The Ultimate Commuter Vehicle Concept – electric regenerative renewable
In the recent automotive show in New York, visitors commented that “why only now are the big three motors of USA offering energy efficient compact vehicles after receiving massive government budget support?” Some commented that “have they not seen the writing on the wall several years back when the Japanese and other European car makers have started to include advanced technologies that provide greater fuel economy?” Finally some said “had the US car manufacturers and American consumers invested in fuel-efficient vehicles, the world oil price would have not soared to such $147 per barrel heights, the world would have avoided a global recession, and this global meltdown woud not have happened at all”
I guess these are all speculative, but it is never too late to do the right thing –> build fuel-efficient cars, save money on fuels, conserve oil so as not to drive its price upward, clean the environment and avoid global warming, and so on.
My concept of the ultimate vehicle consists of the following:
1) A small engine, perhaps of lawn-mower size, be it a spark-ignition, compression ignition or fuel cell, to drive an energy efficient electric generator (both prime mover engine and generator should be of best design and highest efficiency).
2) The electric generator charging an array of batteries of the best storage technology. The prime mover engine turns on only when the voltage of the battery pack goes lower than its set point.
3) The batteries drive the energy efficient electric motors or drive shafts on each wheel (either 2 wheel or 4 wheel drive).
4) The 4 wheels of the vehicle should be of such design that it has minimum rolling resistance, the vehicle itself is lightweight and made of composite materials that make it both strong but lightweight.
5) During day time, the batteries are primarily charged using solar PV cells, or in the absence of adequate sunlight and the voltage drops, the small engines cut in to drive the generator to charge the batteries.
6) When the vehicle is parked and there is no sunlight, it is charged using small wind vanes that could be deployed and retracked from the car’s ceiling.
