep those

Tim Sperry:

hot, they need to keep cooler.

Tim Sperry:

We can cool those down.

Tim Sperry:

We could put it on sidewalks.

Tim Sperry:

You could put it in around roads.

Tim Sperry:

It reduces the surface level temperature everywhere.

Todd Miller:

Well, I love that.

Todd Miller:

And of course, in the metal roofing industry, we've worked

Todd Miller:

with that for a number of years.

Todd Miller:

Also, in terms of coatings and things to make our products more reflective

Todd Miller:

and emissive, we've worked with a lot with Florida Solar Energy Center

Todd Miller:

there at UCF and Oak Ridge National Laboratory, Berkeley, Lawrence Berkeley

Todd Miller:

National Lab as well, and a lot of great research being done into that area.

Todd Miller:

Um, another area that we're seeing, and I'll just throw this

Todd Miller:

out there, that a lot of work is being done is, um, thermal breaks.

Todd Miller:

And so, you know, how can you include a thermal break in with a concrete

Todd Miller:

product in order to help minimize that heat conduction as well?

Todd Miller:

So cool stuff you're doing.

Todd Miller:

Any thoughts on what might be next to your company for your company?

Todd Miller:

You are, uh, uh, over.

Todd Miller:

What do I say here?

Todd Miller:

He's just really pushing the envelope in so many areas.

Tim Sperry:

Yeah.

Tim Sperry:

You know, um, if my team would let me, I would create nonstop.

Tim Sperry:

Um, you know, I love coming up with these new inventions.

Tim Sperry:

I have a bunch of them, but, you know, staying the path of, you know, keeping

Tim Sperry:

my blinders on so we can really create a significant positive environmental impact.

Tim Sperry:

And then we want to also inspire other companies and other founders, other

Tim Sperry:

entrepreneurs and other inventors to create more solutions similar to this.

Tim Sperry:

You know, I was just, we had a town hall for our company yesterday,

Tim Sperry:

our first town hall for the year.

Tim Sperry:

You know, I was saying at the end, look, if this was 10 years ago, Carbon Limit

Tim Sperry:

would probably be a charity because companies like this just weren't really

Tim Sperry:

a big deal back then they weren't really, you know, something that could create

Tim Sperry:

massive wealth or had huge valuations because what we were doing was too

Tim Sperry:

related on, you know, either credits or other things to actually create value.

Tim Sperry:

Um, So for us, for what's next, it's really creating these meaningful and

Tim Sperry:

these significant partnerships with the cement and concrete industry and the

Tim Sperry:

producers and then also very large project developers, you know, working with data

Tim Sperry:

centers, working with, um, and we're actually, you know, still in process,

Tim Sperry:

but we've been in the Middle East quite a bit, uh, to work and try to find ways to

Tim Sperry:

partner with some of these giga projects, which we're currently engaging with.

Tim Sperry:

So just really excited about where we can go with this technology, how we can

Tim Sperry:

help benefit not only ourselves and other concrete producers, but you know, the

Tim Sperry:

society and the environment altogether.

Tim Sperry:

Uh, so we just look for these win, win, win partnerships.

Tim Sperry:

And, and we're really excited about it more so that, you know, when

Tim Sperry:

we first started this company, um, back in 2021, Uh, when we did our

Tim Sperry:

customer discovery, we were getting a bunch of, yeah, yeah, yeah, yeah.

Tim Sperry:

Like, sounds cool.

Tim Sperry:

You know, no one cared.

Tim Sperry:

Nobody cared.

Tim Sperry:

And then October was the shift where the Global Cement and Concrete

Tim Sperry:

Association said, okay, we're going to net zero and we're reducing 25

Tim Sperry:

percent of carbon footprint by 2030.

Tim Sperry:

That's tomorrow in that industry.

Tim Sperry:

So all of a sudden, all those calls that were pretty cold called back to us

Tim Sperry:

and they're, Hey, how about that stuff?

Tim Sperry:

So, you know, the interest and the rate of adoption and just like the,

Tim Sperry:

where the world is today is really exciting for a company like ours.

Tim Sperry:

So it gives us a lot of validation.

Tim Sperry:

It gives the team a lot of motivation.

Tim Sperry:

And, you know, we surround ourselves with such amazing human beings that are

Tim Sperry:

doing things that are helping not only.

Tim Sperry:

You know, themselves, but their families, future generations in the world.

Tim Sperry:

So it's, it's an exciting place for us.

