Short of it: you cannae violate the laws of physics, Captain, though
sometimes they can be bent or mangled a wee bit
Sorry if this is a problem, but there are some specifics that I think
you may be not be getting a good grasp of here.
Most important point: a heat pump is not an energy generator, it is a
conveyance device. Do not take the info of 300% efficiency to mean
that you are creating energy out of thin air, because, you aren't.
What it does mean is that, as an example, if you have a heat pump at
300% efficiency transfering heat, you are INPUTTING 1 part energy, and
it can use that energy to convey, or move, 3 parts of thermal energy
from point a to point b, the heat or cold is what is already there. I
know this sounds like you're creating energy from nowhere, but it's
NOT a generator. It is perfectly possible for a train that is using
10kWh of total energy to pull the equivalent of 30kWh or more, of
fuel. As it is used for the transfer, or conveyance, the 10kWh is
immaterial. While it is unlikely, it could just have easily been a
small engine that pulled the load. The energy is spent in the trip,
and you can only carry what you have available to you, it doesn't
magically make coal appear in the boxcars.
Sorry but the perpetual motion bit does not make sense in any
schooling i have everr taken myself. Even a solar powered generator
is, at best, a low-efficiency conversion device powered by the closest
large-scale Hydrogen-based fusion reactor in our little area of the
galaxy, and stars DO die, you know...
Not perpetual, just extremely long lived... exactly
If you get bored, try these things at home (dons Mr Wizard hat):
Freeze a coffee cup, make a batch of hot coffee, measure the temp of
both the cup and the coffee. Pour a cup of coffee.
Wait until the two temperatures even out, and I do NOT mean shoving
the cup into the freezer here. You get a warmer cup, but the coffee
gets colder. Now for the real kick in the head. Put the same amound of
coffee into the cup, at the cup's new temperature. You can measure
that a LOWER change of state has occurred, because there isnt as much
difference now. This is brutally simplified, but what it means is that
eventually, the sources of energy themselves will be at equilibrium,
and without a difference, there is ZERO change. Period.
The same can be done with our newly warmed up coffee cup, and a
pitcher of water from the fridge. The exact same process, only the
temperature is a lower middle point.
This is a very simplified experiment, so I know it isn't 100% correct,
but it illustrates the problem with your powering the heat pump by the
pump itself. There has to be sufficient thermal difference to power
it, and at some point, unless you put more energy in the system to
compensate for this, eventually you have a dead system.
Didn't mean to be long winded, but I am tired, and get long-winded
when I haven't had enough sleep
Flames and corrections are welcome. Corrections are welcome, flames
are welcome to /dev/null... Sorry for boring everyone
