The technology already largely exists, it just seems that government (at least here in North America) largely ignores it. India has recently developed a car that can run entirely on compressed air; able to go 160 miles (about that) on a single tank, up to 65 Mph. Japan has made an all-electric car running off the latest advancements in lithium-ion battery technology, with the ability to drive up to 300Kph and go several hours on a single charge. Another company, I wish I could remember which one, has recently made their first fully-functional and phenominally-effective hydrogen-powered car.

As is, there have been many, many electric cars that can match and surpass their gasoline-powered counterparts. Yet so governments and businesses continue to perpetuate the myth that an electric car can only exist as a weak and inneficient go-kart. One thing I'm sure of; bio-diesal is not the solution! Mexicans are already finding it exceedingly difficult buy corn tortilla's because of the corn shortage being put into fuel. One estimate I heard from a scientist on CNN purported that if we used all the corn in America to fuel our cars, it would cover 2% of our fuel needs.

Sugar-cane is far more effective anyway, with 3x the energy-output of corn, but unfortunately doesn't grow very well in most North American climates. Brazil has seemed to have done a fine job utilizing it to cover 85% of their car-fuel consumption, but I still don't like it because it depletes soil nutrients that should not be wasted. What we need is a fuel source that won't deplete another essential resource like food.
