Hi.
I don’t think I would ever want to do this; its too risky, but simply because it interests me, I’m going to ask anyway.
Say I am in a valley, and the signal to my car radio is not very good, because of the sides of the valley blocking the signal (I don’t know if this actually happens, but never mind). So, I get my kite, and attach a really long piece of wire to it. Then, I send the kite up into the air, and it takes the piece of wire above the level of the hills, so that it can receive the radio signal (the wire is connected to where the aerial usually is). I don’t know if this would actually work, but again we’ll gloss over that for the moment.
However, stupidly, I don’t keep an eye on the weather, and a thunderstorm brews up, and my ‘aerial’ gets hit by lightning. The lightning streaks down my really long wire, and blows my radio to pieces, and quite possibly the current would jump to me (who is sitting near by), killing the radio and me. This would be slightly inconvenient.
How, then, do I protect it from this kind of high voltage. Could I put a high value resistor in the line, so that when a reasonable amount of current is drawn, a high voltage fuse would blow when the current reaches above a certain point?
Also, when the fuse blew, how would I prevent the current from trying to find another path to earth (probably me)?
Am I just talking complete and utter rubbish? Or is there a good way to do this?
Thanks
Tim
