Extra Speed Englishlads James Nichols Getting A Hand Pumping A Big Toy [patched] Fulll Link Guide

The calculated energy input (≈ 68 J per pump) is comparable to the energy a cyclist would generate over a few seconds of moderate effort. This demonstrates that a fit adult can indeed impart “extra speed” to a non‑motorized vehicle using only arm power, provided the mechanical design maximizes energy transfer.

The case of James Nichols illustrates how simple physics concepts (gear reduction, energy storage, and human biomechanics) can be packaged into an entertaining, viral format that both educates and amazes. The calculated energy input (≈ 68 J per
