Inventors may be considered eccentrics and even crazy, but they move the world forward. And inventions that seem useless at first glance may surprise you at second glance.
Here are the top 7 unusual innovations that will find practical application
7. Peel-off superglue
Superglue holds firmly, but sometimes it needs to be peeled off and glued again. And that's where a snail comes to the rescue! Or rather, its mucus, which scientists from Philadelphia studied to create a reversible superglue.
Snail mucus hardens as it dries. This creates a structure that is both protective and sticky. It is called an epiphragm. It insulates the snail inside its shell, protecting it from predators. As the temperature drops in the evening and humidity increases, the mucus liquefies. The snail can now move and continues on its way.
Reversible superglue works on the same principle. When hydrated, it becomes soft and sticky, and when dry, it bonds like regular superglue. For most glues, surface roughness is a problem because it reduces the amount of contact between the glue and the surface. This makes the glue less sticky. But reversible superglue fills in these tiny gaps, creating a tight bond. And it can theoretically support the weight of a person.
6. The whitest paint in the world
What we perceive as a white shade or color in everyday life is never pure white. True white is a rare color that can only be observed in unfiltered sunlight, just as pure black can only be found in the depths of a black hole.
But now everything has changed thanks to scientists from Purdue University in Indiana. They have created the whitest acrylic paint known to mankind. This discovery was included in the Guinness Book of World Records.
The new composition is capable of reflecting 98.1% of solar radiation. That is, everything that is painted with this composition will absorb significantly less heat than surrounding objects. According to scientists, using the whitest paint in the world to paint the roof of a 93-square-meter building will cool it by 10 kilowatts. Then you won’t even need an air conditioner.
5. A toilet that analyzes health based on feces
Toto, a company known for its variety of bathroom products, unveiled a number of new products at CES 2021, including a smart toilet that analyzes skin and feces as a person empties their bowels.
Then, via a mobile app, the toilet owner receives recommendations on how to improve their health.
Toto claims that such a smart toilet could hit the market in the next few years. “A lot of data about well-being can be collected from feces,” the company says.
4. Ninu SMART perfume
This patent-pending smart perfume is controlled via a dedicated app. Each tube contains three different scents, allowing you to choose according to your mood or occasion, and even combine scents.
The app can also be used to tone down the scent or add an exotic twist.
Ninu SMART 100% is made with vegan, sustainably sourced ingredients, is phthalate, paraben and sulfate free and has over a million scents to choose from.
3. Self-healing plastic
"Just add water!" - this slogan can partially describe the new generation of plastic, which quickly recovers underwater even in harsh conditions. It retains its strength after self-healing, so it can be useful in emergency situations at sea, for example, in case of damage to an oxygen tank.
Scientists at China's Tsinghua University developed the material, called Rapid Underwater Self-Healing Rigid Elastomer (RUSSE), because most self-healing polymers do not work well underwater.
2. Device for communicating with the Venus flytrap
The title of this headline sounds like you're about to watch a B-movie horror movie, right? But the device itself isn't a horror prop, and it might even be useful.
The team, which works at Nanyang Technological University, has equipped the Venus flytrap with a tiny electrode communicator. It picks up electrical signals emitted by the plant and responds with pulses of its own.
Researchers hope the technology could be used to detect early signs of problems in valuable crops.
1. Contraceptive bath for testicles
This ultrasonic bath, developed by Rebecca Weiss, could be a game changer in male contraception.
Currently, condoms are available to men, which are useful for preventing sexually transmitted diseases but are inconvenient for most partners as continuous pregnancy prevention, and vasectomy, perhaps the safest but irreversible method of birth control.
Weiss' invention is a small, smooth cup that uses ultrasound waves to temporarily interrupt sperm regeneration, allowing a man to have safe (in terms of conception) sex for two weeks.
All the user has to do is fill the container with warm water and place their testicles in. The mechanism has been successfully tested on animals, but has not yet been used on humans.
