No matter how much the ISIS terrorizes innocents, no matter how much Kim Jong-Un threatens to nuke USA over and over again, no matter how much Russia tries to annex lost territories, the ultimate war is with global warming. It’s a silent assassin, dawdling in the shadows, killing us softly day by day. Almost every sector of our industrial operations contributes a bit to it and in the long run that can cost us our lives. While initiatives like the Kyoto Protocol, spread awareness and help reduce the 21% of greenhouse gases’ emissions as a result of the public’s actions, there is still the necessity to finish the 56% of the emissions produced by transport and electricity production.
Many vehicle companies have realized this and designed green electric cars, like the Tesla Model S. The car uses an induction motor instead of an engine making it less noisy and electricity as fuel. The electricity comes from a battery pack placed in the car which can be recharged by connecting it to charge stations or even wireless-ly through electromagnetic induction. What’s better is that the car has zero emissions; it does not even have an exhaust pipe! If the electricity supplied to the car was produced by non-fossil fuel sources, which is easily possible through nuclear and other renewable sources, then the car can truly be dubbed environment-friendly. And where oil is imported for transportation fuel, electric cars can save great economic costs allowing investment elsewhere.
The model is slowly being adapted in all transportation standards like trucks saving drivers roughly $1000 annually for gasoline money and for airplanes, well there’s something called algal fuel, that can make the airplane another environment-friendly vehicle. Norway has switched more than half of its cars to hybrid or electric standards! While this can surely motivate other countries to follow in their deed there are so many other ideas that can transform that 56% to an almost 0% for example turbines and generators could be attached to all the wheels of an electric vehicle and produce electricity from the kinetic movement of the wheels. This is not a perpetual motion concept because the electricity produced by the turbine will always be lesser than the electricity used to power the wheel, as stated by the laws of thermodynamics. Some energy will always be lost as heat energy while overcoming the forces of drag during acceleration; but as more than one-third of the fuel is consumed in doing this all that energy can be converted back to electrical energy and charge the battery pack in the car, eventually reducing the amount of electricity and time needed to charge the vehicle at stations. This can greatly improve the overall efficiency of the vehicle and although questions of the increased mass of the vehicle due to this set-up remain, that can easily be tackled with the growing innovation in today’s world.
