The scarcity of fresh water resources and the growing need for additional water supplies has become a crucial issue in arid regions of the world. Water covers at least 70% of the Earth, but 97% of it is too salty to drink. Fresh water is needed not only for human consumption, but also for crop irrigation. This problem will only become more exasperated as the population continues to grow and the current fresh water supply becomes depleted.
Desalination is the process of removing salt and other minerals from saline water and utilizes Earth’s abundant supply of readily available saline water by converting it to useable water. Only about 15 billion gallons, which equates to less than 1% of the fresh water consumed around the globe per day, is desalinated water. There are currently many available technologies for desalination, including distillation, membrane processes, crystallization, and chemical processes. The main cost considerations of conversion plants include cost of energy, cost of operation, and cost of maintenance.
Black Sun Planetary Solutions aims to lower the overall cost of desalination by providing an innovative design solution that involves cost-efficient materials, low-cost energy source, and reduced operational and maintenance costs. The design does not require heating sources or expensive permeable membranes that also demand high maintenance and operational costs. Instead, BSPS utilizes the fundamentals of boiling point and pressure relationship of water to craft a unique design that’s accessible and affordable to all. BSPS is looking forward to construct and test its design and, in the future, interface solar power heating with desalination to improve cost-efficiency.
