NASA developing megawatt solar power arrays and will be used with solar electric propulsion

Posted by in categories: engineering, solar power, space, sustainability

.


NASA Glenn Research Center, GRC, currently has several programs to advance near-term photovoltaic array development. One project is to design, build, and test two 20 kW-sized deployable solar arrays, bringing them to technology readiness level (TRL) 5, and through analysis show that they should be extensible to 300 kW-class systems (150 kw per wing). These solar arrays are approximately 1500 square meters in total area which is about an order-of-magnitude larger than the 160 square meters solar array blankets on the International Space Station (ISS).

The ISS has the four (pair) sets of solar arrays that can generate 84 to 120 kilowatts of electricity. Each of the eight solar arrays is 112 feet long by 39 feet wide and weighs 2400 pounds. There were space missions involving astronauts working in space to install and deploy the ISS solar panels.

Record-Breaking Laser Hits 2,000 Trillion Watts

Posted by in categories: energy, solar power, sustainability

The most powerful laser beam ever created has been recently fired at Osaka University in Japan, where the Laser for Fast Ignition Experiments (LFEX) has been boosted to produce a beam with a peak power of 2,000 trillion watts – two petawatts – for an incredibly short duration, approximately a trillionth of a second or one picosecond.

Values this large are difficult to grasp, but we can think of it as a billion times more powerful than a typical stadium floodlight or as the overall power of all of the sun’s solar energy that falls on London. Imagine focusing all that solar power onto a surface as wide as a human hair for the duration of a trillionth of a second: that’s essentially the LFEX laser.

World’s first “aqueous solar flow battery” outperforms traditional lithium-iodine batteries

Posted by in categories: energy, solar power, sustainability

The scientists who last year revealed the world’s first solar battery that essentially combines a battery and solar cell, are now reporting its first significant performance milestone. Tested against traditional lithium-iodine batteries, the researchers are claiming energy savings of 20 percent.

Phosphorene could lead to ultrathin solar cells

Posted by in categories: energy, solar power, sustainability

Scientists at Australian National University (ANU) have used simple transparent sticky (aka “Scotch”) tape to create single-atom-thick layers of phosphorene from “black phosphorus,” a black crystalline form of phosphorus similar to graphite (which is used to create graphene).

“[Kyocera] announced an even larger project that will begin construction next year in the Kagoshima prefecture on land that had been designated for a golf course more than 30 years ago but subsequently abandoned. The 92-megawatt plant will include more than 340,000 solar modules and is expected to generate nearly 100,000 megawatt hours per year, or enough to power about 30,500 households when it goes operational in 2018.” Read more

Renewable energy boom will mean vastly cheaper electricity

Renewable energy boom will mean vastly cheaper electricity

Renewable energy, combined with prolific battery storage, will soon result in vastly cheaper electricity — and solar power that’s less expensive than what fossil fuel-based power plants can produce.

Additionally, solar power with lithium-ion and flow-battery storage systems will make the combination of renewable energy so inexpensive that it will surpass nuclear power and obviate the need for futuristic power sources such as fusion, according to Tesla CTO JB Straubel.
