Fermi is my favorite. Don't ask. Einstein did not invent DC nor did Tesla invent AC. Both of these inventors discovered things that occur in the  universe regardless of human intervention. What they "invented" were the means for humans to harness this power. BTW H2 is flamable only in the presence of O.

Dude - Tesla invented the entire mechanism, turbine and coil etc to make AC, then developed transformers to amplify the voltage etc etc and overhead lines to transmit it 1000's of miles with virtually no loss. BTW there is no AC in nature, lightning bolt is DC ... as was publicised by edison as a safe electricity. BTW he electrocuted elephants in a TV ad with AC and he called it westinghoused.
Cool.

and tesla invented teh ways for teh buddha to whore gs parts 

The human nervous system operates on an AC current.

Ha ha ... near about certain no one knew that when tesla was around.
Cool.

I am pretty sure they didn't. I think Tesla was a genius, I was just stating that man didn't "invent" AC/DC current.
