Somehow, Los Angeles Tops EPA's Most Energy-Efficient City List


An unlikely trio of cities can lay claim to the United States' most energy-efficient buildings, thanks to a report in USA Today.

Los Angeles, San Francisco, and Houston have been named by the EPA as having the most efficient buildings in the U.S., with annual energy savings of $87.2 million, $83.8 million, and $70.6 million, respectively.

While we would love to jump on the bandwagon and slap these three cities on their backs, we have a little bit more sense than that. After all, anybody who has visited Los Angeles and Houston is well aware that these two places aren't exactly "green." They are, however, massive cities, not only in population, but in sheer geographical sprawl, as well. So, of course, each of these cities has more green buildings than Cheyenne, Wyoming, or Hattiesburg, Mississippi, or Lancaster, Pennsylvania. But that's because they have a lot more buildings, in general.

And while some of those buildings may be green, most of them aren't. We're not exactly students of the environment, but we're certainly confident in saying that Cheyenne, Hattiesburg, and Lancaster -- all put together -- have less of a negative environmental impact than Los Angeles alone.

When Exposed to Sunlight, These Clothes Clean Themselves

Could this mean the end of laundry day? Textile scientists in Australia and Hong Kong have developed a special coating for fabrics made of titanium dioxide nanoparticles that actually cause the fabric to self-clean when exposed to sunlight.

Besides the obvious benefit of less time spent doing laundry, the new fabric could also mean less water used to wash clothes and less detergent being washed down drains -- both of which are good for the environment.

Wine stains diminished during the course of a day.When hit by direct sunlight, the nanoparticles -- specifically Keratins, a class of biologically fibrous proteins -- begin to interact with oxygen in the air, breaking down stains and dirt. According to a report on the scientists' findings in the science journal Chemistry of Materials, red-wine stains on pieces of wool started to fade within a few minutes of exposure to light and had all but vanished within a day (see the time-elapsed test here).

Supposedly, the nanoparticle coating does not affect the feel of treated clothing, but it may make the clothing less durable over time. It could take about five years to refine the technology to make it ready for wide distribution and use.

Note: This does not mean you can stop bathing -- an important caveat, especially for the Switched.com interns.

NRG Dock Juices Up Gadgets When the Power Is Out




NRG Dock Powers Gadgets When the Power is Out

Three years ago Jay LeBoff got snowed in and lost power for four days. During that time, LeBoff was forced to rely on a cell phone as his only way of contacting the outside world for emergency purposes. But without power to recharge the phone, he would have been up a certain creek without a paddle if the battery gave out.

The experience, and a little bit of environmentally-friendly thinking, inspired LeBoff to design the NRG Dock, an emergency power source in three different styles, two of which are taking advantage of the renewed interest in solar power.

The NRG Dock Home comes in two separate parts, a large solar panel that charges a massive 12-volt battery capable of powering a laptop, and the NRG Dock itself, which has a variety of power adapters for phones, media players and other electronics, as well as a rechargeable flashlight.

The Apartment model has the same dock, but instead features a smaller, removable solar panel mounted on top. The Apartment model doesn't generate enough juice to power a laptop, though, and carries a smaller battery, but the lesser size means the solar panel can be mounted on a wider variety of surfaces, including the inside of the window.

The basic Designer dock has the same smaller battery as the Apartment model, but drops the solar panel in favor of a standard wall plug and functions purely as an emergency backup power source.

Currently the NRG Dock is in the prototype stage, but the company hopes to hit a target price of $800 for the Home model, $500 for the Apartment, and $350 for the Designer. The Home and Apartment models will also qualify for a 30 percent tax break from the federal government and may qualify for additional tax breaks in certain states.

Green Tech to be a Major Theme at Next Week's Gadget Show


green tech to be a major theme at cesNot like we couldn't see it coming, but news is that a big theme at this year's CES will be "green technology." The environment, being green, and global warming have been on everyone's minds this year. The Prius, 'An Inconvenient Truth,' OLEDs, and tons of research into alternative power sources and fuels were all the rage in 2007, and '08 doesn't look to be any different.

