Also we should be moving away from concrete as a building material where possible because it's terribly energy intensive to make. Of course we need it for some things but there are better materials for walls in normal residential buildings.
Bruh it takes a mixer and water. The only thing that would get used more than not, is water.
Lumber is stupid expensive, brick homes are labor intensive and more expensive, you can do mixed substrate homes but that's expensive too. Glass paneling is usually only for stupid rich people or businesses and metal siding with metal interior and a metal roof, you may as well live in a shipping container.
The energy intensive part is in creating the dry mix. ~~Mostly in creating the lime.~~
Edit: Here's the breakdown for anyone interested.
And electricity is carbon neutral because it comes out of the power outlet.
Muh Cynicism: Well once the billionaires charge us a larger premium for nuclear energy maybe science will invent magic, har har har.
Nahhhh but to be honest no one can be happy with anything when it comes to energy: Hydroelectric, the fish. Solar, the agricultural and livestock. Nuclear, land and ocean contamination that can last as long as the US has been around.
3D printing houses that can solve a housing crisis, the process it takes to make the concrete.
Can't we just shut up and and enjoy scientific advances.
I agree. We should work on 3d printing wood. Stick houses are superior
Like chip wood into strands, mix with glue and print it out like one big shape of plywood?
