The Green Optimistic

One thing is to be noted here: one gram of carbon made from corncobs has its molecular internal surface equal to a football field, plus it has been proved that boron doping will further increase this capacity in great amounts.

Scientists from the University of Illinois at Urbana-Champaign and Northwestern University invented a silicon solar cell. The interesting fact is that it’s flexible and it can be printed on a curved surface or a fabric. Although solar paint has been produced, there are a few situations where you’d rather use more solid solar cells (like porous surfaces, where paint cannot be applied well).

MIT researchers discovered the solution to a problem put 100 years ago by Ludwig Prandtl. It refers to the situation when, for example, a car accelerates up and down a hill, then slows to follow a turn, and the airflow around it cannot keep up and separates from it. This aerodynamic phenomena creates an additional drag, slowing the car, and forcing you to push harder on the pedal, consuming more gas.

Professor Rongija Tao, from Temple University, invented a device that, applied to the vehicle’s fuel line, near the injectors, creates an electric field that reduces the fuel’s viscosity, so that smaller droplets are injected into the engine, leading to better combustion and increased fuel efficiency as much as 20%.

It seems like Einstein did his best not only in quantum physics, but also in classic, immediately-helpful science. Back in the 1930’s, helped by his friend Leo Szilard, he invented a refrigerator that used no electricity at all. Scientists from Oxford are struggling to revive his invention today.

This is great news. William Yuan, a 12 year-old from Beaverton, Oregon, has made an innovation in the 3D solar cells production that could provide 500 times more light absorption than commercially-available solar cells and nine times more than cutting-edge 3D solar cells. It may sound weird, but, at his age, he studied nanotechnology.

Engineers and scientists from the University of Texas at Austin, led by Rod Ruoff, a mechanical engineering professor and physical chemist, have created a one-atom thick layer of carbon, called “graphene”, and they put it to use in electrical storage systems, such as ultracapacitors, a viable way to clean and efficient energy storage.

It’s not breaking news anymore, but some scientists from the University of Massachusetts, Boston, and others, led by Stuart Licht, discovered a battery that could kick out fossil fuels at the chapter of energy storage capacity.
