Today we spoke about cars. N thinks they are so cool. A doesn't: all that polution simply to get to where you are going faster than if you walked. I mentioned that most people simply couldn't get to where they normally go by foot, but sure enough it would be better if they used some non poluting public transportation.
N suggested electric cars were the answer, but A pointed out that generating the electricity to charge the cars generated polution (I was impressed!). I told them about a recent article I read about some huge batteries that are being tested to store energy from wind turbines and solar cells.
I suggested we all start walking to school every day but they were not convinced...
