Here's my Super efficient Hog Stirling motor, powering a 48v server cooling fan that has been converted to an Ultra efficient generator, which in turn is powering a 10mm led light. I've fueled the Stirling motor with one teaspoon of ethanol and it provides bright light for about 6 minutes, using less than 1/2 teaspoon of the ethanol. I was surprised how little alcohol was consumed, so I checked the burner again, using a syringe. It consumed 1 ml every 4 minutes, or, 20 minutes burn time, per teaspoon of ethanol.

Stirling engine runs fan, pump, charges battery at same time
Stirling engine runs fan, pump, charges battery at same time Video Clips. Duration : 2.00 Mins.
In this video I show that this little engine can drive a 20" fan at 570 rpm while charging a 12-volt battery and running a 12-volt pump to provide its own cooling water, all at the same time. Note that it's charging the battery at about 1 watt. At the end I show the engine just charging the battery and putting out 4 watts of electrical power (13.25 volts x .304 amps = 4.028 watts). The engine drives an inkjet printer PM motor as a generator using the original toothed drive belt for higher efficiency. The little 12v pump is one I found online and runs off the generator. With the rheostat I can control the water flow from it, and also the current draw. It's pretty satisfying to see one's engine operating standalone and doing some useful work. The large Stirling engine in the background is another experiment.
