[23:26] “My intention and mission [with Tap] is that people will see how much more profitable it is to dispense tap water than it is bottled water. And because the emissions and waste are less, and regulation is […] more significant with tap water than bottled water, I hope that the market demand will shift towards the better and less expensive product… Tap water over bottled water.”

[14:23] “There's that famous quote from Marc Andreessen “software's eating the world” […]. And the idea there was software will go one by one through every major sector of the economy and transform it over time. And that I think, has generally proven to be true. I think you can say something similar about climate. In the sense that emissions come from nearly every major sector of the economy and if we're truly going to decarbonize, then basically every one of those industries needs to transform in some way or another in order to decarbonize. So climate, I think, will end up eating the world in a slightly different way from how software did, but it's a similar idea.”

[1:44] ML: “This race to green, zero carbon steel is a really big deal. Cleaning up the steel industry would mean that we could cut global carbon pollution by 8%. That's more than the total greenhouse gas emissions from India. And some steel companies are betting big that hydrogen will be the one to pull it off.”

[0:36] “What Recoolit is doing is partnering with AC technicians around the world to collect those harmful refrigerants, preventing them from being leaked into the atmosphere, and then destroying them and selling carbon offsets for the avoided emissions. So we are the software layer in that process that goes from the source device that's being decommissioned into the hands of the AC technician, into a cylinder, into a big oven to burn it up. And then the data goes to the offset buyer.”

[1:02:33] “I always tell my team that if our technology is the only one that wins, we failed, because we're not enough to change our climate trajectory. […] We say we're trying to create carbon smart consumers. I do believe that consumers have a role to play. And if I can get a party dress made from recycled carbon, that's going to be 10, 20, 30 people talking about that party dress and talking about carbon, talking about why climate change is important, talking about the fact that everything we use comes from fossil carbon, and saying we're going to have to do something.”

[4:30] “Rubi focuses on decarbonizing supply chains focused first on fashion. We turn carbon emissions into carbon negative materials using a technology we've developed that's inspired by how trees work. So trees breathe in CO2, and then they turn that CO2 into all their useful components and molecules. We take a similar approach where we're able to take CO2 and turn it into all the important molecules we use as a society for our most important products, like cellulose, which we use for textiles. That's really our first chapter is making textiles that are carbon negative and water and land neutral using a completely new production process.”

[19:01] BK: “Proof of work is essentially a race for everyone who is running to try to capture the flag. […] It uses a ton of energy. […] And only one person ends up capturing the flag. Proof of stake is a lot different. Everyone lines up at the starting line to go capture the flag. But instead of everyone making it run, a random person at the end sort of spins around three times and then points at someone and says, you go do it, and only one person goes to get the flag. So we've just saved a ton of energy. […] It's like all these computers stand there and they're ready to go help mint that block on the blockchain. But instead of all of them trying to do it at once, […] the person that actually does is randomly chosen and so that cuts down the waste of energy. […] It's literally a 98% reduction.”

[8:38] “In terms of the motivations, I think the strongest ones on a global level are certainly the climate and environmental benefits. We're looking at basically 20% of contribution to global greenhouse gasses coming from the livestock sector. […] There's also really substantial public health benefits associated with moving away from animal agriculture. A recent UN Environment report titled […] “Preventing the next pandemic” identified intensive livestock agriculture and growing demand for animal protein as two of the seven biggest drivers for risks of zoonotic diseases, which are viruses or other infections that emerge in animals and then make their way into human populations. […] And then I think there's a lot to be said from a strict market efficiency and resiliency and food security perspective.”

[2:10] “We're in a crisis. […] Over the last 20 years, the river has lost about 20% of its flow […] and I think a lot of climate projections are suggesting that we could lose an additional 10 to 20% more of the water available in the river. And we're at this key point right now, reservoir levels are dropping precipitously both in Lake Mead and Lake Powell, runoff is not what […] historically has been. Just very simply, we don't have the river that we used to have.”

[18:45] “I think the root cause for the slow uptake of more reuse, even in places where they're experiencing pretty acute scarcity and it just makes all the sense in the world, is that water tariffs tend to be very low. I think it's $2.58 per cubic meter of water […]. So it's basically just just under a penny per gallon of water treated, delivered to your home. So water tends to be so inexpensive, that when businesses and even communities look at reusing wastewater, they just can't make the economics work.”
