'If we can't comprehend the issue then we don't feel anything, therefore we don't act. I'm...

Around the world there are hundreds of millions of discarded mobile phones lying around in drawers and boxes, displaced by the bigger screen or better camera of the latest version. But truth be told, even if we were talking about hundreds of billions it would be unlikely to elicit a much different response, because ridiculously big numbers are ridiculously big numbers, right? Seattle-based photographer and activist Chris Jordan is on a mission to make these measures of consumerism manifest through visual art and, as he explained to Gizmag, bridge the disconnect between our mass consumption and its largely invisible consequences.  Read More

The world's largest solar thermal generation plant, Ivanpah Solar Electric Generating Syst...

After three years of construction, the Ivanpah Solar Electric Generating System (ISEGS) is now operational. The 392 MW plant, funded by NRG, Google, and BrightSource Energy, is expected to generate enough electricity to power 140,000 homes, each year. NRG announced last week that each of the plant's three units is now supplying electricity to California’s grid.  Read More

The Parasol system uses passive radar sensors and mathematical algorithms to determine if ...

With aspirations to claim 80 percent of its power from renewable sources by the 2050, it follows that Germany is taking a proactive approach to its clean energy transformation. Wind farms, while set to play an important part in achieving this goal, often meet impassioned opposition from disgruntled neighbors piqued by their perpetually blinking beacons. In an effort to address this issue, researchers have developed a sensor system for wind turbines which detects nearby aircraft, switching on a beacon warning system only as they approach.  Read More

Heat stored in the Pacific Ocean could be a ticking climate time bomb (Photo: Shutterstock...

Despite an overwhelming consensus among climate scientists that warming trends over the past century are most likely the result of human activities, some claim that a plateau in global surface air temperatures since 2001 is evidence to the contrary. However, a new study suggests the recent stabilization of air temperatures is a result of abnormally strong east to west trade winds, causing warmth to be stored temporarily beneath the western Pacific ocean.  Read More

The CRUTEM4 dataset provides Google Earth users with access to one of the most widely used...

Talking about the weather is a pastime as old as language, but climate researchers from the University of East Anglia (UEA) in the UK have just given people a whole lot more to talk about. As part of an ongoing effort to increase the accessibility and transparency of data on past climate and climate change, they've made one of the most widely used records of Earth's climate accessible through Google Earth.  Read More

Scientists have succeeded in converting plant waste to gasoline (Photo: Shutterstock)

By now, most people have at least a passing knowledge of biodiesel – it's diesel fuel made from plant or animal oils, as opposed to the more traditional and less eco-friendly petroleum. While it's a good choice for people with diesel-powered vehicles, those of us with gas-burning cars haven't been able to get in on the action ... although that may be about to change.  Read More

Stefanie Kring studies zooplankton gathered from wastewater lagoons

With dwindling non-renewable fuel sources creating an enormous energy challenge, the search is on to develop sustainable, renewable types of energy such as solar, wind and biofuel. One of the recent developments in this field comes from New York's Clarkson University, where new findings suggest that small organisms found in wastewater treatment lagoons could be used as biofuel feedstock.  Read More

The optical sensor system developed to detect the amount of salt on a road (Photo: UC3M)

Just as a good meal can be ruined by too much table salt, too much sodium chloride applied to road surfaces to prevent icing can have a detrimental effect on vehicles, infrastructure and the environment. Engineers at Spain's Carlos III University (UC3M) have developed an optical sensor intended to prevent excessive salt treatment by detecting the amount of salt already on the road in real time.  Read More

The humidity-driven flexing of a spore-covered piece of latex rubber (right) drives the mo...

Ozgur Sahin believes that water evaporation is the largest power source in nature. In an effort to demonstrate the potential of this untapped resource, Sahin and his fellow researchers have created prototype electrical generators with rubber sheets that move in response to changes in humidity thanks to a coating of bacterial spores.  Read More

The Salicornia is one species of halophyte that is a promising feedstock for biofuel produ...

Whenever the topic of plant-derived biofuels is raised, the issue of turning valuable arable land over to the task of growing feedstock is generally not far behind. A discovery by the Sustainable Bioenergy Research Consortium (SRBC) that desert plants fed by seawater can produce biofuel more efficiently than other well-known feedstocks could help alleviate such concerns.  Read More
