Or tell us that it takes 18-20 months of ownership of a Prius just to offset the pollution generated by the production of the car itself?
Somebody pointed out the obvious flaw with hybrids and electrics:
"What are they going to do with all those batteries?"
Before the most recent gas price situation and economic collapse, the big environmentalist cause was recycling cell phone batteries. Somebody figured out that no one kept a cell phone more than two years without buying a new model with more features, and that the land fills were filling up with toxic batteries.
Now they are using the same battery technology in cars. And they say that Nicad batteries are good for only 500 recharges (Rumorpedia: "Built in obsolescence; How camcorder manufacturers force you to buy a new camcorder by discontinuing the batteries).
A lead-acid battery just running the ignition and lights, lasts four or five years. A gel-cell doing the same lasts seven or eight years. Now, use the battery to run a high amp motor for moving the car itself. Toyota is supposedly eating the replacement costs for Prius batteries under warranty, for the purpose of maintaining it's position as the leader in the technology.
But where are all those dead batteries going? And why isn't anyone calculating the cost and damage to the environment into the benefit of the car?
The flaw I found was less dramatic, but just as serious. A starter motor in a gasoline powered car lasts eight or ten years. You get in, turn the key, drive, and don't shut the car off until you get where you are going. You don't have to restart the car unless you kill the engine on accident.
Hybrid cars stop the engine whenever you stop at a traffic light. And restart the engine when you pull away. Dozens or maybe hundreds of times per trip, depending on where you are driving. How much quicker are the starter motors in these Hybrids going to fail and need rebuilding?
And what about rebuilding the electric drive motors? How much more often will they need rebuilding compared to a four cylinder engine? And I don't recall any warning labels on engines saying that they were produced with hazardous chemicals, like those found on a new electric motor.
Future clunkers are being built and sold with no prayer of lasting out a ten year warranty, and they will need a new rebate program before the 2016 election to get all the dead electric and hybrid clunkers off the road.
