Stockolm's buses run on booze

In Stockolm, they confiscate smugged booze at the Sweden border, and now it is used to power the buses, trucks and trains. Almost all of the 700,000 litres of seized booze each year, goes to a processing plant for conversion into biogas.

Smuggled beer, wine and liquor is taken to a plant in Linkoping, 125 miles southwest of Stockholm, where it is heated and converted into biogas. One quart of pure alcohol is enough to make about a tenth of a gallon of biogas. And it is good business, because the booze to make it is free. It is all pumped into a big tank, which is jokingly called "the giant cocktail".

This project also helps the country's efforts to reduce its dependency on fossil fuels blamed for global warming.
