Until and unless it is proven this 'helicopter' flies and can be controlled, it is nothing but a toy. I hope the government does not allow it to fly near people or houses because it is destined to fail. Maybe future models can be improved but this first one, I am highly doubtful.

You can buy a helicopter for $21,000 in ebay http://cgi.ebay.com/ebaymotors/BELL-OH-58-HELICOPTER-21-500-ACCEPTING-OFFERS-/120928792775?pt=Motors_Aircraft&hash=item1c27eaf0c7

It's cheaper than and looks more rigid than what that guy is asking for his tin can invention.
