COOL INVENTIONS

From school to band Practice, the Venturi Eclectic is an 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 on renewable energy．Solar panels on the Eclectic's roof absorb sun rays when you're driving．On windy days, you can connect a machine to the car's roof that collects energy from the wind while you're parked．The Eclectic's top speed is 28 miles an hour; the battery lasts for 31 miles before it needs to be recharged．Zipping (迅速行进) around the neighborhood has never been better.

Here's an eco-friendly way to tell time: Simply fill the Bedol Water-powered Clock's tank (箱) with water, add some lemon juice, and the clock will display the time without the need for environmentally 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 ions complete a charge between the electrodes, creating enough energy to power the clock．Just refill the tank every few weeks, and this clock will keep on ticking.

Bloodhound SuperSonic Car (SSC) will be the first car to attempt to break the l,000-mile-an-hour barrier．(The current record is 763 miles an hour.) A concept for now, the rocket-shaped car gets its initial push to 350 miles an hour from a jet engine．Then a rocket fires up, pushing the SSC past 1,000 miles an hour．In order to keep the car streamlined (流线型的), the driver lies back at a 45-degree angle.

You're having a blast at your friend's birthday party．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 clever camera captures the view from above．The Triops can take three pictures at once, each from different angles．You can also record sounds and command the Triops to start shooting whenever it hears that noise．That's one smart camera.
