Sky WindPower's Flying Electric Generators

submitted by: Len Shepard
The video shows the concept, benefits and progress of developing flying electric generators to convert the persistent and abundant power in high altitude winds (aka the jet stream) into electricity. It includes interviewers with inventors Dr. Bryan Roberts, who originally conceived the idea, David Shepard, who convinced Dr. Roberts to jointly form Sky WindPower, and the engineers who are building and testing prototypes today. The video shows an actual runway tow test where electricity was...

Order in Spontaneous Behavior

submitted by: brembs
Brains are usually described as input/output systems: they transform sensory input into motor output. However, the motor output of brains (behavior) is notoriously variable, even under identical sensory conditions. The question of whether this behavioral variability merely reflects residual deviations due to extrinsic random noise in such otherwise deterministic systems or an intrinsic, adaptive indeterminacy trait is central for the basic understanding of brain function. Instead of random...
