Could our future cars be powered by methanol fuel cells, rather than gasoline engines or electric batteries? Perhaps. The National Institute of Science and Technology (NIST) is making the oil alternative more viable by developing a fast, simple way of producing platinum "nano-raspberries," which contain tiny clusters of nanoparticles. Each tiny piece of matter, measuring between 1 and 100 nanometers, acts as a catalyst inside fuel cells to help convert liquid methanol into electricity. The clusters are called nano-raspberries because of their fruit-like shape, and they're particularly effective due to their high surface area.
