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. 

You shouldn’t be able to buy soda with food stamps

The USDA has rejected New York City's proposal to block the use of food stamps to buy soda. Anti-hunger advocates joined the soft-drink industry in rejoicing, but they've got it all wrong.

Do your clothes contain toxic chemicals?

Chemicals in clothing can break down in water into hormone-disrupting nonylphenol (click the infographic to embiggen). If you want to avoid dumping this crap in the waterways, you have two choices: One, never wash your clothing -- which, on top of being gross, will probably not be that effective, since wastewater discharges from textile plants sluiced nonylphenol out into the waterways before your clothes even hit the store. Or two, opt for clothing from companies that don't use nonylphenol-producing chemicals (called nonylphenol ethoxylates, or NPEs). According to research from Greenpeace, though, that might be tough. Of the 15 brands they tested for NPEs, only Gap had zero positive results.

Critical List: Climategate scientist cleared; Halliburton exec drinks fracking fluid

The National Science Foundation found Michael Mann, a scientist at the center of Climategate, did nothing wrong. You don’t say.

Ford and Toyota are going to be working together on technology for hybrid trucks and SUVs.

Apparently Michele Bachmann wants to the United States to become an Iran-like state where oil is government-subsidized. How else to explain her continued, irrational insistence that gas will be $2 per gallon during her presidency?

One billion cars clog traffic worldwide

India and Brazil are also helping to accelerate worldwide auto sales -- and greenhouse-gas emissions.

The New York Times thinks the tar-sands pipeline sucks. Here’s why.

The New York Times has come out with an editorial position on the Keystone XL tar sands pipeline, and it’s unusually definitive, considering that we still have news media trying to represent “both sides” of the climate change “debate.” Here’s how they break it down.