A number of new technologies are expected to make their debut, or at least US debut, at CES next week. Among them is a new Silver-Zinc battery technology that will increase battery capacity by up to 30 percent, and will also yield more recoverable metal when recycled than the currently common Lithium-Ion batteries.

Fujitsu will show off a laptop with a plastic case made partially from corn byproducts. The case will not be biodegradable, because it still contains petroleum based plastics, but when the case is recycled the petroleum based plastic mixed in with the corn will separate and the corn plastic will be biodegradable.

Even cell phone chargers are getting a green makeover. As much as two thirds of the power drawn by a phone charger is wasted because AC adapters continue to draw energy even after the phone is fully charged. A company called GreenPlug will show off a universal hub that it hopes to convince electronics companies to support. The hub works by "talking" to devices to determine how much power they really need. Another perk is that the universal hub could eliminate the need for carrying a separate adapter for every phone, iPod etc. However one very un-green side effect is that the hub, even if supported, just means more non-biodegradable plastic going into circulation.

Nintendo Ends Up On Bottom of Green Electronics List

Nintendo and Microsoft Dissed by Greenpeace, Sony Adored

Greenpeace has been making a lot of noise lately with its attacks on Apple for using nasty stuff in the iPhone and in general for not being very green. Apple is implementing plans for getting greener, and now it seems Greenpeace is moving on to, well, greener pastures, attacking a whole boatload of tech companies with its latest Guide to Greener Electronics.

The guide rates electronics manufacturers based largely on their commitment to recycling old gear and reducing the use of toxic compounds in new stuff. This is the first time Greenpeace has chosen to include Nintendo in the list, and it has ranked the Wii-maker dead last -- not because the motion-sensing abilities of the Wiimotes are powered by globs of toxic waste, but instead simply because the company doesn't provide any information about things such as what it's doing for recycling and when it plans to phase out the use of PVC.

Nintendo's competitor in the video game battle, Microsoft, is also new to the list and also scores low, though slightly better than Nintendo, thanks to having a plan for phasing out the use of PVC and other materials that result in the creation of toxic compounds. Sony, the third player in the current console war, scores much higher in the green rankings thanks largely to its acceptance of expired electronics from Japanese consumers for recycling.

We here at Switched find this ordering somewhat confusing. Sony's console, the PlayStation 3, is by far the most power hungry of the three, drawing 200-plus watts of electricity when playing games. Microsoft's Xbox 360 averages a somewhat more efficient 145 watts, while Nintendo's Wii uses just 15-20 watts, which is less than 10-percent of the power of Sony's machine! Yet Nintendo is ranked as the worst electronics maker on the planet? We think Greenpeace should care a little more about the pollution caused by power generation.

Top of the charts was Sony's celly spin-off Sony Ericsson, which has already phased out the use of PVC to a large extent, while most others are still just thinking about it.

Driverless Car Uses Lasers to Avoid Obstacles





Slowly but surely, the automated future that industrialization and science fiction have long promised is creeping up on us. And if reality is to be believed, automation might actually run us over (or shoot us) if we're not looking.

The BBC reports that an English town called Daventry is testing out a driverless car, controlled by a computer that -- drumroll please -- uses lasers to avoid obstacles. Essentially, they're just robotic cabs -- the cars are called by pressing a button along the route, and go directly to their destination.

The testing is part of Daventry's investigation into new ways to increase the use of public transport and reduce reliance on cars.

Running until October 5th, the demonstration is actually in effect for commuters looking to get from A to B within the town. The Cybercars are designed for short trips at low speed in an urban environment, and need only a very light track to operate -- think of them as a cross between a car, a trolley, and a golf cart.

As weird as it sounds, it's this sort of forward thinking that is going to bring us out of our current automotive stone age, since it could potentially reduce the amount of vehicles on the road (not to mention serve as a designated driver when party goers have had too much to drink). Daventry District Council leader Chris Millar said all: "We can build lots more car parks and have lots more cars going in or we can look at a viable alternative to the car. We believe this could be the answer."

Let's just hope the residents of Daventry are stocking up on laser-proof vests, lest one of these babies accidentally shoots a pedestrian/obstacle.
