Tank mixer
SolarBee has announced that its GridBee GS-12 potable tank mixer is now available with a 120v motor, as well as the original 48v motor. The 120v motor option eliminates the voltage converter box and reduces the total project cost to under $10,000 in most cases. Developed from the same long-distance circulation technology as the solar-powered models, they help solve water-quality problems by creating a near-laminar flow that can prevent and control stagnation and thermal stratification in potable-water storage tanks.

Stormwater holding tank
Festo has developed a stormwater holding tank solution that is energy self-sufficient. Solar and wind energy are used to generate and store electricity. The energy is used to power a control unit and operate pneumatic actuators. If the power supply from one of the energy sources fails, a built-in emergency function ensures that the gate valves can continue to be operated several more times until a repair or replacement has been carried out. Using a Festo GSM modem, the entire system can be controlled and monitored from a remote control center.
