Here is the future of the green amusement park: The Skycycle at Washuzan Highland Park in Okayama, a pedal-powered roller coaster. They clearly have some dramatic topography to take advantage of here, and it looks truly frightening. Most North American amusement parks are on pretty flat terrain but they often build artificial mountains- Demand a green ride like this on the Magic Mountain.
The side-by-side tandem pedal-powered carts have seat belts, and a cute pink basket.

off you go
this looks really scary...
I think I may have made a mistake....
OMG I have to go on THAT?
UPDATE: No, as commenters pointed out and I missed, that is a separate roller coaster. If you
check out the additional pictures link at the bottom you will see this more clearly.
this is evidently known as "the third corner of fear!"
pretty spectacular view of the Shimotsui-Seto Bridge in the background.
