Centrifugal gravity wheel

[inroades]

  Hello all
   I have not posted here before. I have a Centrifugal Gravity Motor I designed that has been looked at by a couple engineers and has promise. I have no idea how to post pictures and share this with you as I would love your input.  Can you help me.
   Thanks

Hello

I am not a engineer or claim to be particularly clever but this idea is one that I have been working on close to a year now. I have had two mech engineers look at it and tell me the numbers work but PM doesn't exist. My drawings are just terrible and my explanations are poor and I hope that you can understand the concept.
          Here is the basic idea, there are two power sources on the machine. The primary is the wheel with a pto at the hub and the secondary is from the power plate below attached to a center shaft.
         The wheel has weights that slide on spokes with latches that hold them in 2 positions, Inside closest to the hub (up position), Mid is the outside latched position or power position, and a free or unlatched outside position. The wheel must be turned or started to about 1.5 gravity in centrifugal force before the weights can be released. 60 to 75 RPM on a 6 foot wheel I am guessing. A weight is released at just before TDC and centrifugal force powers it upward to the upper power ramp the ramp converts the centrifugal force to rotational power and the weight latches in the mid position. Just before BDC the weight is released again to free fall but is still attached to the slide. (It does not come off the slide)
   Centrifugal force increases on the square in relation to rotation speed so centrifugal, rotational, and gravity will combine to create a vector that the weight can accelerate along towards the lower spring ramp. I believe a 50lb weight at 150 rpm will have approx 350lbs of force that will be stored in the lower ramp spring and the spring returns a 50lb weight to the inside latched position. The movements of the weight at the lower ramp are linear so centrifugal forces don't need to be overcome.(centrifugal and centripetal forces are equal but don't act on the same body)
   The secondary power source is from the centrifugal force differential. the moment of the power side weights is greater and they are moving faster than the return side weights. I believe that will create a strong internal force or torque to the power side of the wheel. If the wheel where mounted on a triple pedestal the mid plate could be geared or driven by the upper and the power harnessed. The cool thing about this power is it will be pure force or torque the plate could be stopped completely without effecting the wheel.
   Here are some thoughts.
      I have completed some crude tennis ball testing, they are about 60% efficient and at 150 rpm on a 6 foot wheel the ball will rise 12 to 15 feet above the contact point.
      A spring engineer tells me that if I preloaded correctly I can expect 99 percent efficiency
      Individual springs on the weights may be better than one under the ramp.
      Release timing(s) of the weights can work as a throttle.
      Friction at the lower ramp will be high, I may need to allow a spoke to hinge 10 to 15 degrees while the spring compresses.
      If the compression friction is to great I may have to find a way to disengage the weight all together and catch it on the inside.
      Ramp angles will be critical to RPM
      Latches need to be frictionless maybe electro magnetic
      Maybe opposing permanent magnets would work better than wheels.
      Maybe just maybe I can make power on the lower side, as the weight will return with a lot of force, timing that event will be tough.
      I believe I am comfortably inside the terminal velocity window up to about 400 rpm on a 8 foot wheel.
      If the wheel requires a little assist maybe the combined output would go OU.
   I am trying to attach the pictures and the numbers on the pictures are my best guess. Hows that for a disclaimer.
   Thanks all for looking.
