I was involve in trying to prove https://en.wikipedia.org/wiki/Autoclaved_aerated_concrete https://en.wikipedia.org/wiki/Autoclaved_aerated_concrete a viable alternate to concrete and red brick frequently used in household development. The only part I was unable to secure was seed capital. Does anyone know of program which invest in green/climate fighting `hard` start ups? Love to get in touch with them and revive my project.

- Gibbon1 7y agoI think AAC is an increasingly common building material outside the US. I think it's being regulated out of existence in Europe because because AAC only has moderate R values it can't meet passive house rules. R value of 15 or so vs the 30 or more required by passive house. Which is insane. Passive house assumes the house is going to be heated with fuel oil or nat gas it's whole life. And it's obvious that isn't going to be case over newer houses 100-200 year working life. Dirty secret about solar and wind is the supply isn't constrained like oil and nat gas. So designing houses around energy scarcity is 'dumb'. And building houses to use nat gas/fuel oil even dumber.
