Wasn't It Supposed To Be on The Market in 2003?

It was supposed to be in operation, not on the market. I haven't seen credible science behind the idea. But if he can legitimately and repeatably make it work, a lot of scientists will be scratching their heads and rethinking theories, including the sacred second law of thermodynamics. Then they'll move on to figuring out when we'll run out of vacuum energy, and will pass laws forcing conservation of vacuum energy.

Using the gas-powered driver to 'kick-start' the system means you're going to input a certain amount of energy, in the form of mechanical torque. Normally, this would start the entire set turning. (Make sure you have enough of a kick to turn the entire inertia of the set, AND accelerate it up to the generator speed!) Once you've reached generator speed, drop the generator into the circuit so that you have terminal volts ... but essentially zero current draw. It's not a completely 'lossless' system - the electrical generator efficiency is only about 98 percent at the best of times, and a better approximation would be on the order of 96.5 percent. You then engage the field of the electric motor, so that there will be something there when you start using it to drive the electrical generator portion. Again, the machien is not 'lossless' ... it's probably a good bet to approximate it at 95 percent efficiency (or slightly less, if it's a DC machine). This means you're chewing up about 9 percent of your generator output in accounting for the electrical losses of the system. And recall that a generator is simply a means of transforming energy (from mechanical to electrical). This means you have to PUT IN that extra 9 percent from somewhere as well ... just to keep the loop cycling. Motor-Generator sets are quite common; the large dragline shovels, for instance, use a synchronous motor to power several direct current generators, which in turn supply power to the direct current motors actually operating the various portions of the shovel. Older process lines used the same idea to power their process; a back-room full of motor-generator sets connnected to buses to transfer electrical power to the machines operating the various stands. Even when testing two machines, there has to be an extra source of power to cover the system losses (both electrical in each machine, plus mechanical in the drivetrain). This is done all the time in facilities which manufacture electrical motors and generators ... and have to 'load test' them. Basically, there's no 'free lunch'.

The laws of physics sort of got in they way. One of the fundamental principals is conservation of energy. People have been attempting perpetual motion machines for centuries. They never work.
