Based on very little research I have an idea how tesla coils work and if you're able to create electricity out of the free flowing electrons from Earth and we already have a capacitor inside of the coil then what is keeping us from attaching an output and using the coil as a voltage source? Its my understanding that the coil ramps up the voltage to around 10,000 V to create the arcs of lightning. Why can't we use less rotations of the coil inside to ramp the voltage up to a safer level then us connect it to various electronic equipment that would then ramp down the voltage to a usable level? I know this could be a dumb question because if it could have been done then someone long ago would have made it possible but I'm just having a tough time understand why it isn't possible. Thanks guys!
