Scientists develop mega-thin solar cells that could be shockingly easy to produce: ‘As rapid as printing a newspaper’::These cells could be laminated onto various kinds of surfaces, such as the sails of a boat to provide power while at sea.

More like, it would take 8 days of constant sun to have an hour of driving.

Currently. Technology gets better

No, there is literally only so much energy radiated by the sun in a certain area. The number of square feet of roof on a car is just too small to propel it, even with magic theoretical 100% efficient panels.

You do know cars don't have to move all the time right? If I was on a road trip and got stuck because of no juice for whatever reason, I would be able to camp wherever I am for a couple days and then have enough to move.

Your thinking is pretty small minded

This isn’t some theoretical thing I’m making up. It’s really basic math and physics you should have learned in high school. To do a trip of a few miles you would have to charge for a week. Here is a good explainer with demonstration cars that have been physically built, maybe that will help drive the point home.

As outlined elsewhere in this thread, you'd have to move the Earth closer to the sun for this to be feasible. You can only get so much solar power as it stands, and even 100% efficient panels would only go so far.

Nah. Even 1% power is better than 0% power

Not when it costs any amount of money to do so.
