How Much Natural Gas Leaks? How Much Natural Gas Leaks?

 Snaking beneath the surface of many Eastern cities is a network of aging, cast-iron pipes carrying natural gas. The pipes, buried underground, have been shifted for decades by winter freeze-thaw cycles, and some are simply cracked from age. Because of this, some pipes leak.

Just how much gas from those older pipes and their newer replacements in the pipeline distribution system leaks out and rises into the atmosphere..http://www.scientificamerican.com/article.cfm?id=how-much-natural-gas-leaks

New Technology Enables Crops to Take Nitrogen from Air.. New Technology Enables Crops to Take Nitrogen from Air..

 A major new technology has been developed by The University of Nottingham, which enables all of the world's crops to take nitrogen from the air rather than expensive and environmentally damaging fertilisers.

Nitrogen fixation, the process by which nitrogen is converted to ammonia, is vital for plants to survive and grow. However, only a very small number of plants, most notably legumes (such as peas, beans and lentils) have the ability to fix nitrogen from the atmosphere with the help of nitrogen fixing bacteria. The vast majority of plants have to obtain nitrogen from the soil, and for most..
 

Removing Pollutants and Contaminants from Wastewater Removing Pollutants and Contaminants from Wastewater

The Fraunhofer Institute for Interfacial Engineering and Biotechnology IGB and its European partners have developed several effective processes for eliminating persistent pollutants from wastewater. Some of these processes generate reactive species which can be used to purify even highly polluted landfill leachate while another can also remove selected pollutants which are present in very small quantities with polymer adsorber particles.

Climate change is affecting the spread of infectious diseases Climate change is affecting the spread of infectious diseases

 

Climate change is affecting the spread of infectious diseases worldwide, according to an international team of leading disease ecologists, with serious impacts to human health and biodiversity conservation. Writing in the journal Science, they propose that modeling the way disease systems respond to climate variables could help public health officials and environmental managers predict and mitigate the spread of lethal diseases.

Puerto Rico sees more rain, wetter times to come Puerto Rico sees more rain, wetter times to come

Puerto Ricans are used to wet tropical weather, but the past few weeks have unleashed a series of storms of almost biblical proportions, destroying hundreds of homes, sweeping away cars and leaving tens of thousands without power.

The latest national eGallon price is $1.18, as compared to $3.49 for a gallon of unleaded gasoline. In June, the Department of Energy launched the eGallon to help inform EV drivers how much they can save by fueling their cars with electricity instead of gasoline. Our popular eGallon tool allows consumers to see the difference in eGallon and gasoline prices state by state.

This update comes as Energy Secretary Ernest Moniz today highlighted the continued growth of electric vehicle sales -- doubling in the first six months of 2013 compared to the same period in 2012. In fact, according to numbers from Argonne National Lab and the Hybrid Market Dashboard, June’s EV sales were the strongest on record for the United States.

Charge your Smartphone with new Solar Film Technology Charge your Smartphone with new Solar Film Technology

Solar technology is an innovation that will both benefit the environment and the consumer market.

Smartphones that have little battery life could become a thing of the past, when companies have the technology to be able to use the unlimited resource of the sun to constantly recharge devices.

Researchers at UCLA have designed a two layer, solar film that could be applied to windows, sunroofs or smartphone displays due to its transparency.

Tiny Channels of Water Could Cool Windows Tiny Channels of Water Could Cool Windows

A new  system out of Harvard harnesses channels of running water to cool windows that receive a lot of sun. The water carries away heat, leading to less work for air conditioners and a lower electricity bill.

The channels are ultra-thin and encased in a sheet of clear silicone rubber that is stretched over a window. They crisscross to create a mesh-like pattern. While the channels are visible when empty, they become transparent when they contain.

Harnessing the Net to Power a Green Revolution Harnessing the Net to Power a Green Revolution

A new breed of digital start-ups is harnessing the power of the Internet to make smarter, more efficient use of energy and other resources.

Proponents call it “cleanweb,” and they say the sector is poised to bring about huge leaps in efficiency, saving money and cutting planet-warming carbon emissions.

As its backers define it, cleanweb is any software or Internet application that makes it easier to use resources — like textiles or cars or electricity — more efficiently.

Tesla Shows Off A 90-Second Battery Swap System Tesla Shows Off A 90-Second Battery Swap System

Tesla teased electric motorheads earlier this week by announcing an event that would show off its curious battery-swapping system, and it wound up being even more impressive than most of us imagined. Long story short, Tesla can swap a Model S’s battery in just 90 seconds (that’s less time than it takes to fuel up a regular car), and you won’t even have to get out of your seat to do it.
