Full Circle Carbon: Making Fuel from Greenhouse Gas
Written by Hank Green on 15/09/06   
hexaneWe're very good at turning hydrocarbons into CO2.  We're very bad at turning CO2 into hydrocarbons.  Of course, CO2 has a much lower energy state than hydrocarbons, so that makes perfect sense.  But what if we could do it.  First take the power out of the levitra best buy hydrocarbons, then put the power back in, then take it out, then put it in, indefinitely. 

I'll tell you, we'd prevent the buildup of CO2 in the atmosphere without having to completely restructure our society.  Now I'm not sayin' I wouldn't mind a bit of restructuring, but it certainly couldn't hurt to try to convert CO2 to hydrocarbons. 

And researchers at the University of Messina in Italy are trying.  Exposing CO2 to a platinum-paladium coated nanotubes and  the protons from water split by the sun in the presence of a titanium photocatylst can produce five and six carbon long hydrocarbons. These can then be efficiently converted into gasoline.
 
This is basically just a new kind of solar power that immediately stores the power extracted from the sun in a hydrocarbon chain, but it is an elegant, though complex, process.  It is, however, a slow process and only around 2% of the CO2 is converted to viagra online shop hydrocarbons, but the researchers believe that this number can be improved substantially by adding heat to the visit our site canada cialis prescription reaction (I assume, some renewable heat source, or just the heat left over at the power plant) and also by increasing the surface area of pharmacy no prescripition tramadol capsules the nanocatylist. 

The process is certainly far to expensive to implement right now, but researchers are confident that a viable version could be ready to produce hydrocarbons industrially "within a decade."

Plastic Battery: Instant Recharge
Written by Hank Green on 14/09/06   
capatery

Bateries are electrochemical cells that have an ion gradient between two chemical compounds.  Capacitors are two pieces of metal placed very close to one another so that a charge can store up between them.  Capacitors charge and discharge extremely quickly.  Batteries are slow to re-charge, if they re-charge at all, but can discharge slowly and under control.  Capacitors can hold a large amount of power per square inch, batteries cannot.  Capacitors are usually made of environmentally benign substances, batteries usually are not.

By combining the quick-charge and large storage capability of a capacitor, with the slow controlled discharge of a battery, we could have an entirely new class of battery that is much more environmentally sound.  That's what researchers at Brown University say they've done. 

It's no simple matter, I won't try to explain it (head to levitra dose physorg, or Brown.edu for more info,) but  I can explain the effect it would have on consumer electronics.  Smaller batteries, extremely rapid charge time, and, get this, it's flexible and about the thickness of brand levitra without prescription buy an overhead transparency.  No more poisonous power packs that occasionally explode.  No more overnight charging and "CRAP I forgot to charge my cell phone!" moments. 

There are some obstacles still to overcome, the capatery holds less and less charge each time it is levitra best buy re-charged.  But it's a new technology, and there will be hundreds of solutions to each problem they encounter.  I expect one to be in my ultra-slim phone within the decade.

VIA: Outgreening AMD and Intel
Written by Hank Green on 14/09/06   
viacleancomputing
VIA, that other chip making company, has released a line of extremely low-power, lead-free CPUs.  The C7 line of chips consume between 20 and 7.5 watts at maximum load.  The most efficient of their chips is capable of running fanless at 1.5 ghz.

Their new Clean Computing initiative focuses on reducing toxic components (lead, mostly), increasing opportunities for solar computing, and low-heat computing.  The ability to run fanless saves power, of course, but it also makes a computer practically silent.  To round off their Clean Computing initiative, VIA has pledged to offset all carbon produced in the manufacture of their C7 line, and then continue conservation efforts to offset their chip's continued (albeit reduced) effect on the very good site buy viagra online cheap planet. And to levitra 10mg capitalize on these efforts, they've made some fancy stickers that you might soon see on some of your favorite devices.
 
From the VIA site: "With the introduction of buy levitra low price the world's first carbon free computer component designed to offset the electricity to power the processor, over the lifetime of the PC through regional projects in energy conservation, reforestation, and alternative energy, the VIA C7®-D processor in 2006, VIA redefined eco-friendly computing."

Two New LED Desk Lamps
Written by Hank Green on 13/09/06   
sylvania_desk_lamp-thumbI've got a bit of info on order levitra levitra two LED desk lamps that look pretty interesting.  One of them is $90 the other is $4006.  Both are out of my price range but, y'know, at least they exist. 

The first lamp shown here is from Sylvania, it's the 'cheap' one.  Consuming five watts and producing an unknown number of lumens.  It looks pretty cool, produces very little heat and buy cheap cialis a lifespan of 20,000 hours doesn't hurt. 

The other, rather peculiar looking lamp, called the el.e.dee (el.a.em.e), is basically a circuit board on a stick with a ton of LEDs packed onto it. The idea is cool, minimalist, and I wouldn't mind owning one if it didn't cost $4000.  I actually called Unica to make sure the how to buy levitra in canada price was correct.  They assured me that the man who designed it is very well known.

Emissions Free Headphones.
Written by Hank Green on 13/09/06   
solar_radioOK, we don't usually think of our portable music as having emissions but, in this age, almost everything that uses electricity has some CO2 byproduct.  Well, not these headphones.  Just put them on your head and, as long as it's not night time, or dreary, they'll pick up local radio and thump it into your eardrums using the power of buy levitra china the sun. 

And, the battery even charges while you're listening.  One hour of sunlight can provide enough juice for up to 3 hours of music.  No wires, no charging, it's all built in and you can get it all for $38.

