Hybrid Car Battery Pollution

Hybrid cars are a joke?
Consider the energy and pollution in the mining of nickel and making battery. Then, the energy required to transport the batteries to where the car is assembled. In addition to the energy required to charge the battery. Finally, think of the energy that the car used to carry not one but two engines. Is not it a joke?
Hybrids around management the best energy use by having a bidirectional storage device to cushion the energy produced by the internal combustion engine. Although the batteries are being used, are not only minimal, but not necessary, could easily be capacitors or flywheels, if you do not mind the loss of their energy while parked. They could even be compressed air. The disadvantage is the duplication of components, which both an electric drive and a combustion unit. However, as rising fuel prices, using the most efficient fuel now outweighs the weight penalty of hybrid vehicles. Just kidding, when fuel is cheap. With expensive fuel, the fuel is only prudent.
