Hey People, I hope one of you can help.
I need a way to generate current (low voltage) from a fairly constant heat source. Probably need about 3 watts. The heat will be around 200 degrees F., maybe hotter, but always fairly constant. I've been told about, and have done some reading, on thermocouples and, I understand that many thermocouples, are called a thermopyile (pile?), but, my problem is that I can't find anything that generates anything more in output than milliamps, like, 20. (I'm not stuck on thermocouple technology either.)
Can anyone help? I'd be VERY appreciative. p.s. (don't say steam...thnx)
