>> No, not exactly true.
>> For those who have never read it, the history of Nikolai Tesla is a
>> fascinating read
>> Tesla is credited as being the inventor of our AC power distribution
>> system
>> as we know it today, including 3 phase.
>> History claims Tesla drew this out in the sand one day on the beach
>> Tesla was a brilliant inventory but not a business man. Westinghouse saw
>> the
>> potential (no pun) of Tesla's inventions and provided the capital to make
>> it
>> happen.
>> Edison (General Electric), already well invested in dc power 
>> distribution,
>> attempted to dis-credit the AC power by references to the "deadly ac
>> power"
>> used in the electric chair executions in New York.
>> Although AC power grew became all it is to us today, Tesla died alone and
>> poor.
>> Fascinating stuff