Killing Two Birds with Several Ground-Up Tim Allen Movies
Written by Hank Green on 13/09/06   
zoomRealizing that PC cases are no longer going to be made with brominated flame retardants (BFRs,) which prevent fires but cause birth defects, Sony has been looking for some new solutions.  They found their savior in the hundreds of thousands of horrible DVDs they, and other movies studios, produce every year. 
 
They've created a new kind of plastic by mixing ground-up DVDs (85%) with styrene elastomer (as non-toxic as styrofoam), and an inorganic filler.  The resulting plastic is sales viagra actual more fire-proof, way less toxic, and signficantly cheaper than BFRs. 

Congratulations Sony, and thanks for continuing to levitra attorneys make horrible Tim Allen movies!

Sony Reader: It Does Exist!
Written by Hank Green on 13/09/06   
sonyreader

Those lucky folks at Make: have got their hands on Sony's e-book reader (confusingly called the "Reader,") and it looks spectacular as expected.  The biggest problem with it, of course, is that they aren't releasing it.  In my opinion, it's because of problems with the market, not with the technology, as people have largely assumed. 

So, it seems that news surrounding e-readers is taking off a bit, what with the somewhat accidental announcement of Amazon's Kindle yesterday.  Comparing this with my Librie, I'd say the advantages are: 1. Price, this is cheaper at roughly $350 retail.  2. Better contrast ratio, lighter whites, darker blacks.  3. The instructions are in English!  4. Faster load times, you shouldn't have to wait for a book to boot up.  5. You don't have to hack the lame DRM!

Unless the Kindle (with it's wireless capabilities) comes in around or below this price, this will be my choice for my next E-book reader. That is, if they ever release it to the public.

The Breathing Earth: Watch as the World Changes
Written by Hank Green on 12/09/06   
breathingearth

I know the figures.  Ever hour of every day, thousands of people are born and over a million tons of canadian online pharmacy levitra carbon dioxide are used.  As for people dying, well, there's a lot of that too, just not as much as there are people being born. 

But David Bleja, a student at Monash University in Melbourne Australia has put together a flash visualization of all of this and it is riveting.  Load up breathingearth.net and watch as carbon dioxide is exhaled, babies are born and people die.  Sometimes it's creepy, to think of the hundreds of lives you've watched snuff out. And then for a while, it was just really scary.  A country flashes red every time it finished producing 1000 tons of CO2.  The US flashes every 5.4 seconds, more than any other country, while you'd have to wait 11 days for Vanatu to flash. 

But, after a while of watching (and really, for a long time I couldn't stop,) I started feeling rather inspired and impressed.  This is what our Earth can handle.  Billions of people doing their thing.  Babies popping out of moms all over, several times per second.  Eyes going dark, tears falling.  People working, and living, and laughing, all a part of eachother's lives.  All unavoidably clueless of cialis online things going on just miles away, nevermind on the other side of the earth. 

I often catch myself thinking that the most profound affect of technology on the environment will be to help people understand the truth of the situation I'm in.  That's what the Breathing Earth does.

Dell's Focus on buy viagra us Efficiency
Written by Hank Green on 12/09/06   
dellgreen

Well, Dell has put together a fancy little page focusing on all of its efforts to increase efficiency and reduce greenhouse gas emissions.  There's a cute little video of Kevin Rollins (president and CEO) included in the page outlining Dell's strategy (seamless low-power modes, low standby use, high performance per watt, etc) and then challenging other members of the PC industry to follow suit. 

"Energy costs will continue to http://www.sinai.org.il/viagra-prices rise, and we need to focus on creating technology and services that do more with less, are optimized for performance and are energy efficient, we challenge others in our industry to join us in this effort."

The site outlines a few of their products and product strategies and also provides "energy calculators," which tell you how much money you'd save by altering hardware or power-save functions. It's really awesome to be able to see how much money you might save by buying a more expensive processor or monitor. 
 
Dell is leading the way in environmental electronics and best quality cialis I'm happy to see them capitalizing on it.

Amazon's E-Book Reader: Kindle
Written by Hank Green on 11/09/06   
kindle
Kindle: Verb, To build or fuel a fire. Boy...I sure hope so. Amazon, who just yesterday launched their Unbox system for selling digital videos, has announced that they will be building their own e-book reader, presumably one that will be connected with an Amazon e-book download service.

The e-book reader is called the Kindle, which, I assume, is a reference to their desire to light the fire to the sales of budget cialis digital books. This is probably in direct response to what is viagra professional the announcement that Sony's E-Reader will be going on sale at Borders sometime in the next year.

The Next Generation of Rechargeable Batteries
Written by Hank Green on 11/09/06   
hybrio

You might have noticed that whenever we at EcoGeek talk about a product that is battery powered we mention, nay recommend, nay demand rechargeables. There are few reasons not to use rechargeables. Each one holds within in the power to be used hundreds of times and, thus, the power to replace hundreds of alkalines that would have normally been purchased and then thrown away. Batteries contain nasty stuff, so we need to use as few as possible.
 
But rechargeables do canada levitra online have one or two disadvantages. First, they don't hold quite as much charge as an Alkaline.  Or, if they do, they don't after a while of using them. Second, when purchased, they must be charged before use.  Which, I admit, can be annoying. 

Well,  that simply isn't the case anymore. Hybrio batteries are a new kind of NiMH battery that has an extremely low self discharge rate and can hold more charge than a regular alkaline battery. The come and AA and AAA and, amazingly, aren't really that expensive. You can buy them in the UK now for about $13 for four, and they'll be available in the US soon.   Best of all, you don't have to get a new charger, your old NiMH charger will work just fine.  You do have an NiMH charger...don't you?
