The clean car story gets better and better. Current electric car still need batteries that require not so nice chemicals and time for recharging. The hydrogen fuel cell car is the next step with the fuel cell powering the electric engine. The first such cars will enter the roads of Japan and California next year. The fuel cell can be refueled at hydrogen gas stations that are being built. Next step: We don’t need these hydrogen stations anymore because the hydrogen can be filtered straight out of the air while a car is driving. Science fiction? Hydrogen is the most abundant substance in the atmosphere. Scientists have discovered a way to use graphene—a substance isolated in 2004 that is stronger than steal and only an atom thick—to strip the electron off of a hydrogen atom, creating the clean fuel for the fuel cell. You could then drive without ever having to fuel up.
