Testing artificial photosynthesis

With the daily mean concentrations of atmospheric carbon dioxide having reached 400 parts-per-million for the first time in human history, the need for carbon-neutral alternatives to fossil fuel energy has never been more compelling.

Towards a deeper understanding of dark matter

Most of the matter in the universe may be made out of particles that possess an unusual, donut-shaped electromagnetic field called an anapole.

Reducing pollution in cities with electric cars

One thing we’ve come to expect with the rise of electric vehicles is that pollution levels in areas where these are driven will drop, even if just slightly.

Hybrid wind turbine goes solar

Go big or go home, right? That seems to be the thinking at the University of Bath, which has headlined a report on a new renewable energy device design with the not-so-timid claim: “New hybrid technology set to change the future of renewables.”

Mission electric motorcycle hits 150 MPH

Those looking to get into high end, high performance electric motorcycles apparently need look no further than Mission Motorcycles.

Hydrogen fuel cells eyed for electric bikes

Electric bicycles, despite being a very green form of personal transportation for those who can’t live without some type of motor assist, can still sometimes run into the same problem electric cars do when it comes time for charging.

Researchers eye next-gen lithium-ion batteries

Laptops could work longer and electric cars could drive farther if it were possible to further increase the capacity of their lithium-ion batteries. 

This wireless audio Rukus is solar powered

It wasn’t that long ago we reviewed the Etón Rukus Solar, a portable Bluetooth sound system powered by the sun. The company is now back in our headlines with word of a new, even more high end solar boombox dubbed the Rukus XL, pricing for around $200.

Ancient trapped water may explain Earth's first ice age

Tiny bubbles of water found in quartz grains in Australia may hold the key to understanding what caused the Earth's first ice age.

Solar gardens grow across the US

If you’ve got a giant tree that shades your house on sunny afternoons, good for you; you’ll stay nice and cool this summer. Of course, there is a downside to such a situation – one shared by apartment dwellers: You can’t go solar.

Tesla Motors preps deployment of supercharger network

Tesla Motors continues to look to make it easier for owners of its vehicles to enjoy free, long distance driving in parts of the U.S. and Canada through its expanding Supercharger network.

Is this the grid of the future?

An 8,000-square-foot, nondescript, two-toned box of a building in Salem, Ore., looking like so many you’d see in a thousand industrial parks, could represent the future of energy management.

Cheaper, "greener'" lighting with inkjet-printed hybrid quantum dot LEDs

We all know It's not exactly easy going green. For home lighting applications, organic light emitting diodes (OLEDs) hold the promise of being both environmentally friendly and versatile.

The "World’s Tallest Tower" may be the greenest

When most super-tall skyscrapers are built, they are the crown jewels of the skylines in each city – acting like an exclamation mark on their perceived world status. With a newly proposed tower that is scheduled to begin this month in China, the skyscraper itself will be the skyline.

This bulb is powered by algae

Not content with CFLs or LEDs? Looking for an even greener way to light up your life? Hungarian designer Gyula Bodonyi’s “AlgaeBulb” concept might be right up your alley.

Ultrasound 'making waves' for enhancing biofuel production

All chefs know that "you have to break some eggs to make an omelet," and that includes engineers at Iowa State University who are using high-frequency sound waves to break down plant materials in order to cook up a better batch of biofuel.

Novel silicon electrodes improve lithium-ion batteries

Stanford University scientists have dramatically improved the performance of lithium-ion batteries by creating novel electrodes made of silicon and conducting polymer hydrogel, a spongy material similar to that used in contact lenses and other household products.

How to move geothermal drilling forward

You might think of it as the, “How to Get Geothermal Over the Risk-Hump Plan.” The idea is to establish a global exploration drilling fund, ideally with some public sector support. What good would it do?

Volvo tests electric roads

Battery conundrums continue to be a major road block for electric vehicles. They’re big, heavy, limit range, and although there’s less pollution coming out of an EV’s tailpipe, charging that monster battery still utilizes fossil fuels.
