A PRESENTATION ON“FUTURE OF CARS” AND “ITS FUEL” PRESENTED BY: AMBESH SINGH ME 4th YEAR
• Petroleum Displacement• Depleting Non renewable Energy• Air Quality Improvement• Greenhouse Gas Emission Reductions
“A car which run on alternative fuel having zero emission.”
Hybrid Cars•Hybrid electric vehicles (HEVs) include two engine.•If we had better batteries, we would not need hybrids atall.•Electric-gas hybrid, Solar-gas hybrid, electric combustionengine hybrid and hydrogen-electric hybrid are the someexamples•Hybrids can be implemented in many kinds of vehicles.•Hybrids are not zero-emission vehicles.•Will cut down emissions of global-warming pollutants bya third to a half.•Later models may cut these emissions down by even more.
•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.
Good:• More energy rich per kilogram than petrol or battery-powered electric cars • Produces only water as exhaust • Refuels faster than electric carsBad:• Very expensive to produce • Difficult to store and transport • Incompatible with current infrastructure
What is a hydrogen fuel cell?•Hydrogen fuel cells (HFCs) are a type ofelectrochemical cell.•HFCs generate electricity by reductionand oxidation reactions within the cell.•They use three main components, afuel, an oxidant and an electrolyte.•HFCs operate like batteries, althoughthey require external fuel.•HFCs use hydrogen as a fuel, oxygen asan oxidant, a proton exchangemembrane as an electrolyte, and emitonly water as waste.
How do they work?•Fuel (H2) is first transported tothe anode of the cell•Fuel undergoes the anodereaction•Anode reaction splits the fuelinto H+ (a proton) and e-•Protons pass through theelectrolyte to the cathode•Electrons can not pass throughthe electrolyte, and must travelthrough an external circuit whichcreates a usable electric current•Protons and electrons reach thecathode, and undergo thecathode reaction
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.
SOLAR FUEL CARGOOD:•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
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.
•Long storage lifetime Of Air.•Potentially lower initial cost than battery electric vehicles when massproduction 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 orbio-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 Cars built-in Air Compressor to Compress aircould become a problem on cross-country trips.•The distance that an Air Car can cover without refueling is crucial because veryfew filling stations will have compressed air pumps available.
