Anything that removes a wire or frees up an outlet has a place in my office.  My battery charge has a permanent place hanging from my wall charging double and triple A's that power my wireless mouse, my Sony Librie, my digital camera, various remote controls, etc.  But the Everfast USB charger promises to rid my ofice of those wires and free that battery outlet.  Unfortunately, my USB outlets are not in extreme abundance either.  But it would be nice to be able to charge my batteries right here where I sit, and not have to get up and walk all the way across the room to replace my mouse batteries. 

The chargers accept two batteries at a time, either AA or AAA and charge nickel metal hydride batteries (always make sure you're using the right battery with the right charger.) 

So, if you want to reduce your heavy metal waste without taking up extra outlets, or if you're too lazy to leave your workstation to get a fresh pair of AAA's you might want to look into this.

PopSci: 10 Steps to End our Fossil Fuel Addiction
Written by Hank Green   
Sunday, 18 June 2006
Popular Science is currently featuring the "10 steps to end America's fossil fuel addiction. "  Their steps make a lot of sense to me and they even quote Amory Lovins, sustainability guru, in their tenth step. 

So, here are the steps, the details are definitely worth a read:

1 Harness the Wind
2 Make Power where we use Power
3 More Hybrids
4 Better Ethanol
5 More Solar
6 Use Hydrogen
7 Wave Power
8 Geothermal
9 Make gas from Trash
10 Use less energy

All together, an excellent article.  Nothing in it is controversial or new, but it's exciting to see something so EcoGeek featured so prominently.
 
Possibly the most interesting thing about the article, though, is the excellent graphic by Nick Kaloterakis that shows a gas pump twisted into a light bulb.   Upon inspection, howver, it's quite obvious that this 3D model was originally a gas pump twisted into a noose, and it's just been very slightly reworked to look like a light bulb. 

I don't actually have permission to use these images, of course, please don't sue me.

Green Smart Phone
Yes, this is the phone...in it's cradle.
And speaking of cell phones...isn't this a beauty!  Of course, it's just a concept, but we couldn't help but share.  This little phone, about the size of a credit card, was created to be an Eco-Phone.  Made out of bamboo, lower power E-Ink display, etc. 
 
The concept further pleases the EcoGeek by providing a rewards system for green activities.  Designer Nicola Reed says that a phone such as this could be able to analyze the user's day to day impacts on the environment.   Based on that analysis, green users are rewarded with free minutes and other bonuses.
 
We don't know that Verizon would buy intosuch a scheme, but Nicola gets props for the idea nonetheless.
 
 
 
A New Kind of Solar Cell

 Solar Cell Phone
 
We've already seen prototypes for a solar powered MP3 player here at EcoGeek, and a solar cell phone is an obvious next step for the prototypers of the world.
 
Fraunhofer-Gesellschaft is a consortion of over 50 technology research firms (most of which are, surprise! German.)  Details on their solar powered cell phone are sketchy, and we are skeptical. This would, at best, simply be an alternate method for charging your phone.  It wouldn't replace power chords and, unless solar panels get much more efficient (or some mysterious Russian substance saves the day) there simply won't be enough surface area on a phone to power it.
 
Now, we should be fair, phones are getting more efficient all the time.  But they're also getting smaller (less room for panels.)  I'm ready to say that, if this ever happens, it's five years away.  For now, we'll just have to settle for solar backpacks and clothes .
 
 
 
Solar Powered Backpack

Voltaic Backpack
The Orange style Backpack
Whether you're a bustling urbanite or a happy camper (or both) your portable devices need to be charged. The New York City based company Voltaic provides the solution in the form of bags that double as mobile power generators. Three solar panels grace the bags and generate up to 4 watts of power, allowing you to recharge most small electronic devices including: cell phones, cameras, two way radios, PDA's, and MP3s. Unfortunately the bags won't charge your laptop.
 
