I think lasers are pretty wack when you think about them through this lens. A small, wand-like object in your hand can make light appear from seemingly nowhere. If it’s powerful enough it can set things on fire or blind people. Not to mention larger ones like laser cutters or the LLD, used to destroy missiles midflight. Thats sure to blow some feudal peasant minds
I read somewhere that we are going to set up solar panels in space convert the electcity to radio radios, beam it to earth, then convert it back to electricty.
To anyone that wasn’t Nikola tesla, that just sounds insane.
Nah, that’s not an actual plan that’s being implemented. It’s basically a thought experiment at this point. The problem with wireless energy transfer at that scale is that it takes a fuck ton of output power to generate a little bit of input power at a distance (inverse square law)
Correction. It actually has been done.. A prototype has successfully demonstrated proof of concept.
You are right about the efficiency, but since the amount of energy that can be gathered in orbit is so large, the small fraction that can be received on Earth could still be significant.
Yeah, a proof of concept is one thing, but scaling it up to deliver mega or gigawatts is a whole different beast. I’d be concerned about environmental impact with radio waves that strong.
I’ve already done that in Dyson Sphere Program though
