Joule Thief

I've been looking for an ultra low forward voltage drop diode to use for a little project I've been working on (in my head) and so far, the best candidate is probably a mosfet-- DS junction. doing design work in your head eventually needs practical (working) designs to give motivation, check out this Joule Thief circuit to steal the last bit of juice from your battery, down to about 0.35V to power an LED. pretty snazzy huh? you can see if hooked up to a Peltier (called a seebeck when used as a source) at instructables. I miss the days of having the time to actually do fun stuff. we have alot of these TEC (thermo electric cooler) junctions at work, so I'm going to start harvesting out of scrap units for projects at home.
