They are already!
Unfortunately vehicles developed and powered by fuel cells are technologically problem prone, but some significant progress has been made already. Although cost prohibitive; eventually the consumers own demand coupled with the high cost of fossil fuels (and environmental problems concerned with hydrocarbons) will help to spur on fuel cell development futher.
The real question is; How soon will we see fuel cell powered cars mainstream?
The answer inevitably is when technological barriers are overcome to enable fuel cell developers to economically roll-out vehicles powered this way. In other words given time, expertise, and learning to understand and develop fuel cell technology properly (particularly economically derived hydrogen power) as well as consumer demand for cleaner alternatives to hydrocarbons will we ultimately see them at the forefront of our transportation system.
I think the DMFC (Direct Methanol Fuel Cell) will probably be the leading fuel cell technology that will prevail.
I attribute this to the fact that it is much easier and less energy intensive to extract the hydrogen from Methanol and convert it to electricity (or burn the hydrogen directly in a combustion engine) than it is for hydrogen derived from H2O. This is hydrogen on demand - as and when your engine needs it (produced at the source) rarther than carrying potentially dangerous cryogenic or pressurised hydrogen fuel tanks.
The downside to all this however is that Methanol is mostly produced using methane and other fossil hydrocarbons which sort of defeats the objective. As in the early days prior to the utilisation of crude oil; Methanol can be produced in other more environmentally friendly ways (for example by using biomass) but a major shift for change would be required as well as a rekindling of forgotten methanol production techniques.
Methanol Links are to the left
Because they are too expensive, big and heavy, the only way is to use them is in a pick-up truck, you place all the cells on the bed and even this way the range will be too short !, not more than 40 miles with one charge........
No, cells are the basic unit of life and cars are not living.
by being made smaller (smart cars), lighter, and using bio fuels. "Greener" is a big fraud especially when it comes to bio fuels, because a vehicle gets lower gas mileage using bio fuel, therefore using more fuel and pollutants.
There are already some fuel-cell cars out, they use a fuel cell. There have been prototypes of cars that run on water. Cars that run on hydrogen also. Electric cars definitely
The car battery normally is made up of six cells of 2volts each.
Cars made from aluminium use less fuel than cars made from steel because aluminium has a low density this makes the car to be lightweight. Whereas with steel, it has a high density so it makes the car to be very heavy. So if steel was used over the same journey more fuel would have to be used and therefore less fuel would be used if you used the metal aluminium.
now we have better fuel and can run some cars on electricity.
Nitrogen oxides are made by cars and lorries as they use fuel and the gas comes out.
Lighter weight, more aerodynamic, and more fuel efficient engines, transmissions, and tires.
Both are made of cells or cells with a nucleus
i dont know ask someone with cancer
Fuel injected. The last cars with carburetors that were sold on the US market were made in 1990.
In the USA, 1975.
Chevrolet made hybrid cars out of these models of their cars Malibu, Equinox Fuel Cell, Cruze Eco, Malibu Eco, Volt, Tahoe Hybrid, and the Silverado Hybrid. The only cars that don't run on gasoline at all are the Volt and the Equinox Fuel Cell.
The qualities of smart cars is that some are electric, but all are fuel efficient. Although they may be expensive on the purchase, they sure do pay off in the long run. More models are being made every year, improving from the model before.
Capillaries. But they do not exactly surround cells, being made of cells themselves.
Canadian and American made cars and trucks now put the fuel pump in the gas tank.
the first fuel car was first made in 1886 and it was called the Benz Patent Motorwagen.
The less weight, the better the fuel mileage.
Environmentally cars are specifically engineered to have superior mile per gallon, or MPG compared to normal cars. These comparisons can be made at KellyBlueBook website.
Ethanol is alcohol made from corn/sugar cane, etc. it is the same alcohol you drink. Cars that run on ethanol, have different fuel lines, injectors, ECU programming since ethanol runs at a different ai/fuel ratio than gasoline.
Newer cars are geared towards being more fuel efficient than older cars. Cars made in 2012, depending on engine size, will likely get much better gas mileage than your 1993 Buick. These older cars were geared more towards comfort and power and less towards improved gas mileage.
Trucks are larger heavy, and more powerful. They take more fuel.Using the formula Force = Mass x Acceleration, You know that with more to get the same Acceleration (speed) with more Mass, you need way more Force (which is made by fuel being burnt.)
