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.
