There's certainly no shortage or researchers and companies promising to bring fuel cells into everyday gadgets, but Ronald Besser of the Stevens Institute of Technology seems to think he has a system that can stand out from that pack. According to MIT's Technology Review, Besser's proposed system consists of a cylindrical design with "combustor" at the center that facilitates all the necessary reactions to convert methanol into hydrogen. Apparently, that design not only allows for the fuel cells to be made smaller, but more efficient as well. While it seems to still just be on the drawing board, Besser says the system could eventually allow for laptops to run for upwards of 50 hours, and could be made small enough to power other portable electronics as well. In the meantime, however, you may want to keep an eye on some of the systems a littler closer to reality.
