Record-breaking aviators Brian Jones and Bertrand Piccard hope to harness the Sun's power to fly round the world. The pair gained worldwide recognition in 1999 when they became the first to circumnavigate the globe in a balloon. Now they plan to repeat the journey in a solar-powered aeroplane which will have to use batteries to fly at night.

The spacecraft will investigate the colossal explosions in the Sun's atmosphere known as solar flares. These dramatic events release energy equivalent to tens of millions of hydrogen bombs in just a few minutes.

Scientists have been able to extract precious information from the smashed remains of the Genesis space capsule. The capsule, carrying captured particles blown off the Sun, crashed into the Utah desert in 2004, after its parachute failed. Less than half the samples are useable, but researchers have been working hard to recover what they can.

Scientists have retrieved the damaged science canister from the Genesis mission and taken it to a clean room at the US Army base where it crashed. A team of specialists plucked pieces of dirt and mud that had lodged in the canister after it smashed at high speed into the Utah desert. The Nasa Genesis team says it will begin examining the contents of the capsule later on Thursday. Scientists are hopeful they can recover some of its solar...

The Genesis probe, which left Earth in 2001 to gather particles blown off the Sun, returns its cargo on Wednesday. It will eject a capsule that will enter Earth's atmosphere at 40,000km/h before slowing, with the help of a parachute, to fall over the Utah desert. Hollywood stunt pilots are waiting to snatch the parachute in midair to prevent the capsule hitting the ground. Scientists hope the particles of solar wind can tell them...

... solar films on buildings with enough left over to feed a surplus back into the grid. Tomáš J. Fülöpp 20071113: I expected something very similar to this. I thought bricks (or other construction materials) could be mass made with photovoltaic capabilities. they'd be modular, so large walls would produce more energy. and they could be cheap, because even low efficiency technology would be enough to provide enough...

In a revolutionary leap that could transform solar power from a marginal, boutique alternative into a mainstream energy source, MIT researchers have overcome a major barrier to large-scale solar power: storing energy for use when the sun doesn't shine.
