Aisa Mijeno

Filipino engineer who invented sustainable saltwater-powered lamps for off-grid communities

Aisa Mijeno co-founded SALT (Sustainable Alternative Lighting), creating the world's first electro-chemical lamp powered by saltwater. This innovation emerged from her experience living with the Butbut tribe in Kalinga province, where she witnessed energy poverty firsthand.

The SALt lamp's MIT-tested technology works through:

  • Galvanic cell reactions using saline solution
  • 8 hours of light from 1 glass of seawater
  • Zero combustion emissions

Mijeno's invention has:

  1. Provided light to 15,000+ Philippine households
  2. Reduced kerosene-related fires in coastal villages
  3. Inspired ocean energy research at 7 Asian universities

Her TED Talk redefined renewable energy solutions for archipelagic nations, earning recognition from the UN Climate Change Conference.
