As the holder of more than 270 patents in 27 countries—including 112 in the US alone—Tesla rightfully earned his place in history, but not every invention of Tesla made it to production. With that in mind, we combed through the records and found 7 of Tesla’s most substantial inventions that never got built.

A cherry-red pickup truck in Carmel, Indiana runs on hydrogen without carrying any fuel cells. The engineer who developed this “hydrogen-on-tap” system hopes it can someday power cargo trucks and cruise ships worldwide.

The city of Carmel, Ind., has trucks for plowing snow, salting streets, and carrying landscaping equipment. But one cherry-red pickup can do something no other vehicle can: produce its own hydrogen.

A 45-kilogram metal box sits in the bed of the work truck. When a driver starts the engine, the device automatically begins concocting the colorless, odorless gas, which feeds into the engine’s intake manifold. This prevents the truck from guzzling gasoline until the hydrogen supply runs out. The pickup has no fuel cell module, a standard component in most hydrogen vehicles. No high-pressure storage tanks or refueling pumps are needed, either.

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.

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, piezoelectric ceramics 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.”

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 light can carry angular momentum, 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 laser 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 metasurface 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.

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.

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 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.

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.
