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:And thank you to our audience for tuning into this very special
