Overview:
Electric Vehicles are a key part of our tomorrow and how we get there. If we can get all the fossil fuel vehicles off our roads, out of our seas and out of our skies, we'll have a much better environment. This community is where we discuss the various different vehicles and news stories regarding electric transportation.

This seems like a fragile gimmick. You might get $0.10 of power generation or five miles after parking in the sun all day?
500W will give you 1-2 miles of range per hour on a sunny day. If your commute is 5 miles in a sunny area, you won't need gas.
You'd probably do better with a bicycle though.
How much power does the A/C use in a car like that? You could probably run the A/C for free when it's sunny.
When I had a rental Bolt EUV, perhaps a bit larger than this, air conditioning seemed to use about half a kW while sitting at the stop lights, so maybe 500 Wh? So your guess might track, actually.
Probably more than 500W considering you're literally sitting in a greenhouse.
Maybe if you blocked off most of the windoes on the sunny side with reflectors.
Or just walk.
If you park outside and don’t drive every day it sort of makes sense.
And if you partk at work, it's a potential 8 ours if charging.
12 miles, right on the mark for 80% of US commutes.
But if I don't buy a 7000lb battery pack I'll have to take drugs for my range anxiety, which is in the next DVM, or, do simple math in my head.
Only in a communist state, comrade.
Aptera has been promising this since 2009 and people still invest. And that $0.10 is in July near the equator on a street with no trees.
