Because first if all you would need thin-film solar panels over standard crystalline silicon based ones (to minimize the weight) which are less efficient. You also have less surface area on a car. (solar panels would work great on a trailer, car not so much as you won't generate much).
You will have to wait for solar paint to become commercialized and more efficient to make it work realistically.
“I don’t know why they don’t build solar panels into the upper surfaces…”
It would be a waste because the solar panels would only put out enough power to barely charge the battery – even after an entire day and they are a bit fragile.
The battery in the car is probably capable of storing 20 to 30+ KW (kilowatts) of power (I didn’t look it up). To recharge a 30KW battery pack requires quite a lot of power (well…close to 30KW if the battery is nearly dead).

That’s kind of a stupid comment, SSC. Worthy of a libturd. Please provide a link that shows Norris saying that about Glenn or STFU.

Interesting photo choice by the Blaze. Obama shaking hands with Bibi, but in the background, “the fire has gone out between Obama and Bibi.

Wonder if his BOLD, CONSERVATIVE agenda includes his massive amnesty plans?

Have you also noticed that these first primaries were open primaries where anyone could come in and vote in either party. Trump has won those. The states with the closed primaries go for Cruz. Most of the remaining primaries are closed primaries.
Trumpbots shouldn’t get too excited.

Are you kidding? After all the crap Kerry has done as Sec of State? I cant fathom what this country would be like if Kerry or Algore got in.
W was, and still is, better than Kerry ever would have been.

What’s up with that neck, too?

I doubt it will happen. Cruz will pick a semi-establishment guy for his VP to balance out hos ticket just as Reagan picked GHWB.

It’s called compromising or values or in establishment Republican speak, just compromise, go along to get along.
and, their progressive republican followers
