Moller is a blowhard.  He's been promising flying cards 'in just a few years' since before I was born.
His current rotary beast has been flying around on tethers for over a decade now, with no real sign of 'taking off' anytime soon.
I'd love to see his car succeed, but...  there's a point where you stop listening.  He's like a reverse chicken little, except he never falls into the sky.
