Another outside-the-box approach to transport that deserves a place in our top 10 is the Shweeb. This human powered monorail system uses bicycle pods suspended from tracks to create a very efficient option for getting from A to B.
Currently you can ride the Shweeb at the Agroventures in New Zealand where you can reach speeds of up to 45 km/h (28 mph) under your own steam. The idea is not limited to adventure parks though. Shweeb picked up a US$1 million investment from Google in 2010 as part of Project 10^100 and the company says it will soon be announcing the planned location of the first Shweeb built for public use.
