Dr. Francesco Galembeck of Brazil's University of Campinas presented new research at the annual meeting of the American Chemical Society that, he claims, could lead to a new method of collecting renewable energy. According to his experiments, it is possible to generate an electrical charge by passing water vapor, potentially in the form of humid air, over metal particles. Theoretically, this means that with the right materials, it should be possible to literally pull electricity from the air, collecting it like an electric sponge. However, the charge collected in the experiments was exceedingly small -- not nearly enough to power much of anything.
