This was an idea generated by my sister that I thought was very interesting. I intended to make it work by strapping rollerblades on a person's legs and utilize a compressed gas/steam-powered pumping device that would be worn on the back of the character. A gas pumper would push the character forward at high speed (kind of like a rocket backpack) while the rollerblades could be used for directional control. These two are connected to each other with wires and are worn like a suit. There should be something balancing weight (or do you have suggestions?) to keep the character balanced while moving.
Is it possible? If not then how can I improve it? Are there any similar alternatives?