Todd Miller:

Well, I love the fact that you're that entrepreneur that

Todd Miller:

is always pushing and want to be there developing and leading the way.

Todd Miller:

And I know sometimes I can try that in our company and, um, people are like, um,

Todd Miller:

yeah, Todd, but, uh, we're carnivores.

Todd Miller:

We like to eat.

Todd Miller:

So we also have to be doing what we're doing to eat every day as well.

Todd Miller:

But, uh, no, that's great stuff.

Todd Miller:

And I think that's how the advancements take places.

Todd Miller:

Yeah.

Todd Miller:

You got to have somebody that's driving those advancements and has that kind of,

Todd Miller:

uh, curiosity, uh, to keep pushing ahead.

Todd Miller:

So cool stuff.

Todd Miller:

Well, um, Tim, that's been a great time talking to you.

Todd Miller:

We're kind of close to wrapping up what we sort of call the business end of things.

Todd Miller:

Is there anything we haven't covered today that you wanted to

Todd Miller:

be sure to share with our audience?

Tim Sperry:

Uh, no, I think, uh, this is a great conversation.

Tim Sperry:

Always like to share and always like to find what's relatable and what's good

Tim Sperry:

and what will help, you know, provide more education about what we're doing

Tim Sperry:

because we're solving an invisible problem and, you know, it's, it's,

Tim Sperry:

it's good to create that education.

Tim Sperry:

So, uh, I really enjoyed the conversation.

Todd Miller:

Great.

Todd Miller:

Well, we have as well.

Todd Miller:

Well, uh, we'd like to invite you to do something we invite every

Todd Miller:

guest to do, which is what we call our rapid fire questions.

Todd Miller:

Um, Tim, these are seven questions.

Todd Miller:

They're going to be out of the blue.

Todd Miller:

You have no idea what we're going to ask.

Todd Miller:

Are you up to the challenge of rapid fire?

Todd Miller:

I'm up to challenges, yes.

Todd Miller:

Awesome.

Todd Miller:

Well, we will alternate asking.

Todd Miller:

Ethan, you want to ask question number one?

Ethan Young:

Yeah, I can do the first one.

Ethan Young:

What's a product or service that you've acquired recently that was

Ethan Young:

like a real game changer for you?

Tim Sperry:

Product or service that we've acquired as a company?

Ethan Young:

Or you personally, either way.

Tim Sperry:

So I think it was our, our CRM that we acquired because as we're

Tim Sperry:

formalizing and going from startup to growth scale up mode, you know,

Tim Sperry:

going from a very loosely held thing to like, Hey, we can see how actually

Tim Sperry:

everything looks and where everything is.

Tim Sperry:

That was, I think a huge, uh, a huge boost and a huge kind of evolution for us.

Tim Sperry:

So.

Tim Sperry:

It's called ClickUp and it was helping us with the CRM and kind

Tim Sperry:

of connecting all of our teams.

Tim Sperry:

Once, once we're bigger than fitting around a small

Tim Sperry:

table, that was huge for us.

Ethan Young:

Gotcha.

Ethan Young:

Yeah.

Ethan Young:

That definitely makes a big difference.

Ethan Young:

You said that was QuickUp or ClickUp?

Tim Sperry:

Uh, ClickUp.

Tim Sperry:

Oh, okay.

Tim Sperry:

Yeah.

Tim Sperry:

Yeah.

Tim Sperry:

And those can be like integrated into Salesforce and other things

Tim Sperry:

that we're, we're now looking at too.

Tim Sperry:

Yeah.

Todd Miller:

Well, shout out to ClickUp and, uh, we'll include a lot of this

Todd Miller:

stuff in the show notes as well for folks.

Todd Miller:

So, um, question number two, if I asked the elementary school, Tim,

Todd Miller:

what he wanted to be when he grew up, what would he have told me?

Tim Sperry:

I always wanted to be an inventor.

Tim Sperry:

I always invented things.

Tim Sperry:

I even made like, uh, I made stuff when I was a kid.

Tim Sperry:

So I always dreamed of really inventing things and then traveling a lot.

Tim Sperry:

And I got both of those, but now I want to dial back that traveling a lot

Tim Sperry:

part because I was traveling like every week and it was getting a little crazy.

Tim Sperry:

So, uh, I, I was right on cue.

Ethan Young:

That's awesome.

Ethan Young:

Alrighty.

Ethan Young:

Next question is kind of taking it the other direction, but what are

Ethan Young:

your plans after you retire from working on, you know, All these

Ethan Young:

energy saving technology and stuff.

