Clever Device Generates Electricity From Thin Air – Futurism

Published

Thin Air

A team of scientists at the University of Massachusetts Amherst have come up with a clever device they dubbed the “air-gen,” which can generate electricity from moisture found in air. According to the team, their discovery could revolutionize green energy by offering some key advantages over other renewable source including sun or wind energy.

“We are literally making electricity out of thin air,” electrical engineer Jun Yao, co-author of the paper appearing in the journal Nature today, said in a statement. “The Air-gen generates clean energy 24/7.”

Geobacter

A naturally occurring microbe called Geobacter produces electrically conductive protein nanowires. By tapping these nanowires using electrodes, the device can effectively generate an electrical current from moisture — enough to power small electronics in its current form.

The scientists suspect the charge is caused by protons diffusing along the nanowires, as noted in their paper.

“A maintained moisture gradient, which is fundamentally different to anything seen in previous systems, explains the continuous voltage output from our nanowire device,” they wrote.

Patch Day

But before scaling up their current design, the team is planning to develop small air-gen “patches” that can power wearable devices or smartphones.

“The ultimate goal is to make large-scale systems,” Yao said in the statement. “For example, the technology might be incorporated into wall paint that could help power your home. Or, we may develop stand-alone air-powered generators that supply electricity off the grid.”

Payments tech company Lightspeed Commerce conducting strategic review of business

Published

 on

 

MONTREAL – Lightspeed Commerce Inc. says it is conducting a review of its business and operations including talks relating to a range of potential strategic alternatives.

The Montreal-based payments technology company made the comments after reports concerning a potential transaction involving the company.

Lightspeed says it periodically undertakes a review of its business and operations with a view of realizing its full potential.

A strategic review is often seen by investors as a prelude to a sale by a company.

Lightspeed says its board of directors is committed to acting in the best interests of the company and its stakeholders.

Company founder Dax Dasilva returned to the role of chief executive officer earlier this year and has been working to return the company to profitability.

Bank of Canada trying to figure out how AI might affect inflation, Macklem says

Published

OTTAWA – Bank of Canada governor Tiff Macklem says there is a lot of uncertainty around how artificial intelligence could affect the economy moving forward, including the labour market and price growth.

In a speech in Toronto at the Economics of Artificial Intelligence Conference, the governor said Friday that the central bank is approaching the issue cautiously to get a better understanding of how AI could affect its job of keeping inflation low and stable.

“Be wary of anyone who claims to know where AI will take us. There is too much uncertainty to be confident,” Macklem said in prepared remarks.

“We don’t know how quickly AI will continue to advance. And we don’t know the timing and extent of its economic and social impacts.”

The governor said AI has the potential of increasing labour productivity, which would raise living standards and grow the economy without boosting inflation.

In the short-term, he said investment in AI is adding to demand and could be inflationary.

However, Macklem also highlighted more pessimistic scenarios, where AI could destroy more jobs than it creates or lead to less competition rather than more.

The governor called on academics and businesses to work together to shed more light on the potential effects of AI on the economy.

“When you enter a dark room, you don’t go charging in. You cautiously feel your way around. And you try to find the light switch. That is what we are doing. What we central bankers need is more light,” he said.

United Airlines will offer free internet on flights using service from Elon Musk’s SpaceX

Published

CHICAGO (AP) — United Airlines has struck a deal with Elon Musk’s SpaceX to offer satellite-based Starlink WiFi service on flights within the next several years.

The airline said Friday the service will be free to passengers.

United said it will begin testing the service early next year and begin offering it on some flights by later in 2025.

Financial details of the deal were not disclosed.

The announcement comes as airlines rush to offer more amenities as a way to stand out when passengers pick a carrier for a trip. United’s goal is to make sitting on a plane pretty much like being on the ground when it comes to browsing the internet, streaming entertainment and playing games.

“Everything you can do on the ground, you’ll soon be able to do on board a United plane at 35,000 feet, just about anywhere in the world,” CEO Scott Kirby said in announcing the deal.

The airline says Starlink will allow passengers to get internet access even over oceans and polar regions where traditional cell or Wi-Fi signals may be weak or missing.
