How about flying cars?
I've always thought a great idea for a flying car was a van-like vehicle that is either filled with helium or a vacuum, maybe a combination.
A blimp-like vehicle that won't deflate or leak would be even better since it won't need lift to stay up and wouldn't require much power to propel.
- galaxyLogic 13y agoThat's the point! We don't need materials that are lighter than Helium. We we need nano-materials that are strong enough to keep the vacuum in. Thanks ...
