MIT engineers designed a system that can efficiently harness the sun's heat to split water and generate hydrogen. The goal is to produce green, carbon-free hydrogen fuel with a train-like system of reactors driven solely by the sun.…

Hydrogen, whose only byproduct is water, has to be produced from other energy sources: natural gas, nuclear, biomass, solar, or wind power. It isn’t yet a practical source of energy, because 95% of all hydrogen is currently produced from…
