Unfortunately it is not. :-( Although it seems to have an
energy gain all of the output energy is explained by the input.
A little logic and some plain old accounting would prove this
Say you start with ambient air and extract from that air by
cooling a constant 1000W. Your energy cost (assuming 70%
efficiency) would be about 1300W. The output heat would of
course be 2300W (good accounting)
Now if you could use this output at a greater efficiency than
is allowed (say 70%) then you built an apparent perpetuator.
You would be extracting something on the order of 1600W
(without actually doing the math) offering you an apparent
overage of 300W.
This is why we all like to believe :-)
Now here is the problem. The best best best use of the heat
that can be achieved is only 50% (there are physical and
mathematical reasons for this)
Now lets re-do the experiment with this knowledge.
1000W extraction at 70% efficiency the consumption will be
1300W and the output will be 2300W (ain't that cheerful)
Now if 2300W can be converted into usable energy at 50% so you
can actually use 1150W leavin yall about 150W in the ditch.
But here is something the experiment does not consider. You
are forgetting about a 1000W heat hole (gradient) that you left
behind. From which you should be able to extract an additional
500W (a little pipe dream) offering you an overage of 350W
Now if at some point one of us could actually achieve that 50%
we can get started. My stuff is peaking out at about 30 wich
leaves this expariment back in the accounting ditch.
