Nothing new under the sun

Someone posted this before and I still think it's about a useful as a pedal powered wheel chair.

So do I. But I also like checking out new gadgets and ideas
PS. You know what the worst thing about wheel chair is? People talking behind your back and pushing you around...

The idea is really good but the actual amount of converted energy you'll get is practically pointless. Same as with all these bioLite things. What I said before 50,000mah power bank and my 240g cookset. Job done.

What I want is a bit of metal on the end of a wire you can throw into an open fire and has a USB charging port on tother end.
With base camp fires running for hours sometimes it must be possible to harness some of the lost energy.

Problem is with both of these ideas you need a heat sink to relief the plate from over loading hence why it's attached to a container of water.

Skeptical about all these small devices, and still requires water for to create the temperature difference.
When I go to the woods I turn off all my electrical stuff - I go to the woods to get away from all that stuff!
On exped it could be useful I guess but I found that 4-6 AA batteries for torches and camera plus two mobile phone batteries charged before going would last me about a month.
For longer periods or higher demand on batteries I have used a solar panel for recharging ... but that let me down when I most needed it!

It means I agree
Which is why you should consider a USB power bank instead
I have a 240g cookset and a 50,000mah power bank. Jobs a good one.

I've got a boxed mamod steam engine from my dad and I tell you what it doesn't half go.

Don't know if it still works because the last time it was chugging away I was about 11 but I should imagine it would go first time. I'm going to try it now lol.

The technology behind the bio-lite stove and similiar devices like this has been around for some time but in the last five years manufacturing advances have significantly brought down the price of Peltier Modules. FYI they also come in wide range of output voltages so you're not limited to charging USB kit but 12v is posibble as well and like batteries can be stacked in series or parrallel configurations to provide the desired voltage or current required.
IMPORTANT: when connecting a peltier device to sensative electronics such as cell-phone or other USB charged device you will need to wire in a five volt, one amp fixed voltage regulator, these only cost £2 or so and will stop any expensive kit going bang.

Other devices that may be of interest are Stirling engines and the less well known about Nitinol wire that can use heat to turn a dynamo.
