Recording artist Akon has big plans for his upcoming smart city in Senegal. The new $6 billion development is called Akon City and will fulfill the star’s wish to provide a refuge for members of the African Diaspora both near and far. In addition to the 2000-acre resort, condos, and stadium, the metropolis is also planned to run on renewable energy and mainly use Akoin—the singer’s own cryptocurrency. After two years of planning and development, Akon has announced that they are breaking ground in 2021.

Akon believes that Africa, and his home of Senegal especially, is long overdue for economic investment. He is calling the forthcoming locale a “real-life Wakanda” and plans for it include a tech hub and “Senewood” to develop the film industry. Imagery by Bakri & Associates visualizes the unusual and futuristic forms that define the development and complement Akon’s forward-thinking choices.

This massive construction undertaking is geared towards stimulating the local economy and creating jobs for local workers. Many have praised this and are excited for the prospect of Akon City. But there are also some skeptics. Papa Massama Thiaw, a councilor and president of the youth commission for Ngueniene, shared that though many community members are optimistic, there is a lot of uncertainty. “The studies that were done were not in collaboration with the commune of Ngueniene,” he says. He also fears that jobs won’t be equally distributed. “I don’t want us to be just day laborers. We have to be among the managers.”

We exploit the combinatorial advantage of electrokinetics and tortuosity of a cellulose-based paper network on laboratory grade filter paper for the development of a simple, inexpensive, yet extremely robust (shows constant performance for 12 days) ‘paper-and-pencil’-based device for energy harvesting applications. We successfully achieve harvesting of a maximum output power of ∼640 pW in a single channel, while the same is significantly improved (by ∼100 times) with the use of a multichannel microfluidic array (maximum of up to 20 channels). Furthermore, we also provide theoretical insights into the observed phenomenon and show that the experimentally predicted trends agree well with our theoretical calculations. Thus, we envisage that such ultra-low cost devices may turn out to be extremely useful in energizing analytical microdevices in resource limited settings, for instance, in extreme point of care diagnostic applications.

“Power is essential to restoring wireless and wireline communications, and we are working with law enforcement to get access to our equipment and make needed repair,” the statement said. “There are serious logistical challenges to working in a disaster area and we will make measurable progress in the hours and days ahead.

We’re grateful for the work of law enforcement as they investigate this event while enabling us to restore service for our customers.

The outages were reported several hours after an explosion in downtown Nashville that took place near an AT&T facility.

We can probably all agree that charging cables are just the worst, and that we’d love to have fewer of them in our lives. Now, a new invention might give us just that: engineers have developed a flexible device that harvests energy from Wi-Fi signals.

And not just harvest. It can then convert it into electricity that could be used to power devices, wire-and battery-free.

The device is what is known as a rectenna — a portmanteau of ‘rectifying antenna’ — which is a type of antenna that converts electromagnetic energy into direct current (DC).

The companies involved used compromised software, but it’s not clear if hackers entered their networks. Finding out could be difficult.

Scientists in China claim to have built a hypersonic jet engine—called “sodramjet”—that can fly at 16 times the speed of sound. This means that an aircraft kitted out with such engines could fly anywhere in the world in two hours, according to the scientists. The test flight of a prototype was carried out in a wind tunnel in Beijing, China, and displayed excellent thrust, fuel efficiency, and operational stability. Led by Professor Zonglin Jiang of the Chinese Academy of Sciences’ Institute of Mechanics, the team’s findings were published in Chinese Journal of Aeronautics on Saturday.

Scientists in China have tested a prototype sodramjet engine in a hypersonic wind tunnel at nine times the speed of sound. Check it out here!

Can we morph cities into energy farms? We sure can now! This turbine catches wind from any direction and generates clean energy, even in dense urban areas!

There they go again. Just a few months ago the US Department of Energy tapped a startup called Group14 Technologies for a multi-million dollar R&D grant to usher in a new generation of high performance EV batteries, and now here comes Group14 with another $17 million in series B funding spearheaded by the South Korean battery expert SK Materials. If you guessed that means scaling up production for the mass market, you’re right on the money. The bigger question is why the Energy Department is determined to support the US electric vehicle industry, considering that White House policy has been aimed at supporting the US oil industry. Any guesses?

New York has among the world’s tightest rules on fire safety and regular readers of this site will be aware that that has had a big impact on the ability to site lithium-ion based battery energy storage systems (BESS) within the boundaries of the state’s urban regions.

While the development of large-scale systems is taking place in less densely populated upstate areas of New York, commercial and industrial (C&I) battery storage, which has been used elsewhere around the country to help businesses manage their energy costs and the wider network to adopt greater shares of renewables, has not really been able to gain a foothold.

A couple of weeks ago the New York Power Authority (NYPA) — a public-benefit corporation which serves around 25% of the state’s electric load — began trialling an energy storage system using lithium batteries based around start-up Cadenza Innovation’s ’Supercell’ architecture. Wrapping individual cells into a protective housing, the technology is a low-cost way to prevent thermal runaway from cascading through a battery rack and causing fires.
