HUM 101 No Gas, No Problem Remember paying close to four dollars a gallon for gas? Well, if we were driving electric cars, we would be paying 1 cent per mile. Not to mention the benefit to the environment. The primary concerns regarding electric cars would be, where to charge, battery life, and the waste from batteries used in electric vehicles. On the other hand, there are many things being done to solve these problems. For example, a company called Tesla Motors has developed a car called the Tesla Roadster. It uses a lithium ion battery which can be recharged numerous times. According to the U.S. government, lithium ion batteries aren't an environmental hazard. "Lithium Ion batteries are classified by the federal government as non-hazardous waste and are safe for disposal in the normal municipal waste stream," says Kate Krebs of the National Recycling Coalition. (Panasonic) While other types of batteries include toxic metals such as cadmium, the metals in lithium ion batteries; cobalt, copper, nickel and iron, are considered safe for landfills or incinerators. Interestingly enough, lithium ion batteries contain an ionic form of lithium but no lithium metal. Before the use of lithium ion batteries, nickel cadmium was used in rechargeable batteries. The nickel cadmium battery is one of the more hazardous batteries in terms of disposal. If used in landfills, the cadmium will eventually dissolve itself and the toxic substance will seep into the water supply, causing serious health problems.
