Bob Kostoff, a Canadian, has created what he calls 'The Gravity Powered Machine', a self-sustaining engine that costs less than half of a small wind turbine. The machine, which requires only a little juice to get it started, looks much like a teeter-totter but works like an overbalancing gravity wheel. It is using a series of sliding weights that, with the help of the earths gravitational pull, force the unit to continue spinning around in a circle.

Kostoff, who has built some five working prototyptes, says the engine provides as little as 10 foot-pounds of torque or as much as hundreds.

Saw this on the site home page:

New Machine Specs:

Length: approximately 8 feet
Width: approximately 4 feet
Height: approximately 6 feet
Weight: 3850 lbs
Torque: up to 3000 foot lb


And this was on the Overunity forum:

"Bob's new demo unit is suppose to be the start of his initial production units. Apparently he was successful in getting a local company to start producing them. I'm hopeful that his website will present clear photos or video of its operation."

I will be posting on the web site the progress of the construction of the machine I am building at home. Hope to have it completed soon. It will generate around 1200 foot lb. of torque @ 40 to 50 rpm. I have a 20K Watt generator that it will power."

How it Works

On May 11, 2007 Bob Kostoff wrote: [1]

The machine is totaly independent. It requires no external power.

It works the same as the unbalanced wheel. The trick is to get the weight back to recycle it. There are 3 procedures I have used to do this.

The air cylinders I use as a shock absorber, similar to that in a car and it also stores a bit of energy that locks the 2 weights together almost at the bottom. A set of springs are also at the end of the rotating wheel to absorb the impact of the weights. It trips a leaver that activates a pin that acts as a pushrod to return the weights. When the weights are attached they only need to be returned 1/2 the distance then centrifical force takes over and then they start to accelerate to the other end. The closer to the half way point the 2 weights get the less energy in needs to move it. Once the weights are past the balance point they accelerate and generate many times their weight which creates the the energy needed. The faster rotation the larger the force. Without the springs and shock absorber it would destroy itself.

Hope this will help, and I am glad to share it with you.

The working model will be totally enclosed.

There are no springs that are wound. I am loosening the disk brake that stops it when needed.

Older Machine

Quoting from http://www.newsourceofenergy.com/machine.html

First I have to loosen off the disk brake until it has a small amount of resistance, then give the machine a little push. As it starts to rotate and picks up speed I tighten the brake just enough to control the rotation speed.

This is normally handled by a governor on the newer machines.

The machine must rotate at a pacific speed to keep the generator constant.

To stop the machine I just tighten the crank on the disk brake assembly and it works the same way as the disk brakes work on a car.

Newer Machine Specs.

Quoting from http://www.newsourceofenergy.com/machine.html

Length: approximately 8 feet
Width: approximately 4 feet
Height: approximately 6 feet
weight: 450 lbs
Torque: over 100 foot lbs and up

And quoting from http://www.newsourceofenergy.com/index.html

Each unit is totally enclosed for safely protection against moving parts.

This new engine is the product of years of research, frustration and perseverance.


Applications

Kostoff speculates that the system could generate the power needed for electrolysis, to produce hydrogen to power a vehicle.

Patent

"Patented"

Despite six months of looking, no one reviewing this technology has yet found a patent number that corresponds to this invention.

One person questions the claim to a patent due to its closeness to the disign at http://www.fuellesspower.com/6_Gravity2.htm it is called energy converter. here are the links http://www.freepatentsonline.com/y2009/0051169.html http://www.faqs.org/patents/app/20090051169

Validation

This device has not been independently validated that we know of.

On Sept. 7, 2007, Sterling D. Allan of the New Energy Congress sent a message to Kostoff asking him if he would allow someone from the NEC to inspect his device and validate his claims.
