This person-powered bike in a bubble may be the next wave in personal transportation. Or, "personal trains-portation" as the company likes to call it. Shweeb just got a $1 million grant from Google's 10^100 invention contest to refine their idea into a workable urban transport system.
To power the Shweeb, the rider lies back in a recumbent bike position and pedals her way to work. The company even claims that the energy required to propel the Shweeb is less than it would take to walk, yet it propels you four times faster. The company is currently working out the logistical issues surrounding using the pods in a city.
