Thanks! Yea it started as a bit of an anger management project. I am the absolute worst version of myself when forced to endure customer service calls. 1. The user (you) needs to p…

I absolutely hate being forced to make a phone call. It’s a 1970s solution for 2026. When something goes wrong with a subscription, delivery, or account, the only remaining option …

Awesome, impactful concept, this can be huge! Now comes the challenge of scaling

Yep, absolutely right! Combining our product with something like the carbon curing tech of Solidia or CarbonCure would make a net-negative concrete. I don't consider us competitors…

Same idea for iron!

Agreed!

Impressive analysis! Missed out on a couple details, but I'll take that as a thoroughly researched/analyzed endorsement. Most importantly, we'll be scaling up a lot faster. Our cur…

Absolutely! This is a big part of our thinking for how this integrates with future energy systems based on renewables. We'd offtake cheap electricity when oversupplied, like in Cal…

Our process produces calcium carbonate, CaCO3, which cement producers can then burn to make quicklime, CaO. This does release CO2 but that CO2 has been captured from the atmosphere…

Yeah absolutely, the CO2 balance comes from re-equilibration with the atmosphere. The rivers replenish calcium content on a longer time scale. But as you point out we're in no dang…

We make CaCO3, I mention CaO here because that's what cement producers ultimately need. They heat up limestone (CaCO3) to make CaO

All 'waste' we produce we either consume in our process or we're able to sell as a commercial product! Not bad tackling ocean acidifcation to boot

The ocean is 20x supersaturated with calcium and is constantly being replenished by geological stores of the stuff coming in through rivers. As long as the ecosystem remains supers…

Convenient that ;)

Absolutely, CO2 emissions from transport isn't much of an issue compared with the saving. Hopefully someone like Remora will crack that problem anyhow. We'll most likely need to bu…

Thanks! ABsolutely, looking at optimizing time of day we operate will be important. As grids become more dominated by renewables a solution like ours will be able to help stabilize…

Yep! It'll be quite a journey to get there

That's actually the trickiest part of the engineering, but we've managed to make it directly compatible with the an intermittent energy source like solar and wind

Will DM you

That's part of the CO2 saturation of the ocean. So when we remove that dissolved CO2 that equivalent amount is removed from the atmosphere

So true, it's a surprising statistic to most that 8% of global emissions is actually from concrete

Love the enthusiasm to share! This is a bit of a coming out party for us, so not much out there in the way of public information. We'll add to that as it comes higher on the list o…

We actually use concentrated brine in our solution!

Some exciting innovations in this field in terms of using white paints to reflect away light and reduce surface temperatures!

Thanks, will keep you in mind! Watch out for posts on Work at a Start-up for when we expand our team in the next few months