Ethan Young:

Are you going to kind of be a philanthropist still going after

Ethan Young:

the same goals or you think something totally different?

Tim Sperry:

Um right now I want to Be more on the philanthropist side as

Tim Sperry:

well as on the creative platform for other technologies other inventors

Tim Sperry:

Other potential businesses, you know, I've been through a lot of different

Tim Sperry:

accelerators from tech stars to Google's climate change accelerators and a lot

Tim Sperry:

of these other accelerators where they help these businesses become formal

Tim Sperry:

businesses and actually go from, you know, napkin napkin sketch to actual

Tim Sperry:

business model and financial model.

Tim Sperry:

I'd love to help others to create these businesses and also, you know, um,

Tim Sperry:

selfishly, I want a platform that's got all the elements around it that

Tim Sperry:

could create all of my ideas and my inventions and rapid fire, rapid pace.

Tim Sperry:

So I, I, I would love to just continue to help.

Tim Sperry:

Other people achieve and realize their dreams and bring

Tim Sperry:

other things to the world.

Tim Sperry:

Uh, I call 'em society plus businesses.

Tim Sperry:

Businesses that help society and that help the environment.

Tim Sperry:

Something that's good for everybody.

Todd Miller:

Yeah, I love it.

Todd Miller:

Awesome.

Todd Miller:

Question number four.

Todd Miller:

Well, you said you've traveled a lot and you enjoyed that at

Todd Miller:

least to a, to a certain extent.

Todd Miller:

But do you still have a bucket list vacation out there, something

Todd Miller:

you'd like to do someday?

Todd Miller:

I'm a lot.

Todd Miller:

Um,

Tim Sperry:

yeah, a lot.

Tim Sperry:

I want to go all over Asia.

Tim Sperry:

Um, I haven't had a chance to do so much that, uh, specific locations

Tim Sperry:

going into like Thailand, Hong Kong.

Tim Sperry:

Um, I'm, I'm, I'm also more of a, even though I live in this

Tim Sperry:

South Florida paradise and tropical area, like, I love it.

Tim Sperry:

Like I love heat.

Tim Sperry:

Um, I know they have this new thing that's called cool Cations where people

Tim Sperry:

are going to like Copenhagen and cooler places because it's getting hotter.

Tim Sperry:

I love the heat.

Tim Sperry:

You know, so I love being in tropical places.

Tim Sperry:

I'm from Southern California originally, so I also like to have

Tim Sperry:

mountains in the background, which is the one thing that I'm missing here.

Tim Sperry:

So places like that, Bora Bora, you know, cool spots like that, that I

Tim Sperry:

haven't been to yet that I look to go to.

Ethan Young:

Very

Tim Sperry:

nice.

Ethan Young:

Um, this next question, this one's always an interesting one for

Ethan Young:

me to hear what people's answers are.

Ethan Young:

But if you could instantly master any skill, what would that skill be?

Ethan Young:

Speed reading.

Ethan Young:

Mm, that's a useful one, yeah.

Ethan Young:

I like

Tim Sperry:

that.

Tim Sperry:

Yeah, I, I love reading.

Tim Sperry:

I, and when I say reading, I mean typically listening to books because

Tim Sperry:

I just don't have enough time to read.

Tim Sperry:

I listen to at least a book a week, sometimes two.

Tim Sperry:

Uh, but if I could speed read as well, um, cause I listen to, I can speed

Tim Sperry:

listen right now really well, but the speed reading I want to get done.

Todd Miller:

Well, that said, I'm going to change what I

Todd Miller:

planned for the next question.

Todd Miller:

Um, what is a good book you've read or listened to recently that you

Todd Miller:

would recommend to our audience?

Tim Sperry:

Oh, I gave this out as our company Bible.

Tim Sperry:

Um, you know, a couple of years back, uh, was Buddha and the

Tim Sperry:

badass by vision Lafayette.

Tim Sperry:

He's the founder of mind Valley and to have these really cool courses on, on

Tim Sperry:

different parts of life and mastery.

Tim Sperry:

And, uh, there's actually one by Jim quick, which is speed reading.

Tim Sperry:

So I can get into that one too.

Tim Sperry:

Um, so that one I, I think is usually good for a general audience

Tim Sperry:

because it can apply to everyone.

Tim Sperry:

It's, it's not a business book and it's called Buddha.

Tim Sperry:

It is and it isn't a business book and it's kind of a personal

Tim Sperry:

development book as well.

Tim Sperry:

And it's Buddha and the Badass, but it's nothing to do with religion.

