Collecting energy from thin air

[Low-Q]

I wonder why it hasn't been more research in collecting energy from the airs temperature. A heat exchanger is moving energy from the outside air to heat the house inside. The applied energy to the pump is 30 - 50% of the energy you can get out of the heat exchanger. This is possible because there is about 5 x 10^18 kg of air around the world, and it will take litterally forever to emty the potential energy which the air carry with its temperature. The air is a limitless "battery" of energy and making a selfrunning engine which is running on air temperature only is absolutely possible. It does not violate any thermodynamic laws, and useful energy can be harvested - not milli Watts but kilo Watts from a moderate sized device.

So why isn't there more research in this field?

An average heat exchanger can produce about 3kW of heat, and consumes about 1kW to run the pump. At the best conditions, 4-5kW output at 1kW input. That means it is possible to make a heat exchanger which is actually PRODUCING electric energy to supply the whole housholde the whole year around. You don not even have to connect to the grid. All the power you need is in the air outside.

you know why... cui bono

There is research being done on this its just that they can't publish anything on it yet!

I see. It's too much oil and coal to be burned first? LOL

What do you mean? For whom this is good for (cui bono)?
