Dear Bob

Thanks for giving my calculations a realistic position and proportions in
relation to the rest of the water cycle. I am calmed down a little bit. But
my real concern is that we, - driving in our motorcars - faster and faster
are transforming the treasure box of the Earth - maybe supplied by the
comets too - into a water casket. The hydrocarbons are much too valuable
(could be used for other purposes), just to burn off along the roads. I have
these thoughts every time I am driving on the high way, looking at all the
other ignorants chasing each other. And that is happening all the time on
the roads all over the world.

I read somewhere, that US in the 1850ties, when the first oil was discovered
in Pennsylvania, had as much oil as Saudi Arabia. Where has that gone? And
what is happening right now? US imports barrels of oil from elsewhere.
Oilprices are increasing and all chinamen haven't got a car - yet.

Denmark has small suplies of oil in the North Sea (Norway got the brother
part). From about 2014 the oilproduction will decrease, and we have to lean
on our windmills alone. Windturbines and solarcells should be the answer to
the increasing lack of oil.
