I recall being on a field trip in DC as a kid and seeing some exhibit at the Smithsonian with similar physics, and at the time the thought in my mind was “no way in hell I’m getting on that.” My sentiments here echo those of my youth. It’s a roller coaster with cars you pedal. No, really. The green ride has carts on a track that are propelled by the people who ride in them. And that is all it is.

I salute the Japanese for throwing safety to the wind. If this is not proof that they have no Ralph Nader-San, I don’t know what is.
