The Mainspring Linear Generator delivers an unmatched level of flexibility for the transition ahead. It&rsquo;s local so you can site where power is needed, it&rsquo;s dispatchable so you can ramp up and down to complement renewables, and it&rsquo;s fuel-flexible so you can operate on the cleanest fuels available today and in the future. Our products are already at work at Fortune 500 customer sites, accelerating the arrival of the net-zero carbon grid.
