The kid didn't invent anything either, sorry to say. We're surrounded by energy in the form of light, radio, wifi, etc. You already know its possible to capture it, but capturing enough so you can power things is expensive.
A Crystal radio works the same way. You're surrounded by enough radio energy to actually hear it with a radio with no external power. A long antenna, a coil with a tap, a capacitor, a diode, a transformer, an earphone and a ground is all you need. (Yes I used to build them too! Fun!)

You are wrong here. Course radio waves that surround us can be easily turned into electricity by just a 20 meter wire. It will be enough even to lite a small lamp (ok, a diode). But this is a very different kind of power. Not human-made one. The Earth is a
HUGE electrical engine. It has a rotor and a stater (you should be learning this scheme in the school). So it does generate a mad power. When I say mad, i mean something which is really
MAD which can't be produced by humans using all the existing resources and technologies.. Even nuclear energy is nothing comparing to that our planet generates every millisecond.
So when all those "tesla" generators (there are many types of them) take the electricity from "nowhere" (it's not so of course). They take it from our planet. The theoretically no energy can be only in absolutely vacuum, with absolute zero temperature and a zero gravity. In a place where even the time doesn't exist. But it's just a theory. Practically we know it is possible to get an absolutely incredible power and mass(!) from literally nothing. E=mc^2 - it's a formula of the Universe. 99.99999% of people says "ah I know it! Einstein has invented that formula!" They really know it. They know Einstein, but they have no idea what exactly it does mean.
