It's known that hydrogen burns in ultraviolet
range of spectrum.If I no make mistake the
more energetic photons we have the greater
efficiency photocells could have.And also it's
easier to make photocells which are designed
for some narrow range of spectrum.
What prevents to create and use highly efficient ultraviolet photocells which work from
burning hydrogen or gasoline?Maybe it's cheaper than fuel cells?And what about gasoline,in what range of spectrum will it burn?There's plenty of hydrogen atoms.
