Concrete and carbon sequestration 

The bottom line? We鈥檙e inching closer toward an uninhabitable planet of our own making 鈥斅爀ven faster than once thought. To get ourselves back on track, we need to continue curbing our emissions to avoid making the problem worse. At the same time, we鈥檒l need to remove a trillion tons of CO2 from the atmosphere, says Peter Fiekowsky, Founder of the Foundation for Climate Restoration.

Concrete and carbon sequestration 

@solarpunkgnome This gets me really excited, of course this is no silver bullet, but knowing that there's an alternative to current carbon emitting concrete that actually sequesters it instead is incredible.

Concrete and carbon sequestration 

@solarpunkgnome This is the kind of stuff that keeps me hopeful. These are the kinds of technology we need to be developing.

@starwall @solarpunkgnome this sure does sound great. but coming from Los Gatos, home of some of the finest multi-million dollar techbro mansions in the whole Bay Area, well, i'm suspicious.

Concrete and carbon sequestration 

@t54r4n1 @solarpunkgnome millionaires or not we really need viable, affordable, and mainstream carbon scrubbing and sequestration tech and this is really promising. Ultimately I'd like for the process to be reverse engineered and made public knowledge rather than patented but for now I'm just happy this process exists and is being scaled up.

@solarpunkgnome I wonder how well this would pair with the volcanic ash + seawater Roman cement recipe that was rediscovered a while back? That's more energy-efficient than Portland cement, so coupled with a carbon-sequestering aggregate there could be some really good numbers there. Ecologically ethical brutalism, here we come!

Volcanic ash makes for wonderfully fertile soil, let's not make buildings out of it.

@anne @lordofthesquids
I imagine there are a lot of other compounds that would work for the cement bit, but my background is more in electronic than structural ceramics.馃し

Concrete and carbon sequestration 

@solarpunkgnome I'm actually working in a concrete research lab this summer, so I'll see what I can do to find out more about this. The lab's current focus is thermoelectric concrete, which would improve energy efficiency for building heating and cooling, but if the three techniques could all be combined somehow, the resulting material would be amazing!

@lordofthesquids I did some research in materials back in the day. What compositions are you looking into, if I may ask?

Concrete and carbon sequestration 

@solarpunkgnome I honestly don't know yet. When I applied to the program, I tried doing some background research, but there's not too much published yet. As far as I understand it, there are some compounds you can mix into the concrete to turn the entire body of it into a thermoelectric material. No clue what those materials are yet, though. I should know more in a few weeks (unless it turns out this is all supposed to be under NDA or something).

@project1enigma It was a different method, but I remember one of my professors complaining he accidentally made coal when doing a synthesis back ~2007. I think he said it was easy to do, but since there was no market for expensive, artificial coal, I don't think he wrote it up. 馃し
