I don't know (and it's true... I really don't know) but I suspect much of what Tesla had going was not destroyed but removed from the public eye. If he did make the Pierce Arrow work from EM energy, the oil companies would have to shut it down for obvious reasons. I still think there's enough evidence out there to substantiate the electric car story (I'll keep digging). There are other examples out there of technologies that worked very well, yet never came to fruition. Dr. Royal Rife's 'Rife Machine' was capable of treating tons of ailments, but Big Pharma shut that thing down in a hurry because it threatened their emerging industry. We live in a greed-based world where money takes precedence over practicability (no newsflash there). It's no stretch for me at least, to believe many great ideas have been squelch over money.

Live to love, love to live.
