A better solar-powered water splitter

Metals are just ceramic wanna-be's.

It's something that summarizes so much chemistry, so much material science understanding, and so many problems that we run into with using metals - and apparently with metalloids (semi-metals if you're British).

I'd never thought of the problem of corrosion with metalloids, though it's understandable that even metalloids would 'want' to react with oxygen since all metals do, too.
