Vehicle: Catapult
Traveling Trampoline   (+9, -2)  [vote for, against]
With ropes, pulleys, wheels and regenerative braking

“…and this trampoline was about a meter in diameter and mounted on wheels. I couldn’t bounce very high ‘cause half of the jump energy was converted to driving the wheels. Steering was accomplished by jumping near the edge in the direction you wanted it to roll.

I wasn’t doing too well on the sidewalk. I remember a bicycle swerving around me and an old lady shaking a cane. I was passed by someone athletic doing flips on a speeding traveling trampoline. Hopping at the rear edge stopped me at the corner, and the braking energy sent me springing high into the air until the light changed. So, what do you make of my dream, Doctor?”

trampolines are scary. Our coaches refuse to compete on tramp because they are so dangerous. My son's gym team watched as a kid fell on concrete floor at a meet. He died in the hospital. That is why I shudder at this idea, it is more like a bad dream. sorry fj, just had to share that story.

but to anyone else it probably sounds like good wild fun.

We have a number of kids injured on rented lawn trampolines here, but nobody dies in my halfbaked ideas or dreams.

But you can have a harness which keeps you in the boundaries, and build it so that the center of gravity wont let it overturn. This is a GREAT idea!
