Solar power may provide a clean, abundant source of energy, but we know the sun's rays are capable of much, much more. Aside from generating electricity, we've seen solar energy harnessed to produce drinkable water as well, so why not combine the two processes into one system? That's what IBM and its collaborators are hoping to do with an affordable High Concentration PhotoVoltaic Thermal (HCPVT) system that uses cooling technology from supercomputers to harvest solar energy more efficiently and produce purified water at the same time.  Read More

A newly-developed roof panel both reflects sunlight, and emits heat drawn from the buildin...

Studies have already shown us how white-painted roofs can help cool buildings by reflecting sunlight, while "green" roofs beat the heat by blocking sunlight and providing a source of evaporative cooling. Now, a team of scientists from Stanford University have created a panel that not only reflects sunlight, but it also draws heat from within the building and emits it into outer space.  Read More

Data center efficiency is quite the hot topic these days, and companies are keen to emphasize their green credentials. Rather than releasing their stats on a quarterly basis like most other companies, Facebook has launched a new live dashboard showing the efficiency of its Oregon and North Carolina facilities, and the numbers speak for themselves.  Read More

Lockheed Martin and Reignwood Group plan to develop a 10 MW prototype OTEC pilot plant off...

Lockheed Martin has been getting its feet wet in the renewable energy game for some time. In the 1970s it helped build the world’s first successful floating Ocean Thermal Energy Conversion (OTEC) system that generated net power, and in 2009 it was awarded a contract to develop an OTEC pilot plant in Hawaii. That project has apparently been canceled but the company has now shifted its OTEC sights westward by teaming up with Hong Kong-based Reignwood Group to co-develop a pilot plant that will be built off the coast of southern China.  Read More

Bill Gray is looking to the past to reinvent the future of energy storage with a new take ...

It's no secret that the successful future of wind, solar and other renewable sources hinges on the development of cost effective energy storage systems. Silicon Valley inventor Bill Gray believes his novel approach to flywheel technology could be the answer.  Read More

Researchers in Australia have developed the PowerWINDows, a new type of wind turbine that ...

Wind farms may be hitting the big time, but that hasn't deterred inventors and technologists from tinkering, or even reinventing, the turbine itself. In the past few months we've seen wind energy systems that use discs attached to hydraulics and even charged water droplets, but how about skyscrapers outfitted with rotating window panels? This is the idea behind the University of Wollongong's PowerWINDows concept, a modular wind turbine designed to have less of an impact on the surrounding environment.  Read More

The pedal-powered Popemobile concept from Yannick Read of the ETA

Shortly before that time of the year traditionally reserved for all manner of tomfoolery, the UK's Environmental Transport Association (ETA) released details of a pedal-powered Popemobile concept that many immediately assumed to be a joke. Gizmag caught up with its designer, Yannick Read of Hornster and Bond Bike fame, to find out if the environmentally-friendly pontiff-carrier proposal is genuine or fake.  Read More

What should you do with your old computer? Chances are that no one will want to buy it, but you don’t want to just throw it away – especially with e-waste being such a huge environmental concern. Recycling or donating are possibilities, but how do you know that all of your personal information is really deleted from its hard drive? Well, that’s where the Pass IT On For Good project comes in. It supplies you with a USB card that deletes all the personal content on your computer, installs educational software, and then instructs you on how to donate it for use in schools in developing nations.  Read More

Philip's Coen Liedenbaum shows off the 200-lm/W prototype LED tube

Back-to-back announcements from Green Ray LED and Philips show signs that there is now clear water between LED lights and fluorescent lights so far as energy efficiency is concerned. The proverbial glow of commercially available lights with 200 lumens per watt efficiency can now be clearly seen radiating over the horizon.  Read More

How do you measure the life of a light source that could last decades? (Photo: Shutterstoc...

Just over a week ago we reported that Philips' 22 W LED light bulb, designed as a like-for-like replacement of a 100-W incandescent light bulb, was the first LED bulb of its type to receive the stamp of approval from Energy Star. But looking at the Energy Star requirements reported by Philips in its press release, it seemed a little strange that Philips' product is the only one to have been certified – given that products long on the market appear, at face value, to meet those requirements. Since then, Gizmag has spoken to LED light bulb makers Switch Lighting and other industry players to find out why they're apparently playing catch-up.  Read More
