Air Free Concept bike tires will never go flat, never get a puncture

Add as a preferred source on Google

Which cyclists would be willing to shell out for tires that can never get a puncture, never need to be inflated, and promise to never go flat? The wishful answer that Bridgestone is banking on is: All of them.

Bridgestone first demoed its prototype Air Free Concept tires in the simpler days of 2011 at the Tokyo Auto Show. At the time, the nine-inch wheels — based on a solid tire design, featuring thermoplastic-resin spokes — was still just a concept. Fortunately, in the six years between then and now, the company turned it into something more closely approximating reality — and this week we got a sneak peak.

The next-generation bicycle tires are intended to eliminate the need for traditional tires that require inflation, by using a unique (and, we presume, legally protected) array of spokes that run along the inner sides of the tires. The most obvious advantage to Air Free Concept tires is the fact that users will never be struck down with a flat tire again, nor will they need to carry a bicycle pump.

Beyond this, however, the tires are more environmentally friendly due to their efficient use of resources and Bridgestone promises that the “high flexibility for design granted by resin has also enabled proposals of next-generation bicycles which have never been seen before.”

Sadly, you will be waiting a while before you can get your hands on the Air Free Concept tires. That is because Bridgestone Corporation and Bridgestone Cycle Co. — the two companies partnering on the project — are still carrying out feasibility studies to make sure everything is hunky dory. Provided that it is, the plan is for the new tires to be available in 2019.

Hopefully, after all is said and done, blowouts, outer surface punctures, and other tire-deflating irritants will go the way of unnecessarily heavy steel frames and rock-hard leather seats. What a time to be alive!

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.

Starlink V5 is here, and it’s lighter, smarter, and far more efficient
The next-generation satellite internet kit promises improved efficiency while maintaining high-speed connectivity.
Starlink V4 vs V5

Not every hardware upgrade needs to be about speed. With Starlink V5, SpaceX is betting that a lighter design and lower power consumption matter just as much. The company has officially introduced its next-generation Starlink V5 kit, featuring a smaller and lighter design with significantly improved power efficiency.

Smaller, lighter, and far more efficient
