What do you folks think? Yet another flop?

In English someone?
I would have an easier time believing he had built a machine that captured the Force than a perpetual motion machine. The laws of physics are not negotiable.
All I really got from it was:
"Magnets" "Unexplainable" and "Even if it's not perpetual, it could still increase the efficiency of motors"
That last part is a good thing, no matter what.
in the words of Homer Simpson:
"In my house we obey the Laws of Physics!"
The Laws of Physics get revisions all the time, there are no absolutes, only what we currently know...until we know more. It's not a point of negotiation, it's a point of discovery, there is still much we don't know, to believe we know an immutable set of "Laws" as pertains to a universe barely understood is not only arrogant, it is assinine and makes as much sense as the church burning early scientists for questioning and disproving Biblical "truths". Never close your mind because you know something can't be done, because there are no "can'ts", just "haven't yets".
The difference is that to be of any value a "perpetual motion machine" needs to perform work without any decrease in it's energy state and that ain't gonna happen, trust me.
I'm a day late and a dollar short. Steingar, what Henning said.... Specifically that point about arrogance.The Laws of Physics get revisions all the time, there are no absolutes, only what we currently know...until we know more.

Steingar just made my point, being as fanatical about the "laws" of physics as any other person might be about their religion.
Bullhockey. There are no exceptions to the laws of conservation of momentum. None, and never will be. I could not rule out that the dude's dohickey somehow tapped into some heretofore unknown source of energy (hence my comment about the Force). There could easily be sources of energy unknown to us at present that could be harnessed by some unconventional mechanism. But not a perpetual motion machine. Even the moon will eventually run down in its orbit when its hit enough hydrogen and meteors and whatnot. It probably has already.
Think about it for two seconds. We've been in a energy crisis for the last 30 years, with energy prices increasing on a regular basis. If even one of these crackpots were for real (and there's been a lot of them), you'd be running a perpetual motion generator in your Buick. All I see is a video which would be easy enough to gimmic. Seriously, if the guy is for real he's the next big thing, there will be power stations and such, he'll have more money than the House of Saud, and I'll be happily eating crow. Gosh perpetual energy with no fossil fuels, nuclear waste, or environmental contamination. Who wouldn't want that? But I'm honestly not worried about violating my vegetarian regimen just yet.
Am I a fanatic for insisting that 2+2=4? Same kinda thing. Don't mistake ignorance for wisdom.
Well, like I mentioned in another thread, 2+2 can equal 5 (for extremely large values of 2 or extremely small values of 5), so....
2=1 but that doesn't mean the math used to prove it is right.
You are the reason people cannot understand the difference between Religion and Science. Just stop talking, it works better that way for everyone (especially your own self image).
If that seems rude, go read some basic science book, and find how many times the words "irrefutible" or "fact" appears. Then come back and tell me that there is ANY part of Science that is not open to change.
The sun goes around the Earth, Steingar.

2+2 does equal 4.
Or it means that you're a physics geek, and you're measuring something. Or you're telling a math joke.
http://en.wikipedia.org/wiki/Two_plus_two_equals_five#Science
The Sun and Earth rotate around a point in space where their gravitational pulls are at equilibrium with their orbital energies.
I reference my earlier post. 2+2 does equal 4.
Looks like theoretical interpretation of facts not supplied in real world applications.
2+2=4 +- 1.0
Therefore:
2+2=4 -1.0=3
AND
2+2=4 +1.0=5
Thus 3=5 for very large values of 3, or small values of 5 for an error of +-25% for a total potential of 50% error.
That doesn't change the fact that you still can't put 62.5 gallons in a 50 gallon tank without making a mess. (Trust me, I've tried it several times with my RV fresh water tank and all you get if you're standing anywhere near the inlet every single time without fail is a bath)
Think about it.
IIRC rounding is commonly done to significant digits given, not beyond the last digit supplied. Also for (statistical?) averaging of data points to avoid tolerance stacking you could so something like 2+0.5 then 2-0.5 to get an average between the data points.
IOW, round 2 to no decimal and/or statistically = 2.0
Integer 2 + Integer 2 = Integer 4
Anything else will put you in the trees at the end of the runway.
"It depends on how precisely we can define and subsequently measure 'apple'."
But in the end, it's just a thought exercise with little meaning in the real world. And, as it happens, a fun way to annoy people who use "2 plus 2 equals 4" in their arguments.
Agreed. Just fun and games...Unless it's -15F outside while putting 35F water in the tank without a jacket on. BTW, any victi,um,volunteers for a first hand practical application experiment of 2+2=5 thus 5=4 being correct during the next cold spell?

I'm not sure what "basic science books" you've read, but well documented "scientific methods" involve developing theories and devising experiments (thought or laboratory) and determining whether or not the results support the theory. Granted that some so called "scientists" have jumped to conclusions without following scientific methods and others have by mistake found "evidence" that their flawed theories were valid, but most of the high impact changes in "scientific knowledge" have been the result of a combination of refined measurement capabilities coupled with innovative, open minded thinking.
I absolutely hate discussions in which both religion and science get discussed at the same time. They are not comparable at all, and do not belong in the same sentence.
Yes, the "laws" of science have undergone revisions over the years. Sometimes drastic revisions. Any scientist who doesn't admit the possibility of this happening can hardly call themselves a scientist. Evidence accumulates, that's how it works. I teach my students about conservation of energy and the 2nd law of thermodynamics... I am not teaching them a "religion", I am teaching them a model of the universe which has held up under detailed and precise scrutiny for over 100 years, a model upon which we all place our trust every single day.
A major pet peeve of mine is those who know enough about the scientific method to say, "I think the laws of physics might be wrong!" but then they happily step into an airplane, turn on a computer, microwave their food, etc... which is implicitly placing your trust in these laws, many of which are even *newer* than 100 years.
