Well, that's the energy crisis solved...

And completely CO2 neutral too, just some noise ...

  • @pilF idea from this video at 1m30s - I'm never sure if these guys actually think we believe that perpetual motion is possible, or if they just want a million hits to earn $$$ from YouTube's monetization.

     

    My scene has angular springs to keep the spheres in the mid position and each has its own gravity. The springs + gravity are rangemapped to get the movement. The rotation is from a motor and the collision bumps it a bit.

     

    Here's the file if you're into XPresso. The blue helix springs are disabled (via control null) to speed up viewport

    Hey thanks for the scene Jed, I guess they know it does not work. The video is cut three times in the first 2 minutes. Just to give the appearance op continuity. If you paid attention at school you'd know energy does not appear from nothing (only complete universes do)

  • @pilF I've made a few perpetual motion machines that I've seen on YT eg

    actually very relaxing to look at. Wouldn't these be nice to use in science class and find the flaws. As a vaccine against desinformation.... Oh wait, a vaccine, that wouldn't work on believers.

    The unbalanced wheel type of PMM goes back to Leonardo da Vinci, and whilst fun to build in C4D, IRL they are all doomed to failure due to friction and the 1st law of thermodynamics 'energy cannot be created or destroyed'. When I have built such wheels in Cinema, they tend to jiggle for about 1 sec and then attain a state of equilibrium - they don't rotate forever 'under their own steam' - you always need a motor, keyframes or XPresso. Whilst C4D dynamics is only a simulation, I imagine these PMM wheels would do the same IRL.

     

    I'm quite impressed at how C4D can solve quite complex dynamic situations (see my other posts about logarithmic spiral gears) and copying (pretend) PMMs seen on YouTube is a great way for beginners to learn about C4D motors, springs, connectors etc.

     

    It bothers me that fake PMMs can get 10 million hits on YT and generate cash rewards for the posters. As with flat earth videos, YT seems to think promoting bad science is a good business to be in.

    At least every single one of those videos has a vast army of sceptics in the comments to painstakingly explain to the GP why it doesn't work 🙂and as you say, some of them are very pleasing to watch, perpetual or not...
