This is the first stage of my project to convert pendulum motion to rotary motion. The next part will include a large neo magnet and driver coil to propel the pendulum. The driver coil will only have to operate for 50 seconds out of an hour because the driver coil pulses will only be 25 milliseconds in length. The period of the pendulum is 1.8 seconds which is determined by its length. Therefore, the coil will fire 2000 times in one hour. 2000 x .025 seconds equals the 50 second run time/hour.

  • thats awesome, how long does the pendulum run , ? from what I see, those are weights inbetween the spokes?I'm curious, would a secondary pendulum (swinging the opposite way at the right interval), speed up the shaft ? My guess at some point the speed of the central shaft can only rotate in relation to the speed/force applied by the pendulum .I wonder if larger gear/weight or a combination of gears would increase the final output.

  • @nightkraawler

    Thanks. There's 5 pounds of weight in the spokes to act as a flywheel. The pendulum runs for about 5 minutes before you need to push it again. You could add a second pendulum but you would probably have to add some way to time them or you could add a second wheel/freewheel on the same axle. Changing the gearing would increase the output but would drain the pendulum faster so that would be the tradeoff.

  • im looking at somthing like this as human power to back up a submarine should other systems fail . to run a compressor to get back to the surface. weight as you might guess has no bering as to get somthing hollow to sink it takes lotts of weight anyway.

  • @datzfast

    I would think that the concept would work perfectly. I guess the only limitation would be the interior vertical distance of the submarine. Best regards!

  • @purelyprimitives hey thanks , listen three years ago i saw a you tube about a canoe powered by an inertia drive it was in a swimming pool and moved about 10 mph now i cant find it anywhere all reference has disappeared completely. everywhere i need help finding it it looked to be from the 1960 era. i suspect the data is now highly classified.

  • @datzfast

    The only thing I could find was the following scivee.tv/node/17540

    but I don't know if this is the specific device you meant.

  • Intriguing setup.

  • Anything without piston rings would be a start. Anything over 50% efficient would save lots of fossil fuel. Hats off when you finish the prototype.

  • Wave Power Generation

    All you do is have plastic bouy (or a large pontoon for KW power) connected to a cable that goes to an anchor pulley on the bottom of the water connected to the contraption shown above on the beach Wave Power Plant. The movement of the waves up and down cause the floating bouy (or potoon) to move creating left & right tension on the cable that drives the Power Plants generator machanisms flywheel on the beach. Then you sell that FREE power to consumers.

  • @datzfast Its not classified, you are thinking of the GIT gyroscopic inertial thruster. Type that in and you will find the videos you are looking for.

  • been thinking a similar idea, make that bicycle wheel in to a generator (magnets and coils etc) have that charging a cap which fires an electromagnet say every 6 full swings or so which pushes the pendulum to keep it going by itself. you could put many coils and magnets around the wheel plus put a few monster power magnets on the bottom of the pendulum which swing by coils underneath, you would surely be able make enuf power in 6 full swings to give a decent pulse, il be trying this soon,

  • Thank u 4 posting this! I was looking at my grampa's clock and wondering if this could b done.

  • Interesting idea! You might want to look into the CSD (Continuous Slip Drive) mechanism which allows you to drive the wheel on both strokes. You could do the same thing, of course, by adding another overunning clutch and chain but it's difficult to get the chain to cross so it drives the opposite direction. Easier with a rope.
