I am pretty sure that I have read this article on FreeRepublic several years ago. Probably as long ago as 2000 or 1999. Or at least about this DePalma guy.
These people are making gay Santa Clauses?!? That's just wrong?
i'd put it in a category including turning lead to gold.

I don't think this audience is ready for the real science contained in the Time Cube.
For the benefit of those who are too young to "have been there", my previous post was a not-so-subtle allusion that, IMHO, Depalma's device combines the theories of Nikola Tesla, the Maharishi Mahesh Yogi and Timothy Leary.
IOW ~ junk science.

In 1986, Bruce De Palma claimed development of an overunity machine (referred to as the "N-Machine") that was described as a closed path Homopolar generator with output four times more power than consumed. De Palma was been unwilling to help independent investigators, like PSITRON, analyze his device. One Electrical Engineering professor analysed this device, but skeptics claim the investigation contained a measurement error. De Palma was an associate of Richard C. Hoagland. De Palma died in 1997.

A homopolar generator is the only known
true dc generator. You build one by placing a rotating
conducting disk in a uniform magnetic field and collecting
the radial current. Homopolar generators feature extremely
high currents at quite low voltages. They tend to be rather
inefficient due to the current collection problems.
The nonobvious part comes from the fact that general
relativity demands that you cannot tell if a perfectly uniform
magnetic field is rotating or translating. It took us over a
century to straighten out the weird behavior of the Faraday
Disk version of the homopolar machine. The generation of
a homopolar disk depends only upon the strength of the
magnetic field and the relative speeds of the machine’s
stator and rotor. It does not matter in the least whether the
magnets themselves are rotating or not.
While not at all obvious, counter torques and counter
emf’s very definitely do exist in all homopolar machines,
just as they must in all electrical generators. No "overunity"
operation of any homopolar device has ever been shown.
Such claims are most often caused by improper ac power
measurement and misunderstanding reaction torques.

The homopolar motor
If you pump a huge current into the disk the magnetic field will generate enough force on it to make it rotate despite the brush friction. (Early experimenters made contact to the rim of the disk by making it pass through pools of mercury. Since mercury vapor is rather poisonous this is not done any more.) Unfortunately, generating large direct currents at low voltages is a notoriously inefficient process. AC can be transformed down to get a low voltage but the rectifying device needed to convert the output to DC tends to drop about half a volt, making the efficiency less than 50% before you start moving anything. About the only device which can generate large currents at low voltages at all efficiently is, you guessed it, a homopolar generator.
Defeating your own object
One hopeful inventor thought that you could generate an output voltage without generating a reverse force by attaching the magnets generating the field to the rotating disk. Unfortunately, this doesn't work. Only relative motion of the field and the current carrying disk generates a voltage. What misled this inventor was that he did measure a voltage when he connected a meter between the shaft and the rim of the disk. He hadn't realized that the ring magnets were generating two fields, one in the disk between the magnets and another toroidal field in the space around the disk. The disk wasn't generating a voltage but the wire leading to the meter was being cut by this rotating field and was generating a small voltage. Connecting a current meter would have shown an output current. However, this current would have reacted on the rotating field to slow the disk down. As I said before, you have to consider what is happening
everywhere in the system, not just focus on one part of it and ignore the rest.
The effect was the same as if the disk and magnets were stationary and a contact had been spun round the edge of the disk. The wire going to the contact would have been moving in a magnetic field and all the usual rules would apply.
Conclusion
No arrangement of wires and magnetic fields and moving parts is going to generate more electrical power than the input mechanical power or generate more mechanical power than the input electrical power. If you want to experiment, by all means have fun, but please don't think you are going to bring about an energy revolution. Above all, spend only your own money, not other people's unless you want to spend the rest of your life dodging irate investors.
In that case, how about this? I'm a Victim of a Time Coup d'etat.

We contend that for a nation to try to tax itself into prosperity is like a man standing in a bucket and trying to lift himself up by the handle.~Winston Churchill (1874-1965)
Interested venture capitalists can look here
You'd think 26 years would be enough time to build one and show the critics.
That's because there's usually no fraud in professional science, so they're not alert to scams. And most of them have very little real-world experience. (Yeah, I know, there's a whole bunch of folks who think science is all fraud. They're frequently the ones who promptly buy into the perpetual motion stories.)
