well here it is :
the BioLite stove , power from fire..
This is most likely the stove you don't want and almost certainly the one you don't need, nevertheless it is an interesting product.
(for me...)
Just received this today after it was sent to a Californian address early last week so to use a cliche hot off the press...
So far as a stove it works very well indeed , as a USB power supply not at all but very possibly my fault..
(I will need to do some more tests...)
Here is the video:
