The truth is, the entire Universe is made of electricity and we have only to learn how to harness it, motivate it, channel it. Don’t worry — it will come to us when we’re ready (just about now). Just as archeologists have, with some chagrin, had to retract their previous beliefs on how old intelligent man really is (millions, not thousands, of years), electrical science will have to retract on the Law of Conservation — it is simply not true. Or I should say, it “will no longer be true once the previously undiscovered energy types are discovered.” Wang, X., Peng, G., Wang, G.: The design of Halbach array permanent magnet for in-wheel motor[C]// electrical machines and systems (ICEMS), 2013 International Conference on. IEEE (2013) So, there’s a couple of angles to this. What you’re talking about is putting an inductor into a spinning magnetic field.

The problem being the difference in scales between 3.5mm & 4mm to the foot. Therefore a 3ft wheelset to HO standards (10.5mm), is much too small for OO (12mm), even if you could get one with the right spoke arrangements e.g. 8 spoke, being the most common British wagon wheel. Worse still the standard for US prototypes is that 33 inch is the most common size, thus making them extra small for OO.

The wold has done a HUGE amount of research on magnetics and electromechanical energy conversion – it’s extremely well-understood technology. Efficiency of energy conversion can be quite high for particular types of motors. But it is, and always will be, the case that energy must be put in before it can be taken out. Chen, T., Lyu, J., Wang, Q., et al.: Mechanistic study on boron attraction and isotopic separation with magnetic magnetite nanoparticles[J]. J. Mater. Sci. 56(7), 4624–4640 (2021) There are literally thousands of people out there in the world who have invented magnet devices which can rotate on their own power and thereby drive a generator without any help from external power sources. There are also people exploring plasma coil schemes which “induct” extra electrical current from the limitless potential we are swimming in. The use of these devices will be commonplace in 40 years — the need for a power “grid” and paying for energy will be obsolete.

This isn’t free energy though. That antenna will put a drag on the moon and if you made enough antennas and had them sipping power long enough, the moon would slowly stop spinning. It’s just that the amount of power behind the spinning of the moon is incomprehensible compared to what you’d be extracting, like stealing sand off the beach. You ARE depleting the beach, but who’s going to notice? If you do it every day for 80 years… eventually there’ll be a hole someone will notice. To all of you who see this and become excited over it: crafting your beliefs based on what you wish could be true is folly. Educate yourself.

Mechanical Research and Application V. 33 No.168(04):36–39 (2020) Mag wheels earned popularity on race cars for their lightweight properties and high durability. They were also seen on daily drivers, at least up until the 1960s, when aluminum alloy wheels became readily available. That is indeed the problem. I have some Kadee wheelsets here and they are considerably smaller that the UK versions; see the image below (Kadee on the left, Alan Gibson on the right):
