The Earth is facing serious pollution: soil, water, air … Therefore, there have been many innovations and inventions launched to clean the environment and save the green planet, also the house and life. of our own.
These inventions give hope that if replicated, they can bring about big effects enough to change the situation.
1. Project to remove rubbish at sea
The Ocean Cleanup project was started by 23-year-old talented Boyan Slat from the Netherlands. The idea is to create giant screens floating on water and act as mini beaches. Just like the way rubbish washed up on the coast, taking advantage of ocean currents, these screens will passively collect and store it there. About 1 month, the ship will come and take the garbage to recycle.
Slat expects this technology to be widely implemented by 2020. According to calculations, floating screens will collect about 50% of the Large Waste Area in the Pacific in 5 years (Slat was previously estimated at 42% in 10 years).
2. biodegradable bags instead of plastic bags
Kevin Kumala, the founder of AVANI Eco, was worried that plastic bags would disrupt the ecosystem and affect the flora and fauna on the waters of Bali, Indonesia (his hometown).
But instead of advising people to limit their use of plastic bags, Kumala invented this eco-friendly biodegradable bag. It is made from natural roots of cassava and starch, even if the animal eats this bag it doesn’t matter.
3. Paper recycling machine
The size of this Epson PaperLab machine is quite large, but it can recycle wasted paper immediately into new paper.
When excess paper is fed into the machine, it is crushed into small pieces, after which the steam system removes ink from the paper. The pulp is then pressed into brand new paper with an optional size and thickness.
It is not compact, but it can recycle and produce 14 sheets of paper per minute, which is equivalent to 6700 sheets in 8 hours of work!
4. Seabin – trash for the sea
This smart bin was invented by two Australian surfer Andrew Turton and Pete Ceglinski.
These bins will be placed at the docks and ports, absorb water in and automatically retain the plastic debris floating on the water. It is also suitable for clearing oil slicks at sea.
This box has another advantage of low production and maintenance costs, so there are dozens of units currently operating in the world and more than 2000 ordered.
5. Edible water bubble
This compact invention was to replace plastic bottles or water containers. The outer membrane of this bubble is extracted from seaweed. Although the inventor does not encourage, you absolutely can eat this film to satisfy your curiosity, and naturally this ball of water is extremely environmentally friendly.
6. AIR-INK – pen ink from car dust
Anirudh Sharma, the creator of AIR-INK, believes that we can turn toxic things in the air into something useful – for example, turning car waste into ink.
First, a cartridge, similar to the one commonly used in printers, is mounted on car exhaust pipes to collect carbon soot. After that, the AIR-INK group used some special methods to remove harmful components, such as heavy metals.
The remaining raw carbon will create a high-grade black ink for pens. A pen like this is created by the exhaust of 40-50 minutes of driving and writing just like a regular pen.
7. Machines for making sand from beer bottles
New Zealand’s DB Breweries has crafted this sand crusher to encourage recycling of crockery. And the whole process from cork bottle to fine sand takes only 5 seconds.
When the bottle is put into the machine, a wheel with small steel hammers will crush the beer bottle. A suction system then takes away the silica dust and label peel, leaving about 200 grams of powder that can replace sea sand.
These sand powders will be brought to the beach to replace the contaminated sand. So from now on saving the beautiful beaches in the world becomes simpler than ever … drink more beer than usual.
8. Nebia water-saving showerhead
Did you know that 8 minutes of continuous showering will consume 20 liters of water?
Applying technologies in rockets and medical devices, this invention will save up to 70% of your shower water and absolutely not reduce the relaxation experience compared to a regular shower.
9. Wheat cans hold ring
Plastic water cans can be very dangerous when released into the environment, because marine animals can get stuck in them and cannot escape.
Saltwater Brewery in Florida leveraged the residual barley in the brewing process to make edible water retention rings. Recently this product has been improved to have the same durability as plastic or plastic casing, and even better.
The downside of this product is that the price is quite high, but nonetheless this is a great suggestion for beer and soft drink manufacturers who want to protect the environment.
Oumuamua: A mysterious object could be a satellite of an alien
Harvard scientists recently hypothesized that a mysterious object shaped like a cigar, the only one of its kind ever seen in our solar system, could be a satellite. was intentionally sent by the aliens to Earth.
A telescope located on the US Hawaiian Islands first discovered “Oumuamua” in October 2017. The name means “a messenger from a far, first come” in Hawaiian. This red, metallic-rich object measures 228m x 35m, moves fast to incomprehensible but does not revolve around the Sun.
On the contrary, it hovered between Mercury and the Sun, then fluttered across the Earth before leaving the Solar System. With this route, Oumuamua must be an interplanetary astronaut from outside our solar system.
Oumuamua’s orbit in 2017
Scientists initially called it a meteorite, and later assumed it was a comet in moderation. But Oumuamua does not show the typical signs of a comet, as the long tail of gas dust is often seen.
Later, some astronomers tried adjusting a high-power radio telescope toward this object to scan for radio signals. But they also found nothing.
Ever since the discovery of Oumuamua, scientists have been constantly wondering if it came from another intellectual life form?
In a recently published article, Harvard scientists Shmuel Bialy and Abraham Loeb suggested that the rotation and speed characteristics of Oumuamua could be derived from the motion of the solar engine. This means that the object has a component made of a thin layer of material that can absorb solar radiation – possibly a natural material that we have never seen before, or by outsiders. planet creation.
Oumuamua “could be a lightsail of artificial origin,” the article said. Lightsail is a scientific term for an object with solar radiation absorbing panels to create repulsive motion. People have tried devices like this before, but this idea has so far only stopped at pregnancy.
“It is likely that Oumuamua is a lightsail, a fragment of a device from a highly developed civilization, floating in the interstellar space,” the article wrote.
The idea that this object could belong to a larger device powered by the alien’s solar power is very similar to fiction, but the authors even proposed an “odd” explanation. more: “Oumuamua could be a complete satellite intentionally sent to nearby Earth from an alien civilization.”
The authors argue that if Oumuamua was just an innocuous innocuous rock, then we should have seen more of such objects. This, coupled with the strange movements of the object, shows that it has some kind of energy against gravity, the two scientists said.
Oumuamua passed the Earth on its way out of the solar system, so the distance between it and the Earth was too far for scientists to continue their research. So the origin, the behavior and what creates it will remain a mystery. The “strange” predictions of Harvard scientists will not be verified – just like the predictions of many others.
Loeb told NBC News that the story of Oumuamua could be created by aliens is “purely scientific and based on evidence.”
He also added: “I have followed Sherlock Holmes’s motto: when you eliminate the impossible, whatever remains, no matter how difficult it is, is certainly true. . “
