local sustainable bldg materials and methods?

We could make our own solar cells from "Hawaiian regolith"... https://www.freethink.com/space/solar-ce...r-regolith

Also, if we're making our own cells, we could design them to overlap like shingles or ceramic roof tile, so the panels could *be* the roof.
