Green Technology

Green technology is technology that produces clean energy, helps repair environmental damages or offers solutions to wasteful practices.


In Colorado, a recycling robot uses artificial intelligence to sort through discarded cartons more efficiently.

China, the world's largest emitter of CO2, is making steps to combat those emissions by creating the world's largest floating solar panel farm.

Some scientists are proposing a massive array of wind-powered pumps to bring more Arctic water to the surface, so it can freeze and thicken existing sea ice.

A French company has created a miniature wind turbine that looks like a tree and could provide enough energy for a house.

The big problem of cleaning water quickly and cheaply might just have been solved, thanks to this tiny gadget.

And they're ready to help you do it, whether it's just you, your school, your company or your neighborhood.

Scientists are tickled pink about all the environmental uses for the orange peel.

Drones and other unmanned flying machines are going green.

These days, it seems everyone is "going green." From individuals to businesses, everyone is looking for ways to be more sustainable and environmentally-friendly. But is green tech the way of the future or just another fad?

We live in an age when DIY has taken on exciting, nerve-wracking connotations. Add in some knowledge and some money from crowdfunding sites like Kickstarter, and you have a recipe for a transformed world. Will glow-in-the-dark plants be a part of it?

As far back as 1500 B.C.E., people were trying to purify water to make it drinkable. And we're still at it. Today inventors use tools as simple as clay and as sophisticated as carbon nanotubes to bring clean water to the world.

Imagine a different kind of light bulb, one that lasted as long as a fluorescent bulb, but without the buzz, as energy-efficient as a CFL but with a more pleasing light. Meet the FIPEL bulb.

The rising cost and projected scarcity of fossil fuels has people talking. But finding a new power source and developing an infrastructure will be costly and challenging. Will we still be using gasoline in 2050?

We live in a universe of clocks. The technology may not sound as dependable as your cell phone alarm clock, but humans have turned to water-powered clocks for more than three and a half millennia.

Electronics use a lot of juice. So what's an environmentally responsible citizen to do? Going solar might just be the answer.

There is no accepted standard of what makes a "green" gadget. With that in mind, here are five devices that do not use any energy at all or that find novel ways to rethink a common gadget while also making environmental improvements.

If you're like most folks, you spend a few hours a day on the computer. What changes can you make to save power without compromising the way your work?

When you take a shower, the hot water moves quickly from the showerhead down the drain. What if you could reclaim that wasted heat to warm up new water?

If you turn off the lights in your computer room, you'll probably see the glowing eyes of vampire electronics peering back at you. A smart power strip can help you cut down on how much energy they waste.

For plenty of people, getting a drink of water on the hottest of days is not as easy as filling a glass at the tap. The Slingshot aims to do something about that.

While you shouldn't expect to find a "flying electric" option at the airport anytime soon, electrically powered aircraft not only exist, but the technology continues to evolve at an encouraging rate.

While many of us are phasing out our incandescents for CFLs one bulb at a time, there might be a third contender on the market soon enough. LEDs are making the shift from your headlights to your bedside lamps.

Solar air conditioners take advantage of the sun at its brightest and use its energy to cool you during the hottest part of the day. What are we waiting for?

What if your net power usage was zero? Some homes combine energy efficiency with their own power plants to end up consuming no energy at all.

Imagine finishing off a nice cup of morning coffee and then, instead of throwing the grounds into the trash, pouring them into a cartridge where they become printer ink.
