The device actually makes electricity !.
That might not sound like a lot but in the land of the blind the one eyed man is king. If you happen to be on a deep space mission & have 7 Watts instead of zero watts you would be a very happy person.
Similarly, for the 'prepper' community, 7 Watts, 24 hours a day from any heat source will be very useful.
But 7 Watts is just the start. This was the first trial run with a basic magnetic assembly. The displacement is small at about 2mm. We are looking at ways to multiply this by orders or magnitude.
We have a friend who happens to have a suitable solar collector. We are now just waiting for some decent sunny weather to see how the solar version works.
I think this has definite commercial possibilities. Once you know how, it is easy to make. It is entirely maintenance free. There is no doubt that it will eventually make a lot more than 7 Watts. It would even make an excellent executive toy..
Noise is something of an issue but we can solve that with a clever casing..
This particular project is badly written up but I will fix that (in the very distant future). This device is beyond cool. Shocking that NASA gave up on it. The potential is huge.
