Magic Busted

Oh man, this thing is sweet. Can you imagine driving through Baja in it, pulling up to an empty point break and just disappearing for a few days? Well, you'll have to. The Westfalia Verdier Solar Power vehicle (or the Magic Bus) still doesn't exist. Perchance, to dream...

Can you think of any other amazing ideas/concepts/inventions that never came into being? Flying cars, perhaps?
