Energy recovery for sustainability
Electricity is one of the principal operating costs for irrigation districts. Moving water from the source of supply to the fields to be irrigated requires constant energy. The design of irrigation canals often provide for drops that are used to dissipate increments of excess energy as water accelerates along the canal due to elevation drops in the terrain. Generating electricity at these drops can provide an excellent, and generally unused, opportunity to recover some of the excess gravitational kinetic energy in moving water. Until now technology has not been available to economically recover ...
