    My green energy concepts

    By sketchy J 5.11.2008

    My name is Jason Kelso and i'm an engineering student at Metropolitan State College of Denver. I was recognized by the school recently for my idea "The Traffic Wheel", which uses the gravity of cars for industrial power production. I've also developed a model for a home system which would use the same principles of harnessing the gravity of cars for electrical energy. I'm hopeful I can develop a home system as a new home option for between $15 to $30K. Please look at my concepts for these at jaso888n.deviantart.com
