Solar Car

Solar CarMembers :Tan Mao RongVincentChaiAbstractNow, fossil-fuels are decreasing by the days.Most transportation need fossil-fuel to run.Fossil-fuel was estimated to last for few more decades by scientist.Need alternative sources of energy and renewable to replace fossil-fuel.Solar energy is discovered and invented solar panel as sources of electrical energy.Solar energy is renewable energy, eco friendly and dont cause any pollution.This will reduce the uses of non-renewable energy and reduce earth pollution.ObjectiveTo invent ground transportation that use solar energy.To create eco friendly source of energy to replace fossil-fuel.To avoid pollution and improve earth ecosystem.To avoid decrease in fossil-fuel.To reduce cost.To create new invention out of solar energy.Solar Car specificationMotor and solar panel.Aerodynamic shape.Strong and Stiff body.Strong and Stiff material.Traction of wheel.Strong axle.Good transmission.

Solar panelThe solar panel need light energy to produce electrical energyThe solar panel is connected to the motor in the carIf the light intensity is high, the power of motor will be high.The relationship between light intensity is directly proportional to the power of motorAerodynamic shapeTo reduce air resistance.To cut through wind.To increase car speed.

Air flow smoothly

Strong and Stiff BodyTo able to maintain heavy mass.Unable to break or bend.Use ice cream popsicle stick to increase stiffness.Ice cream popsicle stick to increase stiffness and strongStrong and Stiff materialUse Styrofoam.Strong and stiff material.0.5 cm thick and unbendable when stack.

Traction of wheelUse sponge material for wheel.Have more traction and friction between surface and surface of wheel.Prevent sliding between car and surface.

Strong axleWheel and axel wont bend.Used metal to prevent from bend or break.

Strong Axle and wont break easily.Type of WireUse copper as wire.Cause it have less resistance.Thick diameter to increase current flow.

Copper wire and thick in diameter.Solar car velocityVelocity = distance travelled Time taken
