This could be a new source of clean energy along the coastlines of the world.
The leader of the project, Jean-Pierre Leburton, a professor of electrical & computer engineering, said that their design was still a concept at this stage, but it was very versatile and showed great potential for energy applications. He said that they started with an academic question – ‘Can a nanoscale solid-state device extract energy from ionic flow?’ – but their design surprised them in many ways.
The main author of the study, Mingye Xiong, a graduate student in Leburton’s group, said that they discovered two unexpected behaviors when they simulated their device. He said that they found that the device worked equally well whether the electric forces were attractive or repulsive. He also said that both positive and negative ions contributed to drag.
The researchers also found that these effects did not depend on the specific shape of the channel or the choice of materials, as long as the channel was narrow enough to ensure closeness between the ions and the charges.
