The human power output to the bike is the product of pedal velocity and pedal force. The power output curve is, therefore, peaked over some optimal muscle-flexing range that is related to the velocity ...

Consider, for example, an ancient galley ship with many oarsmen providing an engine. This wasn’t a great use of human power. An oarsman on a galley used his arms and back but didn’t much use ...

Solving the three fundamental design problems inherent in a human-powered helicopter requires extraordinary ingenuity. The design must maximize lift. With the low-power engine, small, high-speed ...
