small battery
If you get a Peltier cooler, and heat one side while applying a flow of air to a heatsink on the other side, it will put out low DC voltage at high-ish current. Into the right kind of load. So, that'll work from any battery that can heat a resistor and maybe run a coolling fan. Well, you DID say 'any thoughts'. Seriously, do you have any accuracy requirements? AC or DC? Any preference on battery type (palletload of lead/acid, or single hearing aid cell)? Duty cycle? Battery life under load? |
