Charge your MacBook Pro fast with Nomad’s new USB-C cable

Nomad’s new 100W USB-C cable allows you to charge your MacBook Pro, transfer data, and more.

Tech accessory company Nomad officially launched the newest addition to their series of cables yesterday, and it’s perfect for USB-C users who need a powerful cable with high durability.

Simply dubbed the USB C Cable – 100W, this robust accessory allows for a whopping 100W power transfer — more power than any phone or tablet requires. That means if you use it to charge any of your handheld devices, they’ll juice up as quickly as they possibly can. In addition, the Nomad USB-C supports full-speed charging for all compatible MacBooks, including the 15″ MacBook Pro that has a max charging speed of 87W.

If you routinely use your USB-C cable to transfer data, Nomad’s got you covered there, too: The 100W USB-C offers ultra-fast 10gbps USB 3.1 Gen 2 data support, and offers reinforced RF shielding for extreme data sync speeds. If you like, the cable can even handle 4K video.

Design-wise, the cable is heavy duty while remaining sleek in appearance. Its extra thick wire gauge and polyamide core is encased in a thick protective PVC jacket and then covered in braided ballistic nylon for abrasion and tear resistance. The worst part of any user-cable relationship is needing to toss it out due to strain — especially around where it connects to your device — but thankfully this USB-C cable “works reliably after 4,000 multi-directional 150 degree flexes at the lightning connector” according to the company.

The Nomad 100W USB-C cable is priced at $ 39.95, and is available for purchase on Nomad’s website. If you’re just looking for a reliable USB-C but don’t need as much power, the company also offers a thinner 60W version.

Researchers Create Device You Can Charge Just by Moving Your Fingers

Kinetic Energy Goes Electric

We have a lot of devices these days, and they all need to be charged. Though there are now pads for wireless charging, these are still plugged into a power outlet. In many cases, the charging process has barely evolved at all in the past decade or more.

But now, researchers from the University at Buffalo and the Chinese Academy of Science (CAS) might have developed the next step in this evolution, one that would no longer require plugging anything into a power socket. All it takes, according to their research recently published in the journal Nano Energy, is a special metallic tab and a little bit of body movement.

The secret is an effect called triboelectric charging, and it’s something that most people have actually seen — or felt — before. Triboelectric charging happens when a material becomes electrically charged after coming into frictional contact with another material.

Yes, that’s right. Most static electricity happens this way, like when you accidentally touch a person and you get a small jolt from it. And no, we’re not talking about an emotional jolt here, silly.

This kind of contact electrification has been quite difficult to turn into a useful power source, although there have been studies that looked into it. Too often, the materials are difficult to produce or are not cost effective. The metallic tab developed by the researchers supposedly overcomes these hurdles.

Power Through Movement

The tab features two thin layers of gold that sandwich a slab of a silicon-based polymer called polydimethylsiloxane, which is typically used in contact lenses and Silly Putty. One layer of gold is stretched and then released, causing it to crumple. Upon applying force again, movement between the layers of gold and the polymer creates friction.

“This causes electrons to flow back and forth between the gold layers. The more friction, the greater the amount of power is produced,” lead author Yun Xu, a professor of Institute of Semiconductors at CAS, said in a press release. This friction can come from the slightest movement of a finger, the researchers explained.

As a demonstration in their study, the researchers used a metallic tab that’s only 1.5 cm (0.6 inches) long and 1 cm (0.4 inches) wide. The small tab generated 124 volts, with a maximum current and density that was enough to light 48 red LED lights at the same time. Though the tech is not quite there yet, the researchers hope that their material could soon charge smartphones and other smart gadgets using just movement.

“No one likes being tethered to a power outlet or lugging around a portable charger. The human body is an abundant source of energy. We thought: ‘Why not harness it to produce our own power?’” lead author Qiaoqiang Gan, an associate professor of electrical engineering at University at Buffalo, said in the press release.

Gan and his colleagues plan to improve the performance of this triboelectric charging device while at the same time working on a portable battery that can be used to store the energy the tab generates.

Soon You’ll be Able to Dance, Clap, and Tap to Charge Your Devices

Picture the scene: a few years from now, your phone runs out of battery. Instead of scrambling for a charger, you clap your hands and watch it spring back into life.

Sound far-fetched? It’s not, thanks to a new technology developed by researchers at Clemson’s Nanomaterials Institute (CNI). In March 2017, the team put together a seemingly rudimentary device made of plastic and tape, with the unique ability to generate electricity from movements. When the two materials are brought together — by clapping hands or tapping feet — they create a voltage. And because no one can stand cables, there’s now a wireless version known as the W-TENG, which is made of a combination of teflon and a multi-part fiber containing the ultra thin material graphene.

The tile-like device has a maximum capacity of 3,000 volts. As it creates a voltage, it generates an electric field that transmits energy over a distance of up to 3 meters.

All this electricity can then be stored in batteries, but can also be used for a range of other things too. The study’s author, Sai Sunil Mallineni, names a few:

It cannot only give you energy, but you can use the electric field also as an actuated remote. For example, you can tap the W-TENG and use its electric field as a ‘button’ to open your garage door, or you could activate a security system — all without a battery, passively and wirelessly.

The team behind the W-TENG is already in talks with industrial partners to develop practical applications of the tech, and they want to make sure that when it hits the market, the magic tile is also environmentally friendly, so they are looking for an alternative to teflon.

All being well, W-TENG could streamline our capacity to charge electronic devices, and one day help reduce the burden of energy poverty in the developing world too. According to CNI director Apparao Rao, its success is a matter of ensuring that the economics of the project are as bulletproof as its scientific basis.
