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.
I’ve already done that in Dyson Sphere Program though
