Bedini's rally was followed by Jim Watson, a research scientist living in Colorado, Springs. Watson presented two working devices similar to that of John Bedini. Watson's smallest device worked throughout the presentation and the audience could see that the battery was constantly recharging. The largest device, which weighed 800 pounds, was only revealed for 10 minutes due to practical reasons. During this time, a constant 12kw load was removed from the device. The device was powered by two 12v car batteries.
