Sun emits 2013’s first two X-class solar flares

The Sun has emitted its first two X-class solar flares of 2013, the first having happened on Sunday May 12, and the second yesterday. Both were relatively small in size, neither coming close to the record breaking X-flares of 2011 and 2012, yet were still powerful and resulted in spectacular images. Unlike the coronal mass ejection that happened back on April 12, these two were not directed towards Earth.

Graphene paint aims to solar-power future homes and electronics

Graphene paint aims to solar-power future homes and electronics

Scientists from the University of Manchester have discovered that by combining Graphene, a one-atom thick layer of graphite, with the transition metal dichalcogenides, a material that can react to light, they are able to create a product that can generate electricity from sunlight. They can form thin sheets of the product that can be placed on buildings to absorb sunlight and turn it into electricity.

Pilot to fly across US on solar-powered plane

Pilot to fly across US on solar-powered plane

A major milestone for solar technology is coming up, as one pilot will be taking on the task of flying from San Francisco to New York on a plane that's powered only by solar energy. Bertrand Piccard will be taking off in a plane that he and his design partner André Borschberg call Solar Impulse, which has been in the works for almost 10 years.

Space rock rips through ISS solar panel, gives hull a miss

Space rock rips through ISS solar panel, gives hull a miss

Space is a dangerous world. Debris is flying around everywhere, including small space rocks (read: bits of asteroid or meteoroid), which means that the International Space Station is constantly prone to getting hit by these small objects, and when you're traveling at 4.8 miles per second, even small objects can have a big impact. ISS Commander Chris Hadfield tweeted a photo of a hole in the one of the solar panels where a space rock ripped through.

World’s largest solar power plant opens in Abu Dhabi

World’s largest solar power plant opens in Abu Dhabi

The Middle East is known for their vast amounts of oil, and of course the money that comes from that oil. However, the region is also getting into renewable energy and alternative methods for providing electricity, most specifically the United Arab Emirates, which is now home to the world's largest solar power plant, located in Abu Dhabi.

New Apple patent suggests solar-powered iPhone on the way

New Apple patent suggests solar-powered iPhone on the way

Let's face it: battery life in smartphones is pretty awful, with only a few devices that are actually worthy of a battery-life crown. However, what if smartphones were powered by solar cells? That would basically change how we use devices, and we would essentially not have to worry about battery life anymore. A new patent from Apple may very well point to a possible solar-powered iPhone in the future.

Scientists develop first all-carbon solar cell

Scientists develop first all-carbon solar cell

Scientists at Stanford University have built the world's first all-carbon solar cell. Because carbon offers a combination of low cost and high performance, it is a viable alternative to current photovoltaic materials, which are expensive. This new solar cell is made from materials such as carbon nanotubes and "buckyballs".

Scientists warn massive solar flare could harm power grid and satellites

Scientists warn massive solar flare could harm power grid and satellites

A group of scientists have put the world on alert that a massive solar flare could happen within the next two years that could harm power grids, communications, and satellites around the world. The scientists say that the risk of a massive flare that could harm systems on the earth increase as the sun reaches the peak of its 10-year activity cycle. The scientists say "governments are taking it very seriously."

Walmart announces 100th solar installation in California

Walmart announces 100th solar installation in California

You only have to set foot in most Walmart stores to know that the company wants to be green. For instance, in my local store, there are hordes of skylights all around the building in the ceiling and lights in the store turn off and on depending on how much light is coming through those skylights from the outside. That means you to be walking around and suddenly some of the lights turn off making the interior darker. I assume most Walmart locations use similar systems.
