It’s called Stella Juva. On a sunny day, it can travel up to 444 miles using nothing but the solar panels built into its roof. Instead of driving patients to a hospital like a normal ambulance, Stella Juva brings the hospital to the patient. They also previously built a solar-powered camper van and an off-road solar vehicle that crossed more than 600 miles of Moroccan desert. There’s no word yet on when, or if, Stella Juva will move beyond testing into everyday use.
