This should prove interesting, since one of my last two laptops had a poorly designed power cord which resulted in a small explosion. My more recent one, a Compaq, was actually recalled for exploding power supplies. I can see it now -- one slight leak and BOOM -- flash fire!

Same thing happened to my laptop. They said there is something wrong with the motherboard. Now, I have to change the battery every few hours. What was your solution?

a. Fuel would likely need to be purchased like lighter fluid. Ubiquitous, and nonflammable Electrical power is available for free at airports and train stations (even onboard trains) supermarkets, shopping malls. makes these fuel cells nothing more than a novelty.

b. It would have trouble making it through an airline checkpoint. Imagine trying to explain the principles of fuel cell technology to Hamid Islam at the airport security checkpoint.

This is a non-starter.
