Magnetohydrodynamic methods
can generate electricity through natural ionization in plain-old water. At the
level of the micro-channel, you do not even need to "split" the water. This kind
of process should make Fred Sparber happy, as he has mentioned that the
"natural" ionization of H2O should be amenable to use on
several occasions.
Also it vaguely similar to the way an
"ultraconductor" works, if I am not mistaken.
BTW, If you want to get attention these days, just
throw the prefix "nano" in there, even where it doesn't belong. These guys
resisted the urge, even though they could have gotten away with it, as arguably
to get from the 1% eff. to a level higher, one is going to need to go
smaller:
The prototype battery generated 10 volts, and
presumably it requires pressurization, but that should be "free" from solar
energy.
