Scientists Make Hardened Wooden Knife That’s 3x Sharper Than Stainless-Steel

Posted by in categories: materials, sustainability

The sharpest knives available are made of either steel or ceramic, both of which are man-made materials that must be forged in furnaces under extreme temperatures. Now, researchers have developed a potentially more sustainable way to make sharp knives: using hardened wood. The method, presented October 20th, 2,021 in the journal Matter, makes wood 23 times harder, and a knife made from the material is nearly three times sharper than a stainless-steel dinner table knife.

“The knife cuts through a medium-well done steak easily, with similar performance to a dinner table knife,” says Teng Li, the senior author of the study and a materials scientist at the University of Maryland. Afterward, the hardened wood knife can be washed and reused, making it a promising alternative to steel, ceramic, and disposable plastic knives.

Li and his team also demonstrated that their material can be used to produce wooden nails as sharp as conventional steel nails. Unlike steel nails, the wooden nails the team developed are resistant to rusting. The researchers showed that these wooden nails could be used to hammer together three boards without any damage to the nail. In addition to knives and nails, Li hopes that, in the future, the material can also be used to make hardwood flooring that is more resistant to scratching and wear.

This Off-Grid Water Desalination Plant Does Not Use Up Any Electricity

Posted by in categories: energy, sustainability

Scientists are coming up with practical and cheaper desalination processes for water. It has been going on since half a century ago in Spain. Currently, Ikaria, a Greek island, got access to clean water by virtue of desalination.

The common method used in the process is called reverse osmosis (RO) but it has to be connected to the electricity grid. This is expensive and inaccessible for areas far from the grid. So, researchers have come up with sustainable off-grid desalination systems that run on renewable energy.

Now, microbial desalination cells (MDCs) are being suggested to use. This is developed by MIDES. It produces drinkable water from the sea. It means electro-active bacteria desalinate and sterilize water making it suitable and safe. “This technology offers new options to provide clean water and wastewater treatment to small, isolated locations without electricity,” said Frank Rogalla, director of innovation and technology at Aqualia and a member of the project team.

Increasing Sustainable Logging Practices With The Help Of AI

Posted by in categories: climatology, habitats, robotics/AI, sustainability

In recent years, the continued exploitation of natural resources and depletion of our forests has been a major issue, to say the least. The fight for sustainability has become increasingly important as we face the challenge of climate change and its effects on our planet. One possible solution to this problem is to use artificial intelligence (AI) to help increase sustainable logging practices.

Beyond data science, AI can be used in conjunction with autonomous robots that are specially designed for forestry work which may provide an answer for this global problem. AI can be applied specifically to logging operations such as planning where trees should be cut down and predicting the best time of day for cutting trees so they do not disrupt nesting birds or other animal habitats.

Elon Musk Has Disrupted the Auto and Space Industries. 1 More Thing He Can Add to His Resume

Posted by in categories: Elon Musk, space travel, sustainability

Elon Musk has built two industrial behemoths— Tesla and SpaceX—revolutionizing two industries along the way. But that’s not all he has done to change global industry.

Musk has also given manufacturing companies a new word: gigafactory.

The practical definition of a gigafactory is a larger, modern manufacturing facility for products that are designed to lower global carbon emissions.

Hydroponics made Fujitsu

Posted by in categories: business, computing, finance, food, sustainability

Fijitsu retrofitted one of it’s clean rooms in a vertical farm. The project was so successful, they discovered they could enter a new market segment and sell the systems themselves. I definately want one.

Like the giant monolith in Stanley Kubrick’s 2,001 this new head of lettuce is simultaneously a product of this factory’s past and the future. Fujitsu is a space-age R&D innovator with sprawling, specialized factories. But several of its facilities, including this one, went dark when the company tightened its belt and reorganized its product lines after the 2008 global financial crisis. Now in the aftermath, it has retrofitted this facilities to serve tomorrow’s vegetable consumers, who will pay for a better-than-organic product, and who enjoy a bowl of iceberg more if they know it was monitored by thousands of little sensors.
