Producing electricity at estuaries using light and osmosis

Experimental scientists reproduced the real-world conditions that occur where rivers meet the sea (pH a. salt concentration) and showed that, by shining light on a system comprising salt, water and a membrane three atoms thick, it was possible to optimize electricity production. Credit: EPFL

Ions passing through a nanopore

Reproducing the conditions that occur at estuaries, EPFL scientists shined light on a system combining water, salt and a membrane just three atoms thick to generate more electricity. Credit: EPFL

Harnessing the power of sunlight

Under the effect of light, the system produces twice as much power as it does in the dark. Credit: EPFL
