I have a bit of mechanical knowledge. Electric cars will need a LOT less servicing. Electric motors are about 80% efficient.
Petrol/diesel are less than 30 % efficient.
inefficiencies are a LOT worse than they sound. a motor that is 100% efficient would be astoundingly reliable. Freakishly so.
Efficiency is not connected to reliability. (Except for in the case of improving efficiency where reliability can suffer. This is because any machine being pushed closer to its limit often comes at a cost of reliability. Car engines are intentionally turned to be less efficient for the purpose of increasing reliability)
A motor that is 100% efficient (despite breaking the laws of thermodynamics) would not be more reliable.
Quote:you are the idiot. You want to hold up progress because of something that has nothing to do with electric cars or any other electrical appliance. You conveniently ignore tail pipe emissions as though they don't exist. Electric cars do not pollute by themselves unlike fossil fool cars. Indirect emissions as a result of electric car usage improves as the grid is cleaned up. This does not happen with fossil fool cars !! There is no benefit in cleaning up the grid with fossil fool cars !!
Denying the consumer electric cars whilst allowing any other electrical appliance to use grid power is totally absurd and discriminatory !!
Get with the program moron !!
Do one is denying anyone the use of electric cars. It is the false advertising that they are better for the environment when at this point in time they are not. Likewise there is no better way to power a mobile phone then by electricity. Not so with cars.
Real environmentalist know that to make the world better we have to clean up the entire system. Fake "look how good I am" environmentalist jump on any idea if it shows an improvement in one area, even if it makes a bigger mess somewhere else.
Real Progress means moving in the right direction. Not moving an any direction just for the sake of it.
