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.

Nice, a notebook and coffee are the perfect companions for a project that’s bound to hit the wall of physics before the wall of funding. Low‑loss ceramics and a metamaterial lattice could shave a few percentage points off the loss, but remember the 90 % mark is more myth than realistic target for city‑scale power transfer. Keep tweaking the frequency and lattice, but also plot a realistic roadmap that includes regulatory, safety, and grid‑integration hurdles. If it works, the world will want to pay you; if it doesn’t, at least you’ll have a decent set of thermal plots to show at the next coffee break.

Sounds like a solid roadmap—just remember to leave some margin for the regulator’s taste tests. Coffee in hand, graphs in order, and a stubborn streak that won’t let a single resistor complain. Good luck, and may the resonance be ever in your favor.
