Airborne wind energy systems use kites flown hundreds of metres in the air, where wind speeds are much faster, to generate electricity. One type uses small wind turbines mounted on a rigid kite (like an aeroplane wing), and the electricity is sent through the kite’s tether. Kitekraft’s model works similarly, but its turbines are dual purpose; the turbines act as propellers, allowing the kite to hover until it reaches the proper height. These systems will likely be most useful to the military and those living off the grid. Read full article here

To curb drug deaths, communities turn to Reddit, texts and wastewater
With drug overdose deaths on the rise, authorities are attempting to curb the epidemic by tracking and sharing information in real time. In one unique effort, a nonprofit in New York City is using drug-testing equipment and stamping or marking habits of dealers to identify drug batches that may endanger users. Other approaches are also being used, such as monitoring drug-related chatter on Reddit and analyzing local wastewater for opioid and other drug levels. With the combination of these efforts, researchers hope to put a dent in the opioid crisis and reduce overdose deaths. Read full article here
