| @brian Yes. One problem is the way electricity is generated. But the advantage of electricity is that is can be generated from different energy resources. China may rely now in coal, but in the future it may be otherwise. Coal fired plants can also be improved to reduce polutions. No rocket science technology is needed, and you have less points to control, there not so many coal plants as cars.. ;-) Besides. If you have the plug in+battery infrastructure in place now, half the work would already be done. When nuclear, hydroelectric or any other energy sources is installed the work will be done. There are two main goals: energy diversification and emission control About emission control with buses and trucks... Hybrid technology can also be applied to them, and as you indicate it may be more meaningful to do it with them. Applying hybrid technology to these means of transportation should not be more complicated than cars. By the way, there are already electric powered buses which uses batteries to bridge the gaps between the street hovering power cables they connect to to get power. Give them more flexibility. There is also an invention about a transport system, equivalent to capacity to a surface tram system, but thanks to robotics so flexible like bus. It is not tied to a rail network, can use normal roads. And propulsion can be gas+electric combination. But it is patent pending, can say nothing more about it ;-) |
