Thought someone might find this interesting - a step up DC DC converter that works from 20mV up.

Time flies when you have a bad prescaler selected.

Has been mentioned before in a topic recently:) but indeed very interesting, though I cannot think of an application for it yet, personally.

LT always has nice ICs, though a bit expensive :(

"The LTC3108 is a highly integrated DC/DC converter ideal for harvesting and managing surplus energy from extremely low input voltage sources such as TEGs (thermoelectric generators), thermopiles and small solar cells. The step-up topology operates from input voltages as low as 20mV."

Perhaps you might make a converter for using a water heater thermocouple, stick it in the camping lantern and generate power to charge a cell phone or run something else?

Well, that's the idea. Amongst other advised usage is, say, a remote control recharged by the users body heat.

Harvest ambiant RF noise anyone?

How about harvesting ambient Freak noise :)

Actually, for me, that is a very interesting chip. They have also just announced a companion chip for converting from very high impedance sources such as piezo devices.

During last meeting with LT guys, they showed energy harvesting demoboard which uses piezo to charge battery and lit up LED. Place it on a crowded sidewalk and you will have source of free energy :)

Actually, they did stuff like this already: http://www.dself.dsl.pipex.com/M... (scroll down to the end section). Apparently, it was popular in Soviet Russia.

This just begs for a "In Soviet Russia..." joke.

Thermoelectric generators have been used in rural Soviet Union/Russia since at least the 1940s. I remember seeing pictures of kerosene lamps with a thermo generator built into the the top of the lamp. They were used to run small radio receivers, among other things.

Russia is scattered with Radioisotope thermoelectric generators to power light houses and navigation beacons.
