| "In my poster, I used five examples of environmentally safe energy. At the top of the picture I drew wind mills powered by non other than wind. Below them, I put a stream in which a water wheel was placed. The rushing water turns the water wheel which turns other gears, creating energy. On the road, I drew a car powered by hydrogen. I made the house heated by natural gas from the underground gas pipe. The house was also lighted by solar panels." |
