Diesels greener than battery cars, says Swiss gov report

Ivane, električni motori nisu problem. Ti motori imaju idealne karakteristike za primenu u vozilima. Na malim brojevima obrtaja imaju veliki obrtni moment i obratno. Nisu im potrebni prenosnici koji će peglati tu karakteristiku kao što je vozilima koja koriste SUS motore to neophodno da bi mogao da ih koristiš. To odmah znači i veći stepen iskorišćenja jer nemaš gubitke usled trenja u samom menjaču.

Problem je napajanje tj. baterije ili možda gorive ćelije tj. vodonik. Problem sa Lithium-ion baterijama je od skora na putu da se reši uz pomoć nanotehnologije. Pratim to već duže vreme i intenzivno se radi na tome. Te baterije će imati veći kapacitet a iste dimenzije. Ako budu imale primenu u nečemu što je više od laptopova više će se ulagati u njihov razvoj i pre će se doći do onoga što će biti zadovoljavajuće za sve.


Ne znam zbog čega stalno pominješ Prius. Prius je hibrid. Ovde govorimo o čisto električnim vozilima.

Advantages of electric vehicles

Mechanical

Electric motors are mechanically very simple.

Electric motors often achieve 90% energy conversion efficiency over the full range of speeds and power output and can be precisely controlled. They can also be combined with regenerative braking systems that have the ability to convert movement energy back into stored electricity. This can be used to reduce the wear on brake systems (and consequent brake pad dust) and reduce the total energy requirement of a trip. Regenerative braking is especially effective for start-and-stop city use.

They can be finely controlled and provide high torque from rest, unlike internal combustion engines, and do not need multiple gears to match power curves. This removes the need for gearboxes and torque converters.

Electric vehicles provide quiet and smooth operation and consequently have less noise and vibration than internal combustion engines. While this is a desirable attribute, it has also evoked concern that the absence of the usual sounds of an approaching vehicle poses a danger to blind, elderly and very young pedestrians. To mitigate this situation, automakers and individual companies are developing systems that produce warning sounds when electric vehicles are moving slowly, up to a speed when normal motion and rotation (road, suspension, electric motor, etc.) noises become audible

Diesel engines have energy efficiency of 45% and petrol engines of 30% plus gubici u menjaču.

Dobro de Ivane nećemo još da ti diramo Bembaru ))

_{ali radi se na tome}
