Title: Teardrop Cam
Post by: prajna on September 21, 2009, 05:51:28 AM
Hi All, sorry for my long absence, I have been busy with other things and have only recently had the opportunity to look at free energy devices again.

Attached is a wm2d model of a system with a very small balance point.  It runs nicely in wm2d but I haven't set any air resistance or friction and it doesn't appear to accelerate, so I suspect it is down to a wm2d rounding feature or some such. I would be grateful if someone could check it.

There is a nice mechanical logic to it though :) It is something like trying to balance a pin on its tip. It is open source and free for all (as all knowledge and discoveries should be).

Let me know what you think.

Will do. I'm working on a video. Looking at the tracking plot for the centre of mass it does appear that it accelerates but very slowly. I have found that many things in the model can be adjusted and it still runs.  The version I will video has no counterweight on the end of the cam shaft and still runs! I have added a node to the end of the cam shaft just so I can plot its centre but the model works just the same with no node, with a counter weight, with a longer or shorter crank shaft, with different counterweights on the rotor, with different slopes on the slider (even a horizontal slider. For anyone who does have wm2d try adjusting things and see what you get.

Sorry folks, I can't seem to get the avi small enough to upload. I'll find somewhere else to upload and then post a link.
