New accelerating gravity wheel ! Converted video from www.newenergymachine.com !

I was manually sliding the latch mechanism onto the latch rod connected to the 7 lb box. Then lifting it and pulling on the release pin. Very difficult with 7 lbs and at this point my design would have the springs connected to the 7lb box, so the tension would be some multiple. The catch is a small arc. I was looking at modifying the latch catch, little difficult and it may cause latching problems. The door knob latch seems much better at releasing with many times the weight.

Now this baby could sling http://en.wikipedia.org/wiki/Trebuchet.

Sounds good. Will you rotate the door knob to retract the latch?
Regarding the trebuchet, it seems as if its identical to Bob's machine but going in the opposite direction. In other words, Bob is raising the weights and slinging them down and the trebuchet is vertically dropping the weights and slinging the weights up. Hmmmmm. Let me think about this.....

Yes, I'm going to use a cheap non-locking knob and screw a handle to it which will be hit by a stop. But because of the release direction I have to change my design to go counter-clockwise instead of clockwise.

Another observation on Bob's video, when he first starts to brake at the end you see it at the top, then the next one is back down, then the end one at the top. He had talked about maintaining a certain speed for his generator. The video has a low frame rate, so it may be the top clips are just not caught by the camera at the controlled speed. In fact on that second to last one, you can easily see the missing frame, where it appears to be coming up then jumps off to the side.

The trebuchet is very interesting, just think if you intercepted the missile at release point and stored the energy, then used that energy plus gravity for the next launch.

The momentum from a falling object cannot return the object to the top, but how much extra energy is required to return the object to the top? Bob starts with his top springs compressed. I don't expect the sling from Bob's machine to be near as efficent as the Trebuchet but it may be enough to keep it running.

Well here's a concept drawing that I did based on using the trebuchet form. Might be something in here we could use. It appears that it could have the same bone-crushing torque  as Bob's....

Hi Jason,
Thanks. I'll be curious to see what Larry thinks as well. Of course, we don't know if this would work in real life or not. I wish I had a good modeling program but I don't.
