Unless you got a source for recycled grease that's not going to do the earth any favors. A biofuel crop is one species away from being as environmentally impoverished as a mall parking lot.

In the end, it all comes down to biodiversity. Poison Darts--Protecting the biodiversity of our world

I was watching Ingmar Bergman's Scenes From a Marriage (1973).

The thing is -- this is a film about middle class people going around having affairs in the city and countryside.   The thing is -- they used their cars a lot!   They were always driving to meet their newest lovers in a "flat" or in a country house.

I didn't see anyone get on a train at any time.  So, what's with this European train fixation?  If Swedes don't use the train, then who does??  

You are suffering from auto-erotic swedish troll syndrome.  Watch three "Seinfelds" and a Leave It To Beaver".  

Dream about Eddie Haskell's police career.  That should cure it.  If not, lather rinse and repeat.

Or just consult this oracle (gas leak).

No one steals cars, only trains.

Gristwits are always touting how "like in Europe they all use trains, mahnnn".   No so any more.

Europeans have seen the wisdom of abandoning smelly crowed flats and sprawling into the suburbs just like real Americans:

No trains run to the new suburbs where hundreds of thousands of Dubliners now live, and the few buses going there overflow with people. So nearly everyone drives -- to work, to shop, to take their children to school -- in what seems like a constant smoggy, traffic jam. Since 1990, emissions from transportation in Ireland have risen about 140 percent, the most in Europe. But Ireland is not alone.

Vehicular emissions are rising in nearly every European country, and across the globe. Because of increasing car and truck use, greenhouse-gas emissions are increasing even where pollution from industry is waning.

The 23 percent growth in vehicular emissions in Europe since 1990 has "offset" the effect of cleaner factories, according to a recent report by the European Environment Agency. The growth has occurred despite the invention of far more environmentally friendly fuels and cars.
