Futurology

Yeah a friend told me something like that but he forgot to compute how much energy is needed for silicon and how much for titanium. Like aluminium is one of the most used materials but it still is a massive use of energy to refine it from bauxite or what-you-have.

Don't know, I'd say the mainstream is trying to go grapheme and or silicon and these dudes are trying different stuff for the sake of doing it differently.
