How Do They Get So Much Money for Grid Ties?

[Bret Cahill]

Are there still some unexpired patents out there?

Does a grid tie require a 200 lb copper coil?

It is probably because of the extensive testing, certification, and
liability issues of a device that connects to the utility company grid, and
which has "potentially" life threatening implications if it fails to work as
required. Something like the latest pill (such as Celebrex) which probably
costs $0.10 to make and they sell for $3 a poop. (Oops, that's for a
laxative!)
