Sorry for the youtubes, I recommend Ytdlnis to view:

DIY magnetic induction water heater that uses no fuel, but instead uses free energy from sources like wind or water directly to create endless hot water.

Really impressive and simple concept with so few parts!

nice, but seems more complicated than Stirling, unless you have no pistons and lots of copper wire magnets. (edit: distracted writing, I'm watching it lol)

    ...what? a stirling engine turns heat into rotational energy, this one turns rotational energy into heat. they're entirely different machines.

    also this has *one* moving part, how is it more complicated?

    A Stirling engine is symmetric device that could work both ways.

    But I admit, after staring at this for a bit longer, it doesn't even really need any kind of special or even similar magnets. It is simpler indeed.

    so if you spin a stirling engine it produces heat? ...like from friction losses? couldn't you just rub two sticks together for the same effect then?

    yes i'm being facetious, i know you can use a stirling as a heat pump. but that just seemed even more complicated compared to this.

    Yeah, I just compare every lowtech to it, it's like a baseline anyone can make. Anything simpler is awesome, anything harder is useless usually.
