A team at the US Department of Energy’s Oak Ridge National Laboratory has developed a utility-scale solar and storage project that can provide power to both AC and DC high-voltage lines, and thus shore up grid stability – here’s how it works.
Most of the US power grid uses alternating current, or AC, which constantly switches the direction of electron flow. But solar and battery storage uses direct current, or DC, that flows in a single direction.
The US power grid includes a smaller number of high-voltage DC lines that are more efficient at delivering bulk power over long distances or to remote regions.
Quarks are the smallest form of matter that we know of. So small, in fact, that studying it in any meaningful way has proven nearly impossible over the past several decades. That’s because quarks and their counterpart gluons are the small pieces of the puzzle that make up the nucleons in an atom.
Rachel Bronson, PhD, president and CEO, Bulletin of the Atomic Scientists, said: “We are living in a time of unprecedented danger, and the Doomsday Clock time reflects that reality. 90 seconds to midnight is the closest the Clock has ever been set to midnight, and it’s a decision our experts do not take lightly. The US government, its NATO allies and Ukraine have a multitude of channels for dialogue; we urge leaders to explore all of them to their fullest ability to turn back the Clock.”
The Doomsday Clock’s time is set by the Bulletin of the Atomic Scientists’ Science and Security Board with the support of the Bulletin’s Board of Sponsors, which includes 10 Nobel Laureates. Previously, the Doomsday Clock had been set at 100 seconds to midnight since 2020.
The Doomsday Clock statement explains that “Russia’s war on Ukraine has raised profound questions about how states interact, eroding norms of international conduct that underpin successful responses to a variety of global risks. And worst of all, Russia’s thinly veiled threats to use nuclear weapons remind the world that escalation of the conflict—by accident, intention, or miscalculation—is a terrible risk. The possibility that the conflict could spin out of anyone’s control remains high… Russia has also brought its war to the Chernobyl and Zaporizhzhia nuclear reactor sites, violating international protocols and risking widespread release of radioactive materials. Efforts by the International Atomic Energy Agency to secure these plants so far have been rebuffed.” The statement has been translated into Ukrainian and Russian.
Year 2012 The dwave quantum computers could essentially host the entire internet with low cost and even photonic room temperature quantum computers could eventually host the internet for even cheaper even down to pennies. Also if starling had casimir energy generators and casimir propulsion systems it could be even free for satellite operation costs with full automation we could essentially have low cost of pennies for the full system operation. At least some ideas for future operation costs.

The public perceives OpenAI’s ChatGPT as revolutionary, but the same techniques are being used and the same kind of work is going on at many research labs, says the deep learning pioneer.
Recent experiments conducted in Boston labs have shown reverse aging results among mice and could show similar results in people.
The combined experiments — which were conducted during a span of 13 years — published Thursday (January 12) in the scientific journalCell reported that old, blind mice regained eyesight, developed smarter brains and built healthier muscle and kidney tissue, challenging the theory that DNA was the only cause of aging, as it proved that chemical and structural changes to chromatin played a factor without altering genetic code.
The research showed that a breakdown in epigenetic information caused the mice to age and the restoration of the epigenome reversed aging effects.
We might all have been in a situation where we had to put our trust in our work to hold up and do what it needed to do, but Margaret Hamilton’s work was particularly important — it was responsible for putting Neil Armstrong and Buzz Aldrin on the moon in July 1969.
When warning lights started going off in the middle of the Eagle module’s descent toward the lunar surface, NASA faced a tough decision: continue with the landing or abort.
Margaret offered the world a great deal with her prowess, and I am glad Obama recognized her before her death, thank God she’s still with us today. #GodBlessHer
