Overview

Mainspring was founded in 2010 by three Stanford engineers seeking a new approach to generating clean, resilient, affordable electricity. Their research into high-efficiency methods of converting fuel to electricity led to the founding of the company and the development and prototype of their first linear generator. They also built a culture of collaboration and innovation.
