Heavy wires/new wiring type

OK! so currently there is only one type of wire in SL. I suggest we have a new type of wires called Heavy wires. Instead of only being able to move about 50 power per second, they move 100-500 per second. This way you can get more power to shields and machines that use as lot of energy. Most likely you could use cobblestone wall as the item, or nether brick fence. Its up to whoever. I just think it would be very useful for bases/ships.
