  • I wonder what the friction comparison of the ferrofluid vs a graphite piston would be, and whether the ferrofluid would eventually let all the oil drip out and become a crunchy bit of iron filings stuck to a magnet.

  • check and refill once a month

  • am i right in thinking this doesnt need no power-energy? so therefore could answer our worlds energy sources?

  • No no! It is a Stirling motor.

  • I like the redbulls, nice work 5 stars

  • Thank You!

    It began to produce power.

  • ...you mean apart from the electric cooker it's sitting on top of? :)

  • @pariahthewanderer NO dude, actualy watch the vid man its on a STOVE TOP, and read the FIRST and SECOND LAW OF THERMAL DYNAMICS.energy can not be created nor distroyed only change form,and energy always moves in an ordered state to a non ordered state. also READ on Sterling motors they DO work on heat and that is there "fuel". they symply step in that energy "line" and Harness it to convert it into "Work".

  • This is how Redbull gets energy in their drinks....

  • will the thing stir forever?

  • @traubthegreat A Stirling engine of this general design works by changing the temperature and pressure of a gas (usually air) sealed inside it. In short, if you heat one side of the "pancake" at the bottom of the engine and cool the other (really doesn't matter which), it will turn.

  • Explain to me why and what is going on? Cool as hell though

  • @kruegda No, they need a magnetic field, which can be provided by a magnet. No juice required. To make the standing temperature differential for the Sterling motor to work would require some sort of fuel. This wouldn't be a bad way to build a geothermal power plant, once it was scaled up and re-engineered appropriately, but that would still be using a limited resource.

  • Free Energy
