Scientists have used mushrooms to make biodegradable computer chips

Posted by in categories: computing, sustainability

Year 2022 😗😁


Foraging for fungi may not only mean mushrooms are on the menu. New research has shown that mushroom skins could provide a biodegradable alternative to some plastics used in batteries and computer chips, making them easier to recycle.

Researchers from the Johannes Kepler University in Austria were working on flexible and stretchable electronics, with a focus on sustainable materials to replace non-degradable materials, when they made their discovery, published in the journal Science Advances Friday.

AI comes to the farm: New technology tackles acres of weeds quickly by using robotics and lasers

Posted by in categories: business, food, robotics/AI, sustainability

Weeds are one of the most “tedious, time-consuming and challenging” elements of farming, Carbon Robotics told Fox Business via email.

The LaserWeeder can eliminate over 200,000 weeds per hour and offer up to 80% cost savings in weed control.

Carbon Robotics CEO and founder Paul Mikesell “knows farmers and has a lot of friends who are farmers,” he said.

This tiny glass pyramid could make solar panels cheaper than ever

Posted by in categories: solar power, sustainability

Photovoltaic cells work best when sunlight is incident directly on them. To make the most of sunlight available during the day, scientists have relied on solar tracking to move panels in sync with the Sun as its travels across the sky. However, installing these systems increases the cost of deploying solar panels, which is a significant obstacle to their wide-scale adoption.

Flipper hacking device on track to make $80M worth of sales

Posted by in categories: cybercrime/malcode, sustainability, transportation

You may have stumbled across the Flipper Zero hacking device that’s been doing the rounds. The company, which started in Russia in 2020, left the country at the start of the war and moved on since then. It claims it no longer has ties to Russia and that it is on track to sell $80 million worth of its products this year after selling almost $5 million worth as Kickstarter preorders — and it claims it sold $25 million worth of the devices last year.

So what are they selling? Flipper Zero is a “portable gamified multi-tool” aimed at everyone with an interest in cybersecurity, whether as a penetration tester, curious nerd or student — or with more nefarious purposes. The tool includes a bunch of ways to manipulate the world around you, including wireless devices (think garage openers), RFID card systems, remote keyless systems, key fobs, entry to barriers, etc. Basically, you can program it to emulate a bunch of different lock systems.

Inside the startup creating the future of food production

Posted by in categories: food, sustainability

In a 1931 essay, Winston Churchill wrote about how he sees the future of food production: “We shall escape the absurdity of growing a whole chicken in order to eat the breast or wing, by growing these parts separately under a suitable medium,” he wrote.

Fast forward some 90 years, and Churchill’s prediction is coming true, thanks in part to Israeli food-tech company Aleph Farms, which has developed a unique method to cultivate steak meat from isolated cow cells.

This salty gel could harvest water from desert air

Posted by in categories: materials, sustainability

MIT engineers have synthesized a superabsorbent material that can soak up a record amount of moisture from the air, even in desert-like conditions.

As the material absorbs water vapor, it can swell to make room for more moisture. Even in very dry conditions, with 30 percent relative humidity, the material can pull vapor from the air and hold in the moisture without leaking. The water could then be heated and condensed, then collected as ultrapure water.

The transparent, rubbery material is made from hydrogel, a naturally absorbent material that is also used in disposable diapers. The team enhanced the hydrogel’s absorbency by infusing it with lithium chloride — a type of salt that is known to be a powerful dessicant.

Passive cooling system could benefit off-grid locations

Posted by in categories: food, solar power, sustainability

As the world gets warmer, the use of power-hungry air conditioning systems is projected to increase significantly, putting a strain on existing power grids and bypassing many locations with little or no reliable electric power. Now, an innovative system developed at MIT offers a way to use passive cooling to preserve food crops and supplement conventional air conditioners in buildings, with no need for power and only a small need for water.

The system, which combines radiative cooling, evaporative cooling, and thermal insulation in a slim package that could resemble existing solar panels, can provide up to about 19 degrees Fahrenheit (9.3 degrees Celsius) of cooling from the ambient temperature, enough to permit safe food storage for about 40 percent longer under very humid conditions. It could triple the safe storage time under dryer conditions.

The findings are reported today in the journal Cell Reports Physical Science, in a paper by MIT postdoc Zhengmao Lu, Arny Leroy PhD ’21, professors Jeffrey Grossman and Evelyn Wang, and two others. While more research is needed in order to bring down the cost of one key component of the system, the researchers say that eventually such a system could play a significant role in meeting the cooling needs of many parts of the world where a lack of electricity or water limits the use of conventional cooling systems.
