Fuel-Cell Power With Methanol
foaty writes: "It has been reported that Japanese electronics companies have developed prototypes for fuel-cell batteries that can power the smallest of electronic devices for long periods of time, and they only need refueling, not recharging! See the article at FutureEnergies.com." That article links to this piece at ZDNet; what's interesting is that instead of hydrogen, this article talks instead mostly about methanol-based fuel cells.
I for one prefer a nice safe, Ni-Cad or Lithium-Hydride battery, but then I'm pretty health conscious.
