The Voltaic Solar Charger Messenger Bag (1004-S) is reinforced and padded to carry and protect a laptop. This portable solar charger has large zipped pockets for documents, and multiple small pockets for electronic devices. Ideal for use in town or as a travel bag.
Embedded in the outside of these solar chargers are lightweight, tough, waterproof solar panels. This Voltaic Solar Charger Messenger Bag produces 4 watts of solar power; 1 hour in direct sun will power over 3 hours of iPod play time, or 1.5 hours of cell phone talk time.
All Voltaic solar charger bags come with a custom battery pack which stores any surplus power generated, so it is available when you need it - not just when the sun is up. The battery packs can also be charged using the included USB charger, making them just as useful on the grid as off.
All bags include standard adapters for common cell phones and other hand-held devices. Even without an adapter, you can charge most devices with the included standard car charger or USB charger.
Voltaic solar bags use fabrics made from recycled PET (i.e. soda bottles). Voltaic worked extensively with suppliers to develop these fabrics, since they were not previously available. Recycled PET fabric is light weight, extremely durable, UV resistant and water resistant. It even looks better than the nylon it replaced. Most importantly, it uses significantly less energy to produce and creates demand for recycled materials.

Unions & Big Solar Square Off in California
By Dan Harding | September 15, 2009
Organized labor is pressing hard to both accelerate and gain a strong foothold in the renewable energy industry. This simultaneous push for green jobs and a green economy has garnered plenty of friends for unions, from environmental groups to consumer advocacy groups to many in the solar industry.
In California, however, this “blue-green alliance” is being strained as Big Solar firms push to get proposed solar plants underway and Unions push for a larger stake in the building and implementation of these plants. On the union side you have California Unions for Reliable Energy (CURE), a consortium of Union leaders working together to increase organized labor’s stake in California’s energy infrastructure, renewable plant or not. At the same time large solar firms, such as Ausra and BrightSource Energy, are pushing hard to get streamlined approval for their solar power plants, often with support from legislators and utilities, themselves trying to implement or achieve state renewable energy standards. In some cases, most notably with Ausra, CURE has thrown a wrench in those plans by delaying a project due, ironically, to environmental concerns.
Why would the unions look to undermine these large solar power arrays?
Ostensibly because Ausra, among others, refused to sign a project labor agreement. Contrarily, when BrightSource Energy, which pledged to hire union contractors, moved to get their desert solar project underway, CURE made no objection whatsoever, despite some local opposition by environmental groups to such power plants. This apparent double standard is enraging many on the business end of the issue. They claim that unions are muscling in on their jobs, essentially blackmailing them into accepting union labor; something Kevin Dayton of the Associated Builders and Contractors of California called “greenmail.” CURE leaders counter that they are able to work with companies such as BrightSource from within on job site environmental issues, whereas they must use all means available with non-union companies like Ausra. Those means have primarily entailed last minute, and very extensive, environmental “data requests” — a significant nuisance for solar companies in a rush. Carl Zichella, the Sierra Club’s
director of western renewable programs, said California Unions for Reliable Energy had been effective at extracting concessions that aid the environment.
In the end, there is a lot of finger pointing going on — Unions want high-paying solar and renewable energy jobs now, Big Solar does not want to pay the higher labor costs. This fight in California is important because it may set a precedent for such fights around the country as renewable energy becomes more widespread. California is the front lines of a battle between Union and Business that will spell out the future of the green-collar economy.

Thin-layer Solar Cells May Bring Cheaper Green Power
ScienceDaily (2007-08-24) -- Scientists are researching new ways of harnessing the sun's rays which could eventually make it cheaper for people to use solar energy to power their homes. The experts at Durham University are developing light-absorbing materials for use in the production of thin-layer solar photovoltaic (PV) cells which are used to convert light energy into electricity.
Nanotech Batteries For A New Energy Future
ScienceDaily (2009-03-22) -- Scientists have developed new systems for storing electrical energy derived from alternative sources that are, in some cases, 10 times more efficient than what is commercially available.
A window that washes itself? New nano-material may revolutionize solar panels and batteries, too
ScienceDaily (2009-12-04) -- Researchers have developed a method to control the atoms and molecules of peptides so that they "grow" to resemble small forests of grass. These "peptide forests" repel dust and water and can also serve as high-density battery capacitors.
Engineers on course to make super-efficient solar-electric powered boat
ScienceDaily (2009-12-09) -- A team of academics and students has begun work on a solar-electric powered boat which they claim will be one of the most sophisticated to enter the annual prestigious Solar Splash competition so far.
