Hi All,
This patent popped up and looks very interesting.
US 20130047754: Mechanical advantage machine
http://www.google.com/patents/US20130047754
I like how he combined several different mechanics on this one.
- Heavy mass (4000lbs with a 5hp prime mover rides on track)
- Precessed track(displaced by moving weight)
- Leverage through the displacement of track
- Flywheel
The lever is really clever how it's offset from the track in the center. Using the precessed track is also very smart, the weight doesn't have to be lifted only driven horizontally to move the lever.
Doesn't give any indication of output though.
Peswiki news has some info and numbers on the machine.
