your hands would probably still be warm, due to holding on to a hot beverage

thanks, much better!

"wherefore" means "why" not "where".
She wasn't asking him "where are you?" but rather "why did it have to be you?"

it already is.
you can make the engine more efficient, but at some point there is a minimum amount of energy needed to get the thing moving and they are already quite close to fully efficient. To reduce energy needed any further you can make the car lighter, but that obviously cannot be improved indefinitely.
assuming average conditions, somewhere on the order of 20 kw at cruising speed. More is needed to accelerate.
On the earth's surface, we get about 1kw per meter squared of energy from the sun. That's before factoring in inefficiencies in the panels, inefficiencies due to panels not oriented correctly, the battery charging system etc. Actual usable energy generated is significantly less than that.
So, with 100% efficient panels, you would still need, in theory, at minimum around 20 meters squared of perfectly efficient, perfectly oriented panels. Probably about 3 to 4 times more, in practice. There just is not enough surface area on a car.
nope. not "yet". just not physically possible. even with 100% efficient panels.
There just is not enough energy in the sunlight hitting the car. You would have to somehow make the sun shine brighter. Which is not really possible.
there doesn't need to be. It's not. plain and simple. There just isn't enough area on a car's body (remember, most of them won't even be oriented properly most of the time) for panels to generate enough power for self sufficiency. Even if the panels were 100% efficient. This will always be the case for any solar car.
why are you speaking in german?
