Good news on a technology that could revolutionize geothermal energy made waves at the American Geophysical Union meeting last week. Anyone who understands that the world's hunger for energy will push our planet beyond the point of no return without technological solutions will welcome the idea of CO2 plume geothermal power or CPG.

New recycling technology will allow paint to be recycled cost effectively and on a large scale, according to UK design company Seymourpowell, working with Dulux paint-brand owner AkzoNobel and Newlife Paints to create this technology.

More than 70 different technologies are available to improve the efficiency of a trucking fleet. These include changes to powertrains and chassis, low-rolling-resistance tires, and enhanced tractor aerodynamics. Finding the right mix to improve a specific fleet can be daunting. Carbon War Room partnered with the North American Council for Freight Efficiency (NACFE) to publish a series of Confidence Reports-objective assessments of the fuel efficiency savings of these technologies. The reports were cited by U.S. EPA in its Greenhouse Gas Pollution Prevention rule-making proposal. 

With carbon dioxide emissions continuing to rise, an increasing number of experts believe major technological breakthroughs - such as CO2 air capture - will be necessary to slow global warming. But without the societal will to decarbonize, even the best technologies won't be enough.

Norsepower Oy and Bore say the sea trial of Norsepower's Rotor Sail - a new wind propulsion technology for ships - verified by NAPA and supported by VTT Technical Research Centre of Finland, confirm fuel savings of 2.6 percent using a single small Rotor Sail on a route in the North Sea. With these fuel savings, the technology has a payback period of 4 years, the companies say.

MGM Resorts is making water conservation a top priority in developing its Park promenade in Las Vegas -- even though there's a relative paucity of water-conservation technologies compared with the number of energy-efficiency technologies now available, says Chief Sustainability Officer Cindy Ortega. MGM also launched a social app to raise employee awareness about water conservation.

Direct Metal Laser Sintering (DMLS), an aerospace production technology, has the potential to build light, sustainable parts and reduce a company's carbon footprint, according to a study by EOS and Airbus Group Innovations, previously EADS Innovation Works.

Kodak's Sonora Process Free Plate technology could save up to 265 million liters of water in a year, the company says.

Electric car maker Tesla Motors is handing over the keys to its technology in an unusual effort to encourage other automakers to expand beyond gasoline-burning vehicles.

Ford expanded the use of its near-dry machining technology to 6 additional manufacturing plants worldwide. When applied to engine production, Ford claims the technology uses 50% less water and 80% less oil than traditional methods.

Carigali-PTTEPI Operating Company Sdn. Bhd. is saving $52 million annually at its natural gas development platform in the Gulf of Thailand, while reducing water consumption and chemical use through General Electric's advanced cooling and chemical treatment technology.

Transport for London has today (Wednesday 27 August) announced that it is to trial innovative technology that will enable specially designed buses to wirelessly charge their batteries while they wait at bus stands.

Taking plastics recycling to a whole new level, Procter & Gamble (P&G) has pioneered a new technology that restores used polypropylene plastic (PP) to 'virgin-like' quality. Developed in P&G labs, the patented technology is being licensed to PureCycle to deploy in a new recycling plant in Lawrence County, Ohio and will allow consumers to purchase more products made from recycled plastic.

London's Heathrow Airport has saved more than 130 million liters of water annually using General Electric's water treatment technologies, GE says, adding that its technologies also saved the UK's largest airport $310,000 in a year.

Newlight Technologies is doing. Its patented technology extracts carbon from the air and converts it into long-chain polymers that can be used as substitutes for oil-based plastics.

Wal-Mart has introduced a line of "all-natural," chemical-free cleaning products under its Great Value label. The products, which are priced more cheaply than brand-name eco-friendly cleaning products, use Wal-Mart's proprietary Evolve technology, which the company says allows the products to work as effectively as petroleum-based cleaners.

Clean-technology accelerator the Cleantech Open has awarded PowWow Energy (pictured) the Grand Prize Cleanie award worth $200,000 for the Top Cleantech Entrepreneur of the year. PowWow Energy has developed technology that enables farmers and ranchers to quickly detect water leaks that can destroy an entire crop or cause thousands of dollars of damage.

Some scientists and analysts are touting carbon capture and storage as a necessary tool for avoiding catastrophic climate change. But critics of the technology regard it as simply another way of perpetuating a reliance on fossil fuels.

Telecom Alaska Communications earned a 225% return on investment over 7 months by integrating energy data management services from technology company Ecova. Alaska Communications used the technology to better understand energy consumption and spending in its operations.

Technological advances have made removing salt from seawater and waste water less energy-intensive, but will they simply encourage us to use more?
