The concept by which your car’s engine works has been around, at least as an idea, for over 800 years. The first concept of an internal combustion engine was done by a Mesopotamian named Al-Jazari in 1206. The Chinese, Mongols, and Arabs developed a working model in the 13th century. Da Vinci produced a design in 1509. In fact, there doesn’t seem to be a single inventor, but a long roster of contributing inventors and engineers. But even with all the improvements, it’s still the same basic principal.
But now, in the 21st century, the internal combustion engine is living on borrowed time. Gas and diesel fuel are proving too vulnerable to political and environmental pressures that make its supply and price unstable. There is also a question of how long the current reserves will last in the face of ever-rising demand. In response to these conditions, electric vehicles are attempting to move to the mainstream. But high cost, limited range and the fact that electricity still flows mostly from coal-fired power plants still, in the minds of most consumers, make them novelty items.
Hybrids have been a good compromise, combining the emission-less value of electric motors with the range of a traditional engine. This development is encouraging, although no one has yet given me a satisfactory answer to the question of what happens to the toxic battery packs after they wear out.
