Sylvia has posted my drawing of bucket siphons, air pumps and tea makers at http://aquaponicscommunity.com/page/glenn-martinez-aquaponics-manual. Enjoy. Some of the designs are "patent pending" but only for manufacturing rights. Individuals, non-protits and educational are free to make their own devices for use. It just when you cross the line to manufacturing that we need an agreement. Enjoy, these devices have made solar power practical.
