Despite millions of dollars in losses by the likes of Zillow, iBuying’s failure doesn’t signal the end of tech-led disruption, just a fumbled beginning.
Perovskites are a family of materials that are currently the leading contender to potentially replace today’s silicon-based solar photovoltaics. They hold the promise of panels that are far thinner and lighter, that could be made with ultra-high throughput at room temperature instead of at hundreds of degrees, and that are cheaper and easier to transport and install. But bringing these materials from controlled laboratory experiments into a product that can be manufactured competitively has been a long struggle.
Manufacturing perovskite-based solar cells involves optimizing at least a dozen or so variables at once, even within one particular manufacturing approach among many possibilities. But a new system based on a novel approach to machine learning could speed up the development of optimized production methods and help make the next generation of solar power a reality.
The system, developed by researchers at MIT and Stanford University over the last few years, makes it possible to integrate data from prior experiments, and information based on personal observations by experienced workers, into the machine learning process. This makes the outcomes more accurate and has already led to the manufacturing of perovskite cells with an energy conversion efficiency of 18.5 percent, a competitive level for today’s market.

Spaceship Neptune will start carrying customers to the stratosphere in 2024, if all goes according to plan.
Space Perspective wants its passengers to fly in style.
The Florida-based company is working to send paying customers (as well as research payloads) to the stratosphere aboard its “Spaceship Neptune,” a pressurized capsule that will cruise high above Earth beneath an enormous balloon.
WASHINGTON – As Maxar Technologies’ satellites continue to collect images of Russia’s invasion of Ukraine, the company is working with customers so it can allocate more capacity to meet U.S. government needs, said Maxar’s CEO Daniel Jablonsky.
With four satellites in orbit, “a lot of times we don’t have a lot of spare capacity,” Jablonsky said in an interview last week at the Space Symposium in Colorado Springs.
“But we made accommodations with some of our other customers to be able to surge capacity for the U.S. and allies,” he said. The company also gets about 200 requests a day for imagery from news media organizations.
After restarting work on the project a few months ago, SpaceX appears to have gotten back up to speed and begun to make rapid progress on the construction of Starship’s first Florida launch pad and tower.
Located at NASA’s Kennedy Space Center (KSC) Launch Complex 39A facilities, SpaceX has intended to construct a Starship launch site there for several years. A serious attempt was made in late 2019 but SpaceX soon abandoned the effort and redirected its energy towards Starship prototyping and a much different launch pad design. Two years later, SpaceX’s second attempt shares only a little in common with the first. Both are to be located within the eastern half of Pad 39A’s shield-like footprint, although the specific location of the tower and launch mount has been modified. If this attempt comes to fruition, Starship’s first East Coast launch facilities will still sit just a few hundred feet away from the only SpaceX pad capable of launching Crew Dragon, Cargo Dragon, or Falcon Heavy.
Beyond those two characteristics, SpaceX’s second attempt is almost entirely different.
In the future, smart clothing might monitor our posture, communicate with smartphones and manage our body temperature. But first, scientists need to find a way to cost-effectively print intricate, flexible and durable circuits onto a variety of fabrics. Now, researchers reporting in ACS Applied Materials & Interfaces have developed a conductive 3D printing ink made of liquid metal droplets coated with alginate, a polymer derived from algae.
Conventional electronics are rigid and unable to withstand the twisting and stretching motions that clothing undergoes during typical daily activities. Because of their fluid nature and excellent conductivity, gallium-based liquid metals (LMs) are promising materials for flexible electronics. However, LMs don’t stick well to fabrics, and their large surface tension causes them to ball up during 3D printing, rather than form continuous circuits. Yong He and colleagues wanted to develop a new type of conductive ink that could be 3D printed directly onto clothing in complex patterns.
