DESCRIPTION
Presentation about alternative fuels.
Citation preview
An electric car is a plug-in battery
powered car which is propelled by
electric motors.

Electric cars are generally more expensive than gasoline cars
Electric cars produce no pollution at the
tailpipe which will contribute to cleaner air in
cities
At low speeds, electric cars produced less roadway noise as compared to vehicles
propelled by an internal combustion engine
A hydrogen car is an alternative fuel vehicle that
uses hydrogen as its onboard fuel for motive
power.
There are two ways to get power using hydrogen:
Internal combustion engine (ICE)
Fuel cell
INTERNAL COMBUSTION ENGINE
(ICE)
Very similar to a normal petrol engine
It has two advantages from the fuel cell:
It is cheaper than the fuel cell.
It can be applied for solving those problems
where fuel cells are not a viable solution.
Mazda Rx-8
Wankel engine
They have a high production cost.
They can´t work with freezing temperatures.
They have a long lifetime.
Honda FCX Clarity
Ford Edge
It can be obtained through:
Thermochemical methods
Electrolysis
It doesn´t contribute to carbon dioxide
emission.
Fuel cell has a longer lifetime.
Hydrogen doesn´t occur naturally on the
Earth.
Hydrogen has low energy content per
volume unit.
It´s necesary build all the infraestructure
(refueling stations, pipeline transport…)

A water-fuelled car is an automobile that
works only with water(H2O).
Electrolysis process
split water into
hydrogen and oxygen.
Many water-fuelled cars obtain
hydrogen in a mixture of hydrogen and
oxygen called “oxyhydrogen” by the
electrolysis.
The hydrogen is burned,powering the car
and also providing the energy to
electrolyse more water.
1-The energy released in combustion is the same that the energy consumed in electrolysis,and there would be no energy to power the car,even assuming 100% efficiency.
2-Efficiency is like 20%.
In 2008 a Japanese company called
Genepax said that they had built a car
that worked only with water.
Solar cars:
-Is an electric vehicle powered by solar
electricity.
