Bacteria Colony Reacts with Seawater and Mud to Produce Electricity

Until now, scientists haven't been able to provide the reasons of just how bacteria generate electric networks that serve as long distance communication systems. They have known just that it can produce electric energy when mixed with seawater and mud, leading to the development of microbial fuel cells.

Hertz Car Rental Service Using Electric Nissan LEAF in Their Future Offer

Hertz, a worldwide car hire company, plans to buy electric cars and make them available for renting in Europe and the U.S. within the next two years. Teaming up with Nissan, they will start their electric car hire service with LEAF, Nissan's first electric car available to the public.

IBM's Efficient Thin Film Solar Cell Made of Cheap Materials

They managed to increase the efficiency with almost 40% of their solar cells, from 6,7 percent to 9,6 percent. To reduce even more the costs, these solar cells are build with an inexpensive ink-based process.

New Flexible Silicon Solar Cells Use 99 % Less Material With Same Efficiency

CalTech researchers discovered a new way to make silicon solar cells that not only use 1 percent of the material needed to make conventional cells, but which are also thin and flexible, making them suitable for a much larger palette of uses in all kinds of applications. And let's not mention the fact that the price will be considerably lower, respectively.

Porsche 911 GT3 R Hybrid Using 160hp Flywheel for Its Electric Motors

Porsche has already been recognized all over the world as building quality performance cars, despite their "heavy" price and big engines. It looks like now Porsche is trying to green itself out and use an innovative hybrid technology based on a flywheel, installed in a racing car.

DNA-Like Metal Organic Frameworks to Store Carbon Dioxide Efficiently

UCLA scientists, led by professor Omar M. Yaghi have created three-dimensional, synthetic DNA-like crystals which are capable of storing carbon dioxide: We have taken organic and inorganic units and combined them into a synthetic crystal which codes information in a DNA-like manner.

Semprius's Micrometric Solar Cells Efficient in Concentrated Photovoltaic Systems

Concentrated photovoltaic systems are usually more effective than regular, flat ones, because a lens focuses the sunlight on a smaller surface of some efficient and more expensive solar cells 500 times stronger than the cells would receive in regular operation. Heat is mostly a problem with concentrated PV systems, since it has to be efficiently dissipated through complex and expensive cooling technique.

Hell's Gate in Turkmenistan: Burning Precious Energy for Nothing Since 1971

This hole (initially a gas-filled cave) has been named "Hell's Gate", for obvious reasons. It was discovered when some geologists have been searching for natural gas, in Turkmenistan's Karakum desert, in Darvasa. The ground beneath the drilling rig collapsed, leaving a large hole with a diameter of about 50-100 meters.

World's Smallest Solar Powered Sensor Invented by University of Michigan Researchers

University of Michigan engineers developed the smallest solar powered sensor system, having only 9 cubic millimeters, that can harvest energy from ambient light to operate.

Scientists Develop a Quantum-Dot Process to Split Water and Generate Hydrogen

Fuel cells can be used in various applications such as spacecraft, remote weather stations, large parks, rural locations, military applications and automotive industry. Fuel cells have hydrogen as the base element for their power.
