UNITED States President Barack Obama on Wednesday lauded Filipina engineer Aisa Mijeno, who invented lamps powered by saline solution, during a forum for the Asia-Pacific Economic Cooperation (Apec) Summit 2015 in Manila.

After delivering a speech, Obama led a forum during the Apec CEO Summit on Wednesday. Obama addressed questions to Jack Ma, the founder of Alibaba, a giant e-commerce firm, and Mijeno, an engineer and Greenpeace member who founded SALT Philippines.

The project provides lighting to areas without electricity with the creation of lamps that run on saline solution. The same solution is also used to charge mobile phones, Mijeno said during the forum.

A SALt lamp is an LED lamp powered by the galvanic reaction of an anode with saline water. The anode must be replaced every six months or so and the saline water daily. Sea water works. The SALt lamp was invented and is marketed by Aisa Mijeno, a Filipino inventor and entrepreneur.
