How We Could Save the World From Global Warming Before Our Time Is Up

How We Could Save the World From Global Warming Before Our Time Is Up

We’ve blown our chances of fully counteracting the effects of climate change; recently-released reports from the International Energy Agency and the UN Environment Programme (UNEP) provide plenty of evidence. But all hope is not yet lost, we’ve still got a small chance to keep from irreversibly poisoning our atmosphere. Here’s what the world’s governments must do to save the Earth before we cook ourselves clean off the face of the planet.

GE’s Wind Turbine Tester Puts Gigantic Drivetrains Through Hell

GE's Wind Turbine Tester Puts Gigantic Drivetrains Through Hell

Modern multi-megawatt wind turbines are downright gargantuan, standing more than 700 feet tall with 260-foot blades spinning 190 mph at the tip. To make sure that these monolithic machines are up for 20 years of energy production, GE has created a tortuous test bed capable of sucking 20 years of life from a turbine in a matter of months.

Floating Generator Transforms the Ocean’s Motions into MegaWatts

Floating Generator Transforms the Ocean's Motions into MegaWatts

While winds may die and clouds may obscure the sun, nothing can stop the rhythmic lapping of ocean waves. Now, an Australian company hopes to harness that power and covert it to usable electricity with the most powerful wave-energy generator ever created. And this is just their small-scale prototype.

How to Sun-Cook a Steak in South Africa

Consistent electricity is more guideline than rule in South Africa, even on the outskirts for the capital city of Johannesburg. This ambiguity leaves residents either living in the dark or at the mercy of expensive and hazardous kerosene- or coal-based fuels. One social entrepreneur however, has a plan to provide clean, safe, nearly free energy to even Johannesburg’s poorest citizens.

America’s most sustainable city: A green dream deferred

America's most sustainable city

It sounds like the future. Whirring electric skateboards, the joyous chatter of children in a distant playground and an unusual absence of petrol-powered machinery. It looks like the future, too. Glistening lakes dotting the background, lawns so lush they’re mistaken for artwork and an unmistakable reflection from a vast solar farm that doubles as a beacon of unending hope.

The reality, however, is starkly different. The depictions here are mere conceptualizations, and the chore of concocting the most Jetsonized habitat this side of Orbit City is daunting in every sense of the word.

The Army’s Got a Fuel Cell That Runs on Corn Husks and Old Bullets

The Army's Got a Fuel Cell That Runs on Corn Husks and Old Bullets

The Iowa Army Ammunition Plant (IAAAP) in Middletown, Iowa has an overabundance of two things: corn waste and excess energetics—leftover explosives, propellants, pyrotechnics and such. But using a new ethanol-based fuel cell developed by nanoMaterials Discovery Corp (nMDC) will transform these waste materials into clean, cheap, electricity. Two birds, one catalytic reaction.

How to Inspect Windmill Blades Without Ever Leaving the Ground

Getting to the top of a wind turbine is no small feat—akin to summiting the Washington Monument—and even more difficult when the wind farm is at sea. So rather than force human inspectors to make the perilous climb, Helical Robotics has developed a magnetic turtle to do it for us. More »
