One of mankind’s biggest threats is the ever growing water shortage. One way to solve this is to clean seawater. Today more than 300 million people get their water from desalination plants around the world. Conventional desalination is however both expensive and energy demanding. Therefor i have developed a new way to desalinate seawater by utilizing water’s evaporative properties together with industrial waste heat, reducing the cost of cleaning 1000 liters of water to just 0.06€. Industries use 20% of freshwater around the globe and 60% in wealthy countries so self sustaining factories through my invention would be a huge step towards securing the water supply in the future. I am now leading a full-scale pilot project in Sweden capable of cleaning 40.000 liters/day with a local smeltery.
