New York City turns to sewers for energy solutions
Listen up New Yorkers, those hot nuts you just swallowed could be used to light the signs on Broadway. Okay, so that's a stretch, but the city's Department of Environmental Protection (DEP) just issued a plan to turn the stuff you flush, along with rest of its wastewater, into renewable energy. New York City produces about 1.3 billion gallons of wastewater daily, yielding 1,200 tons of biosolids that can be harvested to procure methane -- already accounting for 20 percent of the city's energy -- and butanol, a clean gasoline alternative. The plan, which also includes wind and solar projects, aims to use gas, converted by large digesters, to "power wastewater operations, meet on-site heat and electricity needs, and, where feasible, sell excess energy to the market." As the DEP points out, the plan isn't far fetched -- we've seen a couple of solutions for turning human excrement into usable energy, and a project already under way in Greenpoint is estimated to procure enough methane over the next year to heat 2,500 homes. Now, if that doesn't give you a newfound respect for the porcelain throne, we don't know what will.
Intel's experimental sensor analyzes appliance power consumption from single outlet
It's pretty much set in silicon -- in the future, you will monitor your home power consumption, and perhaps even enjoy doing so. Futuristic touchscreen panels and free monitoring software abound, each designed to reward you with a warm, fuzzy Captain Planet feeling and a reduced energy bill when you finally turn off that blasted light. Thing is, unless you've got a home automation system, you won't know which switch to flip. Intel wants to change that with a new wireless sensor that can identify each individual appliance in your house by their unique electrical signal, just by plugging into a single outlet in your house. The reportedly low-cost sensor works by simply recognizing voltage drop patterns when devices are turned on and off, and doesn't require special appliances to function; Intel demonstrated it on a standard toaster, microwave and fridge in Beijing this week. Demonstrate your supreme demand for this "why didn't I think of that" idea by directing traffic to our source link -- you can jump to 20:10 to see the sensor in action. Update: Come to think of it, that looks just like a wireless version of Marvell's SheevaPlug.
Earth Hour starts at 8.30PM tonight, asks for sixty minutes of natural living
Time to don your eco-warrior armor, strap on your nature-loving helmet, and flick that big old... light switch. Yes, in honor of the WWF's Earth Hour, countries around the globe are tonight switching off non-essential lights and appliances for sixty minutes, with highlights including Big Ben, the Eiffel Tower, the Burj Khalifa, and the Empire State Building all going dark in the hope of helping the planet stay green. Timed for 8.30pm your local time, this unorthodox event has already commenced with Australia, New Zealand, China and others doing their bit -- videos after the break -- and is just now hitting Eastern European borders. So, fellow earthlings, will you be among the projected one billion souls that go au naturel for an hour tonight? [Thanks, Pavel]
Silverstat7 Zigbee-packin' thermostat to debut this fall for $600?
Every day it seems that companies are finding better ways to keep an eye on the non-renewable resources we're sucking down to enable our voracious appetite for Xbox gaming and Hulu viewing. Not that we're complaining! And now, thanks to a gracious tipster, we've received some deets on that Silverstat7 home energy management solution (er, touchscreen thermostat) we first hepped you to a couple days ago. Along with 802.11g WiFi, this guy supports the Zigbee and Zwave protocols (as you probably guessed), so it should be able to play nicely with your existing smart meter, switches and outlets. Earlier reports of a June 2010 release date may have been premature -- look for it this fall for about $600 MSRP. [Thanks, Tony L.]
Silverpac Silverstat 7 provides energy usage data, responds to touch
Boy, if it's not car dashboards, it's thermostats -- you just can't get away from touchscreens these days. The latest 7-inch temperature regulator from Silverpac comes with a bunch of extra goodies to entice the touch control-loving generation into the energy conservation game. With WiFi built in, the Silverstat 7 can pump data out to the internet or your home network, and is equally adept at streaming photos, music and other content back from those connections. A full week's worth of water temperature instructions can be programmed into the device, which can also inform you of weather conditions and your home's energy consumption. The latter part is most intriguing, as you'll be informed of power usage on a per-appliance basis, which can be mighty beneficial when a certain bit of home hardware gorges on electricity without you knowing. June 2010 is set as the release date, but the wallet damage remains unrevealed.
Power Up - educational game from IBM
It's hard to be sure how to file an article about Power Up - particularly since I can't actually play it, it's a windows only game. But, from what I can determine it seems to be a multi-player game, it's role-playing, and it's aimed at energy conservation and ecological education. There are sections available for teachers and parents as well as fun mission briefings and the promise of more to come during the year.In some ways this game strikes me as a retrograde step: rather than using something like Active Worlds or Second Life which many regard as Web 2.0 since there are tools for content creation and sharing, we have a very focussed programme that teaches one thing and only that one thing. All the content is provided in a Web 1.0 fashion: by IBM, TryScience and the NY Hall of Science rather than allowing the users to create for themselves. However, we wish it well and will try to keep an eye on it for you.[Via: Virtual Worlds News]
Energy saving power-strip cuts the waste
French designer Gilles Belley has come up with an ingenious concept for power distribution and conservation, simply called the "Energy Saving Adaptor". The system uses modular plugs which link together to form a power-strip of connectors, these hang from the side of a desk (where they can be added or taken away as necessary), and each module monitors the energy status of a single device and displays that information via blue LED lights on the surface. When a connected device goes into "standby" mode, the lights alert the user, and within three minutes the module automatically shuts down, thus conserving otherwise wasted energy. Additionally, these modules look roughly a thousand times better than the power-strips we've all been buying at the dollar store, which never hurts. No word yet on when or if these will be made commercially available.[Via Akihabaranews]
Taiwan switching to LED traffic lights
Taiwan, always known to one-up the global marketplace when it comes to traffic control and street lighting, has announced that within the next three years all of its traffic lights will become LED based. The country's Ministry of Economic Affairs (MOEA) has budgeted roughly NT$229 million ($7 million) for the project, which is set to begin in 2008, and will convert 420,000 traffic lights to the LED standard (350,000 have already been changed over). The MOEA claims the total savings in power consumption will be close to 85%. After the sweeping reform of its traffic signals, Taiwan will invest another NT$130 million to swap its street lights out for LED-based models. Nations of the world, the gauntlet has been thrown down.[Via Digg]
