Nearly any material can be used to turn the energy in air humidity into electricity, scientists found in a discovery that could lead to continuously producing clean energy with little pollution.

The research, published in a paper in Advanced Materials, builds on 2020 work that first showed energy could be pulled from the moisture in the air using material harvested from bacteria. The new study shows nearly any material can be used, like wood or silicon, as long as it can be smashed into small particles and remade with microscopic pores. But there are many questions about how to scale the product.
