Low-level jets create winds of change for turbines
Global wind power capacity has increased more than fivefold over the past decade, leading to larger turbines, but low-level jets are one cause for concern. The effects of these strong, energetic wind flows depend on how high the wind flows are in relation to the turbines. In the Journal of Renewable and Sustainable Energy, researchers considered three different scenarios in which the LLJs were above, below, and in the middle of the turbine rotors. (2021-02-23)

Fast-flying bats rely on late-night updrafts to reach great heights
Although scientists knew that some bats could reach heights of over 1,600 meters (or approximately one mile) above the ground during flight, they didn't understand how they managed to do it without the benefit of thermals that aren't typically available to them during their nighttime forays. Now, researchers reporting in the journal Current Biology on February 4th have uncovered the bats' secret to high-flying. (2021-02-04)

Now, researchers reporting in ACS' Nano Letters have made a prototype of an anode-free, zinc-based battery that uses low-cost, naturally abundant materials. (2021-01-20)

Butterfly wing clap explains mystery of flight
The fluttery flight of butterflies has so far been somewhat of a mystery to researchers, given their unusually large and broad wings relative to their body size. Now researchers at Lund University in Sweden have studied the aerodynamics of butterflies in a wind tunnel. The results suggest that butterflies use a highly effective clap technique, therefore making use of their unique wings. This helps them rapidly take off when escaping predators. (2021-01-20)

Two-photon polymerization of PEGda hydrogel microstructure with low threshold power with green laser
The fabrication of shape-memory hydrogel scaffolds not only requires biocompatibility, micrometre resolution, high mechanical strength, but also requires a low polymerisation threshold in high-water content environment to incorporate microstructures with biological tissues. Towards this goal, scientists from China and australite developed a new hydrogel formula that full fills this goal and demonstrated water-responsive structures with a shape-memory effect at a micrometre scale. This work is of importance for the development future reversible microdevices in biomedical engineering. (2021-01-20)

Could "Power Walking" fuel the energy revolution? India is ready to step up
India has an energy problem. It currently relies heavily on coal and consumer demand is expected to double by 2040, making its green energy targets look out of reach. Part of the solution could come from harvesting energy from footsteps, say Hari Anand and Binod Kumar Singh from the University of Petroleum and Energy Studies in Dehradun, India. Their new study, published in the De Gruyter journal Energy Harvesting and Systems, shows that Indian attitudes towards power generated through piezoelectric tiles are overwhelmingly positive.
