Teaching Wind Turbines Altruism to Rev-up Wind Farms

“Logic clearly dictates that the needs of the many outweigh the needs of the few.” So declares Spock, Star Trek’s Vulcan hero, as he sacrifices himself to save the Starship Enterprise and its crew in the 1982 film Star Trek: The Wrath of Khan. Today Stanford University researchers presented the clearest proof to date that self-sacrifice can also benefit wind farms. In their demonstration at an Alberta wind farm, one turbine sacrifices a fifth of its generating potential to enable better performance by neighboring turbines, boosting the group’s collective output.

And while Spock’s heroics necessitated a major plot twist to revive his character for the next Star Trek sequel, teaching turbines to behave altruistically requires just a small (but intelligent) tweak to their control systems. What they learn is how to share the wind. Continue reading “Teaching Wind Turbines Altruism to Rev-up Wind Farms”

How Canada Should Return Obama’s Oil Pipeline Punt

Late last week President Barack Obama deferred consideration of the Keystone XL oil pipeline, designed to ship Alberta petroleum to the Gulf Coast, until after next year’s U.S. elections. Obama’s move immediately sparked vows in Canada to redirect crude exports to Asian markets less angst-ridden by the environmental impacts associated with tapping Alberta’s tough, tarry petroleum. A smarter strategy would be to reduce those impacts, starting with the black mark that brought Keystone XL to national attention: oil sands crude’s bloated carbon footprint.
