The Stella is an impressive car. I did read the specs, though not carefully. The fault is my assumption that climbing, say, 1000m would take too much energy. In fact, the climbing by itself probably would take between 1 and 2kwh. That leaves plenty. Wow ! Peri -- Original Message --

Peri I doubt you have completely looked at the specs of the Stella cars.  They have huge trunks and are touted as "Family Cars" basically a small SUV.  They use a 15kw battery which without solar has a 400 mile range.  So they would charge quickly just on Chademo or CCS.  Just because a car is

The mid-range (260 miles) Model 3 is indeed available, but it is $45,000. They count on the $7,500 federal tax break and state incentives to make it a $35,000 car. The long range Model 3 can currently be bought for about $49,000 with federal and state incentives then reducing that price. As I am

ALL EV's are predominantly charged while parked. Solar panels on EV's are not for propulsion power but for battery charging during the 8 to 16 hour solar day while parked in the sun, not just the 30 minutes the car is in use. This is for those without a dedicated charger at home. Bob
