Great new episode with the Smithsonian’s Jeremy R. Kinney. We discuss all aspects of how the seemingly mundane propeller drove the 20th Century’s revolution in aerospace and helped usher in an era of global warfare, travel, and trade.

Without the lowly propeller, global trade and commerce and freedom of movement as we knew it prior to Covid would have never had the opportunity to flourish. Special guest Jeremy R. Kinney, Chair of the Aeronautics Department at the Smithsonian Institution’s National Air and Space Museum in Washington, D.C., provides a fascinating narrative to how and why advances in aircraft propeller technology enabled aerospace to revolutionize global warfare, travel, and trade. Author of “Reinventing the Propeller,” Kinney and I discuss many underappreciated aspects of this aeronautical workhorse.

A new Tesla software leak revealed that the automaker is planning to bring a HEPA filter, enabling Tesla’s Bioweapon Defense Mode, to Model Y.

With the Model X and later the Model S, Tesla has started to put massive HEPA-rated air filters inside its vehicles.

The idea is for Tesla to put efforts into developing a more powerful air filtering system in order to not only contribute to the reduction of local air pollution with electric vehicles but also to reduce the direct impact of air pollution on the occupants of its vehicles.

Adding hypersonic missiles to the arsenal of dozens of Arleigh Burke class destroyers could be a very expensive and labor intensive endeavor.

The Navy is exploring new options for replenishing its submarines out at sea, which could have broader impacts on how it resupplies all of its fleets.

“The SPEAR flight demonstrator will provide the F/A-18 Super Hornet and carrier strike group with significant improvements in range and survivability against advanced threat defensive systems,” Mercer, the firm’s SPEAR program manager, added.

Very-long-range, high-speed strike weapons could be very valuable for the Navy’s carrier air wings, especially as potential near-peer adversaries, such as China and Russia, continue to develop and field increasingly longer-range and otherwise more capable surface-to-air missile systems and associated radars and other sensors. Aircraft carriers and their associated strike groups and air wings are also increasingly at risk from various anti-access and area-denial capabilities, further underscoring the need for weapons with greater range and that are able to prosecute targets faster to help ensure their survival.

F-22 Raptors from the North American Aerospace Defense Command, or NORAD, intercepted a group of Russian aircraft in international airspace near Alaska Monday night.

In a series of tweets early Tuesday morning, NORAD said the Raptors intercepted a pair of Russian Tu-95 “Bear” bombers escorted by Su-35 fighters. NORAD said it also identified a Russian A-50 airborne early warning and control aircraft supporting the other Russian planes that “loitered” in the Alaska Air Defense Identification Zone and came within 30 nautical miles of Alaska’s shore.

NORAD said that all Russian aircraft remained in international airspace and at no time entered U.S. or Canadian airspace.

Fusion power is the technology that is thirty years away, and always will be – according to skeptics at least. Despite its difficult transition into a reliable power source, the nuclear reactions that power the sun have a wide variety of uses in other fields. The most obvious is in weapons, where hydrogen bombs are to this day the most powerful weapons we have ever produced. But there’s another use case that is much less destructive and could prove much more interesting – space drives.

The concept fusion drive, called a direct fusion drive (or DFD) is in development at the Princeton Plasma Physics Laboratory (PPPL). Scientists and Engineers there, led by Dr. Samuel Cohen, are currently working on the second iteration of it, known as the Princeton field reversed configuration-2 (PFRC-2). Eventually the system’s developers hope to launch it into space to test, and eventually become the primary drive system of spacecraft traveling throughout our solar system. There’s already one particularly interesting target in the outer solar system that is similar to Earth in many ways – Titan. Its liquid cycles and potential to harbor life have fascinated scientists since they first started collecting data on it.

Sun Tzu said all warfare is based on deception. Today, that means electronic deception.

The video could be the first visual evidence that China is actively testing an air-launched hypersonic weapon.
