I really cannot see the appeal of these fans.

If you need a fan to distribute heat, then you can buy an electrical fan of similar size for about £10 and the running costs are minimal - about 5 hours for 0ne pence.

Also you can use the fan in the hot weather like today.

I got one for my olds for Christmas and tbh its not gimmick - they do work and do a bloody good job.

The olds have a wee Stanley in quite a small opening, the eco fan just about fits and works away silently.

Its not so much the cost of running an electric fan - but the noise and cable running across the floor

Anyways they have one now and as my mum says, the room is a lot more pleasant to sit in, a lot warmer without having to keep the stove at full pelt all day which becomes too much

I got one last winter and was very pleased with it, it blows the heat down to the bottom of our living room which before didn't get the benefit of the fire!

We have 2 one on each stove. They are very very effective.

Thermocouple effect can generate that much electricity?
I suspect it's the air current that's driving the blade.
I'm fairly sure I have seen a medieval rotisserie driven by rising hot air, in the manner of those carousels turning by candle heat.
So if somebody has a paper windmill could try it out,
it will probably spin without electricity.

This idea could be extended to the Myson Kickspace type plinth heaters, which have an electric fan blowing on a radiator.
It's a pain to have to arrange an electricity supply,
so they (Myson, Smiths Environment) should bring out a turbine powered version, so the primary flow drives the fan. I know the pump still consumes electricity so it's not free energy, but it's easier to install, and no electricity gets near a leaking radiator.

They are not driven by air currents. They use peltier cells to produce an electrical current. This then drives a small electrical motor & fan. (google seabrooke effect).

There are stove fans which use the stirling engine principle and are very good. I have one of these and it performs very well although they are expensive. Google Vulcan stove fans for more information.
