Thomas Edison championed the DC power grid, which initially fed electrical energy into the factories to power these mammoth motors. The DC motor was coveted for use because its speed and direction could be easily […]

They are lighter than conventional batteries, providing a power-to-weight ratio that is much higher.  Their development has led to power electric cars. We will use them to power the Evergreen State. The Evergreen State will be using a battery system that has been developed to mitigate […]
