Comments Off on LAGI announces location for 2018 renewable energy design competition

Energy infrastructure of the past, like oil refineries and rigs, aren’t typically considered beautiful. But as the world transitions to more renewable sources of power, what if utility-scale energy installations could double as art ? That’s the dream pursued by the Land Art Generator Initiative (LAGI), which holds a design competition every two years to present visions for energy-generating art able to power hundreds of homes. 2016’s winners included ethereal sailboats that harvested wind for power and fog for water, and a whale-inspired design generating wind, solar , and wave energy . LAGI just announced the location for their 2018 competition: Melbourne , Australia. LAGI is being sponsored by the State of Victoria to bring their 2018 contest to Melbourne, a city which hopes to be net zero by 2020. Artists, scientists, engineers, designers, and other creatives from around the world will be invited to submit designs tailored to the area for large-scale installations that add to the beauty of the area while generating clean energy . Related: Land Art Generator Initiative Santa Monica winners address California’s energy needs and drought One goal for these designs is to show how renewable energy installations, like solar and wind, can be integrated into the nature and culture of a region. LAGI2018 is part of Victoria’s Renewable Energy Action Plan under Action 13, which calls for “supporting important artistic and cultural sustainability events.” 2016’s top three winners included teams from Japan, Oregon, and Pennsylvania. The last four competitions – Dubai/Abu Dhabi in 2010, New York City in 2012, Copenhagen in 2014, and Santa Monica in 2016 – garnered over 800 submissions from more than 60 countries. The competition will launch in around six months, in January 2018, with submissions due in May. Public exhibitions will introduce some of the ideas to the people of Melbourne and nearby cities. According to LAGI, “2018 will be a year to celebrate the beauty of our sustainable future!” + Land Art Generator Initiative Images via Wikimedia Commons and courtesy of the Land Art Generator Initiative

Bio-inspired wind turbines with flexible blades 35% more efficient

Comments Off on Bio-inspired wind turbines with flexible blades 35% more efficient

Wind energy already yields four percent of Earth’s power, but five researchers at French institutions recently drew inspiration from nature to make wind turbines even better. Inspired by creatures like dragonflies, they found flexible blades on wind turbines make the machines much more efficient. Wind turbines today work best under optimal wind speeds, but the new bio-inspired design could offer a way around that fact, making wind power even more accessible. Wind speeds impact the functioning of a wind turbine. If the wind is too slow, the turbine won’t turn and generate energy; if the wind is too fast it could damage the turbine. Wind also must hit the turbines at the correct pitch angle to apply the correct amount of torque to the generator, according to Science. The new research from scientists at Sorbonne University and École Nationale Supérieure des Arts et Métiers-ParisTech fixes these issues with flexible blades much like insect wings. Related: Revolutionary flapping wind turbine mimics hummingbirds to produce clean energy The researchers constructed prototypes with regular hard turbine blades, slightly flexible turbine blades, and very flexible turbine blades. The last design turned out to be too floppy, but the slightly flexible blades outperformed the rigid ones, offering as much as 35 percent more power . They also continued to work in lower wind conditions and weren’t as susceptible to damage in high winds. The journal Proceedings of the Royal Society A published the research online in February. But the scientists’ work isn’t yet done: they now need to search for the right material that’s “flexible, but not too flexible,” according to lead author Vincent Cognet, to scale up the findings. Engineer Asfaw Beyene of San Diego State University, who was not part of this study, told Science, “The fluid mechanics and the physics make absolute sense. There’s no reason why we cannot make morphing blades that will adapt to wind conditions.” Via Science and Tech Xplore Images via Joi Ito on Flickr and Pexels

New wave energy generator taps into hard-to-reach low frequencies of the ocean

Comments Off on New wave energy generator taps into hard-to-reach low frequencies of the ocean

Wave power —energy harvested from ocean currents—is likely to be the next big thing in renewable energy generation, so researchers are spending quite a bit of time on new technologies to take advantage of the sustainable energy source. A new device has emerged that taps into hard-to-reach low frequencies of the ocean wave energy spectrum, utilizing energy that most harvesters cannot access. This makes it possible to draw even more power from calm, slow-moving seas, amplifying the potential of wave energy. Zhong Lin Wang of Georgia Institute of Technology created the new device to capture “blue energy,” another name for wave power. It’s a hybrid system that combines the efforts of two generators: an electromagnetic generator (EMG) and a triboelectric nanogenerator (TENG). EMG systems are the most common in existing wave energy harvesters, because they target high frequencies of fast-moving ocean currents. The more recently developed TENG technology is the one that taps into the lower frequencies, making Wang’s wave energy generator more efficient than existing models. By combining the two approaches, the generator captures a broader spectrum of ocean energy. Related: New Swedish wave energy buoy boasts 5x the output of existing technology “The TENG has the unique advantage of high output voltage, and its output power is linearly scaled with frequency, making it ideal for harvesting low-frequency energy,” Wang told Phys.org. “On the other hand, the EMG’s output power is proportional to the square of the frequency, so the EMG is ideally suited for harvesting high-frequency energy. At low frequency, (< 5 Hz), the effective output of the TENG is much higher than that of the EMG.” The research results were recently published in the journal ACS Nano .

Just 15-years-old, Angelo Casimiro has invented a new way to charge cell phones by harnessing the power of people’s steps . The industrious teen has invented a device inserted into a shoe that converts walking into piezoelectric energy, which allows users to power up their phones while on the go. The smart shoe not only creates energy from steps, but could provide important energy for off grid users or people living in developing countries that have minimal access to electricity.

When riding a stationary bicycle, it easy to feel as though you aren’t getting anywhere or doing much of anything other than managing a quick workout. The cardio is great, but what if you could capture the energy generated by all that pedaling? Instructables member KlockworkKevin has created an ingenious bike-powered generator hidden inside his patio furniture . When not in use, it is a colorful porch appointment that can be easily transformed into a power-making machine. As an added bonus to being unassuming and out-of-the-way, the generator is quieter than the previous models he built using noisy cordless drills.
