this slide shows what will be the future of our car which have zero emmiion and based on alternative source of fuel.

1. A PRESENTATION
ON
“FUTURE OF CARS”
AND
“ITS FUEL”

2. • Petroleum Displacement
• Depleting Non renewable Energy
• Air Quality Improvement
• Greenhouse Gas Emission Reductions

3. “A car which run on alternative fuel having zero emission.”

4. Hybrid Cars
•Hybrid electric vehicles (HEVs) include two engine.
•If we had better batteries, we would not need hybrids at
all.
•Electric-gas hybrid, Solar-gas hybrid, electric combustion
engine hybrid and hydrogen-electric hybrid are the some
examples
•Hybrids can be implemented in many kinds of vehicles.
•Hybrids are not zero-emission vehicles.
•Will cut down emissions of global-warming pollutants by
a third to a half.
•Later models may cut these emissions down by even more.

5. •Fuel efficiency is greatly increased (twice).
•Emissions are greatly decreased.
•Dependency on fossils fuels can be decreased.
•Hybrids can be run on alternative fuels as well.
•New materials can be implemented.

6. Honda Civic Hybrid
Toyota Prius

8. Good:
• More energy rich per kilogram than petrol or battery-
powered electric cars
• Produces only water as exhaust
• Refuels faster than electric cars
Bad:
• Very expensive to produce
• Difficult to store and transport
• Incompatible with current infrastructure

9. What is a hydrogen fuel cell?
•Hydrogen fuel cells (HFCs) are a type of
electrochemical cell.
•HFCs generate electricity by reduction
and oxidation reactions within the cell.
•They use three main components, a
fuel, an oxidant and an electrolyte.
•HFCs operate like batteries, although
they require external fuel.
•HFCs use hydrogen as a fuel, oxygen as
an oxidant, a proton exchange
membrane as an electrolyte, and emit
only water as waste.

10. How do they work?
•Fuel (H2) is first transported to
the anode of the cell
•Fuel undergoes the anode
reaction
•Anode reaction splits the fuel
into H+ (a proton) and e-
•Protons pass through the
electrolyte to the cathode
•Electrons can not pass through
the electrolyte, and must travel
through an external circuit which
creates a usable electric current
•Protons and electrons reach the
cathode, and undergo the
cathode reaction

12. Uses of hydrogen fuel cells
There are many different uses of fuel cells being utilized right now. Some of these
uses are…
•Power sources for vehicles such as cars, trucks, buses and even boats and submarines
•Power sources for spacecraft, remote weather stations and military technology
•Batteries for electronics such as laptops and smart phones
•Sources for uninterruptable power supplies.

13. SOLAR FUEL CAR
GOOD:
•Use solar power.
•Zero emissive vehicle.
•Free source of energy.
•Renewable source of energy.
BAD
•Expensive source
•Weather dependent
•Less efficiency
•Only depend on day

15. EXAMPLES

16. AIR CAR
 Air Car- Powered by Air Engine.
 Having Emission Free Piston Engine using Compressed Air as Fuel.
 Gasoline- Main source of Fuel, Very Expensive and Impractical
(Environmental Standpoint), Non- Renewable resource, it will eventually run
out.
 Air Powered Cars runs on Compressed Air instead of Gasoline.
 Powered by two cylinder compressed engine.

17. •Long storage lifetime Of Air.
•Potentially lower initial cost than battery electric vehicles when mass
production takes place.
•A Pure Compressed Air Vehicle produces no pollution at the tailpipe.
•The compressed air engines also offer drivers the option of using fossil fuels or
bio-fuels to heat the air as it enters the engine.
•Air cars are lighter than conventional cars.
•When Compressor runs on Gasoline, it will create Pollution.
•One-to-two hour Waiting for the Car's built-in Air Compressor to Compress air
could become a problem on cross-country trips.
•The distance that an Air Car can cover without refueling is crucial because very
few filling stations will have compressed air pumps available.
