How do you get rid of milkspots?

Although on second thought... Maybe we're a bit too early. Maybe we shouldn't think about creating a new general yet when there isn't any demand for one. Maybe I'll bring it up again if the need arises.

>how much of that would you use driving for twenty or thirty minutes?
That's a bit of a difficult question to answer so let's look at easier data and see whether it would actually be a good, profitable addition to an EV.

So first off, let me correct myself: battery sizes range from 17.6kWh to 100kWh. With 17.6kWh you can drive for about 58 miles (93km) and with 100kWh you can drive over 300 miles (482km) before needing a recharge (source https://www.myev.com/research/ev-101/electric-vehicle-battery-basics).). Let's compare to a 100kWh battery since that's a nice round number. So if we take a U.S. average of sunny days in a year -- 205 days -- and assume that there is a good ten hours of continuous sunlight per sunny day, and we remember that with five hours of sunlight you can get 1.5kWh of power with a solar panel, we can calculate how much energy you'd get in a year and how many recharges that could constitute:

1.5kWh * 2 * 205 = 615kWh of power per annum. So with a single solar panel, you could fully charge a Tesla Model S with a 100kWh battery 6.15 times per year! Let's see how much that is in miles: 6.15 * 300 miles = 1,845 miles = 2,969km per year!

Now, let's see how much that would cost if you just plugged your car into a charger instead. The average price of electricity in the U.S. is 13.19c/kWh. For 615kWh, you'd therefore have to pay: 13.19c * 615 = 8,111.85c = ~$81.12. Let's multiply this by 25 (the lifespan of a solar panel): $81.12 * 25 = $2,028 electricity fees for charging an EV in the span of 25 years. Finally, let us see how much a solar panel costs. According to https://www.solarreviews.com/solar-panel-cost, the national U.S. average price is between $10,550 - $12,894 (tax incl.).

Unless I made wrong assumptions or didn't consider some details, powering an EV with solar power isn't economically feasible. Somebody please correct me if so
