Today I read an article comparing Hydrogen powered cars to electric cars. According to the article, Hydrogen cars special fuel cells. These cells power the car and do not need to be recharged. Also, Hydrogen powered cars are emission free and, instead of spitting out harmful gases, they expel water. So why aren't Hydrogen cars being mass produced? They are expensive, costing hundreds of thousands of dollars per car. 

And then there are electric cars. Many see electric cars as slow, and uncool. However, in recent years, design and speed have become a lot better. Part of this is because battery technology has greatly improved. After charging an electric car for about 3.5 hours, it can be driven for about 225 miles. In addition, newer batteries will last longer and won't wear out as fast as they used to. So why aren't electric cars more popular? Well, not only can they be expensive, but the batteries that power them are very material-intensive. This means that the price of batteries has potential to fluctuate much like oil prices today. So if your battery craps out on you, it's possible you could be paying an arm and a leg for a new one.
