BarotraumaWikipedia.org

Barotrauma is physical damage to body tissues caused by a difference in pressure between an air space inside or beside the body and the surrounding fluid.

Barotrauma typically occurs to air spaces within a body when that body moves to or from a higher pressure environment, such as when a SCUBA diver, a free-diving diver or an airplane passenger ascends or descends, or during uncontrolled decompression of a pressure vessel.

“Construction of a 150-turbine wind farm on 20,000 acres along Wolverine Canyon [Blackfoot Mountains] has been approved by Bingham County commissioners.”

The turbines would be 490 feet tall!! I wonder if there are any taller ones anywhere?

This project is remaking some traditional political alliances in the area. Leading the charge against the farm is Frank VanderSloot, owner of Melaleuca Inc.  He is a major Eastern Idaho Republican influential and a landowner in the area

BLM holding public meetings on massive wind farm on Browns Bench

I was just in this country. It is not well known, but scenic and wildlife rich public land.

Given the abundance of windy private lands, why don’t they build their wind farms there and make the landowner some money.
