Nissan's Leaf - All-Electric Zero Emmission 5 Passenger Car

\

This new video reveals a few addition details about the Leaf. According to the company, the Leaf will feature LED powered headlights and taillights. This design and use of LED technology will reduce the load on the battery system as LEDs operate with about 1/10 the electricity of conventional bulbs.

Additional design elements focus on aerodynamics of the vehicle. According to Nissan, aerodynamics were a main focus throughout the design process. For instance, the flat floor was designed to reduce wind resistance and the unique headlights were designed to reduce wind noise and resistance by splitting and redirecting airflow away from the outside mirrors.

Wave energy generator pumps power to Scotland

Wave energy got a boost with the connection of the Oyster hydro-electric device to the electricity grid in Scotland last Friday.

Aquamarine Power activated the connection of the Oyster in the waters off Orkney, marking one of the few ocean power devices to be producing electricity.

The device is a hydraulic pump operated by a "hinged flap," where a large metal piece moves back and forth from the motion of the waves. The movement moves a hydraulic piston that pumps water underground to a hydro-electric turbine that drives a generator to make electricity.

The peak power output of the Oyster 1 is about two megawatts, depending on the location.

How 16 ships create as much pollution as all the cars in the world

"Last week it was revealed that 54 oil tankers are anchored off the coast of Britain, refusing to unload their fuel until prices have risen.

But that is not the only scandal in the shipping world. Today award-winning science writer Fred Pearce – environmental consultant to New Scientist and author of Confessions Of An Eco Sinner – reveals that the super-ships that keep the West in everything from Christmas gifts to computers pump out killer chemicals linked to thousands of deaths because of the filthy fuel they use.

Both international shipping and aviation are exempt from the Kyoto Protocol rules on cutting carbon emissions. But green pressure is having its effect on airlines. Ahead of next month’s Copenhagen climate talks, airlines have promised to cut emissions by 50 per cent by 2050.

Bioengineers succeed in producing plastic without the use of fossil fuels

"A team of pioneering South Korean scientists have succeeded in producing the polymers used for everyday plastics through bioengineering, rather than through the use of fossil fuel based chemicals. This groundbreaking research, which may now allow for the production of environmentally conscious plastics, is published in two papers in the journal Biotechnology and Bioengineering to mark the journal's 50th anniversary."
