Re Besoeker's last post :-

I noticed that the commentator said 'a small electric 'motor' whereas to me it looked a very big electric motor.

I think the basic principle that this works on is conversion of manual work to heat. I seem to remember that some wind turbines worked on a similar principle - heating up an oil by turbulent mixing (viscous drag causing frictional heating) and then to a heat exchanger to heat the house or whatever.

Have you any follow up to this ? Has he, or anybody competent, measured energy in versus energy out ?
