Space Force X-37B mission to test power beaming

When a Boeing-built X-37B space plane is sent into orbit this month for the test program’s sixth flight, it will try out a technology that’s been more than a decade in the making: space-based solar power.

An experiment designed by the U.S. Naval Research Laboratory will transform solar power into a microwave beam, potentially for transmission to the ground. If such a power-beaming system could be perfected, concentrated microwave energy from space could conceivably be converted to electricity for far-flung military outposts.

Back in 2007, the Pentagon issued a report saying the U.S. military could be an “anchor tenant customer” for space-based power generation systems. That report piggybacked on a NASA study that was written a decade earlier, assessing the feasibility of wireless power transmission from space.

Heliogen claims solar power breakthrough

By Todd Bishop and Alan Boyle

solar energy tech company founded by serial entrepreneur and inventor Bill Gross — and backed by investors including Microsoft co-founder Bill Gates — says it has developed a way to create concentrated solar energy at temperatures hot enough to replace fossil fuels in industrial processes that contribute significantly to global carbon emissions.

It works by using cutting-edge computer vision technology to align a large array of mirrors to reflect sunlight to a precise target. The process creates immense heat, exceeding 1,000 degrees Celsius (1,832 Fahrenheit), that can replace traditional fuels such as coal, gas and oil in the production of materials such as cement, steel and petrochemicals.

The Los Angeles-based company, Heliogen, said this morning that it achieved the high-temperature milestone at its commercial facility in Lancaster, Calif.

It described the innovation as a “major step towards solving climate change” that could dramatically reduce greenhouse gas emissions from industrial processes. Such processes are thought to account for one-fifth of the world’s carbon emissions.

Solar-powered Odysseus drone will fly high in 2019

Aurora Flight Sciences, a pioneer in experimental flying vehicles that became a Boeing subsidiary last year, says its solar-powered, high-altitude, long-endurance Odysseus drone will take on its first flight in the spring of 2019.

Odysseus has been years in the making, part of an effort that dates back to the Daedalus Project in the 1980s, before Aurora was founded. MIT’s human-powered Daedalus plane set records in 1988 with a 72-mile flight over the Aegean Sea from Crete to Santorini. One of the leaders of that project was John Langford, who went on to become Aurora’s president and CEO.

“Aurora was founded by the idea that technology and innovation can provide powerful solutions to tough problems that affect all of humankind,” Langford said today in a news release. “Odysseus was an idea born out of Daedalus that is now a real solution to advancing the important research around climate change and other atmospheric chemistry problems.”

Aviation Week reported that Odysseus’ first flight has been scheduled to take place in Puerto Rico on April 23, 2019, the anniversary of Daedalus’ Aegean flight. The first battery-powered test craft is currently undergoing ground testing, and two more solar-powered aircraft are in the works, according to Aviation Week.

TV show reveals turmoil behind solar-powered flight

From the outside, it looked as if the Swiss-led Solar Impulse project smoothly soldiered through adversity as its solar-powered plane made a record-setting trip around the world in 2015 and 2016.

But the perspective was different when seen from the inside: The multimillion-dollar campaign nearly came crashing down when teammates debated whether to go ahead with a crucial Pacific crossing, even though the monitoring system for the autopilot wasn’t working right.

“The engineers were crying,” said Bertrand Piccard, the Swiss psychiatrist and adventurer who served as Solar Impulse’s co-founder, chairman and one of its pilots. “They were begging me to stop.”

The turmoil as well as the technology behind the globe-girdling, fuel-free odyssey are on full display in “The Impossible Flight,” a two-hour NOVA documentary premiering on PBS tonight.

Jeff Bezos touts Amazon’s solar campaign

Tesla CEO Elon Musk isn’t the only tech billionaire who’s high on solar power: Today,  Amazon CEO Jeff Bezos tweeted about the latest step in his company’s campaign to install rooftop solar systems on at least 50 of its fulfillment and sortation centers by 2020.

This week it was Baltimore’s turn.

The more than 6,000 panels installed on the roof of the fulfillment center in Baltimore should produce almost 2 megawatts of power, Amazon’s Tom Chandlee told WJZ.

“We’re expecting about a 30 percent savings in our overall energy bill, which is great, because we can pass that savings on to our customers,” Shan Byrne, the Baltimore fulfillment center’s general manager, was quoted as saying.
