Climbing Air — An Open Engineering Notebook
A public engineering notebook exploring whether stored human energy can be transformed into useful aerodynamic motion.
Field notes
The project frames human-powered flight as an energy-delivery problem: accumulate low-power input, transform its timing and mechanical characteristics, then apply it aerodynamically. Its examples include whip-tip acceleration and stacked-ball impacts, while the next stated step is bench testing of force asymmetry, oscillating surfaces, and elastic transfer. The homepage identifies an earlier full-size PVC and umbrella apparatus but supplies no test data or flight demonstration.
