From Claims Journal via a retired insurance adjuster and friend:
An electronics engineer who moved to the Dallas area from Chicago decided that he had to do something about Texas’ stormy weather after both his GMC Jimmy and his wife’s Acura Integra were damaged by hail. Six years ago, Michael Siciliano launched the patented Hailstorm Protector System, an inflatable canvas car cover that prevents damage by deflecting hailstones.
A cool, simple idea. It might help with debris flung by a tornado as well. I wonder if it’s reusable.
