Solar Power

Commercial spaceflight is booming and looks to go into full-on kaboom stage in the near future, sparking the need for an ever-increasing supply of solar panels. To fill this need, Dcubed is developing its ARAQYS system to manufacture arrays in orbit.

To keep solar power stations from getting lazy, Sandia National Laboratories scientist John Sandusky is looking to give heliostat mirrors a side hustle. At the National Solar Thermal Test Facility he's experimenting with getting them to hunt for asteroids at night.

The Dutch love to cycle. So much so that there are more than 35,000 km of cycle paths snaking through the Netherlands. Two of those bike routes have now been topped with photovoltaic cells to produce renewable energy while they face skyward.

Researchers have created a floating, solar-powered device that converts contaminated water or seawater into clean hydrogen fuel and drinking water. Because it works with any open water source, it could be used in resource-limited or remote places.

According to a study by Astrostrom for ESA, future Moon bases could be powered by a giant space butterfly called the Greater Earth Lunar Power Station (GEO-LPS) covered with solar panels made from lunar materials beaming microwaves to the surface.

Solar farms and agriculture are competing for land. UCLA Scientists have now tested a way to combine the two by placing semi-transparent solar cells on the glass roofs of greenhouses, finding that they actually improve the growth of plants inside.

Ordinarily, water is used to clean off the layer of dust that continuously accumulates on solar panels. In arid regions, however, doing so can be challenging. A new system addresses this problem, by substituting electrostatic repulsion for water.

While solar farms are a source of green energy, many people don't like the fact that they occupy land which could be otherwise utilized. A new project is exploring an alternative, by placing solar panels over canals that will benefit from the shade.

Astronauts aboard the International Space Station have undertaken three spacewalks over a 10-day period in order to install and power up a new set of roll-out solar arrays to the exterior hull of the orbital outpost.

When the US Air Force's X-37B autonomous spaceplane launched into orbit for the sixth time this week, it carried an experiment to explore the potential for beaming solar energy from space to Earth using microwaves.

Scientists at Berkeley Lab have developed a sort of “solar umbrella” which could radically reduce the amount of land needed for industrial evaporation ponds.

The search is very much on for new water desalination technologies that can get the job done more efficiently. Scientists in Melbourne have put forward one rather promising solution, developing a new kind of system that heats up and purifies water using only the power of the Sun.​
