Carbon Footprint of E-Readers Higher Than Print

Digital delivery of content for e-readers is a rapidly expanding market. Many assume that, because trees aren't being cut down and used to maufacture paper for books, e-readers (including the Kindle, Nook, iPad, and the like) are a greener way to read books and magazines. But a broader look at the use of where to but viagra safe these devices that includes the life-cycle of the e-readers themselves paints a much bleaker picture about how green they really are.

The article first looks at the carbon emissions for an average adult reader who reads 6.5 books per year. Paperback books have a footprint of 26 kilograms (over 57 pounds) of CO2, as compared to just under 70 grams (about 0.15 pounds) for the e-reader. But the tables are turned drastically when the best prices on brand levitra carbon footprint of the reader is added in. The carbon footprint for this average reader is almost identical (130 kilograms or 285 pounds) when expanded over 5 years.

But how many people still use 5-year old electronic devices? Assuming a 2-year replacement cycle, the chart shows that the iPad carbon footprint outstrips that for the print reader, and even the more efficient iPad2 has more than double the emissions over a 5 year period. High-volume readers and those who hold on to their electronic devices for longer periods may make the e-reader a more suitable choice, but technological alternatives aren't always all their proponents would like consumers to believe.

Free Modlet Offer for NYC Residents to Save Air Conditioner Power This Summer

CoolNYC is a cooperative program being offered by Con Edison and ThinkEco which will provide up to 10,000 free thermostats and Modlet plug-in electrical outlet controllers to New York City residents to be used to monitor and control window air conditioning units. The hope is that controlling window AC units can help reduce peak electrical demand this summer.

You may recall the Modlet, which we noted late in 2010 when it was a Top 10 Green Building Product. The Modlet is a smart outlet that plugs in to a conventional outlet and find discount viagra online allows you to control and monitor energy usage wirelessly. With the Modlet, appliance use can be scheduled for particular times. There are also apps to allow iPhone and Android devices to control Modlet outlets remotely.

The Modlet networks to a computer via a wireless USB dongle, but it has built in memory so it can run for up to two weeks without connecting to the visit web site cheap cialis 50mg computer. If there are several Modlets in the home or office, they will conect to each other with a mesh network, so not every one has to be in range of the computer in order to work.

For those outside New York or who don't qualify for this program, the Modlet retails for about $50.

An "Unprinter" to Clean Laser Printed Paper

Scientists at the University of Cambridge (England) have developed a method using lasers to remove the toner from a laser printed page, which would allow the paper to be reused. With the "unprinter," a green laser is flashed at the page. This does not harm the paper, but the light is absorbed by the toner, causing it to detach from the look here viagra on line paper.

Because of the difference in technology between laser printing, where the toner sits on top of the paper and is fused to it by heat, and inkjet printing, where some of brand name cialis the dye is absorbed by the paper, it probably would not work (or would work less well) with inkjet printing.

As noted on Slashdot, "Recycling paper is a good step in the right direction, but it still pales in comparison to unprinting. In a worst-case scenario, The University of Cambridge unprinting method has half the carbon emissions of recycling; best-case, unprinting is almost 20 times as efficient."

Raspberry Pi is a Low-Power, Credit-Card Sized Computer

A low-cost, low-power, credit-card sized computer developed by a charitable foundation set up by some computer science instructors from Cambridge University. Their goal was to produce a very inexpensive, low-power computer that could be used by kids to learn programming. Now the first examples of the resulting low-cost credit-card sized computer are about to reach the market with a starting price as little as $25.

"The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard. It’s a capable little PC which can be used for many of the things that your desktop PC does, like spreadsheets, word-processing and games. It also plays high-definition video. We want to see it being used by kids all over the world to buy cialis tablet learn programming."

The Raspberry Pi is an ARM-based, SoC (system on a chip) computer that is just slightly too large to fit in an Altoids tin.  It will run several varieties of Linux operating system. Fedora Linux is levitra without perscription its recommended distribution, and it will also support Debian and ArchLinux (some issues with Ubuntu and the ARM processor prevent Ubuntu from supporting it at this time).

The Raspberry Pi is capable of delivering BluRay quality display. The developers say that "graphics capabilities are roughly equivalent to Xbox 1 level of performance. Overall real world performance is something like a 300MHz Pentium 2, only with much, much swankier graphics." It has ports for composite and cheapest cialis uk DVI (using a cheap adapter for the DVI) video output.

Power to run the Raspberry Pi can come from a phone charger or even from 4 AA batteries. A 700 mA USB charger will be the prices generic cialis power source for the Model B, and the Model A can get away with even lower power requirements (300 mA). At that low power level, solar powered options should be practical and not terribly expensive.

The Raspberry Pi comes in two models (A and B) with 128 MB and 256 MB of RAM and priced at $25 and $35 respectively. Lots more information and specifications are available in the Raspberry Pi FAQ. The Raspberry Pi will be available beginning at the end of get cialis cheap February 2012.

Sprint Will Require Green Phones

Cell phones are a big source of e-waste, accounting for millions of phones that are discarded annually. Some steps have been taken to try to make some cell phones greener, but it's been small measures so far. However, wireless network provider Sprint is now planning to require all of the cell phones for the network to have green certification.

The standard for mobile phones, developed by UL Environment along with cell phone manufacturers and other industry members, is known as UL ISR 110 (PDF). It is a third-party testing standard that evaluates phones in the categories of Materials Use, Energy Use, Health and Environment, End of Life Management, Packaging, Manufacturing and Operations, and Innovation.

The Samsung Replenish is the first handset to achieve certification under this standard. The Replenish is largely recyclable, as well as having recycled content for many of its components. Sprint hopes to have 70 percent of its handsets meet the certification by the ned of next year.
