We will need lighter structures to achieve better fuel economy, but what if the structure could also be part of the power system in a vehicle? That seems to be one of the possibilities in this fascinating breakthrough in material science. Graphenes are one-atom thick layers of carbon, and are the lightest, strongest structure yet achieved.
Not only is this material the strongest yet found, but the nano material has tremendous promise in electronics and solar PV devices. Consider that if it could be used to store and transmit current, a structure could be self-powering. To what extent could this be borne out in actual graphene structures?