The award winning bags come with eleven standard adaptors for common cell phones and other devices and a full range of optional adaptors are available on the website. Best of all, is the battery pack containing a 2,200mAh Lithium Ion battery, a voltage converter, built in LED torch and charge indicator. It clips inside the back pocket of the bag and allows you to save the juice for later. In case the forecast is really gray, the battery pack can also be charged using an AC travel charger or car charger (both included).
 
Currently Voltaic offers 4 different models, Backpack, Daypack, Pouch and Messenger and you can customize your bag by choosing the color of the solar panels – silver, orange, green or charcoal.  Regardless of which you choose, curious random strangers will stop you and ask "are those solar panels?" giving you an excellent opportunity to speak to the virtues of renewable energy sources.

Memory Sticks 
 
The quirky Dutch design studio OOOMS has created a USB 2.0 flash stick housed inside of an...actual stick. While the odd juxtaposition between the computer and the natural stick is a nice way to declare to the world that you are an EcoGeek, there is nothing really environmentally friendly about the product.

Each stick is hand picked from the forest. Selected based on natural beauty, no two are alike. Choose from four sizes, 128Mb, 256Mb, 512Mb or 1Gb available at OOOMS website . While you're there check out other clever designs like Rebellious Cabinets, Hairhats and the Anti Gravity Machine.

 

 
I am Stuck on Fuel Cells

bandaid fuel cellMake: makes our hearts warm.  And Make: writer Gavin Harper can make a fuel cell out of a couple of bandaids .  So, listen up, all you need is two bandaids (the kind you would put on a nice big knee scrape,) some steel screen (the kind you would put around your pool in Florida,) some methanol (which, alas, you probably shouldn't have lying around the house) and an MEA (Membrane Electrode Assembly, which you should probably buy, rather than Make.)
 
Follow the simple instructions and, voila, a fuel cell.  Just plop a couple drops of methanol on your creation and, voila, .25 volts.  Enough to power, well, not much.  But still, your very own fuel cell.
 
 
 
The H Train
Written by Hank Green   
Tuesday, 13 June 2006
Some countries actually use mass transit.  Especially countries where urban centers are as densely packed as they are in Japan.  East Japan Railway Company servers some 16 million passengers every day.  When your citizens use mass transit, it becomes important to make that
JR East's Fuel Cell Train
JR East's one-car fuel cell train prototype
transit efficient and non-polluting.  JR East is working on alternative fuels for it's train system.  We've already mentioned their hybrid train technology, but now they're taking another step with a plan to introduce a fuel cell powered train. 

Right now they're still in the planning stages, of course.  The first trial would have a one-car train pushing 65 mph and emitting only water as its waste.  The train will also be 'hybrid' in that electric batteries will also power the train and charge when the train breaks.
 
The biggest obstacle to the introduction of hydrogen vehicles has always been lack of infrastructure.  How many gas stations have you seen with hydrogen pumps?  This is less of an obstacle for trains, because there are fewer fueling stations and the fuel cell trains will follow specific lines, but creating the infrastructure will still be a challenge.
 
Biodiesel Circumnavigation: The Power of Pete's Ass
Written by Hank Green   
Saturday, 10 June 2006

Circumnavigating the globe in a biodiesel powered, ultra-efficient trimaran is one thing. Adding one liter of biodiesel extracted from your own ass is something else.

Image
Yes, that's pete having his biodiesel removed.
Pete Bethune is circumnavigating the globe for two reasons. First, to beat the speed record for circumnavigation. That will take about 65 days, besting the current record by ten days. Then Pete and his team will tour around the world for 18 months to raise awareness for renewable resource use.

And, yes, Pete had a pound of fat removed from his butt to be mixed with the fuel of his craft. A sacrifice, I suppose, he was willing to make.

How Many Miles per Gallon Does Your CPU Get?
Written by Hank Green   
Saturday, 10 June 2006

We might all be plenty happy to ogle over the next gigahertz revolution, but CNet recently pointed out that rating processor performance alone is becoming a useless measure. We can make the processors fast, the quesiton is, can we do it without burning through the mother board (and the electric bill).

Unfortunately, the MPG of a CPU (theoretically measured in performance per watt) is not a simple thing to calculate. The measure of hertz, meaning processes per second, is now pretty much ignored. There's no perfect way to measure the performance of a CPU, and there is really no way at all to accurately measure performance per watt.

