I have an old kitchen and do not want to redo the wiring inside the walls. Also, I don't want ugly electric wires outside. The solution is a few laser beams that fill a battery. Even if any of the beams get cut off by an interfering object, nothing happens, because these are low-power beams.

Most appliances today do not take much power. Especially LED light fixtures.

no A1. Neither.

..."and can potentially charge a smartphone as quickly as a standard USB cable."

I'm not talking about a mobile charger. I'm talking about stationary light fixtures far from the outlets on the wall.

I can charge them throughout the daytime. As opposed to the phone charger, my beams will be low power each, but coming together at the target quite some energy could be gathered. Maybe even enough to power a phone battery charger for some time.

..."as well as a reflector-based mechanism to shut off the laser if a person tries to move in the charging beam's path."

- of course no need for that with my device.
