Gravia uses a slowly sinking weight to charge 10 high-output LEDs, which fire into the acrylic lens and create a diffuse light output of 600-800 lumens, roughly equal to a 40-watt incandescent bulb. The LEDs are activated only a few seconds after the process begins, and the entire operation is silent.  Read More

Office Depot Breaks Ground on Company's first 'Green'  Store

February 20, 2008 Office Depot plans to open its first "green" LEED-Certified Store and the company recently celebrating breaking ground on the Austin, Texas site.

February 4, 2008 Cleantech America Inc. has received formal approval from the California Public Utilities Commission for its CalRENEW-1 solar facility. Due to begin operation in the spring of 2009, the plant is the largest utility-scale photovoltaic (PV) solar facility being developed under California’s Renewables Portfolio Standard program.  Read More

Air Launcher JET Alpha nozzle

February 1, 2008 In an era where the need to reduce, reuse and recycle is a the top of the agenda, any innovation that helps in this regard is a welcome one. In providing a solution to the specific problem of recycling aerosol cans, Tokyo-based company CC Medico has developed the Air Launcher JET Alpha nozzle, a new type of aerosol nozzle which is easily removed and separated from the can by hand, which makes recycling the cans much easier.  Read More

HP advances recycling techniques for ink cartridge manufacture

January 31, 2008 HP has developed engineering technology that enables it to use post-consumer recycled plastics in the production of new its inkjet print cartridges. To date more than 200 million cartridges have been manufactured using the process and materials used include multiple sources and grades of recycled plastics – from everyday water bottles to used HP inkjet cartridges.  Read More

January 30, 2008 Technology giant Intel has announced it will purchase more than 1.3 billion kilowatt hours a year of renewable energy certificates, making it the single-largest corporate purchaser of green power in the US. The decision is part of a Intel's multi-faceted approach to reduce impact on the environment, and places the company at the top of the EPA's Green Power Partners latest Green Power Partners Top 25 list.  Read More

Energy Island sketch

January 29, 2008 Ocean Thermal Energy Conversion uses the temperature difference between surface and deep-sea water to generate electricity – and though it has an efficiency of just 1-3% - researchers believe an OTEC power plant could deliver up to 250MW of clean power, equivalent to one eighth of a large nuclear power plant, or one quarter of an average fossil fuel power plant. Architect and engineer Dominic Michaelis and his son Alex, along with Trevor Cooper-Chadwick of Southampton University are developing the concept with plans of putting the theory to the test on an unprecedented scale by building a floating, hexagonal Energy Island that will harness energy from OTEC, as well as from winds, sea currents, waves, and the sun.  Read More
