DIY magnetic induction water heater

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!

Interesting... I wonder why he chose magnetic induction as the heating method. It must have some advantage, but I can't find out because the video keeps interrupting (probably an interaction between my ad blocker and YouTube's ad blocker blocker).

Myself, I use resistive heaters straight off low voltage DC.

I think because it's somewhat novel, and really very simple. Once you start getting into electrical energy, you add layers of complexity. Think like global supply chains are going to get disrupted, and this kind of low tech is absolutely the right direction to be following imo.

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.

...that's like comparing every tool in a toolbox to like a ratchet and saying anything simpler is useless.
