Why NOT Electric Cars?

Electric cars are a great idea whose time hasn't come. Henry Ford wanted electric cars, but the problem then is the problem now. Why are electric cars so great? They can use electricity to power them, so they're renewable. So why aren't they the dominant transportation? Batteries.

• Lithium used in the Tesla comes from very few places, some of them hostile, and is only available in small quantities. It also gets damaged if its discharged halfway, losing 20% of its total capacity. This means a lithium battery is really about half what it says, until you use it hard, then its even less. Worse, until a year ago, the total available lithium on earth would have been enough for nearly 2 million Tesla electric cars. As there are 7 billion people this is a problem. Recently, more lithium was found in Wyoming so we might have enough for double that, which is still the same problem. If you don't have enough battery material for every single person, you have provided a motivation for crime and war. 
• Nickel Cadmium (Ni-Cad) get charge memory (chemical crystallization) and Nickel is nearly mined out. More will probably be found, but its just not good enough. 
• Nickel Iron can be charged more times than Ni-Cad but discharges slowly. These batteries end up in Golf Carts, which can do as much as 15-20 mph. 
• Lead Acid is very heavy and wrong for powering a car. We use them to start our cars and they weigh 20-30 lbs for one with little juice in it. 
• Aluminum Air fuel cells hold lots of power but can't be recharged so that won't work.  
• Hydrogen gas to run a fuel cell unfortunately leaks through solid metal like its barely there and is a fire and explosion hazard, as well as costing more power to make then is generated by turning it back into electricity. 

The solution eludes us. Until we can get a common material battery with ingredients available to absolutely everyone, electric cars are just a fantasy.