ImageSure, you could hold a thermometer to your CPU and run a billion calculations and divide one by the other, but AMD and Intel are going to start advertising these numbers, so they're going to have to figure out some industry standards.

Unfortunately the performance per watt of a processor tends to vary significantly as the processor is used more or less. Intel is measuring it's processors at full load, something very rarely seen by a processor, with encouraging results. AMD, on the other hand, says a more natural system for measuring performance should be tried.

Already the battle has begun, Intel claiming that its new server processor, Woodcrest, has overtaken AMD in terms of performance per watt, but AMD disagrees.

All of this, if you can believe it, is a big deal for IT industry power consumption. Fifteen percent of money spent in the operation of data centers goes to power and cooling down all of the hotness the processors create. And the fight over performance per watt is a good one for the industry, the customers and the environment.

Let's just hope they can agree on how to measure it.

Note: Since this article got Dugg there's been a bit of discussion about the lack of real, hearty, technical information here.  Let me just say that I wrote this mostly as a redirect to the CNet article, which does have a lot of great information on it, and that I didn't expect this to get on Digg.  It was nice surprise though.  Thanks to everyone who's visiting EcoGeek for the first time, and check out the CNet article if you want more details.

 

 
Build Your Own 1000 Watt Wind Turbine
Written by Hank Green   
Saturday, 10 June 2006

Homemade Wind TurbineLive in a windy place? Need an extra 1000 watts? It's certainly enough to power your laptop, and probably also a microwave oven at the same time. What else could a guy want?

The folks at instructables are creating a step by step guide to creating your own 1000 watt wind turbine – from scratch. Sadly, the tutorial isn't finished yet, so, if you start now, you might be spending a lot of time staring at your wire coil disk waiting for them to write the chapter on creating the turbine blades. Nonetheless, the complex stuff (DIY power generator) is all finished, so it's worth a look.

 
Mysterious Russian 'Star Battery': Explained (almost)
Written by Hank Green   
Thursday, 08 June 2006
ImageWell, we've been keeping our eyes open for more information on this 'stellar battery' that we blogged about last week. Twice as efficient as a solar panel, operates in darkness and low light, cheaper than a solar panel. Lacking details, we were skeptical.

Well, the Russian scientists at the Joint Institute for Nuclear Research (JINR) have given us some more information. They're claiming a 54% efficiency in converting visual light to electricity. They're claiming a system of storing that energy that does not use acid batteries, and they're claiming a 31% efficiency at converting low-light and infrared light to electricity. And, finally, they've actually given us a glimpse of how, exactly, this is supposed to work. Of course, they told the world in Russian, and we don't speak Russian, but we're happy to try and translate the translation / explaination we found at PESN.

Summary:
The Russians said:
We have a revolutionary new 'star battery' that is made of heteroelectric matter.

The Russians meant to say: We made an ultra-capacitor and an ultra-efficient photoelement out of a metamaterial.

Now, this might not strike you as a huge difference. But we can actually figure out what they're talking about in the second sentence, while, if you google “heteroelectric” you find only articles talking about the star battery.

Global Climate Change Model ScreenshotOnly the most foolhardy among us continue to be in denial about Global Warming. Experts agree - it's happening. Problem is, nailing the specifics is tricky. The vast number of variables involved makes for complex models requiring processing power that makes Deep Blue look like a sissy.

The BBC Climate Change Experiment hopes to predict the future climate of our planet by harnessing the power of distributed computing (remember SETI@Home). You can join in by downloading a small program that will connect your computer to the experiment. The application doubles as a screensaver, and uses your computer's excess processing power to crunch away at the Met Office climate model .

An open source platform for distributed computing called Berkeley Open Infrastructure for Network Computing (BOINC) is being used to run the experiment. Developed specifically for individuals to donate their computing power to scientific projects, BOINC harnesses processing power that would otherwise be wasted. The more people who participate in the experiment, the more complete predictions about the future climate will be.
