This is a fascinating project but I’m always frustrated when they don’t share the formulation of their materials. Looks like a lot of reinforcement. A major downside to modular geodesic construction is the number of seams that invite leakage over time. A more monolithic application of a slower-setting material over a frame would be preferable to me.

Having experimented with a lot of concrete composites I’m always looking for the sweet spots of frugality, obtainablity, practically. This appears to be some geopolymer or magnesium cement -fairly exotic materials for me. Geopolymers often require a strong alkali to set. Not a huge fan of Portland, but at least it’s obtainable and relatively inexpensive for sustainable use cases.

And I’m cracking up at the scammers phoning up my 85 year old father telling him his Windows has been compromised on his Linux desktop.

Whoa. “Going to Hell in a handbasket” just got literal.
