I've had an idea at the back of my mind for a while now and just stumbled across this site which looks like the ideal place for a project like this.
The idea is to build a generator capable of supplying enough power to run a laptop or other small devices while out camping. It would need to be able to produce about 120 Watts of power (1/6 horse power) and run for many hours at a time. Making it run as quietly as possible would be a bonus as most campgrounds have rules against running noisy generators. I can build the electronic side of things easily enough, but am not sure what to use for the engine.
A steam or Stirling engine running off a gas cooker or BBQ could work. Or perhaps a small engine using petrol. I only have occasional access to a lathe so the more simple the better. Any suggestions on what engine to use and where to get the plans?
