Stupid movement. Redistributing wealth doesn't reduce emissions because the poor will spend the money just as the rich; only they can't afford EVs.

As I've said, the two most viable ways to reduce emissions are:

1. Reduce population
2. Reduce wealth (for everyone)

I suppose redistribution of wealth actually accomplishes #2, because countries that do this are among the poorest in the world.

It's great that places like France exist, so that we can feel fortunate we don't have to live there.

Besides, for heavy cars with poor aerodynamic, I believe not all homes would have space/rood area for solar power for home use plus heavy vehicles use.
The STELLA car is amazing, but it is waaaay too expensive: the two super efficient hub motors cost about $30k each.

Most homes can have much more than 900-1000 watts of solar, which is what is on the STELLA car - and on a building, solar panels can be MUCH more productive, because they are fixed. On the car, they would be in shadow a lot of the time.

Low weight and low dragh helps reduce energy used. Lower energy lower thermoelectric activity. Lower energy consume means less battery pack.
Solar panel on the vehicle also reduces the need of a lot of batteries.

The solar output, for home, matters if you think in reduce fossil fuel use.

Doesn't matter if the solar output is enough because you connect the house to the grid.

If you missed my point somehow, I'll just tell you. Putting solar on the roof of a vehicle is beyond retarded.

In The Twilight Zone maybe there is a universe/dimention where only rich people destroys the environment. So Tesla have a great idea for such paralell universe.



Stella it's low weight and aerodynamic. If was as a usual car it would require 4x more electric energy. So you must consider as 3600W of extra solar panels for home.
Yes, it's expensive, but there is a Indian solar home car project much more affordable. Good efficient motor but not the best, but good enought (a bit more than 90% but not 98%)

The own solar panels on car also reduze the need of many battery packs, and so reduces the weight of the car.

Once again, how much does that weigh?

I live in one of these, I won't be posting pictures of my own example.

If money weren't an problem, I'd make one of these. Flexible panels could lay over the dihedral angles.



Back on topic.

Low drag isn't so important in a vehicle designed to be driven locally, at slower speeds, as a commuter and grocery getter.

Solar doesn't reduce battery size requirements at all.

Solar belongs on a roof or dedicated stationary structure, not objects that move about the environment.

If solar is cheap, light and robust enough to apply to the roof of an EV - why not? It can help keep the car cool in summer, it can prevent bricking the battery when the car isn't used for a long time. But it won't have a big effect on range.
Yet, any help, however small, is a benefit.

Stella Vie is super light and has a gigantic solar panel. Therefore it can potentially run hundreds of miles a day on solar alone. If your car has 4 times the drag and a quarter of the area at half the PV efficiency, only about 10 added miles remain.

The better batteries get, the less reason to mount PV panels on cars.
