IE, you drive up to a "gas station", you slide the battery pack out (or maybe it's in a tray or something), you pay the station for a new pack, put it in and you're off. The station keeps your depleted pack and recharges it.
Sort've like you can do now with propane. You take your empty tank there and grab a full one.
As far as electricity rates are going, I swear I pay less than 6 cents for a kWh. And that's not off peak or anything, just standard.
Make sure you add in the fuel surcharge, etc. |

Exactly what companies batteries will you be forcing everyone to use? Each manufacturer of a car will have their own battery packs.
Who disposes of these batteries?
Ever see a 2 kg laptop battery catch fire and explode? Now think of what would happen if that battery was 250 kg. The size needed to run a car for short distances.

Who advocated forcing anybody to use a particular company's batteries?
Who disposes of hybrid car batteries? |

I wouldn't force anything. Just let the market work its magic. There's a good reason why a lot of consumer electronics that use disposable batteries have standardized shapes and voltages (AA, AAA, C, etc.).

LI Poly batteries have a higher energy storage capacity per volume than normal Li Ion batteries and the battery is solid. It can't catch on fire (though it probably could get hot).
http://en.wikipedia.org/wiki/Lithium_ion_polymer_battery
Quote: here are many advantages of this design over the classic lithium ion design, including the fact that the solid polymer electrolyte is not flammable (unlike the organic solvent that the Li-Ion cell uses);
Quote: Who disposes of these batteries?
Again (though the wiki article doesn't really say), I would think that Li Poly batteries have an advantage here. Since the electrolyte is a solid, disposal shouldn't be a problem.
As far as who, that's a problem for the market, again.

This is a good article, but only relevent if we're talking about non Poly Li batteries. |

Batteries are coming into some great advances. Here's another one:

Quote: MUNICH (Reuters) - BMW will roll out the world's first hydrogen-burning car in serial production early next year, the German premium automaker said on Tuesday, eager to put its stamp on cars with green credentials.
ADVERTISEMENT
The specially equipped 7-Series executive cars emit only water vapor when running on hydrogen.
The car hits the market next April and will be shown at the Los Angeles car show in November, the company said. It had said in March the hydrogen cars would arrive within two years.
A spokesman said the car would be leased to selected customers rather than sold because of its high price. Leasing rates would be similar to those for a top-end BMW 760LI with a full-service package.
The BMW 7 Series Hydrogen 7 Saloon is powered by a 260 hp twelve-cylinder engine and accelerates from 0-100 km/h (62 mph) in 9.5 seconds. Top speed is limited electronically to 230 km/h.
BMW has said it intends to build a few hundred such cars at first. They will be able to switch between burning standard petrol and hydrogen so that drivers will not be left stranded while the infrastructure to deliver hydrogen is built up.
"The integration of hydrogen drive in an existing vehicle concept which has already proven its merits in the market paves the way for an alternative to conventional drive concepts fully accepted in the market and with all the assets the customer is looking for in practice," BMW said.
The space that two fuel tanks take up means only the 7-Series will offer the hydrogen package at first. BMW's long-term goal is to offer hydrogen motors in all its cars.
BMW unveiled the world's fastest hydrogen-powered car at the 2004 Paris auto show. Dubbed the H2R, it can exceed 300 kilometers (185 miles) per hour and reaches 100 km per hour from a standing start in around six seconds.
While BMW is developing fuel-cell driven cars as well, it says it is concentrating on the combustion engine because the sum total of its features and characteristics offers the largest number of advantages and benefits all in one.
This again proves that the free market is the best place for scientific advancement. Where there is a will, there is a way.
Anyway, is this cool or what?
:tu:
very very cool.I hope I can own a BMW :wink:
BTW,the more hydrogen-burning car is produced,the better the world will be.Get rid off the damn oil!!! |
