Knowing when you've got a leak or an unusual water flow in your pipes is a big concern for water and utility companies, so smart water sensors and monitoring devices are needed to stay on top of those situations.
Powering all of those monitors takes electricity, and for the ones in remote locations, batteries are necessary, which only last for a couple of years. But an innovation in microgenerators from an Israeli startup may be able to power those remote monitoring systems with energy generated from the water in the pipes themselves.
"HydroSpin has developed a set of unique in-pipe generators that generate electricity from the flow of water inside distribution pipes. The HydroSpin generator creates enough power to support low-energy devices throughout the water network; such as sensors, probes and transmission devices (GPRS)." - HydroSpin
Hydrospin, based in northern Israel, developed their generator system based on two years of research into solutions for eliminating the need for batteries in monitoring systems. Locations with no access to electricity can still have sensor deployed there, without any fear of solar panels or other remote power generators being damaged or stolen.
“The batteries are at the source of two problems: First, the used battery cannot be recycled, so it’s not environment-friendly. Second, replacing batteries is expensive and causes disturbance in the water networks during the replacement." - Gabby Czertok, CEO of HydroSpin
According to the company, their system is able to generate electricity without any water loss or disturbing the flow inside the pipes, and any necessary maintenance can be done via a remote control - without any physical human intervention.
