mirco-chp which is quite interesting and seems like North America isn't adapting the technology fast enough.   Canada with it's current high heating costs during the winter months makes it an ideal product.  

Basically it's a gas heater but there's an engine that does the burning which makes electricity. It works best with a household/building that have constant heating needs.

How would a heater make electricity?

Gas burns in engine, engine turns coils/magnet makes electricity, and water is used to cool the engine which is used as hot water or heating.

There was a great flash of it working but I don't see the point in search for it for you.

Interesting hybrid. Gas generators are pretty inefficient in their heat loss; and marrying this with someone who loves heat, like a water heater, ingenious.

Although, I wonder how much electricity a tank of propane can make with it -- given the fact that a large portion of the energy is intended to make heat.

The video was avi you are in luck.

It's operational in hotels where there are huge water heaters so on.   There's a small home unit by whispergen which I think generates 1000watts but it depends on how much water you are heating and goes back to the grid.   It turns off when not in use and I believe uses some power to start up so not worth it for say 1 person on their own.

There are figures so on that people have for these units which you can easily google.
