I like the fact that this little spot encourages cycling for transportation. The more people ride bicycles, the more they will find out how useful they are. 2 miles is a very small distance for cycling. About 10 minutes and your there.

inKrakow:

Gasoline is about 85% carbon and 15% hydrogen by weight. When burned it combines with oxygen to form CO2 and water. So if you start with 7 lbs. of gasoline you have about 6 lbs. of carbon. Each carbon atom (atomic wt. 12) combines with two oxygen atoms (atomic wt. 2 x 16) to give you a total of about 22 lbs. of CO2.

A gallon of gas is a little less than 7 lbs. so the 20 lb. figure for CO2 looks about right.

Actually, it very well could be true. 1 lb of gas may weigh less than half of 20 lbs, but, it ain't the only thing burning. Lots of oxygen is involved and the amount needed to burn a gallon of gas is considerable.

Wow! 20lbs of CO2 from one gallon of gas! Amazing! Is this the conversion of energy to matter? or something else?

Or are we just taking somebody's word for it, and parroting it uncritically? I love cycling as much as anybody else, but let's not resort to hyperbole (lies) to get your point across...
