Hot Bodies to Heat New Office Building


Want to indian generic levitra keep your house warm without your furnace? A 30-person dance party is levitra without a presription pretty much the only way to do it. By the end of generic acetaminophen tramadol tablets the evening, you'll be opening windows.

Now imagine that your house is Stockholm Central Station, where 125,000 hot bodies hustle to and http://www.aldentheatre.org/viagra-tablets-for-sale from their commutes every day. All that body heat has traditionally been somewhat of a nuissance. But now, the city of Stockholm is actually going to capture the http://meivending.com/levitra-generico body heat and use it to heat a nearby office building.

Apparently the system is fairly simple. Just a bunch of pipes that will collect the heat, and pump it out of the too-warm train station and into a new office building being built nearby. Body heat from Stockholm Central Station will provide roughly 20% of the heat for the new building. For a system that will only cost about $30,000 to build, it's a no-brainer for the City of Stockholm.

Carectomy Week in Review

While here at EcoGeek we still celebrate advances in automotive technology, our friends at Carectomy.com take somewhat of a harder line. Carectomy is a resource for people who want to remove cars from their lives, and here's a sampling of this week's Carectomy stories.

Who Killed the Streetcars?


In the 1920s most people traveled by trolley and streetcar: One in ten were automobile owners. 88% of people polled after World War II wanted the streetcar lines expanded. GM, however, had other ideas.

London Makes Way for Car-Free "VIPs"


While Americans cruise crowded parking lots like buzzards, vying for the spot closest to the entrance, holiday shoppers in London’s West End are taking to buy tramadol ultram the streets--and leaving their cars at home. The result: a dramatic increase in business in this European shopping Mecca.

 

Arm-Powered Digital Camera from Sony


A while back we brought you one of canadian levitra scam visionwidget.com the first reports of Sony's ODO line of human-powered electronic devices. Well, now Sony has a working (though substantially altered) prototype of a human-powered digital camera. The device has a big ol' rubber wheel on the levitra 10 mg top that you push across any flat surface (or your forearm) to charge the batteries. About 15 pushes is enough for one shot, though presumably, you can push it a couple hundred times and then go off to the zoo.

It's fantastic to think that someday we'll be able to stop worrying about whether or not our batteries are dead, and I'd love to see this technology working its way into gadgets. For now, Sony is thinking about marketing the devices only to children. And as they're not going to compare with the slight size, ease of use, or any other feature of a modern digital camera, that's probably the right direction to go in.

There's no viewscreen (in order to viagra cheap canada save power), the pictures are fairly low quality, and there's no flash, of course. But I expect power usage to drop in all devices and for these kinds of elbow-grease chargers to start to make sense to consumers.

NRG PACK! Harness The Power Of Walking

One of our sibling blogs, Carectomy.com, just went into some detail discussing a new walker-powered backpack. The straps of the pack are made of a special material that can harness static electricity generated from the energy of walking.

My first thought is wow look it levitra no prescription that the energy from this action would be negligable in all situations, but Josh at Carectomy points out

A soldier carrying a 100-pound load and walking at 2-3 miles per hour would generate 45.6 milliwatts of power. To put this into context, an LED headlamp consumes about 38mW, an iPod nano 46mW, and a Motorola Razr cell phone 9mW in standby mode and http://www.intherooms.com/addiction/use-cialis 360mW while talking.

That's pretty impressive, actually. The only material necessary to generate the cialis generic online cialis generic power are the backpack's straps, which are made from polyvinylidene fluoride (PVDF), and possibly an onboard battery. Of course, the technology is a while away, but maybe someday we'll have whole wardrobes made of PVDF and we'll shuffle our feet on the carpet to keep our cell phones juiced up.

Motion to levitra without prescription online Energy Power Raises $8M

What if your everyday activity of walking could be used to provide your iPod's battery the hours of life it needs to play tunes? That's the idea behind a new startup working on solutions for mobile and large-scale power generation. The company is called M2E Power and it just announced investors have put some $8 million behind its idea.

M2E (Motion to Energy) says its system of http://www.tenasys.com/viagra-10-mg power generation works by means of a "micro-generator combined with traditional battery storage to create a system that captures the kinetic energy of normal everyday motion – human or vehicle – to generate electricity sufficient to power mobile devices." M2E sees that with a normal amount of daily movement many products will either need no recharging at all or will have a longer run time before needing to charge. The company sees its technology also being used in larger-scale generation situations like wind or ocean wave power.

The M2E idea apparently came from Department of Energy-funded research in Idaho. The inventor, Eric Yarger, worked with a team in developing the technology initially for military uses. It uses the Faraday Principle (energy produced via motion of a magnet through a wire coil), according to Yarger, but with select changes in place to www.intherooms.com provide for broad usage. The technology is still focused on military development right now but will probably find its way to consumer applications shortly.
