Quaise Energy, a startup based in Cambridge, Massachusetts, has announced its intentions to revolutionize how conventional power plants produce electricity. They have developed a new type of drilling technology that they claim will allow virtually any power plant to convert to geothermal as a fuel source.

The new technology uses a gyrotron-powered drilling platform that vaporizes a borehole by emitting millimeter-sized energy waves from the tip of a drill bit. Engineers at Quaise have been working to perfect the technology for the past decade. The energy waves pulverize the rock as the hole is dug, allowing for digging much deeper than conventional drills. The energy waves, notably, are generated on the surface—their frequency is near to that used by microwaves.

Once the hole is excavated, water can be pumped into its depths, where the heat from the Earth will convert it to steam that rises back up out of the hole like a geyser. Also, the well can be used indefinitely to produce electricity using a geothermal source of energy, making it cheaper to produce electricity than conventional methods.

Researchers from the Institute of High Energy Physics of the Chinese Academy of Sciences examined the validity of the theory of relativity with the highest accuracy in a study entitled “Exploring Lorentz Invariance Violation from Ultrahigh-Energy γRays Observed by LHAASO,” which was published in the latest issue of Physical Review Letters.

According to Einstein’s theory of relativity, the fastest speed of matter in the Universe is the speed of light. Whether that limit is breachable can be tested by examining Lorentz symmetry breaking or Lorentz invariance violation.

“Using the world’s highest energy gamma rays observed by the Large High Altitude Air-shower Observatory (LHAASO), a large-scale cosmic ray experiment in Daocheng, Sichuan province, China, we tested Lorentz symmetry. The result improves the breaking energy scale of Lorentz symmetry by dozens of times compared with the previous best result. This is the most rigorous test of a Lorentz symmetry breaking form, confirming once again the validity of Einstein’s relativistic space-time symmetry,” said Prof. Bi Xiaojun, one of the paper’s corresponding authors. Prof. BI is a scientist at the Institute of High Energy Physics and a member of the LHAASO collaboration.

In the quest for the perfect battery, scientists have two primary goals: create a device that can store a great deal of energy and do it safely. Many batteries contain liquid electrolytes, which are potentially flammable.

As a result, solid-state lithium-ion batteries, which consist of entirely solid components, have become increasingly attractive to scientists because they offer an enticing combination of higher safety and increased energy density—which is how much energy the battery can store for a given volume.

Researchers from the University of Waterloo, Canada, who are members of the Joint Center for Energy Storage Research (JCESR), headquartered at the U.S. Department of Energy’s (DOE) Argonne National Laboratory, have discovered a new solid electrolyte that offers several important advantages.

Russia’s diversified design bureau for marine engineering, Rubin, unveiled a project for a modified version of a submarine that the company is working on.

MOSCOW, ($1=76.79 Russian Rubles) — Russia’s diversified design bureau for marine engineering, Rubin, has unveiled a project for a modified version of the Guardian submarine that the company is working on. Rubin is the greatest designer of Soviet and Russian submarines – 85% of them are the work of the company.

According to preliminary data, the submarine is designed to reach a maximum speed of 21 knots. If it travels at 10 knots, it can travel a maximum of 4,000 miles. Ruby achieves this speed by integrating a more powerful power plant, as well as reducing the resistance to movement in the surface position.

It has elasto-magnetic properties that cause it to react to external forces or energy acting like a super rubber band.

Paroxysmal AF occurs when the upper chambers of the heart beat irregularly. Instead of initiating normal sinus rhythm, the two atria fibrillate or quiver. That doesn’t stop blood flowing from the upper to lower chambers, but it does upset the normal heartbeat causing the heart to race. In my case, the paroxysmal reference meant that my heart was going in and out of AF. Sometimes everything was normal. At other times I would experience a racing heartbeat exceeding 120 beats per minute and lasting from minutes to hours.

When an AF episode ends what happens inside the heart? An apt analogy is the electric control panel in every home that either contains circuit breakers or fuses. When lights go out you can go to the box to reset a tripped circuit or replace a blown fuse. In Paroxysmal AF that reset is automatic with the heartbeat returning to normal sinus rhythm.

So where does conversion come into the conversation? I had worn a Holter Monitor (a portable ECG device) for 14-days back in the latter part of November of last year. In this pandemic-disrupted world, it took a while before a cardiologist got back to me about what the Holter showed. In a video call last week I learned about conversion in an entirely new context. The cardiologist told me that over the two weeks of wearing the Holter Monitor I had been in AF for 8.5% of the time and had experienced seven conversion pauses lasting between 3.5 and 5 seconds. A pause is exactly what you think it means. If we carry the analogy of the fuse box, it is as if a power fluctuation caused the lights to go out and it took five seconds to reset the circuit breaker for them to come back on. The cardiologist said the AF occurrences were less of a concern than the conversion pauses, particularly one lasting 5 seconds (apparently happened in my sleep).

Researchers from Chalmers University of Technology have produced a structural battery that performs ten times better than all previous versions. It contains carbon fiber that serves simultaneously as an electrode, conductor, and load-bearing material. Their latest research breakthrough paves the way for essentially ’massless’ energy storage in vehicles and other technology.

The batteries in today’s electric cars constitute a large part of the vehicles’ weight, without fulfilling any load-bearing function. A structural battery, on the other hand, is one that works as both a power source and as part of the structure – for example, in a car body. This is termed ‘massless’ energy storage, because in essence the battery’s weight vanishes when it becomes part of the load-bearing structure. Calculations show that this type of multifunctional battery could greatly reduce the weight of an electric vehicle.

We’re big fans of this big fan.

There’s a new, more fuel-efficient airliner engine on the scene, as Rolls-Royce has started work on its UltraFan aero engine. The gigantic fan engine gets 25 percent better mileage compared with its predecessor, and Rolls-Royce says it will revolutionize passenger and cargo flight around the world.

The first demonstrator engine will be finished by the end of 2021. Rolls-Royce revealed more details in a statement:
