Firth Spring Engine & Car
The Firth Spring Engine is a revolutionary mechanical propulsion system that harnesses compressed spring energy amplified through a kinetic feedback loop to generate continuous rotational force. Unlike combustion or electric motors, the Firth Spring Engine stores mechanical energy in a series of ultra-high-tension titanium coil springs, releasing it through a patented staged-release gear system that multiplies torque output. The Firth Spring Car integrates this engine into a sleek aerodynamic vehicle chassis designed for zero-emission urban and highway travel. The car features regenerative spring recharging on braking and downhill travel, automatically re-tensioning the spring array without external energy input. With no batteries, no fuel, and no emissions, the Firth Spring Car represents a new category of clean mechanical transportation.
