Electric car will not work at this time and not in near future as well. There is simply not enough energy density in today’s batteries. Only electric car that are feasible are golf cart type that can be used for short commute around the town and need to be recharged any time you park somewhere and can be rented anywhere using credit card.
Future of mass transportation is high speed trains, not gasoline or Diesel cars, and small electric cars around the town. Just copy France and Germany. Electric cars are simply not ready yet probably will never be.
Hybrid and electric cars are expensive nonsense; better mileage is being achieved by small simpler cheaper Diesel cars, just check Volkswagen Diesels.
All this electric and hybrid car noise is made by greedy corporations that do not want to sell small diesel cars but make more money selling extremely expensive electric and hybrid cars. Electric cars are slower by every mile they make, at the end of battery charge these cars just crawl. Unfortunately, media is simply brainwashing the consumers.
Recently group of English magazine “Car” journalist traveled on I-10 from Jacksonville FL to Los Angeles including city driving along the route using European 101 HP Golf Diesel. Not available in the USA. They averaged 71 MPG which is not possible with any of these nonsense hybrid cars.
Until some other type of fuel becomes widely available (nothing is in sight and probably won’t be for decades and oil is running out) car manufacturing should go Diesel and reduce power to 30-70 HP which would be sufficient for 70 MPH on highways and with fuel economy better than any current hybrid. Yes, car would be sluggish so what: hybrids are slow as well and there are speed limits everywhere except on some German highways.
Oil should be saved by eliminating heavy trucks from roads and using trains and ships as much as possible. Transatlantic travel should go atomic: Large atomic powered ships should be built with capacity of 20-30 thousand passengers. Today, fast ship powered by atomic reactor can make trip from New York to London or France in 60 hours. In addition, it will be way cheaper and more comfortable than any airplane. One can walk and work using computers, there will be no jet lag.
But then comes trucking lobbyist, airplane industry lobbyist and who knows how many other lobbyists and contribute to senators re-election and this is the end of story regarding smart energy policy and many other policies benefiting society, not corporations. This is happening in so called free market economy: This is the same economy that does not allow prescription drugs import. It is called monopoly.
At this time oil is not replaceable by anything, simply no other mobile energy source has enough energy density. Small Diesel powered cars are good temporary solution until much better batteries are developed (if ever developed) or Hydrogen manufacturing process is made much much cheaper.
Wind and solar energy is stationary energy and cannot be used for transportation purposes other than trains using electrical energy. Someone should tell this fact to “green” guys.
All these electric cars will fail: Chevrolet Volt, Nisan Leaf, Fisker, Tesla, they will never make profit.
