Think Green. Second hand car parts will save you money, but they will save the environment as well. Producing and shipping new parts takes a lot of energy and pollution, so try to find a used car part if you can! http://bartebben.com/virtual-tour-bart-ebben-bv.html
The Tata AirPod is a city car running on compressed air (as well as a battery-powered electric motor). The ease of converting air into an energy source using simple compressors means charging stations can be placed anywhere, and they require no provisioning — no trucks delivering gas, ethanol, or hydrogen — and they produce no emissions, just discharge of the air. The AirPod can run 125mi (200k) at a top speed between 28 to 43mph (45 to 70kph).
