Earlier this year, it has almost been said that cow burps are the root of all evil regarding global warming, the emissions of methane gases and, overall, an enemy of our humble existence on this planet. Well, recent "discoveries" reveal the fact that a well-managed cow could actually help reduce methane emissions.
Sharp Corporation has recently announced a breakthrough technology with which it has achieved the world's highest solar cell conversion efficiency of 35.8%.The best feature of this triple-junction compound solar cell is that it uses photo-absorption layers made from compounds consisting of two or more elements such as indium and gallium.
A very simplified synthetic model battery has been developed by scientists from the Yale University and the National Institute of Standards and Technology. The cells are based on organic substances and can generate power for minuscule devices.
A spinoff from the Swedish military and aircraft design firm Saab, Minesto has developed a new concept of underwater wave energy using a simple 7 ton kite turbine design. Exactly like a kite in the wind, the Deep Green underwater turbine collects and stores the power of the ocean.
The market is in a continuously search for a battery pack that should be able to power portable electronic devices for a longer period of time and with shorter charging times. Toshibas' Dynario Charger is the perfect solution for the moment.
The chemists from the Idaho National Laboratory and Idaho State University may have found the gold mine of solar energy efficiency. They invented the manufacturing of a highly precise and uniform nanopaticle that improves solar cells and further spurs the growing nanotech revolution.
Dennis Weaver (1924-2006), a retired actor, environmentalist, humanitarian, has built a house whose walls are made of nothing but rubber tires and cans. It is very energy-efficient, as he himself discovered, powered mostly by solar panels and renewable energy.
Dye-sensitized solar cells, or Grätzel cells, have been invented by Michael Grätzel in 1991. Grätzel is a chemistry professor at the École Polytechnique Fédérale de Lausanne in Switzerland, and since now they didn't have any commercial purpose, being developed...
A company called Renew Blue, Inc. will use wave power to run a desalination plant in Freeport, Texas. The resulted water will be finally put into corn-based biodegradable plastic bottles. The SEADOG power system is made from a buoy which puts in motion a piston mechanism that rotates a water wheel to generate electricity.
A team of scientists from the University of Rochester has a tough mission creating a hydrogen fuel cell that not only burns cleanly but the fuel itself has to be created from clean sources. They have developed a process that uses artificial photosynthesis and nanotubes to finalize this project.
