R&D

Leveraged Gravity is an investigation into the geometry of torque transfer.

A lever rotating through 180° under gravity produces a sinusoidal torque profile with a mean mechanical advantage of 2/π ≈ 0.637 — the same constant that appears in rectified AC waveforms and Buffon's Needle experiment. Most machines fight this variation. This one is shaped to it.

A variable-radius spiral winding sheave (red in the model below), cut to match the sine profile at a 1:4 ratio, transferred energy between two equal masses at a measured 98.6% efficiency — on a plywood-and-screws prototype. March 2022: 57.7 cm of input descent produced 56.9 cm of output lift. The missing 1.4% is friction.

No energy is created here — conservation is exactly the point. The result is near-lossless transfer achieved through geometric impedance matching alone: no precision bearings, no springs, no external power. Classical mechanics. Measured. Reproducible.
