I am aware that a lot of work is going on regarding graphene material. This material has good characteristics, it is rechargeable and consumes less energy.
Graphene may produce the kind of change that semiconductors produced in the late 50s. A global technological revolution took place as a result of transistors and the multiplicty of technologies and industries that burgeoned as a result.
The resulting transistor-based technological artefacts changed our lives and continue to do so. It seems that the graphene revolution has already started. With the US and the EU calling it a "strategic mineral" and China holding 70% of the world supply. The future of graphene is set to make yet further barrier-breaking records in many fields I guess, including the computer field.
