In This Edition:
Space speedometer, concrete sphere sea batteries, using birds to gather data, making decisions under stress, and work less, for the climate!

Space Speedometer

Scientists at the Los Alamos National Laboratory and the U.S. Air Force have developed a speedometer device for space vehicles that measures the amount of space-plasma ions that hit both sides of the "dual-sensor laminated-head electrostatic analyzer", and measure the difference to calculate space speed.

Concrete Sphere Sea Batteries

The Fraunhofer Institute for Energy Economics and Energy System Technology have developed a battery system using hollow concrete spheres that can be placed on the sea bed. Energy is stored by pumping the water out of a sphere to make it hollow. When water is released back into the sphere, energy is generated by a turbine as the water goes back in.

Using Birds To Gather Data

Audubon published an interesting piece about how researchers are using birds as research assistants, to gather data and/or infer data from their movements and habits. Examples include checking the type of vomit thrown up by western gulls to track the movement of whales, and putting sensors on cormorants to track sea level depth changes.

Big Think published a useful video about how the CIA trains its operatives to make decisions when under stress using some simple rules, like do the next easy thing.

Work Less, For The Climate

Jack McGovan published a thought provoking piece on Sower about how working less is an often overlooked piece of climate action. Discussing his own experience and wider movements such as the 4-day work week, a valid case is made that working less reduces commuting emissions, employee burnout, while also increasing the chance for a balanced and happier lifestyle.
