🚀 Astronauts on the Artemis II mission will reach several historic milestones today, journeying farther than anyone has from Earth as they make their lunar flyby and lay eyes on the far side of the moon.
🇬🇧 Following a historic vote, U.K. women who have been convicted, and in some cases jailed, over illegal abortions are set to be pardoned.
Scientists just achieved an ‘impossible’ solar energy efficiency breakthrough
Researchers in Japan developed a new material that allows solar cells to generate an amount of solar energy previously thought impossible. They did it with a “spin-flip” emitter that can harvest solar energy typically lost as heat.
It’s the latest in a string of recent solar technology breakthroughs that will only make the renewable energy industry more efficient and cost-effective.
Why is this good news? Prior to this breakthrough, solar cells had an energy conversion efficiency limit of 130%, and could only harvest energy from about one-third of available sunlight. The discovery could pave the way for ultra-efficient solar panels, and even further reduce global dependence on oil and gas for energy production.
The price of lithium-ion batteries has fallen 99% in the last three decades
Battery prices have dropped a lot over time — more than 99% since the early 1990s. Lithium-ion battery cells that once cost around $9,200 per kilowatt-hour now cost roughly $78, making technologies like electric vehicles far more affordable to the average consumer.
The price drop is not due to one breakthrough, but rather thousands of incremental improvements in the battery’s chemistry, manufacturing, and supply chain. As production has scaled up, engineers and firms have discovered more efficient ways to design and build batteries, leading to continuous cost reductions over time.
At the same time, batteries have also gotten better. They can store more energy in a smaller space than before, which makes devices last longer and cars go farther on a single charge.
