James Fallows and I share a hatred of the infernal machines:
Pound for pound, gallon for gallon, and hour-for-hour, the two-stroke gas powered engines in leaf blowers and similar equipment are vastly the dirtiest and most polluting kind of machinery still in legal use.
How can such little engines do so much damage? It’s all about technological progress, and the lack of it:
Over the past 50 years, gasoline engines for trucks and automobiles have become so much more efficient that they have reduced most of their damaging emissions-per-mile by at least 95 percent. This is not even to mention the rapid onset of electric-powered vehicles.
Two-stroke engines, by contrast, are based on long-obsolete technology that inefficiently burns a slosh of oil and gasoline, and pumps out much of the unburned fuel as toxic aerosols.
There is an obvious, rapidly improving alternative. That is battery-powered equipment (to say nothing of rakes).
I want them banned in Chicago. Let's start here.
