Or, like every other perpetual motion cheater on the internet they just have some form of ducted air blowing across the top of the device.

They ought to have prisons where the prisoners learn remedial science all day long so they can send the perpetual motion nuts along with the dwfttw, young Earth, Intelligent Design, Ayn Rand, and all associated believers along with the climate change deniers there until they can pass a basic science aptitude test.

The world would be a better place.

"This technology has been suppressed because it is a threat to the profits of the energy corporations."

Umm yeah. They're doing a bang-up job of it too, cause YouTube pulled this video down within seconds.

Oh no, wait... they didn't.

Perhaps you should go build a car like that Chinese guy did that has a fan hooked up to a generator that feeds energy to the car's battery. Or try some DWFTTW videos for a change?

In conclusion, physics does not work that way! Good night!

This is exactly how I felt on the, DWFTTW thread.

Energy isn't free, it has to come from somewhere!

WHUAAAA!

No, you don't get it, energy can't come from the GROUND! It doesn't work that way!

WHUAAAA!

Look, when you say, "Energy is coming from the ground." What you mean is the car is using it's own momentum to power it's forward movement, don't you realize how stupid that sounds?

WHUAAAAAAAAA! PTUI!

Okay... I give up.

The moral of the story is, never argue with an idiot, they'll just drag you down to their level and beat you with experience.

No, sail boats and Ice 'sailors' can go faster than the wind but not DOWNWIND.


"not downwind" -> if you mean:
1. "icesailors can not go dead downwind in a STRAIGHT LINE faster than the wind": than I fully agree with you
2. "ice-sailor can not go faster than the wind downwind VMG-wise" (i.e. they can NOT catch up with the wind downwind or with a balloon just drifting with the wind by zigzagging downwind), than you should reconsider or ask some of those guys. That's a fact!

Let me know what your position is on point (2).

If you don't agree on point (2), than I'm not going to bother you any further. ;-)
But if you agree on point (2), than that should be a good basis to believe that the trolley concept could work.

BTW, I don't think I need to specify how many physics classes I went through, not sure if it is relevant at all here, but I can safely say it's more than what you currently think. No worry! ;-)
Let me know if all your physics courses allow you to see where this guy might have gone wrong: http://home.roadrunner.com/~tadhurst/DWFTTW.htm

This video is part of the "DWFTTW - Downwind faster than the wind" debate happening at boingboing and various other places.
