It is June 2022, and a flying machine that looks like a cross between a prehistoric beast and a spaceship is about to take off. Named the Zephyr S, it has long spindly wings the length of an airliner’s. Together with its small, thin body and head, these make it resemble a pterodactyl. Its shimmering tinfoil-like solar panels and lightweight skeletal frame are more like something you’d see on a craft meant for space.
Its mission for the US Army is a secret, but clearly on its manufacturer’s mind is the desire to shatter a few records, particularly that for the longest flight duration for any type of airplane, which has stood for 63 years. In 1959 two men flew a four-seat Cessna light aircraft for 64 days, 22 hours and 19 minutes, refuelling in-flight from a truck.
British aviation pioneer Chris Kelleher designed the first Zephyr in 2002. His vision was of an uncrewed aircraft capable of “eternal flight” in the stratosphere. He foresaw that solar power and lightweight materials would lead to aircraft capable of staying aloft for months, or even years. The Zephyr S is the first production model.
The stratosphere is the second layer of our atmosphere. It begins around 33,000ft (10,000m) and ends at around 160,000ft (48,800m). If an aircraft can fly above 50,000ft (15,150m), it can fly above the turbulent weather that we experience closer to the ground, in the troposphere. The problem is that that high the air is very thin, making flying – and breathing – a challenge.

COPENHAGEN, June 14 (Reuters) — Swedish electric self-driving truck company Einride expects to reduce CO2 emissions in Norway by 2,100 tonnes over the coming three years as it partners up with Scandinavia’s leading postal service, PostNord, the company said on Wednesday.
Norway has the world’s highest number of electric vehicles per head of population and aims for all heavy vehicles to be zero-emission by 2040, potentially cutting CO2 emissions by 4.4 million tonnes or nearly 9% of the country’s annual emissions.
“Given Norway’s pioneering work in electrifying passenger vehicles, it’s only logical that they should take a leading role in the electrification of heavy-duty freight as well,” Einride CEO Robert Falck said.

The transition to renewable energy, critical for the world’s future, is limited today by energy storage and transmission challenges. Beaming solar power from space is an elegant solution that […] promises a remarkable payoff for humanity: a world powered by uninterruptible renewable energy.
The California Institute of Technology reports the first successful beaming of solar energy from space down to a receiver on the ground, via the MAPLE instrument on its SSPD-1 spacecraft.
