If you wish to be pedantic, then a horsepower is 746 watts, and a watt is
equal to 3.142 BTUs
The power (watts) are used in the electric motor inside the sealed unit
compressor, and heat (BTUs) are given off in the process, which in turn is
picked up by the refrigerant and has to be eliminated.
The numbers are theoretical, and I have not included any losses, so shoot

He meant that it should be BTUs / hour to equal watts,
but then watt hours can also equal BTUs.
The hours just need to be in the right place.

It may do, but at what cost.
I just recently bought a 1HP reverse cycle AC to heat and cool my
It cost me $50.
Will your wind driven system with its turbine , mast to hold the
turbine , installation costs of the tower and foundations plus all the
pipes and air exchangers cost $50 or less.
Somehow I dont think so.
People get far to obsessed with efficiency and lose sight of reality.

I think his point is you can get "free" energy from the environmernt
but, by the time you amortize your capital expense and maintain the
system it will be the most expensive way to heat/cool your home. That
is why I suggested using junk car parts or other "damn near free"
stuff for your expiriments, to prove the concept and have some fun
without breaking the bank.
It will never be cost effective, the only question is how much do you
want to spend to prove that. Actually if you can make a somewhat
effective system for a few hundred bucks you might actually cool/heat
a small space for (almost) free.
