1Just when I start to worry about the fate of the world,along comes a new generation of innovators who are making big changes in the way things are done.
Nikita Rafikov
2Nikita is young,but he has big plans for the future,and he has the ideas to get him there.The 11-year-old developed a way to embed（嵌 入）Green Fluorescent Proteins（GFP）into windows to create efficient lighting.GFP is the protein found in certain jellyfish that creates those cool bioluminescence (生物发光) effects seen in nature photography.By embedding this protein into windows,Rafikov has found a way to light homes without the use of electricity.
Lynnae Shuck
3After a positive volunteer experience at a nearby wildlife refuge,Lynnae wanted to find a way to teach more kids the role of refuges and give them more opportunities to help preserve them.So she carried out the Junior Refuge Ranger program where kids aged 8 to 11 participate in labs,habitat hikes,and birding expeditions to learn about conservation,endangered species protection,habitat restoration,and environmental awareness.
David Cohen
4David Cohen's big idea is the perfect example of how creative kids can be when they are allowed to think outside the box.Cohen was learning about earthworms in science class when he wanted to build a robotic earthworm,after which he wrote the code behind a prototype robot.By loading the robot with heat-sensing technology,GPS,and other life-saving programs,Cohen's robot could be used to find and rescue people safely and efficiently.
Jai Kumar
5Jai likes to invent things,especially things that provide simple solutions to everyday problems.The 12-year-old middle-schooler has created a gaming system for the senior as well as an automatic light dimmer（自动变光装置）that senses sound levels in the school cafeteria.But what landed him on this list of eco-innovators is his window-mounted solar-powered air filtration device designed for developing countries where air pollution is very high.The device uses inexpensive components to purify the air before it enters the houses.
