#82Looks great, good luck! Question about the seawater aspect, are ecological impacts similar to conventional desalination processes?

#83Sounds promising! I have noticed companies with environmental impact have disproportionately more success in crowd-funding.

#84Curious about the name, my immediate thought (and interest making me click in) was that it sounds Norwegian. Any connection? I really like the idea. One thing I'm curious about is what's in it for the contractors (edit: cement producers) buying from you instead of others? I get the environmental impact, but my guess is they only care if touches their bottom line. Will it be cheaper, either in raw price or because of…

#85Just curious: at what point does concrete release C02? In a particular part of the manufacturing process? Or throughout the process?
