Rosch taking orders on OU Bouyancy device.

[minnie]

    I can remember the day James Kwok "flew into a temper"
     The people that flew into the building were obviously highly competent and had
   planned the whole thing meticulously.
     I have come to dislike anything to do with Peswiki.
   I've lost faith in the Tinman.
      Try putting a 7kw motor on those buckets and water contraption and see what
   happens! My sewage machine runs off a half kw motor and it's amazing how that
  tiny motor turns a 6ft x 12ft rotor that weighs a ton or more.
     It's amazing how much current that little motor uses on no load versus on load.
   There is very little difference,ie. efficiency must be very poor,try telling that to the
  motor-generator crowd.
    Sorry Tinman-I really do appreciate your enthusiasm!!!!!!

In reply regarding jams Qwok h spent jail time. His devices never worked or panned out, I have covered many articles on him over the years.

He spent time in jail for a land rental bungle,not because his device dosnt work. Im sure the UN it self wouldnt promote a non workable device to the world.

I in no way support the device being discused in this thread-no evidence to back it up.
I also in no way support peswiki or sterling allan.
I do my own thing,and my own reserch,and as it stands now,all the evidence supports the hidro+ unit.

You may want to check the numbers but working in SI,

290 psi gauge is 2100.8 kPa absolute.

during isothermal compression PV = constant so 2100.8 * 1 litre = 101.3 * x => starting volume was 20.73 litres.

The amount of air is n = PV/RT where R = 8.313  J  K-1 mol-1,  and T = 280.15 K (8 Celsius) =   (101.3 * 20.73) / (8.313 * 280.15 )  =  0.9 mol of air.

So,  work performed during isothermal compression = -  nRT ln(V/Vo) = -0.9 * 8.313 * 280.15 * ln(1/20.73) = 6354.2 J or 6.35 kJ

You compressor will be less efficient than that so adjust by whatever efficiency factor you think is appropriate,

lets say it is 65% efficient so 6.38 / .65 = 9.8 kJ

The value is moot though. The same maths that allows you to calculate this number can also be used to deduce that you can never achieve more output than input and worse still the overall efficiency is proportional to the temperatures of the hot and cold sources.

So 6.35kJ of energy is stored in our 1 ltr vessel at 290psi.,__im guessing the 6.38 is a typo?.
And 3.45kJ is lost via the compressors efficieny asuuming it is around 65% efficient.

And is it right that to halve the pressure,we double the vessel volume ?

Yes 6.38 should have been 6.35. Halving pressure will double volume.

I see here that the device you seem to be describing is similar to an OTEC generator of which a few exist in Hawaii I believe.

There is nothing to stop you utilising buoyancy to take advantage of the temperature gradient in the ocean to generate energy. However due to the small difference in temperature overall efficiency is low. Unless pumping losses are low it will not function.

The solution is to make the device very large and make it the compressor itself rather than use small external pumps to evacuate a chamber at depth.
