Graphene are carbon atoms arranged in a chicken wire pattern one atom thick — the thinnest material in the world. (What could be thinner than one atom?) Not only thin, but more than 100 times stronger than steel, transparent and flexible to boot. The graphene layer can be
manually peeled away from graphite (like in pencils) using regular adhesive tape. University of Manchester professors Andre Geim and Konstantin Novoselov just won the Noble Prize for their scotch tape experiments.
This vapor-deposited graphene appears to retain the qualities of manually peeled graphene. Electrons travel along the 2D surface of graphene at speeds nearing the speed of light -- making it ideal for circuitry.
"Graphite is a crumbly substance that resembles a layer cake of weakly bonded graphite sheets. When graphene is wrapped into rounded forms, fullerenes result. They include honeycombed cylinders know as carbon nanotubes and soccer-ball shaped molecules called buckyballs as well as various shapes that combine the two forms." From above.

We need to go back to nature in order to move forward. The Microbial Home is a proposal for an integrated cyclical ecosystem where each function’s output is another’s input. In this project the home has been viewed as a biological machine to filter, process and recycle what we conventionally think of as waste – sewage, effluent, garbage, waste water.
Greenpower Education Trust is an educational initiative established to offer schools an exciting way to introduce their students to green engineering. The young students design, build and race their own eco-race cars. By getting pupils hooked on engineering while they’re still young the project aims to inspire the next generation to develop solutions.

The Solar Roadways project is working to pave roads with solar panels that you can drive on. Their long range goal is to cover all concrete and asphalt surfaces that are exposed to the sun with Solar Road Panels. They plan to start off small: driveways, bike paths, patios, sidewalks, parking lots, playgrounds, etc. This is where they hope to learn lessons and perfect the system. Once the lessons have been learned and the bugs have all been resolved, they plan to move out onto public roads.
A Geminoid or twin-robot is designed to resemble a living person. It is controlled by an operator who through the use of advanced software can transfer facial movements and speech to the robot. For many years, robot technology has primarily been associated with factories and warehouses, but the days of thinking about robots as just 'tools' are over...
