Hoverboard
We’re talking about a real hoverboard here, not Hendo’s hoverboard, which requires a specialized surface to hover. In BTTF II, the hoverboard Marty borrows from a young girl works on any surface except water. How far away is that? Frey is firmly noncommittal. “Ten years, 20 years, who knows?” he says. He’s not so quick to discount Hendo’s innovation, though, saying, “It’s an interesting breakthrough in thinking that dramatically brings a BTTF II–type device much closer.”
