Rainwater Harvesting, Personalized

We were flipping through a twelve year old book on the Japanese art of Chindogu, invented by Kenji Kawakami and published as 101 Un-Useless Japanese Inventions. Rule Number One is "A chindogu cannot be for real use. Inventions claiming to be Chindogu must, from a practical point of view, be completely useless."

However with the passage of time what once seemed useless can become quite sensible, like the Personal Rain Saver. As the author said: "No one has any illusions about the value of water as a natural resource. Yet all of us watch hundreds of gallons washing off our umbrellas into the gutters every year. With the Personal Rain Saver, you not only stay dry, you can collect your own share of natural precipitation in a shoulder-harnessed tank."
