The HumanCar is an arrangement of mechanical parts that convert oscillatory motion into rotational motion about one axis. Simultaneously, it converts oscillatory motion about another axis into oscillatory motion about an axis connected to a reference frame.
The energy available from multiple human beings is converted by the mechanism into rotational power creating useful work, such as to propel a wheeled frame capable of supporting the mechanism and its occupants. A bi-directional power interface allows occupants to face forward or backward or in any combination. If each pair of occupants is placed back-to-back, and each adjacent pair is caused to create a controlled torque about a crankshaft, then power pulses may be balanced as much as possible about the crank shaft. The leaning motion from one or more occupants controls direction through a system of connecting members.
Participants may all face forward or backward or in any combination. If each pair of occupants is placed back-to-back, and each adjacent pair is caused to create rotational power pulses which are balanced as much as possible about the crank shaft, then the most efficient use of the mechanism may be obtained."
Version one proves it's possible. The giant benefit that results is a singular plyometric exercise that does not exist outside of this platform. The HumanCar is based upon original technology that has deep roots in automotive technology. The vehicle shown is of similar concept, with an aircraft quality steel tube 'space-frame' chassis, all hand built. This vehicle is very fast, and handles great. The HumanCar has proven to be the same."
