Cheap solar water-splitting

[Brian H]

Not a fusion process, of course, but possibly competitive. ARPA-E winner process:

Break up the water while the sun shines, then recombine in a fuel cell when it doesn’t. Uses phosphorus and cobalt.

Its fusion, just the sun kind 😉
Still this is probably just the catalyst in the electrolyzer, nothing to do with solar cells themselves.

Fusion WILL be the way … simply because it is so incredibly dense source of energy.
The rest is engineering … and engineers are pretty good once the dollars are in place …
