Ocean Current Energy Conversion for Powering Sensors

Many organizations which conduct oceanographic research, such asĀ CSIRO, make use of electronic sensors for monitoring ocean conditions. At present, these sensors are powered by batteries, but this causes their deployment time to be limited by battery life. This limitation could potentially be overcome by harvesting energy from the environments surrounding the sensors. One such source …

Passive Irrigation Controller

The Food and Agriculture Organization of the United Nations calculates that agricultural irrigation consumes 70 percent of our global fresh water supply, they further express that 60 percent of that water is then wasted before it is used by crops. An important cause of water waste is the inappropriate scheduling of the irrigation periods leading to …

Pico-Scale Hydro Turbines

This project has been outsourced to WERL by a Toronto-based company that is currently developing innovative pico-scale hydro turbine systems, used for energy harvesting in both water disinfection and pressure regulation applications. In the disinfection system, a generator coupled to the pico-turbine provides power to an electrochemical cell appropriate for drinking water disinfection. The system is …

Smart and Sustainable Aeration Technology for Aquaculture

Collecting a water sample from an aquaculture pond Aquaculture is a major food source in many low and middle-income countries (LMICs). Improving water quality for aquaculture can increase yields, improve food security, and reduce antibiotic use. In the developed world, aeration is used to significantly improve water quality. However, aeration is the third largest cost …

Photovoltaic Reverse Osmosis Systems

Background For many remote off-grid communities, lack of access to clean water and reliable electricity are challenges for their economic development. Community owned and operated water systems powered by locally available renewable energy could be a step in overcoming these challenges. These systems need to be robust and cost effective in order to serve remote …
