Electric Cars
Next time someone complains about how GM, Ford, and Chrysler (or even Honda and Toyota!) are not working on a Pure Electric Vehicle (a la Tesla), I’m just going to point them at this editorial. The problem here is that people are looking at the rate at which the consumer electronics industry is moving and telling the automobile industry to keep up. “Look at my iPod!”, people say. “I get twice the storage in half the price and the thing’s 1/10th the size of the original iPod!”. Well, maybe they’re just not realizing that you have to replace your iPod every 2 years because the battery is not replaceable and the damned thing just breaks down after a while. Just imagine what would happen if the same thing happened to the cars and trucks that we drive.
On top of the safety thing (and this is a big thing - I’ve witnessed aftermaths of battery fires and it ain’t pretty), there are two other issues that the writer only makes oblique references to - the cost and the lifespan. Lithium Ion batteries are expensive. For the solar car, the budget set aside for it alone would’ve been good enough for a nice car (new or used, depending on the solar car
). Prices have been going down due to the proliferation of consumer electronics but for a full size car, you’re going to need a lot of those 18650’s. Factor in the 300 or so (might be higher now) charge cycles and the natural degradation that happens, we’re going to end up with something that will require an expensive battery replacement every 2~3 years or so. People are gushing about the plug-in hybrids but since their battery reserve is far smaller than that of a full electric vehicles, it just means that the plug-in’s are going to hit the battery wall that much sooner.
At the end, as long as we’re talking about chemical reactions, it comes down to this simple equation:
More Energy In Smaller Volume = Bigger Explosion!
I realize that I’m basically mouthing things off without providing any real alternatives… but maybe I just believe that informed skepticism is better than uninformed exuberance.
