Fuel Cells for Laptop Computers 266
ArbiterOne writes "An article in PC World states that the company MTI Micro Fuel Cells plans to demonstrate a new technology this week that could pave the way for better power technology for laptop and palmtop computers. The article claims that this new technology could provide a battery life 2.5 times greater than that of a lithium-ion battery. Could this be the solution to the problem of short battery life in high-end notebooks?"

I can see enjoying the option of one of these long life power units if I'm on a flight or in some environment where I need that much portable power without the opportunity to recharge, but it seems doubtful that fuel cells are going to make a major impact on portable electronics until the infrastructure solution is solved. Even still, the infrastructure exists for non-rechargable batteries, yet many people prefer devices that have modern rechargables - it just makes more sense for most situations.

"Disposable" fuel cells have to be compared against primary batteries, not rechargeable ones. Rechargable batteries typically have about half the energy density of primary batteries. So claiming a 2.5x improvement in battery life for a nonrechargeable system is not a win.
Ballard [ballard.com] is further along than anybody else in larger fuel cells. Even they don't have much more than prototypes. Their attempt to market a fuel cell under the Coleman brand was a failure [businesswire.com]. The Coleman Powermate was launched with great fanfare in 2002, and never shipped. It's not clear what's wrong at Ballard. Their 1KW units should be providing backup power for cell phone sites and such, but it isn't happening.
Ballard uses hydrogen in their fuel cells. Despite all the hype about the "hydrogen economy", Praxair, which sells hydrogen for fuel cells, has this to say:
Fuel cell grade hydrogen is specifically designed to be used as a fuel in fuel cell applications. It contains extremely low levels of impurities (e.g. ammonia (NH3), carbon monoxide (CO) and sulfur compounds) that can harm the catalyst-coated membranes inside the fuel cell.
It is supplied in high-pressure cylinders and can only be used by industrial customers, like factories, laboratories, universities, and military and government installations. Typically, industrial customers already use compressed gases as part of their daily activities. Its use requires adequate ventilation and/or monitoring systems appropriate to the size of the location, helping ensure the safety of personnel when non-air gases are present.

1) Unlike plutonium, U-235 is not radioactive enough to be used as a heat source for a thermoelectric generator.
2) A small pellet of U-235 cannot generate electricity via nuclear processes. You need a critical mass in order to sustain fission, which is a minimum of around 15 kg in the case of U-235.
3) Nuclear reactors are really just steam-driven turbines which use nuclear fission as the heat source. You could generate power just as easily by lighting a big fire and using it to boil water (and in fact that's exactly what fossil fuel plants do). Obviously, this isn't something that can be scaled down to portable sizes.
4) You don't need anything approaching 20 pounds of lead to shield you from uranium's radioactivity. You wouldn't want to swallow it, but you could hold a bare pellet of U-235 in your hand perfectly safely, and a paper-thin layer of lead would completely block its radioactivity. The massive shielding around nuclear powerplants is primarily there to protect us from the neutrons generated during fission, which are very difficult to stop.

Now, we've built thousands of transmission towers. Why not tap into some of that power? Sure, you can't run a laptop on the power off one 900MHz antenna, but what if you had, say 500 of them in a little bundle? Even then, if you couldn't run the laptop off it, you could use the little power you did get to trickle charge the battery - making it last a lot longer.
Before you get freaky ideas of humping around 500 antennas on your back, take note that an effective 900MHz antenna can be as little as half and inch long. If you arrange them like spokes on a wheel, you would have a 1-inch wide disk. Now, the trick is to fit the electronics to convert the AC signal into the same small package.
