they burn gas for that 30 seconds to 4 minutes don't they?
Yes, in lieu of burning it for 20 to 40 years.
If its to save the planet why don't they seize the engine without running it at high RPM till it dies? Why not hydro-lock it? Or pour sand and water down the intake manifold? There are more Eco friendly ways to kill an engine.
I'd be willing to bet that the seizing method was created by people smarter than you and I, taking not only environmental concerns into consideration, but also time efficiency, cost efficiency, etc.
I'm sure filling a crankcase with chlorine then burning it is a fantastically eco-friendly option.
For #1 see below
Just how is sand and water creative? The seizing method is a crude hillbilly method. Drain oil, fill with sand and water, start engine foot to floor.
I said fill with bleach and run for 10 seconds it would distribute the bleach not heat it up and burn. Any gasses created would not be as much as running it for several minutes. I'm not saying that's the best just that there are alternatives.
for 1 thing the car traded in would be unlikely to last 20-40 years
Based on what data?
but even if it did you still have to take into account the car they buy. Even new cars pollute.
You make it sound as if they get rid of the car and get a zero emission type vehicle.
Nope. But since you seem so sure that this program has a negative environment impact, please share with us the data you used to come to that conclusion. You did base that conclusion on actual numerical data, right? You're not just saying what you THINK is true, are you?
Lets see average mileage for Americans is what 10-12k miles in a year? In 20 years the miles would be 200-240k miles on a car. Some cars will last that long many will not. But you said they last 20-40 MORE so add the mileage of the car already. Of course double the figures for the 40 years.
I never said that it has a negative impact did I? All I said is that there are alternative ways to seizing an engine without running it at high RPMs till it dies.
Don't get me wrong I am NOT an environmentalist. I take care of my land and do plant trees, grass, etc. I recycle metals and take used oil to be recycled. I have done those things before it became popular with being "green". I own a Jeep and a V8 camaro. I drag race the camaro and off road with the jeep. I'm more worried about MPG then emissions. Some things can be taken too far.
If we HAVE kill the cars lets do it in a humane fashion... Quick and efficient, not go till she blows.
