Sounds good....better than centrifuges for Iran.
as the Hindenburg disaster demonstrated, hydrogen is also the most difficult element to compress into a safe, usable formThe Hindenburg's hydrogen gas was merely contained in a number of lift cells, not "compressed"; the hydrogen that burned during the Lakehurst disaster was leaked out of a leaky cell, beginning a few minutes before docking maneuvers began, and when ignited (and there's no firm concensus on how that happened), burning holes in the other cells, which ignited the rest of the hydrogen in the cells.
Rich Diver, inventor of the Counter Rotating Ring Receiver Reactor Recuperator (CR5)... claims that his solar-powered reactor could help clean up the planet by making internal combustion a reversible process... Right now, it's cheaper to drill for oil and refine it, according to Diver; but in 20 years, as oil grows scarcer, synthesizing fuels for traditional gasoline and diesel engines will become an increasingly attractive alternative... Diver's invention, the CR5, is essentially a stack of counter-rotating rings coated with iron oxide (rust) along their edges. The top ring in the stack is exposed to direct sunlight to supply the necessary heat to power the fuel generator. Inside the reactor, the levels of iron oxide are diminished as some of their oxygen atoms are removed. At the other end of the stack of counter-rotating rings, water is introduced in the form of steam. The iron grabs oxygen from the steam, thereby re-oxidizing the iron oxide (which is conserved throughout the reaction) and leaving behind pure hydrogen... The traditional method of making hydrogen from water uses electrolysis, but Diver claims his technique offers greater than 20 percent higher efficiency because it "eliminates the step of making electricity from solar energy." ...carbon dioxide would be collected from coal-burning plants and recycled by the CR5 to produce synthetic fuels able to power conventional automobile and truck engines, making vehicle powering a renewable process that does not further pollute the planet. However, even if all steps come off without a hitch, 15 to 20 years are needed before the CR5 can be put into widespread use in creating synthetic fuels, according to Sandia.Iron oxide has also been used to improve the efficiency of the competing technology, water electrolysis to produce gaseous hydrogen / oxygen.
