Artificial Leaf

A leaf is a biological mechanism designed to use the energy from sunlight to convert carbon dioxide and water into oxygen and sugar, providing the plant with energy in a form it can use. This chemical process is called photosynthesis. Researchers are working on artificial leaves that can use the energy from sunlight to split […]

Magnetic Solar Power

An optical battery that collects charge caused by light’s magnetic field may be usable as a power source. Solar power without solar cells: A hidden magnetic effect of light could make it possible – [] Light has electric and magnetic components. Until now, scientists thought the effects of the magnetic field were so weak that […]

Raman Optical Amplifiers

Early lasers “pumped” ruby rods with light from flash tubes creating a photon cascade that eventually produced a beam of coherent light. Recently, lasers have been developed that can produce a coherent beam of light from a silicon chip. Raman lasers are a particular type of silicon lasers. Simulations done on supercomputers have shown that […]

Artificial Photosynthesis

There is evidence to indicate that the earliest process of conventing sunlight into storable and usable energy (photosynthesis) began around 3.4 billion years ago on this planet. Over time, the bacteria that accomplished this changed the color range of light they absorbed from infrared into the visible spectrum and changed the waste output of their […]

Solar Impulse Aircraft

Maiden flight for Bertrand Piccard’s Solar Impulse aircraft – [] Solar Impulse, the solar airplane that Swiss adventurer Bertrand Piccard described in his captivating talk at TEDGlobal 2009, took off successfully this morning from Payerne airfield, in Western Switzerland, on its maiden flight. The aircraft (which has a wingspan of 63.40 meters but a weight […]
