Value of Distributed Energy Resources Largely Depends on Three Things: Location, Location, Location

As solar panels cover more rooftops, and buildings with load controls and storage provide more grid services, understanding the value of distributed energy resources (DERs) is increasingly important. Yet few utilities and states consider their value at specific points on the electric system in planning, procurement, and design of DER programs and rates.

A new Berkeley Lab report, Locational Value of Distributed Energy Resources, explores economic valuation and regulatory considerations for assessing locational value. A free webinar on the report will be held on March 9, 2021, at noon Pacific/3 p.m. Eastern. Register

Nanowire could provide a stable, easy-to-make superconducting transistor

Superconductors — materials that conduct electricity without resistance — are remarkable. They provide a macroscopic glimpse into quantum phenomena, which are usually observable only at the atomic level. Beyond their physical peculiarity, superconductors are also useful. They’re found in medical imaging, quantum computers, and cameras used with telescopes.

But superconducting devices can be finicky. Often, they’re expensive to manufacture and prone to err from environmental noise. That could change, thanks to research from Karl Berggren’s group in the Department of Electrical Engineering and Computer Science.

MIT researchers are developing a superconducting nanowire, which could enable more efficient superconducting electronics. Image

Fabricating fully functional drones | Technology Org

From Star Trek’s replicators to Richie Rich’s wishing machine, popular culture has a long history of parading flashy machines that can instantly output any item to a user’s delight.

While 3D printers have now made it possible to produce a range of objects that include product models, jewellery, and novelty toys, we still lack the ability to fabricate more complex devices that are essentially ready-to-go right out of the printer.

A group from MIT’s Computer Science and Artificial Intelligence Laboratory (CSAIL) recently developed a new system to print functional, custom-made devices and robots, without human intervention. Their single system uses

International study shows asteroids as past, possible future water source

A Florida State University geochemist was part of an international team that published startling evidence that a type of meteorite — fragments of ancient asteroids that land on Earth — shows signs it contained liquid water no more than a million years ago.

Scientists have long hypothesized meteorites delivered water from asteroids to Earth in the solar system’s infancy. But it was unclear if asteroids, bodies that orbit the sun, still held water in the form of ice or if that was lost in space. The team’s findings, published in the journal Science, suggest the asteroids these meteorites came

What rules govern the structure of membraneless organelles?

In cells, numerous important biochemical functions take place within spherical chambers made from proteins and RNA.

These compartments are akin to specialized rooms inside a house, but their architecture is radically different: They don’t have walls. Instead, they take the form of liquid droplets that don’t have a membrane, forming spontaneously, similar to oil droplets in water. Sometimes, the droplets are found alone. Other times, one droplet can be found nested inside of another. And these varying assemblies can regulate the functions the droplets perform.

Scientists created the first practical bioresorbable 3D-printed airway stent

Various injuries and diseases cause the main bronchi or the trachea to narrow, which then makes breathing very difficult and people may suffer from the lack of oxygen. Surgical methods can bring quick relief, but metal or silicone stents usually require other surgeries. New study showed that 3D printable bioresorbable airway stents could be the answer in these situations.

These stents are 3D printed using a new light-activated resin. They disappear in the body in 6-7 weeks. Image credit: ETH Zurich

Metal airway stents have to be surgically removed, which is another invasive surgery, while silicone ones sometimes move away
