Technology Features

Mainspring’s linear generator is designed to enable high expansion of reacted gases and to electrically control the conversion of linear motion directly into electricity. High expansion allows for maximum extraction of reaction energy, and direct conversion eliminates mechanical losses — combining to enable high efficiency operation across all power output levels from 0 to 100%.

Mainspring’s linear generator uses a low-temperature, uniform reaction that maintains peak temperatures below the levels in which NOx forms (1500°C), resulting in near-zero NOx emissions. This is in contrast to the burning of a fuel with a flame, which creates high temperatures and high NOx emissions.

Mainspring’s linear generator technology continuously adjusts compression and expansion, allowing it to dynamically adjust for varying fuel quality and different types of fuels, including renewable fuels such as biogas, green ammonia, and green hydrogen.

Mainspring’s linear generators match power output with building demand while integrating with onsite solar and energy storage, enabling the continued rapid adoption of renewables. In addition, Mainspring’s technology provides power when the grid is down, making it the ideal backbone of any renewable microgrid.

Mainspring’s linear generator is made out of standard materials with only two moving parts and operates without the use of oil or expensive fuel cell catalysts or complex engine mechanical systems — resulting in low capital and maintenance costs.

Mainspring’s linear generator products combine grid-tie inverters and auxiliaries into turn-key packages for fast and simple installation. Designed for commercial businesses, Mainspring's first product is packaged in a standard 20’ container.
