Solartaxi visits AeroVironment

Revenge of the Electric Car

Solartaxi just extracts that greenly produced electrical energy from the grid while touring the world. Solartaxi has two Swiss made 14kwhr Zebra batteries which are a molten-salt type battery that has an operating temperature window of 270-350degC (518-662degF). Zebra batteries have an energy density of around 90Whr/kg. That gives a cummulative energy storage capacity of 28kWhrs. Stefano readies for a Solartaxi test drive.
