Re: [EVGRAY] An old idea

Body

The COP increases with less differential temperature between the cold and hot side of the heat pump.

With the outside air temperatures that Warren mentions the inside temperature must be quite low to get the high COP. Heating all the floor keeps the hot side at a lower temperature but with down to -30 degrees Celsius and perhaps +30 degrees Celsius on the floor this amounts to 60 degrees C or K in difference. I doubt the COP is high at these extremes. Perhaps it's still better than pure resistance heating.

 James, Heat pumping works due to thermal differentials. Believe it or not but Industrial MVR (Mechanical Vapor Re-compression) has achieved a fantastic 40:1 COP. Domestic Heat Pumps run around a COP of 6:1. (scroll compressors).  See:

 I've heard of people using a deep well like 350 ft down for heat pumps it seems it gets hot down there .and can be used for heating and energy extraction ..probley not cheap .

   Hector's Rotorvertor works.
 One can harvest AC from the series circuit with the capacitors, with a factor of 1.614 times the input, as tested by myself. Others have achieved 1.618 times, doing a bit better, scrubbing the grease from the bearings, and removing the neoprene seals.
 (This is over unity by standards, that Tiller, and Bearden, should have noted)
 Moving on, what would be the problem with energising the Transvertor using this capacitor circuit from the Rotovertor?
 I'm sure that Hector has done this a million times and powers his appartment building, just so, but it only occured to me now, to try to do this with that monster three phase transformer, I have been dragging around several hundred miles, after being a 450 lb toe stubber in my studio in Toronto.
 Duh, what if I tune, to power the first winding of that transformer, using my 3 hp WEG Rotovertor, as a source of AC?
 My capacitor tuning box has a fairly good range of capability of capacitance, and 600 volt oil filled capacitors.
 Could a country bumkin, like myself, then take power from the third coil of the big three phase tranaformer?
 Would it be a compounded factor of efficiency around 1.614 X 1.614, or would....nothing happen....nothing significant, just a meter twitch....120 volts in, 120 volts out...how about 220 volts in, and 220 volts out?
 All that is mere speculation, except for the Rotovertor which we have established the performance of.
 Sven is working away on the firing up of a Transvertor transformer.
 I am awaiting heat in my stone workshop, just so the Rotovertor doesn't bog down in its own solidified grease. Then there is the issue of picking up that transformer, using the Cat excavator to move it into the warm, cozy, heated, stone barn, before the big snow comes.
 I am curious if anybody has bothered with such an experiment, such as this, and if so, how did they go about it?
 Way back when, we had a file of pictures for each of us, on yahoo.
 For somebody like me, it was great to be able to check out everyone's file, to see the various projects on the go.
 Also, for the future, I thought it would be there, as history, a comforting thought.
 As it is, we are free to bumble along, repeating each other's failed experiments, and not trying to replicate the successes, trial and error, without checking the history.
 1.614X 1.614?
