hey everyone,

i ran across this story about a new development in wind turbines that does
not chop up birds and bats in mid-flight:

http://grist.org/news/this-wind-turbine-has-no-blades-and-thats-why-its-better/

although each device is less efficient at capturing wind energy, wind farms
can cram more of these things into a given space, which translates into
more wind being harnessed for energy overall. it's also cheaper than the
bladed wind turbines and it might also be easier to clean and maintain.

weirdly, the inspiration for this turbine was the tacoma narrows bridge!
