We’ll need thousands of these direct air capture plants or their equivalents from industry and nature to reduce atmospheric CO₂.

Direct Air Capture, also known as DAC, is one of a number of carbon capture technologies seen as a way to mitigate the worst impacts of global warming. The technology harvests carbon dioxide (CO₂) from ambient air. It is not an add-on to a coal-fired or natural-gas thermal power plant, but rather a standalone solution to removing CO₂ from the atmosphere for the purpose of permanently sequestering it underground.

A leader in this form of carbon capture and sequestration (CCS) is Carbon Engineering, a Canadian-based company whose demonstration plant sits in Squamish, British Columbia. Bill Gates is an investor. And now Occidental Petroleum through its subsidiary 1PointFive has entered into a partnership to build and deploy a minimum of 70 or as many as 135 DAC plants like the one seen in the picture above by 2035.

Jackson, Michigan-based Sesame Solar is today unveiling what it claims is the world’s first fully renewable mobile nanogrid – that’s a small microgrid – that runs on solar and green hydrogen.

The nanogrid’s solar array is electronically unfolded, and it’s ready to start generating power within 15 minutes. The company claims it can be set up by a single person.

New Zealand is introducing a flatulence tax on livestock farmers in an effort to reduce methane emissions.

Livestock is the country’s largest source of methane emissions. As a result, the government is introducing a tax to change farm practices.

Researchers at Imperial College London have developed a new dual drone that can both fly through air and land on water to collect samples and monitor water quality. The researchers developed a drone to make monitoring drones faster and more versatile in aquatic environments.

The ‘dual robot’ drone, tested at Empa and the aquatic research institute Eawag in Switzerland, has successfully measured water in lakes for signs of microorganisms and algal blooms, which can pose hazards to human health, and could in the future be used to monitor climate clues like temperature changes in Arctic seas.

Hong Kong, a densely populated city where agriculture space is limited, is almost totally dependent on the outside world for its food supply. More than 90% of the skyscraper-studded city’s food, especially fresh produce like vegetables, is imported, mostly from mainland China. “During the pandemic, we all noticed that the productivity of locally grown vegetables is very low,” says Gordon Tam, cofounder and CEO of vertical farming company Farm66 in Hong Kong. “The social impact was huge.”

Tam estimates that only about 1.5% of vegetables in the city are locally produced. But he believes vertical farms like Farm66, with the help of modern technologies, such as IoT sensors, LED lights and robots, can bolster Hong Kong’s local food production—and export its know-how to other cities. “Vertical farming is a good solution because vegetables can be planted in cities,” says Tam in an interview at the company’s vertical farm in an industrial estate. “We can grow vegetables ourselves so that we don’t have to rely on imports.”

Tam says he started Farm66 in 2013 with his cofounder Billy Lam, who is COO of the company, as a high-tech vertical farming pioneer in Hong Kong. “Our company was the first to use energy-saving LED lighting and wavelength technologies in a farm,” he says. “We found out that different colors on the light spectrum help plants grow in different ways. This was our technological breakthrough.” For example, red LED light will make the stems grow faster, while blue LED light encourages plants to grow larger leaves.

German industrial manufacturer Covestro aims to develop software with QC Ware that would use quantum computing to create more efficient chemical reactions and better materials.

Everything is about to be illuminated.

A team of researchers from Imperial College London and Newcastle University has just observed what happens after light strikes solar cells.

Imagine a more sustainable future, where cellphones, smartwatches, and other wearable devices don’t have to be shelved or discarded for a newer model. Instead, they could be upgraded with the latest sensors and processors that would snap onto a device’s internal chip—like LEGO bricks incorporated into an existing build. Such reconfigurable chipware could keep devices up to date while reducing our electronic waste.

Now MIT engineers have taken a step toward that modular vision with a LEGO-like design for a stackable, reconfigurable artificial intelligence chip.

The design comprises alternating layers of sensing and processing elements, along with light-emitting diodes (LED) that allow for the chip’s layers to communicate optically. Other modular chip designs employ conventional wiring to relay signals between layers. Such intricate connections are difficult if not impossible to sever and rewire, making such stackable designs not reconfigurable.
