how do i make a portable ac electric generator?
i once saw a guy walk onto a charter bus with a heavy box that was home made with electrical outlets. it was about the size of a car battery, maybe a little bigger. he plugged his laptop and things into it and used it as if it generated 120W. it was quiet and didn't have a running motor like a generator. does anyone know how this was made or what it was composed of? i want to make one like it , or that does a similar task. i want to be able to charge my laptop on a long trip.

I just saw an article about them. It is a fuel cell run from a butane cartridge. If I can find the article, I'll send you more info.
