Energy conservation: Up to 88% of a vehicle’s gasoline is spent on “various thermal, frictional, and standby losses in the engine and exhaust system,” (reference) but our system would instead harness this wasted energy to power the car. At a time when petroleum, a finite resource, is becoming more and more inaccessible, our invention would provide an energy-efficient alternative to both the gasoline-powered car and the hybrid.

 
Environment: The lessening of gas usage would result in a decrease in greenhouse emissions of carbon dioxide.  One of the major problems in our world today is global warming, and it is caused primarily by car exhaust. 

Economy: The consumer would gradually save money though the efficiency of our system, and there would be less worry about fluctuating gas prices. Eventually, there would be less need for gasoline and in the process, less dependency on foreign oil.
