We are happy to announce the winner of our Go Green contest, thrown over on Instructables with the help from our friends at TreeHugger. The winning project details an ingenious way of further purifying the effluent water output of a sewage treatment tank (also designed by the contest winner's organization) and using it to grow plants in a hydroponic garden. Well done! Stay tuned here for more of our favorite entires, published in their step-by-step glory. Congratulations and thanks to all who entered! —John Mahoney
