This is the fastest road vehicle in the world, the Acabion from designer Peter Maskus. It can go up to 342 mph and gets about 70 miles per gallon at 60 mph. I found it on Kanye West's blog, where he posts futuristic (and super-expensive) toys almost every day. One day, it'll be a self-cleaning kitchen that uses plants developed by the aerospace industry that produce water and vegetable soap. Another day, it'll be an e-paper bracelet that can serve as a watch, or a multimedia player. Or a mobile bubble workstation. Or a jetpack. It makes sense, since Kanye's summer tour will be "set in the future." Click through for a gallery of Kanye's futuristic toys.
