DIY Eco-Tech: Time to Vote

It was hard work to pick only three of the great entries in our DIY Eco-tech Contest, but here they are. Thank you to everyone who entered, and congratulations to the final three. Now, it is time for you to vote for the best Eco-tech innovation. After all of the effort that went into each of these entries, all you need to do to show your recognition is to pick and click your favorite. In order to prevent e-ballot stuffing, please only one vote per person.
