This is just an interesting idea that requires a lot of assumption. But, that is the normal way of juggling with equations to see what would happen. More links at his home page: http://mypage.iu.edu/~nipoplaw/physics.html

If the assumptions are reasonable or more or less correct, or wrong, that is another story.
