Has anyone else seen this? It sounds interesting, but expensive. www.thepowerpot.com/How The PowerPot Works To use the PowerPot® all you need are a source of cooking heat, water, and a USB device you want to power. With water in the pot place it on a stove and you will start generating power right away. The temperature difference between the bottom side of the PowerPot generator system (on the heat) and the inside of the pot (holding water) is harnessed to create electricity by utilizing the phenomena known as thermoelectric power (TEP) The PowerPot thermoelectric generator works by transforming some of the energy going from the flame into the water into electrical power Our voltage regulators are designed to safely power USB devices from the raw output of the PowerPot They go on (on the website) to give some background on thermoelectrics.

Took the liberty of embeding the video for you and making it easier for other members. I like the idea...pretty cool. Thanks for sharing. Hopefully some other member has actually tried it out

Idea has been around a very,very long time. Nothing wrong with it as long as you are burning fuel for another reason already. The cycle is inherently very low efficiency in terms of energy in to energy out and best applied to waste heat applications.
The real power output is between 5 and 10 watts per hour. Someone buying one of these needs to understand what that means, because it's a small amount of power in today's power hungry world of electronics.
Like anything else, it's all about fully understanding what you are getting for your hard earned dollars.

Thanks for embeding the video, Orly. Marc, I agree that it is inefficient. But it is a way to get electricity out of a wood fire. I am interested in getting one of these, but I was wanting to see if our friends had any first hand knowledge of them. One of my buddies at work sent me the link below on how to charge your cell phone with an onion and gatorade. www.youtube.com/watch?v=GfPJeDssBOM

Go for it and let us know what you think!

I have been thinking of buying a Biolite to test it out but at $130 its a bit steep for a single youtube video moment.

Marc has the right of it on this one. The Seebeck effect is very low on efficiency (at least for now). Where heat is produced anyway (waste heat), it may as well be used rather than let go totally to waste. On the other hand, it's a rather large waste of energy if it's used as a primary charging means. That said, it can be combined with solar concentration of heat and cooling water to increase output. Some food for thought.

wow, I am glad you found that. I like that better than the pot.

This guy does a couple reviews on it. Bear with him when it comes to speach, hes a vet with some neuro problems that affect it.

thanks for posting the review. I don't like that you have to charge up the stove prior to taking it out. I think I might go with the pot instead.

From Biolite:
You dont have to charge it first, but its a good idea. Just like when you get a new phone or some thing the company asks you to fully charge it before using it.

OK. Gotcha. I didn't catch that.

It was burried in the FAQ on another page. When I first read what you wrote it totally turned me off, I had to reassure my self because I think this stove is awesome.

Let us know how it works for you, and if you think that is worth the money in a real world test!
