New development on the liquid-powered battery front. Samsung’s apparently "developed a micro-fuel cell and hydrogen generator that runs on H20."
Metal and water inside the phone bump uglies to produce hydrogen, which is supplied to a small fuel cell where it bumps uglies with oxygen. After all is said and done, you’ve got about three watts of power. That’s enough for about 10 hours of use. Not too shabby, eh?
One snag. There’ll be a hydrogen cartridge that has to be replaced every so often (about five days if you use the phone four hours a day). Later efforts will likely not require replaceable cartridges, though.
