10 International Product Review Israel ROOTS Ltd. Irrigation by Condensation (IBC) The next Ag Tech revolution ROOTSSAT.COM (listed on Australian Stock Exchange - ROO) Ϳ hnologies of the Month" ROOTS L t d . ’ s I r r i g a t i o n b y Condensation (IBC) system works by chilling water in an insulated water tank to a temperature below the dew point and pumping the chilled water, in a closed cycle, through a grid of blind (unperforated) pipes installed vertically or horizontally on ground surface. Moisture from the air and from the soil condenses on the pipe's external surface and flows to the plants roots by gravity. Proof of Concept has been achieved on five crops: Spinach, Tomatoes, Lettuce, Wheat and Cucumbers. This is a game changing, disruptive technology to facilitate plant's growing cycles for human and animal consumption. The water is chilled by an electric, solar or alternative power source. Sensors for remote reading of key parameters (dew point, water temperature, ambient temperature, etc.) are installed and computer software is in development to automatically control temperatures and other operating parameters.

An Innovative Way to Protect Water Conveyance Pipelines It is well known to all those involved in liquid conveyance that the presence of air in a pipeline transmission system must be treated. Controlling the intake and discharge of air into the line is a critical part of overall planning. A.R.I., the world leader in the field, has learned over the years that it is not enough just to admit and expel air, but tomanage the rate of intake and the rate of discharge independently, according to the needs of the system. By the use of a dedicated accessory, you can control these rates and provide optimal protection for the transmission line. The control of the rate and volume of air that is discharged is carried out by the throttling back and the slowing closure of the air valve which creates an "air cushion", prevents "slamming" (too fast closure of the air valve) and reduces local surge in the air valve riser.
