Researchers have developed a technique to move objects around with a jet of wind. The new approach makes it possible to manipulate objects at a distance and could be integrated into robots to give machines ethereal fingers.

Interactions between wind turbines could reduce power output by 30% in proposed offshore wind farm areas along the East Coast, new research has found. In all, the farms could still meet 60% of the electricity demand of New England.

Wind power is a source of energy that is both affordable and renewable. However, decision-makers have been reluctant to invest in wind energy due to a perception that wind farms require a lot of land compared to electric power plants driven by fossil fuels. Research was based on the assessment of the land-use of close to 320 wind farms in the U.S. paints a very different picture.

With climate change and rising urbanization, the likelihood and severity of urban flooding are increasing. But not all city blocks are created equal. Researchers investigated how urban layout and building structures contribute to pedestrian safety during flooding. Based on their simulated results, the team recommends modifying building corners and protective block layouts to reduce pedestrian risk.

Researchers have used a genetic learning algorithm to identify optimal pitch profiles for the blades of vertical-axis wind turbines, which despite their high energy potential, have until now been vulnerable to strong gusts of wind.
