Apparently, it's happening now. This wont please Hillcountryfun | Forums | Tesla Motors

I like this idea. Also, energy divided by distance is force. So, instead of measuring "gas mileage" in Wh/mile (or kJ/mile), you could measure it in pounds or newtons. The interpretation is that it's the force with which the wheels drive the car forward against air resistance, rolling...

It probably is linear. It can't be logarithmic all the way to zero. Zero is infinitely far down on a logarithmic scale.

Perhaps that roof converts some of the incident sunlight to electricity and lets the rest through. In that case, it would look as if it had a more or less dark tint, and it wouldn't generate as much electricity as a solar panel that absorbed all of the light that fell on it.

I don't see how a solar panel could possibly be transparent. It has to absorb the sunlight in order to convert it to electricity.

What does it mean when it says that they don't cover "any loss which would not have occurred in the absence of one or more of the following excluded events"? It sounds like they d​o cover losses that would have occurred anyway. I guess it depends on exactly what the excluded events are, which...

It probably doesn't matter much, since the two numbers are so close, but page 19 of the Model S Safety Information booklet, available at https://www.teslamotors.com/mytesla/manuals/, says 175 Nm. - - - Updated - - - I don't understand the joke about hydrogen embrittlement.

I agree, for all practical purposes. Basically, modelling it that way does pretend that there's no friction with the road during the actual collision, but this is ok because such friction is so much weaker than the other forces involved. - - - Updated - - - I can't figure out what your...

You're just computing the total kinetic energy of the two cars before the collision. I don't see the relevance of that number to the severity of the collision. Consider two different collisions. Both involve two 1-ton cars. In one, a 51-mph car collides head-on with a 50-mph car going in the...
