Our Group Idea : Solar Powered Cars
Solar Powered Cars
Solar powered cars, unlike other ordinary cars, make use of the energy from the sun to move. By using energy from the sun, harmful gases are not produced and emitted into the atmosphere unlike cars running on gas. It is very environmental friendly and does not add to the greenhouse effect. If the whole world changes to solar-powered cars, it would save the Earth from up to 72% of nitrogen oxides and 52% of reactive hydrocarbons.

Here are some pro’s and con’s about Solar-powered cars, based on WIKIPEDIA.
Pros :
-Solar-powered cars do not harm the Earth
-Solar-powered cars make use of Light energy, hence, gas is not needed.
-Solar-powered cars, on the long run are more cost effective.
Cons : ( based on a Swiss project “Solartaxi” )
-A maximum 400Km range without stopping
-Only a maximum speed of 90KM/h, while traveling on highways, it might have problems.
-Unable to use in rainy days, or at night, where light is absent.
We have also finished our Survey Questions :
Q1. Are you aware of global warming? Yes
No
Q2. Are you trying to reduce global warming?(If No, Proceed to Q4) Yes
No
Q3. In a scale of 1-5, how active would you rate 1 2 3 4 5
yourself on fighting global warming?
Q4. Do you think using Hybrid/Electric cars are Yes
effective in fighting global warming? No
Q5. Would you install solar panels in your house if you could? Yes
No
