"brilliant or wacky"

The Hyperloop transportation scheme proposed by billionaire entrepreneur Elon Musk has created quite a stir in transportation circles. But Musk is hardly the first to turn heads with a transport idea that's either brilliant or wacky.

Ever since man first dreamed of flight, humans have been trying to come up with a better way of getting from point A to point B.

While some of the efforts were more creative than practical, all of them highlight the power of the human imagination to lift our spirits — even if they don't always keep them aloft.
