Is planet-cooling balloon full of hot air?

A stadium-sized balloon tied down by a giant garden house could mimic the cooling effect of volcanoes, say British researchers.

The greenest building on Earth

Workers broke ground this week in Seattle on a six-story building that will generate its own power, collect and reuse rainwater, compost its sewage, and depend on daylight instead of halogen lamps. Its owner, the Bullitt Foundation, which supports work in sustainability, set out to build the greenest building on Earth. We'd say they're earning that title. 

Biodegradable cigarettes: Because why should everything else die with you?

Just because your lungs are blackened doesn't mean you can't be green. San Diego-based company Greenbutts makes cigarette filters that not only biodegrade, but sprout when buried into what have to be the world's least healthy plants.

The dilemma of growth, as dramatized by the voices in my head

Is continued economic growth inevitable and necessary to drive improvements in the human condition? Or is continued economic growth impossible, constrained by biophysical limitations? I let the two sides battle it out in my brain.

China to build 50+ nuclear reactors based on unsafe 60's tech, says Wikileaks

"China is currently in the process of building as many as 50 to 60 new nuclear plants by 2020; the vast majority will be the CPR-1000, a copy of 60's era Westinghouse technology that can be built cheaply and quickly and with the majority of parts sourced from Chinese manufacturers," says this cable from the U.S. embassy in Beijing.

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.)
