I know someone, somewhere posted up the original one of these.
Here is the first homemade one i have seen

Very cool, thanks, so many clever posts at instructables. Is this the post you meant?

Yup, the Biolite.

There is another company doing the fan powered mini stove/forge, but they dont have a peltier chip and buck converter attached.

the Sierra Zip Stove, been around nearly 20 years now.

Steve Harris has a new one as well. Looks to compete directly with the Biolite. Nopub publications or something like that.
He has changed up the rocket stove a bit, taking in air from beneath the fire & using a square firebox.

I think these type devices will continue to improve. To date, no one I know of has combined the big 50 Watt modules with a rocket mass heater. During winter months, when the cold outside can chill an antifreeze coolant used for the cold side, that setup could kick butt. During summer months when the RMH is not used, not so much butt kicking, though.

Look no battery!
