		<description>Sad to see all the usual naysayers show up.

Follow the money, why would some try to discredit their own potential power freedom, unless they&#039;re getting paid to slow down progress?

Meanwhile, the idea, warts and all, offered to humanity free for improvement, in the hopes it gets legs.

Not sold, but offered free...</description>

		<description>I enjoy reading this site occasionally but it really brings the site down when I see stories like this were either the story completely misrepresents the actual technology or the technology is a sham.

In this story the technology sounds like it doesn&#039;t obey the laws of thermodynamics, and the wikipedia article on it implies that as well.  Why do people get so excited over obvious snake oil scams?  After we get unlimited power from this tech let&#039;s all go run our cars on water, one of the lowest energy chemical states hydrogen can be in.</description>

		<description>I saw his video a while ago and it seemed what he was doing was running his motor with a magnetic break connected to it which would slow it down (a coil with a resistor to dissipate heat). He then changed something so that the magnetic flux didn&#039;t flow properly and the magnetic brake wouldn&#039;t work well anymore so the motor went faster.

It certainly didn&#039;t seem magical to me. But I guess for people with no knowledge of magnetic fields and coils it can look surprising.

&quot;During a demonstration to some AT&amp;T contacts the motor was spinning at its full rated capacity using only 75 watts of power, when normally it takes 250 watts to do the same work.&quot;

What does this mean? Standard electric motors are up to 90% efficient which mean that at 250 Watts they should generate something like 225 Watts of mechanical power. Surely they don&#039;t mean he was producing 225 watt of mechanical power with 75 input?

The only way I can interpret this to make sense is that he was operating with no load (an inefficient mode of operation for electric motors) and he managed to reduce some of the magnetic field loses which normally happen when the motor is &quot;idling&quot;. It must of been a fairly big motor for it to normally need 250 just for idling.</description>
