Crowdfunding has come to the small wind generation field with an Indiegogo campaign intended for an interesting target niche: a small wind generator designed to be clipped onto solar panels. According to his pitch, Michael Ring has not only created a prototype, but calculated possible energy returns, targeted a price point and lined up suppliers for initial deliveries and has turned to Indeigogo to get his small startup off the launch pad.  Read More

At this year's recent Dwell on Design event, LivingHomes unveiled its newly updated C6 series of prefabricated sustainable dwellings. Each of the three homes that comprise the C6 series are capable of achieving LEED Platinum certification, and can be outfitted with various optional extras to suit budget and needs.  Read More

John Dabiri has hypothesized and tested counter-rotating arrays of vertical axis wind turb...

Since we first looked at John Dabiri's hypothesis that vertical axis wind turbines should be arrayed like a school of fish to reduce the land area required for wind farm installations, the MacArthur Genius Grant recipient has continued to work on the idea. Following the latest round of coverage, Gizmag takes a deeper look at his concept, and wonders whether the idea of packing turbines into as tight a space as possible might overlook some wind energy fundamentals.  Read More

The ARES system uses electric locomotives as a form of energy storage

We’ve recently looked at ocean-based energy storage system concepts from MIT and Subhydro AS that are designed to overcome the intermittency problems of renewable energy sources like wind and solar by pumping water out of large tanks and using gravity to let it back in and generate electricity when needed. Santa Barbara, California-based company Advanced Rail Energy Storage (ARES) has come up with a land-based alternative that would provide grid scale energy storage using electric locomotives.  Read More

The Samsung GT-E2121B mobile phone that researchers powered with urine

If asked what would be a great power source for mobile phones, it’s a fair bet that most people wouldn't make urine their first choice. But that's exactly what a group of scientists at Bristol Robotics Laboratory in the UK have done. As part of a project to find new ways to provide electricity for small devices in emergency situations and developing countries they have created a new fuel cell system powered by pee.  Read More

The Change Initiative building (Photo: Gundeep Singh)

The Change Initiative is Dubai's first retail store to focus its efforts solely on selling sustainable products and services, so it's not too surprising that its owners asked architectural firm HOK to make the premises as green as possible. However, what's remarkable, is that The Change Initiative is reportedly being hailed as the world's most sustainable building, when assessed according to the LEED standard.  Read More

The current wing is an inflateable wing specially built by a kitesurfing manufacturer for ...

The University of Delft has a program devoted to kite-based generation systems, with 20 years of research and development under their belt since Wubbo Ockels, the first Dutch astronaut established it. Now, members of the team are exploring practical niches where the compromises of kite-based power might pay off. One has just completed a trip through Kenya, Tanzania and Senegal discussing opportunities for rural African kite generation with governmental agencies, universities and companies in the renewables space.  Read More

Li-ion batteries may be ok for your smartphone, but when it comes to large-scale energy storage, the priorities suddenly shift from compactness and cycling performance (at which Li-ion batteries excel) to low cost and environmental feasibility (in which Li-ion batteries still have much room for improvement). A new "wood battery" could allow the emerging sodium-ion battery technology to fit the bill as a long-lasting, efficient and environmentally friendly battery for large-scale energy storage.  Read More

NRG's Power2Serve

One of the pressing needs in the event of a large-scale disaster or emergency is power. With Power2Serve, energy provider NRG is addressing this need head on in the form of 68 feet (21 m) of truck and trailer equipped with 40 kW of electrical generation and a Wi-Fi pavilion which people can use to communicate and keep abreast of events.  Read More

SolePower and its ankle strap battery

Two years ago, University of Wisconsin–Madison engineering researchers Tom Krupenkin and J. Ashley Taylor developed a device designed to harness the power of walking to charge an internal battery. Now, a new product called SolePower is looking to do the same thing, and its designers are turning to Kickstarter to bring it to the masses. The difference between this and other devices is that it comes in the form of a removable insole, so it can be used in different kinds of shoes.  Read More
