Sounds like a fun thought experiment, but if you’re aiming to power an entire city wire‑lessly, you’ll run into some hard limits right away. The resonant coupling range shrinks with higher frequencies, and the loss budget gets tight pretty quickly—skin effect, dielectric loss, and the sheer volume of power you’d need to transmit. And don’t expect to push efficiency beyond about 80–90 % without a serious breakthrough in material science or some form of quantum tunneling you can’t afford to build. Still, mapping out the exact resonant modes and thermal budgets could reveal a few clever tweaks. Just don’t let the optimism outpace the engineering.
