Wind power breakthrough: Carbon nanotubes make strongest, lightest blades ever

Bigger wind turbines can harvest more wind energy, but they're also heavier, which makes them less efficient. But a scientist at Case Western Reserve University figures he can solve this fundamental dilemma by throwing carbon nanotubes at it.  

Panda poop could revolutionize biofuels

One down side of biofuels like ethanol is that they rely on easily processed crops that are also staple foods. The more farm space is given over to raising corn, soybeans, and sugar for fuels, the less is available for raising those crops to feed humans. Luckily, scientists have just discovered microbes that could help turn waste plant matter like corn stalks and wood chips into fuel. All they needed was a little bit of panda poo.

How the smart grid of the future will prevent power outages for millions

Right now there are millions of people without power thanks to the wind and heavy rainfall that accompanied hurricane Irene, and I'm one of them. It sucks. Having to call the utility company just to let them know that they've failed me once again is a symptom of our antediluvian electricity distribution system. 

Commonwealth Edison of Northern Illinois thinks so, too. Recently, they explained to the Daily Herald how a smart grid would have prevented outages for hundreds of thousands of their customers in the wake of recent July storms.

How to get paid to save the electrical grid

On the hottest days of the year, it's not uncommon for regional electricity systems to become so overloaded by demand that they come within a hair’s breadth of failing completely. (It happens in Texas all the time.)

Fortunately, utilities have come up with a cheap and easy way to overcome this problem: they offer their customers a cash incentive to sign up for a special kind of thermostat over which the utility has limited control. Then, when it gets nasty out, the utility can literally save the grid by turning up the temperature in your home just a teeny tiny bit. This is what's known as "demand response."

Fracking sadface: U.S. has one-fifth the shale gas once projected

"Oops," says the United States Geological Survey, "We used to think the shale on the East coast of the U.S., which gas companies are currently fracking into submission, had a metric buttload of natural gas. Turns out it only 0.2 metric buttloads." (I'm paraphrasing.)

Poop-fueled batteries could clean water while generating energy

If there's one thing humans can apparently generate an endless supply of, it's shit. So why not use that to produce things we need but don't have enough of, like clean water and energy? Environmental engineer Bruce Logan is developing fuel cells that may be able to do that, cleaning wastewater while generating and storing energy.

Number of electrified vehicles to increase 4,500 percent in six years

By 2017, there will be 5.2 million plug in hybrid and all-electric vehicles on the road worldwide, says Pike Research. Add in 8.7 million hybrid vehicles, and the total population of electrified autos in the world is set to increase 46-fold from the measly 114,000 that currently ply our roads. Despite this explosive growth, that […]

Taste of things to come: Texas drought to shut down power plants

Hey, you know what's wild about Texas turning into a gigantic desert thanks to climate change? I mean besides the fact that this makes it basically Kuwait-on-the-Rio-Grande? Many of the state's power plants, which rely on fresh water to produce electricity, could be shut down by the lack of water.

The trucks of the future will have skirts, tails, and fins

This month, the White House announced the first-ever fuel efficiency standards for heavy trucks — heavy pick-ups, work vans and trucks (think the Frito-Lay delivery guy), and tractor-trailers. The people who make these behemoths have never had to think about fuel economy before, but now they do. And there's lots of room for improvement.

Critical List: Hurricane Irene headed for East Coast; EPA totally creates jobs

East Coasters may not know what do in an earthquake, but a hurricane's coming, too. That, we know about.

The Obama administration is looking into "leasing" nuclear fuel from other countries, which would let American plants use the uranium, then return it for disposal once the fuel is spent. It’s like a bottle-return program, but with much higher stakes.

Chinese consumers want cars, not those namby pamby EVs.
