It uses soil, without firing it sounds like they’re just expensive mud huts?
Better than nothing!
This is the UN, remember. They aren’t worried about people with options. The question is if this thing is actually easier and cheaper than local labour.
Another good point- lets fix poverty by replacing local labor with a 3d printing machine!
I’m no luddite, if it makes sense to automate some menial task we should. Let’s do the napkin math.
It says it costs 180,000USD. A labourer in rural Columbia might cost 1USD per man-hour. If we assume it replaces two workers, and produces a house generously 3 times as good, that’s your investment back in 30,000 hours, or ~3.5 years.
Actually, that’s decent. I guess I was expecting it to cost millions. If you make less generous assumptions, you get a less generous result, but they have a shot.
