Water Gen inked an agreement last week with India’s second largest solar company to produce purified water for remote villages in the country. Earlier, the company arranged with the Hanoi government to set up water generators in the Vietnamese capital.

“The government of Vietnam greatly esteems the technological developments in Israel, and I hope that the Israeli technology that we supply to Vietnam will significantly help to improve water conditions in the country,” Water Gen President Mikhael Mirilashvili said after the signing in Hanoi, according to a statement.

The memoranda of understanding are worth $150 million in total, according to Water Gen, which was founded in 2009 and creates technology that extracts water from the air for use by civilians and soldiers who do not have access to clean sources.

Harvard Law professor Alan Dershowitz demonstrated Water Gen’s technology on stage at the American Israel Public Affairs Committee’s annual policy conference in Washington, D.C., on March 26. He touted the device, which he said can produce 15-20 liters of drinkable water a day, as a weapon against worldwide water scarcity and the Boycott, Divestment and Sanctions movement against Israel.

“There is no weapon more powerful in the fight against BDS than for Israel to develop technologies that the world cannot live without,” he told the crowd. “You cannot boycott products that you can’t live without.”

About 1.2 billion people, nearly one-fifth of the world’s population, live in areas of water scarcity, according to the United Nations Department of Economic and Social Affairs. More than 75 million of India’s 1.25 billion people lack access to clean water, according to a report last year by Water Aid, a water and sanitation nonprofit. And Vietnam has struggled to provide its 95 million people with water because of contamination, poor infrastructure and heavy agricultural demand.

In India, Water Gen technology is to supply drinking water to remote villages with solar power from Vikar Solar. The Vietnam project is to generate tens of thousands of liters of water a day for the people of Hanoi. Water Gen also said it plans to build a factory to produce technology for sale in the region.
