You guys will revel in this :)

The GHD is nothing more than a fancy flywheel. He talks about spinning the device up, and then locking the weight to the helix to extract the energy.

Could be used to store energy, but energy producer it is not.
 
Hmmm .. a somewhat novel variation of the perpetuum mobile concept (the way it is claimed, if you feed the energy the device produces back into the device itself, it will run forever, with a net surplus of energy produced) - where to start on it?

It appears that it, by moving a hill, keeps a ball in a constant vertical position. Which implies that the hill and the ball are constantly accelerated sideways at 1G (~9.8 m/s^2). The amount of energy you spend on accelerating the ball sideways (which is energy YOU add, not energy supplied by the gravitational field) is exactly the same amount of energy that you receive by picking up the ball afterwards, while the energy you use to accelerate the hill goes to waste.

I'd rate this as one of many pseudo-scientific ideas/outright hoaxes floating out there - sharing the same problem as a lot of them: totally unworkable, but written well enough, convincingly enough, with just hard enough math, that someone without higher education in the relevant field (in this case, physics) won't be able to cut through the crap.

Oh thanks for the confidence boost. ;) :p

The page looked legit. :LOL:
