1Igniting gasoline
In an experiment, researchers tried 2000 times to ignite gasoline with a lit cigarette, but failed 100% of the time. Liquid gas can't be ignited by a lit cigarette but the gas fumes from the pump can ignite from a cigarette, but only if that cigarette is burning at 450°C which they don't unless you puff on them. Unpuffed cigarette burns at 400°C, while puffed cigarette burns at 900°C.
2Asphalt pavement
As of 2009, over 3 million tons of asphalt pavements have been recycled and there is over a 99% recycling rate for asphalt.
3Soy biodiesel
If all the corn and soybean production in the U.S was diverted to corn ethanol and soy biodiesel, it would meet only 12% of gasoline demand and 6% of diesel demand.
