The Rise of the Fifth Reich?

Posted by in categories: energy, finance, policy

Over at the always interesting Small Wars Journal, Tony Corn has a stimulating piece on the implications of the European crisis for world politics. He sees a clueless German policy establishment recklessly moving toward an unsustainable quest for power reminiscent in too many ways of problems Germany has had in its past.

Germany, warns Corn, is planning to use its financial domination of Europe to remake the EU into an extension of German power — more or less the way that Prussia used the Zollverein to bring northern Germany under its control and then dominated the Bismarckian Reich through a rigged constitutional system. Once that is in place, he writes, the Germans will continue their policy of deepening relations with Russia at the expense of NATO and transatlantic ties, and end Europe’s embargo on arms sales to China.

As an analyst, Corn sometimes goes to what we more placid types at VM consider overexcited conclusions about Eurasian power realignments. Safely ensconced among the storied oaks and elms, gazebos, pergolas, ha-has, follies and deer parks surrounding the stately Mead manor in glamorous Queens, we tend to take a wait-and-see attitude toward organizations like the Shanghai Cooperation Organization which Russia and China have sometimes posited as a kind of embryonic counter-NATO. Corn, in our perhaps excessively complacent view, can be too quick to take vague Eurasian fantasies and aspirations about diplomatic revolutions as accomplished facts; it is easier to dream about firm Russian and Chinese anti-US cooperation than for those two countries to make it work. But that said, there is no doubt that Corn’s industry, historical grounding and sensitive, even over-sensitive nerve endings give him the ability to produce original and striking ideas.

A new flexible piezoelectric composite for 3D printing

Posted by in categories: 3D printing, energy

Researchers at Peking University, Southern University of Science and Technology and the University of Jinan in China have recently designed a ceramic-polymer composite that can be used to print complex 3D grid architectures. This composite, first presented in a paper published in Nano Energy, was found to exhibit a number of desirable properties, including high flexibility and a high electromechanical energy conversion rate.

Piezoelectric ceramic materials, such as Pb(Zr, Ti)O3 (PZT) typically have remarkable electromechanical energy conversion capabilities. However, most of these materials are inherently rigid, which makes them far from ideal for the fabrication of flexible electronics.

“Normally, are brittle, therefore, they are not suitable for integration into flexible electronics directly,” Shuxiang Dong, one of the researchers who carried out the study, told TechXplore. “We wanted to develop a 3D-printed, soft piezoelectric ceramic composite material that is a heat-curable polymer exhibiting mechanical flexibility and a large electromechanical voltage in response to environmental mechanical vibrations or force stimuli. Luckily, we made it, and our composite has great potential to be used for future soft sensors.”

New metasurface laser produces world’s first super-chiral light

Posted by in categories: energy, nanotechnology, physics

Researchers have demonstrated the world’s first metasurface laser that produces “super-chiral light”: light with ultra-high angular momentum. The light from this laser can be used as a type of “optical spanner” to or for encoding information in optical communications.

“Because can carry angular , it means that this can be transferred to matter. The more angular momentum light carries, the more it can transfer. So you can think of light as an ‘optical spanner’,” Professor Andrew Forbes from the School of Physics at the University of the Witwatersrand (Wits) in Johannesburg, South Africa, who led the research. “Instead of using a physical spanner to twist things (like screwing nuts), you can now shine light on the nut and it will tighten itself.”

The new produces a new high purity “twisted light” not observed from lasers before, including the highest angular momentum reported from a laser. Simultaneously the researchers developed a nano-structured that has the largest phase gradient ever produced and allows for high power operation in a compact design. The implication is a world-first laser for producing exotic states of twisted structured light, on demand.

Air Force plans May start on $218 million conversion of new ‘nuke sniffer’ planes for Offutt fleet

Posted by in categories: energy, existential risks, transportation

Replacements are on the way for two decrepit 55th Wing jets that give the Air Force critical information about nuclear detonations in North Korea and elsewhere in the world.

The giant defense contractor L3Harris and the Air Force’s “Big Safari” acquisitions group are scheduled to start in May converting the first of three former Air National Guard fuel tankers into WC-135R radiation-detection aircraft. Work will start on the other two next year.

When they’re finished, all three aircraft will be assigned to the 55th Wing at Offutt Air Force Base. The first is scheduled for delivery in 2022, said Maj. Malinda Singleton, an Air Force spokeswoman, with the other two following in 2023.

Electric control of a spin current has potential for low-power computing

Posted by in category: energy

The development of low-power methods for controlling a property of electrons known as spin could help to maintain the historic rates of progress that are occurring in computational power. Just such a method has now been reported. A device that permanently switches spin-orbit coupling.

Elon Musk hypes up Tesla smart home HVAC, hints at Cybertruck feature

Posted by in categories: Elon Musk, energy, sustainability, transportation

Elon Musk seems to be really interested in Tesla expanding into the home HVAC industry — going as far as saying that he is “dying to do it.”

He first brought up the idea in an interview on the Joe Rogan Experience almost two years ago.

Air Force F-X concept: a fuel-sipping electric fighter jet for 2030

Posted by in categories: energy, military

Circa 2011


The U.S. Air Force is working to produce its next-generation fighter jet, and word has it that the energy around the project is going to be electric. Literally.

It’s called the “F-X” concept (not to be confused with the VFAX/VFX/FX concepts of the 1960s and ’70s) and it’s intended to enter service in 2030.

The U.S. Army Plans To Field the Most Powerful Laser Weapon Yet

Posted by in categories: energy, military

O,.o woah o.o


The U.S. Army is pushing forward with plans for the most powerful laser weapon to date. The Indirect Fires Protection Capability-High Energy Laser (IFPC-HEL) will be a 250 to 300 kilowatt weapon, up to 10 times more powerful than the U.S. Navy’s Laser Weapon System. The power boost should be enough to destroy targets as large as incoming cruise missiles.