Tim Sperry:

Um, so a really cool one that I, I, I'm always recommending

Tim Sperry:

on a generalized basis.

Tim Sperry:

Some of the books that I listen to are super crazy and unless you're

Tim Sperry:

ready for it, you won't get it.

Todd Miller:

Well, if you're that kind of volume of reading and listening

Todd Miller:

to books, I understand that too.

Todd Miller:

Good stuff.

Todd Miller:

Yeah.

Todd Miller:

Well, Badass.

Todd Miller:

I think I've heard of that, but I'm going to check it out.

Ethan Young:

Thank you.

Ethan Young:

Um, all right, last question.

Ethan Young:

Um, what do you want to be remembered for at the end of your days?

Ethan Young:

How

Tim Sperry:

much impact and how many people I've helped.

Tim Sperry:

You know, I, I, I love to, I love to do things that, that I can, you know,

Tim Sperry:

help create with others and help others become the best version of themselves.

Tim Sperry:

Um, and I just love having these great mutually beneficial relationships.

Tim Sperry:

And, you know, sometimes it's more fulfilling just to give than it is to get.

Tim Sperry:

Uh, so really that impact, um, and then how many people I've helped.

Todd Miller:

Good answer.

Todd Miller:

Well, Tim, this has been fantastic.

Todd Miller:

Thank you again.

Todd Miller:

For folks who would like to get in touch with you or perhaps learn

Todd Miller:

more about Carbon Limit or, or Coolcrete, um, how can they do that?

Todd Miller:

Give us some, uh, websites or whatever works.

Tim Sperry:

Sure.

Tim Sperry:

So I'm the worst social media person and maybe I shouldn't create a selfie.

Tim Sperry:

The flame prophecy on that one, but I am sometimes on LinkedIn.

Tim Sperry:

So if you want to try to reach me on LinkedIn, um, you can certainly find

Tim Sperry:

me, Tim Sperry, uh, carbon limit.

Tim Sperry:

And, uh, there's also carbon limit.

Tim Sperry:

com and with carbon limit.

Tim Sperry:

com, you can look at capture, create our CO2 capturing

Tim Sperry:

concrete as well as cool create.

Tim Sperry:

Uh, and that's, that's, that's generally the best way to catch me or

Tim Sperry:

to learn a little bit more about us.

Todd Miller:

Very good.

Todd Miller:

Well, um, so our audience knows, I think we were all successful

Todd Miller:

working in our challenge boards.

Todd Miller:

Ethan, your word was?

Todd Miller:

Mine was philanthropist.

Todd Miller:

You got it

Ethan Young:

in there in your question.

Ethan Young:

Good job.

Ethan Young:

I did.

Ethan Young:

I modified one of the questions.

Ethan Young:

That's usually my trick if I can't find another spot.

Ethan Young:

So.

Ethan Young:

And Tim, your word was?

Tim Sperry:

Zoology.

Tim Sperry:

And I got it in like, My first, uh, little spit.

Tim Sperry:

So, so

Todd Miller:

what was it like taking a zoology class?

Todd Miller:

Did you enjoy that?

Tim Sperry:

Uh, you know, I actually did take the class.

Tim Sperry:

I didn't just make that up to fit the word in there, but yeah, it was good.

Tim Sperry:

It was, it was, um, it was my first year at University of Wisconsin

Tim Sperry:

Madison and it was interesting.

Tim Sperry:

So, uh, I really, I really enjoyed the college experience, um, at that point.

Tim Sperry:

So I had some really interesting classes.

Tim Sperry:

The one that always sticks out to me is called the brain demystified.

Tim Sperry:

And the first day of class, they had a 3d projector that they had a real

Tim Sperry:

live human brain on and they cut it up.

Tim Sperry:

And I was like, wow, this is cool.

Tim Sperry:

It was the first day of class.

Tim Sperry:

So, and I think that was right after my zoology class.

Tim Sperry:

So it's why it stuck out so much.

Todd Miller:

Good stuff.

Todd Miller:

Well, the word I had was carnivore, which I kind of worked in

Todd Miller:

awkwardly, but I got it in there.

Todd Miller:

So it

Ethan Young:

worked.

Ethan Young:

Yeah.

Todd Miller:

Well, thank you again, Tim.

Todd Miller:

That's been great.

Todd Miller:

Thank you for being on the show.

Todd Miller:

Yeah.

Todd Miller:

It's been a pleasure.

Todd Miller:

Really great to be on with you guys.

Todd Miller:
