Did they have enough tech by that point to even begin to figure out mass manufacturing of solar cells to focus enough energy into water to make steam? Burning something that burns well is a much more intuitive and scalable process...
Also, mining the easy stocks (at that point) is a low tech affair too. Which was powered by... combustion of fuel and human labor.
We still can’t make solar panels with 100% efficiency, what hope did they have?
- windows_tips 8y agoYou don't need solar cells to heat water to boiling, just glass or a metal like aluminum or silver. With glass you can build a lens to concentrate light. With a metal you can build a concentrating mirror.
- codeisawesome 8y agoGood points. But lens building is a complex endeavour that requires tooling at the manufacturing level (especially computing power!) - no matter the choice of available material, yes? Doing it with high precision at a civilisation-powering scale seems like an impossible ask of a species that was still considering much of their Home planet to be “new” (Americas).
- windows_tips 8y agoGalileo was making lenses hundreds of years before the time we are talking about. Also, eye and magnifying glasses existed then.
