Jasker Power System
In what some claim may be the greatest invention since the wheel, an Irish inventor's 23 years of effort may have finally paid off. The 58 year old electrical engineer claims to have invented an electromechanical device that runs on 12-volt batteries and is capable of replenishing its own power supply.  Once powered up, it is capable of running indefinitely - or at least until its parts wear out.
The device was demonstrated to a group of Reuters reporters in Ireland in early 2002.  The device, about the size of a large dishwasher, was hooked up to 3 100-watt light bulbs and ran continuously for over 10 minutes with voltage measurements taken at the beginning and end of the cycle.  Amazingly, the voltage actually increased indicating that the device had not drawn any energy and/or had replenished any energy it had consumed.  The device continued to run for 2 more hours while reporters took pictures and questioned the inventor (who refused to disclose his name).
