The cityZenn – Dream Electric Car
Till now we have battery operated cars or hybrid cars. Hybrid cars reduce your gas consumption and air pollution. If you are using battery operated cars, you can’t drive on the spur of a moment. You have to PLAN and recharge the batteries. Otherwise your vehicle will carry you for a few miles and then it will stop and you will be stuck somewhere you don’t want to. You also have to compromise on the size, space and speed of the car. And since you are using a storage device in the car, you have to fear and respect that too.
Can’t we have a car that goes 250 miles on a single charge? Can’t we recharge it in five minutes? And drive it at 80 M.P.H.? Don’t dismiss it as wishful thinking! A Toronto-based firm ZENN Motors promises such a highway capable model in near future with no gasoline engine, no batteries, and no emissions!
“cityZENN” model will use “Electrical Energy Storage Units” (EESUs), containing ultracapacitors, also known as supercapacitors. These capacitors use barium tinanate coated with aluminum oxide and glass which will help in conquering the disadvantages of chemical batteries. They are more powerful than basic capacitors. Ultracapacitors can absorb power or send a charge faster than chemical batteries because of activated carbon at their cores. They also score over durability and have better tolerance for extreme temperatures.
Safety is a serious concern for vehicles whether powered by petrol, diesel, batteries or ultracapacitors. The storage devices shouldn’t burst into flames under extreme conditions. The new ultracapacitors are supposed to instantly discharge to the ground in case of a crash.
Many have cast doubts over “cityZENN” claims and apprehensive about its deliverables but the analysts and researchers are hesitant to dismiss the possibility of “cityZENN” entirely. Joel Schindall, a Massachusetts Institute of Technology professor who is using nanotechnology to improve ultracapacitors, says “I don’t doubt that they have built a device on a small scale that does store the amounts of energy they are talking about. I just don’t know if they can manage the process of scaling it up … for commercial applications.”
