I was contacted by Sally, yet another inventor with a brilliant idea. Rainwater HOG is a modular rainwater rescue tank that can be installed horizontally or vertically, as a thermal mass or drinking water supply.
The trouble (according to Sally) is that water in the US (as opposed to Australia, where she comes from) is too cheap, which makes it hard for her to sell her capital-intensive water conservation technology.
I told her that I am doing my best to raise water prices. I also mentioned that rainwater "capture" is illegal in some places in the States. She had heard about Colorado but not about other states.
"Is it illegal to "divert" rainwater in other states?" She asked. I don't know. Readers! Do you know?
Bottom Line: This great idea will not get off the ground while water is too cheap to conserve.
