I can’t speak for them, but cars and EVs in particular have their issues. And I say this as an EV owner. The biggest issue I have is battery volatility and the trouble of putting out an EV if they catch fire, which generally seems to be mostly a risk in higher speed collisions. It’s a huge infrastructure hurdle for our firefighters.
That being said, necessity breeds innovation, the more common EVs become, the more people that will be working on a solution.
Competition from Chinese EVs are only going to be a good thing for American buyers. Why the hell are most longer range EVs $40k or more after incentives? Lack of options and lack of competition is my bet. And if you’re worried about cheap labor and materials being unfair competition I have bad news, American brands also build their cars in Mexico and purchase materials from dubious sources.
As you said, friction would introduce more wear and maintenance. This gentleman’s idea is to attach a windmill to drive the rotary induction wheel, which would essentially be “free” heat energy, and an interesting hobby contraption. Entertainment and a sense of accomplishment is probably his main goal.
Its not a brand new idea, just a different application of the principle. Induction generators already exist, and they can indeed be used with windmills, but to generate AC current versus heat energy.
More power to this fun and crazy inventor. Maybe he can find practical and reproducible use for this effect. If not, he’s gonna have the most unique water heater ever invented. With this he could make a fully mechanical hot water heater that burns no fuel and uses no electricity. He would just have to make a mechanism to disengage a clutch at the top temperature.
