Magnetic RAM is Faster, Uses 90% Less Power

IBM and Toshiba are looking toward the next generation of RAM. They want it to be faster, of course, but they're also hoping to score two of the biggest unobtained prizes in RAM:

  1. Instant Boot
  2. Unpowered Storage

Instant boots save energy in several indirect ways. It promotes powering down computers at night, as the powering up becomes less inconvenient. Unpowered storage decreases power use dramatically because the RAM can continue to hold data without having to constantly pull from the power supply. Toshiba estimates that the MRAM will use about 10% less energy per megabyte than today's RAM.

Unfortunately, MRAM currently has problems operating at a wide variety of temperatures. The inside of a computer has a pretty wide temperature range. Toshiba says that they have overcome this problem, and they expect MRAM to take over the market by 2015.

Dell Takes Lead in Green Technology


Yesterday marked the one-year anniversary of Dell’s commitment to be the greenest technology company on the planet. We've talked before about all the efforts Dell is making to greenify their operations, products, and image, so it's time to take a look at how far they've come. Along with innovative products, they have some significant landmarks to celebrate from the past year.

First, they reported their largest single-year product recycling volume, recovering a massive 102 million pounds of IT equipment from customers – a 20% increase from the previous year. The fact that they've made recycling IT products easier for consumer has helped thes number grow so dramatically.

A second accomplishment to celebrate is their becoming the first major computer manufacturer to offer Silver 80 PLUS-certified power supplies. The 80 PLUS certification means that the equipment exceeds the power supply requirements specified by the EPA’s Energy Star 4.0 standard, which requires the use of 80% or more efficient power supplies. Dell passesd up the standard by 8%, and is a year ahead of schedule for meeting the qualifications of the Climate Savers Computing Initiative. This is nothing new for Dell – since 2005, improvements to their desktops alone have avoided creating about 24 million tons of CO2. Their newest desktop, the Vostro Energy-Smart 410, can save users up to 47% in annual energy costs without loosing performance.

And a third item for celebration is progress in Dell's global zero-carbon initiative. Partnering with The Climate Group’s Together initiative, which brings companies, cities, and non-profits together to reduce American’s impact on the planet, Dell is working to provide resources for consumers to manage and reduce energy consumption, in addition to Energy Smart and Plant a Tree for Me. Back in September, they decided the company operations should be carbon neutral by the end of ’08, and they’re on track with that goal, already powering corporate headquarters with 100% green energy and showing themselves to have the lowest carbon intensity of the Fortune 50.

While we know there is more than simple do-good motivation behind the progress, it is nonetheless encouraging to see such a major technology company taking significant steps to clean up their company. It is sure to pull competitors into following their trail, especially since consumers increasingly want products that are both cheap and green, and higher efficiency now means cheaper products later.

 

Your Old Computer Deserves Your Love

Have you got a few minutes? I thought so...well, I suggest you spend them watching the above video. Not only is it semi-adorable, it's got a moral we can really get behind. "Love the one you're with," particularly, the computer you're with.

It takes more energy to create a computer than the computer will consume in 10 years. I know that we're geeks, and that the new machines are always oh-so compelling, but there's something to be said for upgrading. You might find that a little bit of simple maintenence might restore some of your 1.5 ghz machine's former glory. The simplest upgrades, RAM, hard drive and (for laptops) a new battery, certainly won't run you more than a hundred dollars or so.

But the most necessary bit of maintenence (that this video won't tell you about) is an occasional re-install of the operating system. It's essential to wipe your machine of all the memory-consuming crap that youve acquired over the years. And a re-install won't cost you a dime...but it will take some time. The question is, is your old computer worth it? Do you love it enough to give it the gift of life?

Maybe these statistics from lovethe1yourewith.com will help you make up your mind:

  • The energy required to produce a new computer is enough to run a computer for 10 years
  • The energy saved by extending the life of your computer by a year could run it for 2 years
  • 220 million tons of e-Waste are generated annually in the USA
 

Compression Could Reduce Data Center Energy Use by 95%

Data center and sexy don't seem to quite work in the same sentence. But greener data centers? Ooh, we've got chills now.

U.S. business servers and data centers suck up the energy equivalent of all the electricity consumed by color televisions. The industry uses about the same amount of electricity as 5.8 million average American households. How to green such a massive sector? Start with better data compression technologies, which is already widely used in backup and secondary storage to decrease the capacity needed for these functions.

Broaden out that concept and apply compression to primary data, such as application servers, email or databases and that will radically reduce data center energy usage. Storwize Inc., a San Jose, CA tech company, has a process to reduce data center energy usage up to 95 per cent.  This means on a 100 TB database, Storwize can compress that to less than 10 TB of physical disk.

Real-time data compression reduces the amount of data written to storage devices and thus reduces CPU, disk, memory and network utlilization on the storage system. It can do this through its patent-pending algorithms that allow write and read operations from any location within the file while avoiding the need to decompress the whole file.

Compressed data doesn't just save energy use, it reduces the real estate required to house the data centres, the energy needed to cool down the space and all the other trappings of physical space that adds up to a heavier footprint on the environment. 

 

High Schoolers Reduce 2-Stroke Emissions by 40%!


This is the third in our series of projects from ISEF that we will be covering. Many more to come. Thanks to Intel for flying me out and putting me up so I could cover the conference.

Denmark may not be a big country, with only 5.6 million inhabitants, but there are more than 160,000 mopeds there, not to mention lawnmowers, chainsaws, and even cargo ships that transport goods. Each of these have a common thread: they all run on two-stroke engines. Michael Madsen and Jesper Rasmussen, both riders of mopeds, found out one day how utterly inefficient and polluting they could be, even for their size. The reason is that with two-stroke engines, no matter the size, when fuel is injected into the cylinder, part of it is allowed to escape through the exaust manifold (see white spheres in picture).

This means that not only are you sending a large portion of your fuel in the exhaust without burning it (30-40% on average in chainsaws), these hydrocarbons are released into the atmosphere as reactive organic gases, which cause a slew of health problems. Madsen and Rasmussen decided to design a system that would eliminate these problems and make the engine more efficient. What they’ve done is created a unique design in their exhaust system that pushes the overflowing hydrocarbons, along with a little of the exhaust, back into the cylinder by way of a shockwave traveling at 500m/s.

This allows the fuel to be completely burned, and has resulted in a fuel efficiency improvement of 17.7%, just for their mopeds. Carbon monoxide has been decreased by 10% and hydrocarbon emissions have been reduced by 36.7%. The system is even more efficient in hot, dry climates, so would work well in areas like California, many countries in Asia, and the middle east. Heavy cargo ships, carrying some of the most polluting engines in the world, would greatly benefit from this technology, and the team has patented their system and hopes to bring this to market in the future.

Frankly, it makes us at EcoGeek feel like we're slacking. If this is what high school students are doing, shouldn't we be doing a bit more than just blogging?
