Two points to ponder - and keep in mind, I am a pessimist by way of constant disappointment...
1.) To all those who think the engine hasn't run - someone has mentioned that it "has produced more [hp] than anticipated" (not an exact quote, but from memory) - so it must have run... and, of course, been built.
2.) PE does not want to sell interest in EM. Selling would be a great way to get "scam" money, holding ownership only makes him the big bucks if the Elio sells and sells big.
Make of this what you wish, to me it means EM is working hard to get a product to market.
