People can fly among the trees like birds. What you think about this?

People can fly among the trees like birds. This is not a dream but a reality. It is ecotourism of future. To achieve this goal, people just should slowly rotate the pedals, like on bicycle. The tourist hanging rail line consists of a rail, suspended between tree trunks and "cabins", roll along the rails, where tourists sit comfortably. In the “cabin” tourist rotates the pedal that connected to an electric generator. Generated electrical energy allows "cabins" to move up and down, besides moving forward.

Ahh! an interesting concept.. but why do we need to travel only through trees when we can travel throughout the world..

the world is getting smaller by the advent of technology and the internet.. people can go anywhere at this period in time using different modes of travel..
