University of Sydney charges ahead on zinc-air batteries
August 15, 2017 02:12 PM - University of Sydney

University of Sydney researchers have found a solution for one of the biggest stumbling blocks preventing zinc-air batteries from overtaking conventional lithium-ion batteries as the power source of choice in electronic devices.

Zinc-air batteries are batteries powered by zinc metal and oxygen from the air. Due to the global abundance of zinc metal, these batteries are much cheaper to produce than lithium-ion batteries, and they can also store more energy (theoretically five times more than that of lithium-ion batteries), are much safer, and are more environmentally friendly.

Jackdaws flap their wings to save energy
August 11, 2017 10:05 AM - Lund University

For the first time, researchers have observed that birds that fly actively and flap their wings save energy. Biologists at Lund University in Sweden have now shown that jackdaws minimise their energy consumption when they lift off and fly, because the feathers on their wing tips create several small vortices instead of a single large one. The discovery could potentially be applied within the aeronautical industry.

Night vision for bird- & bat-friendly offshore wind power
August 11, 2017 09:55 AM - Pacific Northwest National Laboratory

The same technology that enables soldiers to see in the dark can also help protect birds and bats near offshore wind turbines.

Night vision goggles use thermal imaging, which captures infrared light that's invisible to the human eye. Now, researchers at the Department of Energy's Pacific Northwest National Laboratory are using thermal imaging to help birds and bats near offshore wind farms. PNNL is developing software called ThermalTracker to automatically categorize birds and bats in thermal video. Birds and bats fly over offshore waters, but they're difficult to track in such remote locations.

RAVAN CubeSat Measures Earth's Outgoing Energy

An experimental small satellite has successfully collected and delivered data on a key measurement for predicting changes in Earth’s climate.

Power-to-Liquid: 200 Liters of Fuel from Solar Power and the Air's Carbon Dioxide
August 9, 2017 08:17 AM - Karlsruhe Institute of Technology

Production of liquid fuels from regenerative electric power is a major component of the energy turnaround. The first 200 l of synthetic fuel have now been produced from solar energy and the air’s carbon dioxide by Fischer-Tropsch synthesis under the SOLETAIR project. Here, INERATEC, a spinoff of Karlsruhe Institute of Technology (KIT), cooperates with Finnish partners. The mobile chemical pilot plant that can be used decentrally produces gasoline, diesel, and kerosene from regenerative hydrogen and carbon dioxide. It is so compact that it fits into a shipping container.

Annual Wind Power Report Confirms Technology Advancements, Improved Project Performance, and Low Wind Energy Prices
August 8, 2017 03:47 PM - DOE/Lawrence Berkeley National Laboratory

Wind energy pricing for land-based, utility-scale projects remains attractive to utility and commercial purchasers, according to an annual report released by the U.S. Department of Energy and prepared by the Lawrence Berkeley National Laboratory (Berkeley Lab). Prices offered by newly built wind projects in the United States are averaging around 2¢/kWh, driven lower by technology advancements and cost reductions.
