Banking the Sun’s Energy

 Banking the Sun’s Energy

Using Sun’s Energy to Split Water Means Solar Power All Night

A U.S. scientist has developed a new way of powering fuel cells that could make it practical for home owners to store solar energy and produce electricity to run lights and appliances at night.

A new catalyst produces the oxygen and hydrogen that fuel cells use to generate electricity, while using far less energy than current methods.

Searching For ‘Sister Earths’?

Searching For ‘Sister Earths’? 

 A Jupiter-sized planet passes in front of its star in this artist’s impression of a transiting exoplanet.

Research presented at a recent astronomical conference is being hailed as ushering in a new era in the search for Earth-like planets by showing that they are more numerous than previously thought and that scientists can now analyze their atmospheres for elements that might be conducive to life.

Satellite Propelled By Solar Sails

Satellite Propelled By Solar Sails

 NanoSail-D

For the first time, NASA is preparing to send into orbit a small satellite that can be propelled by solar sails. When light particles from the sun strike the surface of the sail, the energy is transferred to it, providing a propulsive force that moves the satellite through space.

Solar-Powered TV By Sharp Unveiled

Solar-Powered TV By Sharp Unveiled 

 Sharp´s 26-inch low-power TV prototype paired with a solar module.

For the 1.6 billion people living in areas without utility-supplied electricity, Sharp has designed a TV that can get 100% of its power from the sun. The company plans to exhibit the 26-inch LCD prototype at the Hokkaido Toyako Summit, or G8 Summit, in Hokkaido, Japan, on July 7-9.

NASA Plans to Send Probe to the Sun

 NASA Plans to Send Probe to the Sun
Getting bored with looking at other planets, NASA now plans to probe the sun

For more than 400 years, astronomers have studied the sun from afar. Now NASA has decided to go there. ‘We are going to visit a living, breathing star for the first time,’ says program scientist Lika Guhathakurta of NASA Headquarters. “This is an unexplored region of the solar system and the possibilities for discovery are off the charts.”

Super Flare Captured by NASA

 Super Flare Captured by NASA

Much like a male peacock spreading his feathers, some stars have
to show a little flare to gain the attention of stars of the opposite sex

On April 25, 2008, NASA’s Swift satellite picked up a record-setting flare from a star known as EV Lacertae. This flare was thousands of times more powerful than the greatest observed solar flare. But because EV Lacertae is much farther from Earth than the sun, the flare did not appear as bright as a solar flare. Still, it was the brightest flare ever seen from a star other than the sun.
