No pistons, no cylinders, no logic: This engine is so futuristic that it shouldn’t even run

Yes, momentum and gravity. Except no one can explain gravity yet

Newton explained it nearly 350 years ago. Einstein gave us a new way to look at it, but it’s pretty well understood at this point.

Looks like another attempt to round up some investor money.

These things pop up over the years almost like clockwork, then disappear only to re-emerge few years down the line.

I would guess certainly true for some , probably many.
I just happened to keep seeing stories about lots of that type of R&D that is supposed to be going on in Israel these days. Not sure what, if anything they have accomplished yet. There has been very little proof they have been successful with any of those things. We can always hope and dream from something better one day. Yet I still like my ICE vehicles.

Understood what it does - sure. How it actually works - no one knows. Relativity does not line up with actual quantum mechanics regarding gravity. So which is wrong?

“Nano materials” has a familiar ring to it…almost like “crystal lattice pressure” from “cold fusion”.

Though, I believe Pons and Fleischman were genuine in reporting their findings. They truly believed that they had seen something that changed our understanding laws of physics, and offered new sources of energy.

Sadly, they were wrong.

Gravity is easy, FYI it involves elephants.

"Does not line up" is a small use case. It lines up just fine for everything we need it to do for things like space flight, and all of our observations support the current understanding, including relativistic phenomena like gravitational lensing.

But in the case of gravity and quantum mechanics near black holes, singularities, there are some issues to be resolved.

As far as "how" - that is philosophy or meta-physics - "how" does electricity "know" where to flow? "How" do electrons "know" where they are supposed to exist in quantum mechanical states?

The "how" is unimportant - it's enough to know "what" it does.

Relative to this thread that is like saying my wife knows how to operate a car - but has no clue how to open the hood, and has only put gas in it once in 26 years of being married (and boy did I hear about it).

That’s not the analogy I would use.

It is more like saying that your wife knows every component, how the pistons are shaped, what alloy they used, how the rings are made, how the oil functions, and she’s read the entire owners manual, but she’s not sure why they chose the design elements they did for the styling, or why it’s a 3.0 liter instead of a 2.2

I am paraphrasing, so give me some rope.

Question - why do the planets circle the sun - answer - gravity

Vs - Question - how does a compressed air car work - answer - the force of compressed air.

There the same. Both true. We know how both forces behave. But it really doesn't answer either of the "why" questions.

This thread brought up my thoughts on the various internal combustion engines that supposedly have an advantage in efficiency. Just about every option has been tried. In the end, the piston engine rules supreme due to a combination of power, reliability and efficiency. Just to be clear, at the temperatures and pressures we deal with, the Carnot limit for engines hovers in the 80% range, minus heat transfer (waste) and friction, along with some difficulty extracting all the energy. (remember your thermodynamic teacher talking about the Furnace and Sink and how those temperatures limit efficiency)

The best we can do in reasonably sized engines has been calculated at 54% thermal efficiency. Any way you slice it, it takes HP to move a car or truck.

Atoms? I have no idea what you mean by planets that “spin” around atoms, unless you mean electrons, which aren’t exactly spinning. IF you have disproved quantum mechanics - I am sure the scientific world would be fascinated by your findings.

Quantum Mechanics , just like all SCIENCE, it is not a fact, as new things are always learned, just like the science of old, where they thought the basic elements were, Fire, Water, Earth and Air, and I suppose if you questioned that back in the day you were laughed at and ridiculed (like I am all the time on here), and or burned at the stake.

And oh, I found this article just now, not before posting what I did the other day.
