Hydrogen Gas Fueled Vehicles A Step Closer
February 27, 2008 09:41 AM - University of California - Los Angeles

While liquid hydrogen is denser and takes up less space, it is very expensive and difficult to produce. It also reduces the environmental benefits of hydrogen vehicles. Widespread commercial acceptance of these vehicles will require finding the right material that can store hydrogen gas at high volumetric and gravimetric densities in reasonably sized light-weight fuel tanks.

Tree Blocks: Building imagination with reclaimed trees
February 27, 2008 09:31 AM - , The Alternative Consumer

While cleaning the kids’ playroom for what must be the umpteenth time today I spied the bag of Tree Blocks that our entire family loves to build with. These unusual building blocks are cut from tree branches and make the most beautiful sculptures, keeping little hands busy for at least long enough for me to get a shower. The “elves” at Tree Blocks identify abandoned or end of productive cycle plots of apple, cherry and hazelnut trees and contact the farmers. They then push the old trees over removing the roots. Tree Blocks bridges and blocks are made from the wood purchased and processed by the “elves.” This leaves the farmer clean soil and seed money, so he can get back into production.

BEIJING (Reuters) - China's largest plastic bag maker has closed following a state-led environmental campaign discouraging plastics use, Xinhua news agency said on Tuesday. China launched a surprise crackdown on plastic bags in January, banning production of ultra-thin bags and forbidding its supermarkets and shops from handing out free carrier bags from June 1.

Could Waste Heat From Car Exhausts Be Recycled To Help Power Cars?
February 25, 2008 10:03 AM - Cardiff University

Professor Mike Rowe's long term research interest at the Cardiff School of Engineering has been in thermoelectric generation - employing thermocouples to convert heat into electricity. The conversion technology is used in everyday applications such as controlling the central heating system or refrigerator temperature.

New solar technology greatly improves performance
February 25, 2008 09:40 AM - ENN

A new coating for solar panels could lead to more efficient solar collection. The energy from sunlight falling on only 9 percent of California’s Mojave Desert could power all of the United States’ electricity needs if the energy could be efficiently harvested, according to some estimates. Unfortunately, current-generation solar cell technologies are too expensive and inefficient for wide-scale commercial applications.

Using organic fertilizers could protect against climate change
February 25, 2008 09:25 AM - ENN

Los Angeles, London, New Delhi, and Singapore (25 February, 2008) — Applying organic fertilizers, such as those resulting from composting, to agricultural land could increase the amount of carbon stored in these soils and contribute significantly to the reduction of greenhouse gas emissions, according to new research published in a special issue of Waste Management & Research (Special issue published today by SAGE).

China orders listed firms to be greener

HONG KONG (Reuters) - An Australian subsidiary of CLP Holdings Ltd, the larger of Hong Kong's two power utilities, has agreed with Melbourne-based Solar Systems to develop the world's largest solar power station. TRUenergy will contribute an initial A$7 million ($6.5 million) to develop a 2-megawatt heliostat concentrated photovoltaic pilot plant, subsequently investing up to A$285 million to build the remaining stages of the 154 megawatt project in northern Victoria, Australia, CLP said.

China may hit energy use target for 1st time in 08
February 25, 2008 04:13 AM - Reuters

KUNMING (Reuters) - China could meet its own annual targets for energy efficiency for the first time this year, but will still have problems meeting its goals of reducing emissions, according to a state-backed think tank. China in 2006 set a goal of cutting energy intensity, or the amount of energy needed to produce $1 in economic growth, by 20 percent by 2010. But after it failed to meet the annual target in 2006, the first year of the campaign, it has not published the annual goals for subsequent years.
