Wind Catcher
The people from Wind Catcher say their product is “perfect for camping, RVing, and off-grid living. It’s lightweight, easy to install, and produces enough energy to power your devices and appliances for days.”
Of course, “easy to install” is a relative term, but, with all those stays and anchors, it doesn’t look at all easy to me.
And, considering this sells for $1849, I’ll stick with a portable solar PV array.
