This discussion remids me of an article I once read, many, many years ago, about Burt Rutan, the intrepid aircraft designer, about simple concepts. He had probably the most brilliant and innovative aircraft designs ever, and could explain them quickly and simply. At one point, I remember him saying that anything that took hours on a Cray to work out, probably wasn't meant to be.
There's also a philosophy - I forget the name, but something like "Achmed's knife", that goes something like: "The simplest explanation is usually the correct one". So, if there isn't a simple explanation, it's probably "B.S."......

Pelmear's claims of putting electromagnets and permanent magnets at various locations in an engine are bogus. He has never built such an engine. The electromagnets that he shows in his patent figures are purely figments of his imagination. If somebody actually put those electromagnets in a real engine, they would not generate enough force to even turn the engine over, much less do useful work.
I do know a thing or two about electromagnets. I designed the electromagnets shown in my patent #6,389,941 for 1600 lbs peak force, and they actually did deliver that much force.
Pelmear's electromagnetic engine is nothing more than hot air. His skip fire, on the other hand, is just a fast acting fuel injector kill switch. I could accomplish the same result in my truck by planting the gas pedal on the floor, and controlling speed by pulsing the kill switch.

We can simplify the entire electromagnet concept down to this: It is just an electric motor connected to an ICE without a coupler or belt (or gear, etc.) drive. IF it worked at all, it would only save the <1% of transmission losses... but then due to it's ridiculous layout it would surely be >1% less efficient than an electric motor.

Of course, the more of it I read, the more striking I noticed the irony of having pages and pages trying to explain why the simplest explanation is usually the best!!!!

Occum's razor should then be excluded?

It's funny. And I've seen it before - someone trying to appear smart using some crazy convoluted route to explain a simple concept. What I especially like is when, in a group, someone does that, and then someone else (who actually is smart) clarifies it with one or two straightforward sentences.

Then you're the guy who could answer this: don't rare earth magnets have a really sharp drop off of effectiveness at some critical temperature? And that critical temperature isn't all that hot.
Just as a f'rinstance, like a not-too-exotic N45 neodymium, the critical temp is...what?
[looks up "Curie temperature"]
Okay, never mind. Inside the engine is hot, but not THAT hot.

Which is the beauty of this forum, everyone is just picking it apart - like chefs looking for meat in a vegetarian salad.
No meat here. Just meat flavoring.

Full disclosure: I didn't bother to look at the patent, because I enjoy my life. That said, everything everyone on this thread has written makes me think this is a more convoluted and less efficient version of Honda's IMA hybrid system.
