In this blog it talks about a new "green" vehicle, called the Air Car. This new car is powered by the expansion of compressed air, so there are zero emissions. It is a cheap alternative to gas powered cars. It can be as low as $7000 to purchase and it can go about 42 miles on only a dollar fill-up. There are some skeptics that are not sure how much impact the car could still have on the environment; considering the car does require some electricity and electricity does requires fossil fuels to be made. I think that this is an amazing development. I hope that the car's makers can work out any and all kinks so that it can start to be utilized as soon as possible. This article shows just how much more our World is becoming green and more respectful to the Earth.
