When the huricane hits and there is no safe public water, how about putting some bottles of water in a car with the windows rolled up to pasturize it?

Please critically evaluate this idea. State reasoning clearly.

Here is a link on pasturizing water:

And here is a link on how hot it can get in a car:

What factors would maximize the temperature. Which angle relative to the sun? Shades on the north side?

What size an object in space would have to be in order to have just enough gravity to hold a 200lb person to it's surface, yet so little gravity that one could jump clean off of it?
Is there a equation one could use to figure this out and what would this phenomenon be called?
