From school to band practice, the Venturi Eclectic isan Earth-friendly way to get where you want to go. This battery-powered,zero-emission (meaning it doesn't pollute the air) vehicle runs mainly onrenewable energy. Solar panels on the Eclectic's roof absorb sun rays whenyou're driving. On windy days, you can connect a machine to the car's roof thatcollects energy from the wind while you're parked. The Eclectic's top speed is28 miles an hour; the battery lasts for 31 miles before it needs to berecharged. Zipping (迅速行进) around the neighborhood has never beenbetter.

Here's an eco-friendly way to tell time: Simply fillthe Bedol Water-powered Clock's tank (箱) with water,add some lemon juice, and the clock will display the time without the need forenvironmentally harmful batteries. There are two sets of metal electrodes(电极) inside the water tank. Water contains ions (离子) that carry negative and positive charges. These ionscomplete a charge between the electrodes, creating enough energy to power theclock. Just refill the tank every few weeks, and this clock will keep onticking.

You’re having a blast at your friend’s birthdayparty. But when it's time to bring out the cake, everyone crowds around,blocking your view. No worries. Throw the Triops into the air, and this clevercamera catches the view from above. The Triops can take three pictures at once,each from different angles. You can also record sounds and command the Triopsto start shooting (拍摄)whenever it hears that noise. That's onesmart camera.
