I love it when someone sees two problems and puts them together to form a solution. This innovative homeowner installed a system to his air conditioner to tap the waste water and divert it to his garden. The beauty of the system? When it gets hotter, the air conditioner runs more often and waters the parched plants. The homeowner has detailed instructions on the setup on the Web page. If you do something similar, let us know in the comments.
