The inventor behind the Maglev train is back with a Hyperloop for launching space vehicles

You may be familiar with the name James Powell, a prolific inventor who, back in 2000, was one half of the team behind the superconductive magnetic levitation train — which went on to inspire the ultra-fast Tokyo to Osaka maglev train.

Well, Powell last year filed a patent application for a related concept: a “SpaceTram” maglev rocket launcher that would eschew chemical propellants in favor of magnets for launching a rocket into space. If made a reality, this would be a new way to achieve magnetic levitation, stabilization, and propulsion for a space launch.

The big challenge, of course, would be gaining the necessary propulsion, which Powell thinks could be achieved using a vacuum launch tube with electrically-conducting rails, similar to Elon Musk’s Hyperloop concept.

It’s a neat, if ridiculously ambitious concept, and this week it received the video treatment from YouTuber Deepak Gupta, who runs the PatentYogi channel. The video itself paints a picture of what the technology might actually look like were it brought to life — and, while we’re certainly skeptical, it still looks pretty awesome.

“Patents are one of the tools that engineers use to express their creativity,” Gupta told Digital Trends. “[The] general public finds it easy to understand how a new product works, how it might solve some problems they face and how it may change their lives. However, patents are in a format that is largely inaccessible. A patent document is full of legalese and complex drawings, so most patents go unnoticed. We at PatentYogi want to make patents accessible to the general public.”

Gupta said that he selects patents that he finds interesting himself, although he’s not sure whether we’ll ever really get to see this particular concept in action. It would certainly be well-received were it to actually work, though.

“Recently there has been a greater demand for space launch systems to launch small satellites cost effectively,” Gupta said. “Just a few weeks back, an ISRO mission launched 104 satellites — mostly small satellites — in a single mission, so the technology disclosed in the patent has a great market demand.”

Anti-surveillance clothing is getting cheaper, but don’t expect an invisibility cloak
Affordable shirts now claim to confuse facial recognition, although their protection depends heavily on the camera and software watching you
Chart, Plot, Adult

Anti-surveillance clothing is starting to look less like an art-school experiment and more like something you could actually wear outside. Shirts designed to confuse facial recognition systems now cost about as much as ordinary streetwear, although buying one won’t make you disappear.

The Guardian reports that designers are using face-like prints, unusual cuts and infrared lights to interfere with computer vision. These techniques target specific weaknesses, so their success depends on what happens to be watching you.

This spinning drone hides in plain sight using a visual illusion
This drone doesn't turn invisible. It tricks your brain into thinking it has.
Phantom Twist

For decades, engineers have chased the dream of an invisible drone. The usual approaches have involved transparent materials, camouflage coatings, or complex optical systems that bend light around an object. Researchers at Northwestern University decided to take a completely different route. Instead of hiding the drone itself, they chose to fool the human eye.

The result is Phantom Twist, an experimental drone that spins so rapidly it almost disappears into the background. It's not technically invisible, but to anyone watching, it looks more like a faint blur than a flying machine.

This smart knitted fabric can flip switches, count your steps, and even change shape
Grandma's knitting just entered its Iron Man era

For most of us, knitting brings to mind sweaters, scarves, and perhaps an ambitious grandmother determined to make winter more fashionable. Researchers at Harvard University, however, have a far more futuristic vision. They've transformed ordinary knitted fabric into a programmable material capable of changing shape, acting as an electrical switch, sensing movement, and potentially forming the foundation of tomorrow's wearable technology.

The research, published in Advanced Functional Materials by scientists at the Harvard John A. Paulson School of Engineering and Applied Sciences (SEAS), demonstrates how machine-knitted textiles can "snap" between multiple stable shapes without relying on motors or rigid mechanical parts.
