New York Cabs Going Green

"NEW YORK (Reuters) - New York City's yellow taxi fleet now will go green at the rate of 300 new hybrid cars a month, Mayor Michael Bloomberg said on Wednesday, citing an agreement with car-makers to supply the fuel-light cabs.

There are already more than 1,300 hybrid taxis in the city, and each one saves its drivers about $6,500 a year, Taxi and Limousine Commission Chairman Matthew Daus said in a joint statement with the mayor."

Yes, Hybrids cars are better than any other cars. Electric cars kept pollution free environment according to other cars.
This is the good decision had been taken by NY mayor.

Cool! Now we just need to get the rest of the country on track!

Or...

We accept the answer may not be hybrids with expensive battery packs, high energy-to-produce costs, theoretical mileage that isn't happening in the real world for which the word is spreading, and higher end-of-use disposal costs (if not classified as hazardous waste due to the batteries). If you're making regular 50 mile one-way commutes on interstate highways, do you think you're going to see any mileage savings over a regular vehicle when both are burning gas yet the one also is hauling a battery pack?

For getting yourself around day-to-day buy a gas-thrifty cheap-to-produce cheap-to-buy small car, like a Kia or a Chevy Aveo, that some day can go straight to the crusher and straight to recycling. I recommend manual transmission if available, and no unnecessary options that consume power. Does anyone really need seat warmers?

Hybrids may be the hot new technology that all the "green" cool people are driving, but the facts are the technology still isn't quite there yet. Buying smart and small traditional vehicles is still better for the environment and your wallet.

Except that hybrid cars do use less gas. And when a car drives as much as a taxi, the environmental benefits probably do outweigh the batteries.
Like Goodhart says. For people away from congested urban areas, which is still most of the country, the higher cost of buying plus increased insurance costs (comprehensive w/ higher-priced car) isn't significantly offset by the fuel savings. Then comes the point where they'll be off warranty, maintenance costs look higher. People needing cheap transportation, that's hopefully reliable, won't want a used hybrid if that means getting hit with a huge battery replacement bill. Read about the real world mileage for a Prius, compare to non-hybrids. Also note the battery usage design, to get between 7 to 10 years from the pack they use it at only about 50% of charge. So you're paying double what a good battery design would cost, and I find that figuring only 7-10 years as the life of a vehicle is somewhat offensive. I drive ones over 20 years old rather cheaply, vehicles that last longer yield lower energy use for manufacture per driver and are more economical to own, though it does mean fewer new sales. Boo-hoo. Buying new and driving until the wheels fall off, you could do better with a thrifty gsasoline car, even more with a diesel.

Plus, they're designing hybrids wrong.

Refer to the Wikipedia hybrid vehicle drivetrain article. Oh, and notice how many things are being called hybrids, it's a better marketing term than natural. (I ate some chips before cooked in all-natural oil. Crude oil is made from long-dead organic life, what's more natural than organic?)

Hybrids are being designed with parallel drivetrains, tossing in an electric motor + battery pack and controls + unneeded complexity. Hybrids like the Prius use a combination drivetrain, a combining of compromises. (Also note how the much-marketed Toyota Synergy Drive is really a cheap low-end implementation.)

I have long believed the best implementation is the series drivetrain. Why? Because that's how electrics should look. Hybrids are the transition vehicle until all-electric can be universal and cheaply implemented. The series design is an electric with on-board generation. It's very flexible, you can use practically any fuel or engine design, even Stirling, run as efficient and low-emission as possible. Batteries can be proven less-expensive lead-acid types, which recycle well. They can be relatively easily retrofitted to all-electric, ditch the engine/generator and fuel tank, add more batteries.

Plus only with series can you use motors at the wheels. Many things simplify then, and the technology for driving motors with high torque at low-to-high speeds has long been available in industry. Use a motor at each wheel, and complete traction control, all-wheel ABS, even steering assisted by varying wheel speed thus no need for hydraulics, becomes a software issue, easily addressed. "Drivetrain" becomes an archaic term.

Read this article that Wikipedia links to, especially these comments. Very informative.

You want to talk about a really efficient parallel or combo hybrid design? The Prius is not it. Hydraulic hybrids are doing better than battery-charging hybrids. Hydraulics. Now that's saying a lot.

Everything you typed up above is just wasted fodder, because it all boils down to one simple fact:

This thread is not a thread about hybrids. This is a thread about the New York taxi cabs that are going to be hybrids. New York taxis are not in isolated country areas, they are in the congested urban areas, and are almost constantly driving. The amount of gas you would save if you were constantly driving in a hybrid vs. a normal car will overall save a substantial amount of gas and money.

But we got here from:
Cool! Now we just need to get the rest of the country on track!
The "rest of the country" is not New York City.

Question: The cabs have their own garages. Why didn't they just go all-electric with recharging stations at the garages? I thought congested urban areas were the ideal places for zero-emission electrics.
The big problem comes when you compare the average 25,000 dollar to the 95,000 dollar electric car.

I didn't realize it was such a price difference. I guess that would be why, then. Plus, electric cars may not last all day like they need them to. Gas stations are quicker and everywhere. Charging stations are slow and only at their garage.
In fact most electric cars will last around 600 miles before dieing and a lot of gas stations have charging stations.
