Maybe not water-skating power, but power nonetheless. In support of the Michael J. Fox Parkinson's Foundation, ZBoard has launched a one-time-only campaign. What do you get? Marty McFly's hoverboard from Back to the Future II. Well, something that looks damn close to it. At $1,500 a piece, these run steep, but you'll have one of 25 Zboard Hoverboards made. And for $200 they'll send you a replica board without the electric elements.
