Transparent, flexible solar cells

Imagine a future in which solar cells are all around us — on windows and walls, cell phones, laptops, and more. A new flexible, transparent solar cell developed at MIT is bringing that future one step closer.

The device combines low-cost organic (carbon-containing) materials with electrodes of graphene, a flexible, transparent material made from inexpensive and abundant carbon sources.  The ability to use graphene instead of expensive brittle electrodes is making possible truly flexible, low-cost, transparent solar cells that can turn virtually any surface into a source of electric power.

Blended-wing airliner designs to slash fuel burn

Airbus is studying blended-wing airliner designs as a means to cut CO2 emissions by more than 20% and has already test flown a sub-scale model as part of its research efforts.

Blended-wing technology is of interest to the airframer because it is more efficient than standard tube-and-wing designs. The company is increasingly convinced that flying-wings are feasible because of the improvements in fly-by-wire and lightweight structural technology.

Removing heavy metals from water

Simultaneously removing heavy metals such as arsenic, chromium, cadmium and mercury from wastewater with very high efficiency now appears possible, thanks to the work of researchers at the Indian Institute of Technology (IIT) Bombay. The carbon-based nanostructure that the team fabricated shows 80-90% adsorption efficiency for all the four heavy metals studied.

Public autonomous vehicle – Tesla

Tesla’s designers envisioned a fun idea for autonomous vehicles that could be used publicly. It is a modular self-propelled vehicle that is not a one completed vehicle but a POD (application-specific upper module) mounted on a standardized platform. The idea is that the basic platform can be self-propelled in five stages, and the POD module is designed to be divided into the following categories: public transport, commercial transport, and personal transport.
