Onsite linear generators for scalable power
Mainspring Energy designs and ships onsite linear generators that produce electricity for commercial and industrial customers, data centers, utilities, and microgrids. The kit uses a straight-line motion that is converted into electric current by magnets moving through copper coils, driven by a flameless, low-temperature air-and-fuel reaction with only two moving parts and an oil-free air-bearing. The system is fuel-flexible, handling natural gas, biogas, hydrogen, ammonia, and propane, and it scales from about 250 kW to more than 100 MW, with near-zero NOx and no after-treatment required. The company sells power as a service, enabling installations with no upfront cost and ongoing payments based on energy use, aiming to lower operating costs and increase energy resilience for its customers.
