Slightly different devices - the Sterling Engine acts like an old fashioned steam-powered train, and is intended to produce motion. The OP's links generate electricity, which can be used for a wider variety of purposes. MSI's HeatPipe + Sterling-powered fan intrigues me; I wonder how effective and flexible it is.
It seems like something is missing from the ScienceDaily article; I don't follow how heat causes their device to resonate like a tuning fork.

Well, yeah, they're different, one is a very simple way to utilize heat energy and one is a complex one that caused the company to go bankrupt.

Thermoelectric power is generated when heat flows from a hot source to something colder. That means the energy would have to be captured from the parts of your home that are poorly insulated, where it's hotter outside than it is inside and that is warming up your room. The A/C could use that power to pump the heat back outside (from a cooler room to a hotter outside) but that wouldn't make your room cooler since you'd have to have more heat leaking in than you're pumping out.
The auto A/C can work because the you can generate power by using the heat from your exhaust pipe that's already going to be warming the outside air and which is independent of the heat flow in or out of the passenger area.
I meant using the heat from the compressor which reaches quite a high temp.
Would still draw current, but would regenerate some of its own thus cutting down on mains power draw.
Put one side of the thing on the compressor and the other to outside, and voila, hundreds of degrees difference.
Same effect as the exhaust pipe and the external air temp.
Won't be much longer.
Instinct-that which uses the other 90% of the brain conscious thought does not.

Does the sterling engine cooler actually ship? Would love to play with one
Can I use a portable Air conditioning unit in a pop up tent trailer?
Im going camping this summer and its going to be HOT. I have a 6 month old that I will need to keep cool. We have electrical hookup at the site. Is it safe to use a portable air conditioning unit in a pop up tent trailer?
