At 70mph most energy is lost to wind resistance.

EVs are also heavier, which increases rolling resistance on the tires. This lead to the formulation of stiffer tires for EVs to counteract that effect.

Last time i looked into MOND it remains relatively unconvincing. The primary reason for this being that it is hard to make the universe look like it should with simulations. We are doing better so far with the lambda-CDM model so far.

If someone comes up with a MOND simulation that is better than our current ones it may gain more traction.

I'm not an armchair physicist, I'm actively working on my PhD in Physics.

Dark matter is the prevailing theory because it best explains our current observations. I'm aware that doesn't mean its right, and we don't have conclusive proof that it is.

There's definitely a problem with our current model looking at the Hubble tension, but the reason for that is still unknown.

So I love when armchair physicists come in and say dark matter is obviously wrong.

Salt deposit clog the devices, harvesting the salt sould require labor. Rejecting the salt allows the device to run passively for years.

Further concentrated salt solutions deposit in the device, clogging it causing it to not work. You could harvest the salt, but then it is no longer passive.

Almost certainly the opposite. More massive galaxies tend to form in more massive dark matter halos.
