ethys Solar Desalination (TSD) is an Israeli startup founded in 2014, specializing in solar-powered desalination technology. Their innovative approach utilizes solar energy directly to desalinate and treat water, offering a scalable and environmentally friendly alternative to traditional methods. This technology is particularly beneficial for off-grid locations, including remote villages, desert resorts, and disaster-stricken areas.

The core of TSD's system is a modular design that can process up to 10,000 cubic meters of water per day. By harnessing solar heat to evaporate water and then condensing the purified vapor, the system significantly reduces energy consumption—by more than 90% compared to conventional desalination techniques. This reduction leads to lower operational and maintenance costs, making the technology both cost-effective and sustainable
