What Is an Objectã¢â‚¬â„¢s Acceleration if It Is Moving at 30 M/s and Comes to a Stop in 5 S?
Wow! Thank you to Debbie for passing this trivial gem along. I'm simply speechless. And to think we nearly bought a Prius to exist "green friendly".
At present I'm glad nosotros opted for a totally pimped out 06′ Honda Civic. That manner we actually exercise have one of the most "green friendly" vehicles to kickoff my arguably-worse-than-a-Hummer 05′ Nissan Titan!
Prius Outdoes Hummer in Environmental Harm – Past Chris Demorro
The Toyota Prius has become the flagship car for those in our society so environmentally conscious that they are willing to spend a premium to prove the world how much they care. Unfortunately for them, their ultimate ‘green car’ is the source of some of the worst pollution in Northward America; it takes more combined energy per Prius to produce than a Hummer.
Earlier we delve into the seedy underworld of hybrids, yous must first sympathize how a hybrid works. For this, nosotros will use the most popular hybrid on the market, the Toyota Prius.
The Prius is powered by not i, merely two engines: a standard 76 horsepower, 1.five-liter gas engine found in most cars today and a battery- powered engine that deals out 67 horsepower and a whooping 295ft/lbs of torque, beneath 2000 revolutions per infinitesimal. Essentially, the Toyota Synergy Bulldoze system, equally it is and so chosen, propels the car from a dead stop to upwardly to 30mph. This is where the largest percent of gas is consumed. As any physics major can tell y'all, it takes more energy to get an object moving than to go along it moving. The battery is recharged through the braking arrangement, as well as when the gasoline engine takes over anywhere due north of 30mph. It seems like a great energy efficient and environmentally sound car, right?You lot would be correct if you went by the old regime EPA estimates, which netted the Prius an incredible 60 miles per gallon in the city and 51 miles per gallon on the highway. Unfortunately for Toyota, the government realized how unrealistic their EPA tests were, which consisted of highway speeds express to 55mph and acceleration of only 3.3 mph per second. The new tests which touch on all 2008 models give a much more realistic rating with highway speeds of 80mph and dispatch of 8mph per 2d. This has dropped the Prius’s EPA down past 25 percent to an boilerplate of 45mpg. This now puts the Toyota within spitting distance of cars like the Chevy Aveo, which costs less then half what the Prius costs.
Notwithstanding, if that was the merely outcome with the Prius, I wouldn’t be writing this article. It gets much worse.
Building a Toyota Prius causes more than environmental damage than a Hummer that is on the road for three times longer than a Prius. As already noted, the Prius is partly driven by a battery which contains nickel. The nickel is mined and smelted at a plant in Sudbury, Ontario. This plant has acquired so much environmental damage to the surrounding environment that NASA has used the ‘dead zone’ around the plant to examination moon rovers. The area effectually the plant is devoid of any life for miles.
The constitute is the source of all the nickel found in a Prius’ battery and Toyota purchases i,000 tons annually. Dubbed the Superstack, the plague-manufacturing plant has spread sulfur dioxide across northern Ontario, becoming every environmentalist’southward nightmare.
â€Å"The acid pelting effectually Sudbury was and then bad it destroyed all the plants and the soil slid down off the hillside,†said Canadian Greenpeace energy-coordinator David Martin during an interview with Mail, a British-based newspaper.
All of this would be bad enough in and of itself; however, the journey to make a hybrid doesn’t end there. The nickel produced by this disastrous establish is shipped via massive container ship to the largest nickel refinery in Europe. From in that location, the nickel hops over to China to produce ‘nickel foam.’ From in that location, information technology goes to Japan. Finally, the completed batteries are shipped to the United States, finalizing the around-the-world trip required to produce a single Prius bombardment. Are these not sounding less and less like environmentally sound cars and more like a farce?
Expect, I haven’t even got to the best part however.
When you pool together all the combined free energy it takes to bulldoze and build a Toyota Prius, the flagship car of energy fanatics, information technology takes well-nigh 50 percentage more energy than a Hummer – the Prius’s arch nemesis.
Through a report past CNW Marketing chosen â€Å"Dust to Dust,†the total combined energy is taken from all the electrical, fuel, transportation, materials (metallic, plastic, etc) and hundreds of other factors over the expected lifetime of a vehicle. The Prius costs an average of $3.25 per mile driven over a lifetime of 100,000 miles – the expected lifespan of the Hybrid.
The Hummer, on the other manus, costs a more fiscal $1.95 per mile to put on the road over an expected lifetime of 300,000 miles. That ways the Hummer will terminal 3 times longer than a Prius and use less combined energy doing it.
So, if you are actually an environmentalist – ditch the Prius. Instead, buy one of the most economic cars available – a Toyota Scion xB. The Scion only costs a paltry $0.48 per mile to put on the road. If y'all are all the same obsessed over gas mileage – purchase a Chevy Aveo and ready that pb foot.
One terminal fun fact for you lot: it takes five years to offset the premium cost of a Prius. Meaning, you have to wait 60 months to save any coin over a non-hybrid car considering of lower gas expenses.
