Engineers produce the world’s longest flexible fiber battery

Posted by in categories: computing, sustainability, wearables

Researchers have developed a rechargeable lithium-ion battery in the form of an ultra-long fiber that could be woven into fabrics. The battery could enable a wide variety of wearable electronic devices, and might even be used to make 3D-printed batteries in virtually any shape.

The researchers envision new possibilities for self-powered communications, sensing, and computational devices that could be worn like ordinary clothing, as well as devices whose batteries could also double as structural parts.

In a proof of concept, the team behind the new battery technology has produced the world’s longest flexible fiber battery, 140 meters long, to demonstrate that the material can be manufactured to arbitrarily long lengths. The work is described today in the journal Materials Today. MIT postdoc Tural Khudiyev (now an assistant professor at National University of Singapore), former MIT postdoc Jung Tae Lee (now a professor at Kyung Hee University), and Benjamin Grena SM ‘13, Ph.D. ‘17 (currently at Apple) are the lead authors on the paper. Other co-authors are MIT professors Yoel Fink, Ju Li, and John Joannopoulos, and seven others at MIT and elsewhere.

This sustainable desalination pod makes seawater drinkable naturally

Posted by in category: sustainability

The James Dyson Award recently recognized a team of Malaysian designers for their sustainable desalination pod concept called WaterPod that works on solar distillation to convert seawater into drinkable water. Developed by Bennie Beh Hue May, Yap Chun Yoon, and Loo Xin Yang, the WaterPod is designed to be floated at sea, and therefore accessible to sea nomads.


WaterPod is a low-cost yet environmentally-friendly desalination method to generate drinkable water.

Shellac for printed circuits

Posted by in categories: 3D printing, robotics/AI, sustainability

More precise, faster, cheaper: Researchers all over the world have been working for years on producing electrical circuits using additive processes such as robotic 3D-printing (so-called robocasting) with great success, but this is now becoming a problem. The metal particles that make such 3D substrates electrically conductive are exacerbating the problem of electronic waste, especially since the waste generated is likely to increase in the future in view of new types of disposable sensors, some of which are only used for a few days.

This constitutes unnecessary waste, according to Gustav Nyström, head of Empa’s Cellulose & Wood Materials lab: “There is an urgent need for materials that balance electronic performance, cost and sustainability.” To develop an environmentally friendly ink, Nyström’s team therefore set ambitious goals: metal-free, non-toxic, biodegradable. And with in mind: easily formable and stable to moisture and moderate heat.

China EV teardown: A $4,500 ‘alternative to walking’

Posted by in categories: sustainability, transportation

SAIC-GM-Wuling uses cheap parts but makes them easy to replace.


TOKYO — At 28,800 yuan ($4,500), the Hongguang Mini EV has become a big seller in certain Chinese cities and villages. In Japan, a Nagoya University professor disassembled the electric vehicle to discover what kind of alchemy the manufacturer used to set such a low price.

Researchers enable nanoscale metal parts using new 3D printing technology

Posted by in categories: 3D printing, chemistry, nanotechnology, sustainability

Researchers from ETH Zurich and Nanyang Technological University (NTU) have developed a new 3D printing technique capable of producing nanoscale metal parts.

Based on an electrochemical approach, the process can be used to fabricate copper objects as small as 25 nanometers in diameter. For reference, an average human hair is around 3000x thicker at 75 microns.

According to the research team led by Dr Dmitry Momotenko, the new 3D printing technique has potential applications in microelectronics, sensor technology, and battery technology.

Vertical “indoor garden” produces 21000 fresh vegetables every day

Posted by in category: sustainability

The largest indoor vegetable farm in Japan.

An indoor farm called Spread in Kameoka – west of Tokyo has been opened to eliminate the barrier of weather and meet the demand for fresh vegetables all year round. So every day, up to 21,000 lettuce plants are harvested to be shipped across Japan, all delivered to stores and supermarkets within 24 hours of leaving the farm.

Elation Unveils a Prototype of Its 1,400 HP Electric Hypercar, and It’s Named After a Hunting Dog

Posted by in categories: sustainability, transportation

Exactly one month ago today, Elation Hypercars threw its hat into the ring and unveiled its first four-wheeled beast known as Freedom. The all-electric hypercar, which promises a staggering 1,400 horses and a 400-mile range, is due to be delivered in 2022 and now has its first prototype.


It was named after a hunting dog and is equally fierce.

A global model for tackling space sustainability and safety

Posted by in categories: business, geopolitics, military, satellites, sustainability, treaties

For more than 50 years, near space has been viewed as a vast resource to exploit with few limits. In reality, near space is a very scarce resource. While international agreements such as the Outer Space Treaty and the Registration Convention take steps to protect this precious resource, no single global body is responsible for ensuring the long-term sustainability and safety of near space.

The current surge in the exploitation of outer space means that this lack of a global framework for space sustainability must be addressed immediately, or it will be too late; near space will be cluttered and unrecoverable. We are seeing increased use of near space for tourism and other business ventures and the deployment of megaconstellations comprising tens to hundreds of thousands of satellites. And this is just the start. Last month, we witnessed a Russian anti-satellite test that left portions of near space cluttered with orbital debris. Failure to implement a global framework with an enforcement mechanism for space sustainability could severely impact the ability to fully utilize the resource in the near future.

Today near space activities are subject to disparate space sustainability requirements, generally reliant on the requirements of the object’s launching state or conditions imposed by countries in which entities have market access. Some countries have developed well-crafted requirements for at least some space objects, but others have not. In addition, except for the items covered in existing treaties, like launching state liability, there is almost no harmonization on requirements, which further jeopardizes space sustainability.

Step inside a lush 2-story container home with the most shabby-chic living room ever

Posted by in categories: energy, space, sustainability

Created from five shipping containers, Debbie Glassberg’s home, constructed with the help of BNIM, is a dreamy, two-story residence that looks nothing like the containers it began life as. With two bedrooms, three bathrooms, a garden, and a patio, the home is obviously on the bigger side, but it’s such a luxurious and beautiful space that it truly deserves a tour.

Glassberg, an industrial designer who works for Mattel, wanted to create a sustainable, energy-efficient, affordable, and gorgeous home, so using shipping containers was the right idea. The planet-friendly home uses features like geothermal heating and plant foam insulation to lessen its carbon footprint. The home is drenched in color, and each room has its own feel, creating a stylish, chic setting for everyday life. From the moment you enter the home, it’s evident that someone who knows about style lives here.
