February 5, 2008 The Airbus A380 has become the first commercial aircraft to complete a flight using liquid fuel processed from gas. GTL involves converting natural gas, which emits the least carbon of all the fossil fuels, to a liquid fuel oil, which can be used as a fuel substitute, or mixed with regular fuel. The three-hour flight from the UK to France was the first stage of a test flight program to evaluate the environmental impact of alternative fuels in the airline market.  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

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

Hunton Energy announces plans for clean energy plant

December 20, 2007 Finding new ways to capture environmentally harmful emissions and use them to generate power is a positive step in the effort to slow global warming. The latest news from this arena comes from Hunton Energy, which has announced plans to build and operate a Synthetic Natural Gas (SNG) plant at Dow’s Oyster Creek Facility on the Texas Gulf Coast which will capture 100 percent of its own CO2 emissions, using turbines to produce additional power from its byproduct steam.  Read More

Preparing to deploy an Argo float from a research vessel

December 11, 2007 With rising concerns over climate change and its regional impacts, understanding (and eventually predicting) changes in both the atmosphere and ocean are needed to guide international actions, to optimize governments’ policies and to shape industrial strategies. Argo is a program that brings together more than 25 countries and thousands of floating sensors to provide key data from the ocean and assist in achieving these goals.  Read More

Solar-powered RFID readers and signposts

November 20, 2007 Lockheed Martin subsidiary Savi Technology has begun deploying solar-powered Radio Frequency Identification (RFID) readers and signposts, saving energy and negating the need for installing electrical infrastructure in remote areas.  Read More

Solar schools: Standley Middle School (147 kW) in San Diego

November 16, 2007 The sunny state of California continues to lead the way in solar energy production. In January, the state launched a 10-year Solar Initiative program offering $2.1 billion in rebates for residential and commercial solar systems. The uptake of clean energy is also forging ahead in the public sector, with the latest announcement coming from Santa Cruz County where UPC Solar has won a contract for a 950kW project in the city school system.  Read More

Green Earth Technologies G-Oil™

November 6, 2007 Green Earth Technologies has announced a completely biodegradable motor oil which the company claims is the “first bio-based, high-endurance motor oil to provide superior performance during the maximum oil change interval recommended by vehicle manufacturers”.  Read More

Ventilation air methane (VAM) system

November 5, 2007 A new power plant that generates electrical power using ventilation air methane (VAM) from coal mining is now in operation. The technology significantly reduces harmful emissions of methane (a gas 20 times more potent than CO2) released in the mining process, while producing power that can be delivered to the grid or used directly in the mine.  Read More
