Good Thinking

When it comes to air travel, wheelchair users definitely face some challenges. That's where the Revolve Air wheelchair comes in, as it can be folded up – wheels and all – to qualify as carry-on baggage.

While it's important to find homes for the houseless, the truth is that many people will stay living on the street in the meantime. The Mini Mansion is made with that fact in mind, as a portable and better equipped alternative to current options.

In order to smuggle illegal drugs into prisons, people are now soaking materials like paper and fabric in such drugs, letting the materials dry, then passing them along to inmates. A new portable device, however, sees through that ruse.

Nobody wants to live in a drafty house, yet checking for substantial air leaks within a home can be a complex process. Scientists have now devised what could be a much easier method of doing so, utilizing a technique that dates back to 1864.

Hog barns typically aren't the nicest places to be at the best of times, but try living in one during a heat wave. Scientists at Indiana's Purdue University have developed a self-activating hog-cooling pad for just such situations.

A great deal of peel, pulp and stone waste is constantly being generated in the production of olive oil. And while that waste is often just dumped or incinerated, it could soon be used as a source of valuable antioxidants.

QR codes are everywhere nowadays, but they don’t have to be. MIT scientists have developed an invisible tagging system called BrightMarker, which embeds fluorescent tags into objects that can be viewed and tracked through an infrared camera.

The Draft Top is designed to take your beer can (and other drinks) to a new level. It cleanly and smoothly removes the lid from an aluminum vessel, allowing for better taste, less bloat, imaginative creations and, afterwards, some clever repurposing.

When a road is covered in snow or obscured by fog, the navigation systems of self-driving cars may have trouble seeing where that road is. Specially equipped pavement markers could help, by continuously transmitting radio signals to passing vehicles.

For wheelchair users, air travel can be a cumbersome and frustrating experience. That's where a new type of airliner seat is designed to come in, as it allows passengers to stay in their own wheelchair throughout the flight.

Although interchangeable-bit hex wrenches aren't that hard to use, there's always room for improvement … right? The designers of the Switch Hex T seem to think so, as their wrench features a carousel-like multi-bit rotating head.

While studies show that natural human breast milk is the best food for babies, storing the stuff in a frozen state has its drawbacks. That's where a new laser-enabled system comes in, which allows milk to be powdered without any loss in nutrients.

Blind people using white canes are limited in how fast they can walk, as they have to wait for their cane to hit obstacles before going around them. The NextGuide cane is different, in that it steers users around obstacles that they've yet to reach.

While metal detectors are useful for detecting land mines, they can be fooled by buried metallic debris … plus some mines don't contain any metal. A new system is claimed to work better, by reading the molecular signature of explosives used in mines.

Just like pharmaceuticals, banknotes and alcoholic beverages, the crop seeds sold to farmers are frequently counterfeits. MIT scientists have devised a method of spotting the fakes, by tagging genuine seeds with silk dots.
