      Hi folks, here is almost the final design for my second prototype.

      [​IMG]

      The weights are going to be 3" steel bar and weight approx 10kg each.
      I'm excited to build it.

      I want to do 1, 2 & 4 weights first before deciding to upgrade the design.

      I believe this prototype will answer a lot of questions.

      Best regards,

      Paul :D

      ???

      Gravity, centrifugal force, and inertia don't depend on the earth's rotation. And solar wind doesn't spin the earth; the earth spins because of its existing angular momentum.

      I have designed the bellcrank part of it, but can't post a picture. Can I E-mail it to you?

      Dana, if the earth wasn't rotating then would it be falling through the universe? Do you think we could feel that perhaps?

      Basically the energy involved in the earth's rotation is colossal. This energy can be harnessed!

      Who knows exactly what gravity and centrifugal force are. No one knows everything!

      Do you think we have no way of knowing if gravity, centrifugal force, and inertia would exist if the world stopped spinning?

      Granted the solar wind may not be spinning the earth, my mistake. Who knows what the solar wind is fully doing?

      How can we honestly answer that?

      All very interesting though. I would love to know the exact facts.

      Best regards,

      Paul :D

      Maniacal Engineer, you are a brilliant human being for helping the cause, thank you very much! :D

      My email address is my first name then [email protected] with no spaces or dots.

      Look forward to seeing and understanding what you mean.

      Best regards,

      Paul :D

      Hi folks, here is the first prototype I built:

      https://www.dropbox.com/s/21tdq3o39s7oska/GravInert Experiments January 2013.mpeg

      It is a 1:3 scale version of the inventor's prototype 11.


      I decided to start with 4 elements to see what happened.

      The result were encouraging enough to make me want to build the prototype shown in my above post.

      The cheapest off the shelf one way bearings lasted about 20 seconds when I was using longer arms.

      I had to shorten the arms to make this video to show the design defects.


      The new prototype uses two heavy duty one way bearings per weight.

      The weight increase is 200x on the previous prototype!


      Should be interesting to watch!

      Best regards,

      Paul :D

      Apart from the one way bearing problem in the video, my theory is that there was not enough weight to overcome the friction of the bearings.

      With 200x more weight than prototype 1 and high quality one way bearings. I believe it should easily produce some usable torque.


      Maybe not enough to do anything amazing, but this is only a 4 cylinder engine. :D


      I'm planning on using 20mm diameter stainless steel for the axles on the 2nd prototype.

      What would be the best material to use for longevity?


      Best regards,

      Paul :D

      bearing longevity

      The one way clutch 'bearings' LOOK like bearings, but they are just clutches. you need to have a bearing to take the radial load, and the clutch takes only the torsional load. This may be the source of your short life.

      I suggest you study physics. You can learn about celestial mechanics (which have been well understood since Newton's time), but also basic mechanics, with the concepts of conservation of energy and momentum, which are easy to learn and understand... and you'll understand why the machine you're trying to build can never work. But don't feel too bad... you're not the first person to try to build a machine of this type.

      Paul T, why don't you explain to us what the principle is behind the way you believe the machine will work? And what you expect to see for input and output torque and rpm? For the same of discussion, assume you have perfect frictionless bearings and no backlash.
