Actually, there's a law about this. Called the "Law of unintended consequences", and you listed a lot of them:
- Additional pollution (extra smoke as you reported)
- Adjustments and maintenance on heating systems not designed for biofuel
- Additional energy expenditures to keep said fuel from congealing on trucks
- Banning of all existing outdoors fuel storage containers
- Additional gas used to haul loaded fuel truck to secondary biofuel loading docks
Now -- just wait till "Cap and Tax" is upon us. The unintended consequences will be huge. Just like the health care bill. And lots of other idealistic, unpractical things rammed down our throats by liberal "do it my way" critters.
