Centrifugal forces and heating
Centrifugal forces and heating
(OP)
Hi,
I would like to know why this mechanical machine can't works ? The idea is to recover energy from one source of heating with help from centrifugal forces. At 20°C the mean speed is around 500 m/s and this say the machine must turn at least at 5000 r/min with a radius of 1 meter, it's possible to think with bigger radius for have shape of cylinder/valve like drawing. On drawing I zoom+ the cylinder for detail how gas are in it. The valve turn only at 5000 r/min, it's the cylinder that recover energy from heating when it translating. Cylinder turn like valve at 5000 r/min but sometimes it turn around the axis of valve for repeat cycle. The gas last/win energy from rotating but in a complete cycle the gas win/lost nothing from centrifugal forces, it's possible to imagine gas without temperature, this system can't win/lost energy or maybe from friction. I'm sure this need calculations but maybe you can see where this system can't works ?
Thanks
Regards

Anyway I think the point is that to turn the cylinder around x axis you must spend energy (work) as you need to overcome the centrifugal force displacing the cylinder to a shorter radius, and I guess (didn't think of this in depth) that this work is equivalent to the energy spent to compress the gas (plus of course the losses due to gas heating). So no net energy output, but only consumed energy.
