Each week, I select one article from the current issue of my newsletter Technology This Week, and post it to this blog. Today, I received a note from a representative from the VPN company Private Internet Access (PIA).
​
In his note to me, he said he’d read my article on passkeys and thought it was interesting. He continued, “Everyone online is at an ever-increasing risk of being targeted by hackers these days, which is why covering these issues is really important.”

“At PIA, we’ve also done our part to raise awareness, even producing an in-depth, four-part series on hacking that was well received. We added a helpful glossary, important infographics, and expanded statistics, plus a few safety tips for preventing cyberattacks.”

“Perhaps you would consider fitting in a link to our series in your page? We hope this will help keep more of your readers safe and well-informed – and much less vulnerable to hackers.”
So, if you want to get some well-thought-out information on hacking and Internet security, consider reading their four-part series.

One of the most plentiful elements on Earth, silicon has been used as the basis for most contemporary technology, including solar cells and computer chips. The characteristics of silicon as a semiconductor, however, are not perfect.

One reason is that while silicon allows electrons to flow easily through its structure, it is far less tolerant of "holes," which are positively charged electrons' opposites, and harnessing both is crucial for particular types of devices. Silicon also does a poor job of transporting heat, which contributes to the frequent overheating problems and pricey cooling systems in computers.

Now, research conducted by a group of scientists at MIT, the University of Houston, and other institutions has been published in Science and it shows that a substance known as cubic boron arsenide overcomes both of the negatives of silicon. It has great thermal conductivity and gives both electrons and holes high mobility. According to the experts, it is the best semiconductor material that has ever been discovered and might be the best one.
​
Until now, cubic boron arsenide has only been produced and examined in small, uneven lab batches. To examine specific small portions of the material, the researchers had to apply unique techniques that were initially created by former MIT postdoc Bai Song. If cubic boron arsenide can be produced in an efficient, practical form, much less take the place of silicon, more research will be required. However, the researchers think that soon, the material might find some applications where its special features would make a big impact.

In the decarbonization era, solar power is, by far, the leading technology both in scale and in cost. Lunar energy is taking a lot longer. One only needs to walk into the surf on the north shore of Oahu, Hawaii, to understand the enormous power in the ocean. One of the biggest differences in wave technology is the harsh and punishing environment in which this new energy generation will have to operate.

Even though it’s a tough place to extract energy, several research start-ups have tried over the past decade to harness the immense lunar power of the oceans.

Wave Swell Energy's unusual UniWave 200 is an on-shore sea platform that uses an artificial blowhole formation to create air pressure changes that drive a turbine and feed energy back to shore. In July, after a year of testing, the company reported excellent results. 

Sweden-based Eco Wave Power announced in February, that the first of 10 floats has been successfully installed on the sea wall at Jaffa Port in Israel, marking an important milestone for the company's second grid-connected wave energy harvesting project.

In late August, another startup has announced the results of a 10-year set of tests on wave energy generation. The company, Sea Wave Energy Ltd (SWEL), is making some amazing claims as to the cost and scaling of their invention—Waveline Magnet. 

In the simplest terms, the Waveline Magnet is a long, modular chain of plastic floats designed to sit on top of the water, lined up pointing directly into the waves.

These chains of floats move in a serpentine motion when waves pass through, following the movement of the water. The floats are connected by lever arms to inflexible, non-buoyant spine parts rather than directly to one another. The spine is relatively stationary while the floats move with the waves, and the lever arms move the electrical generators inside the spine units both upward and downward.

As a wave first hits the Waveline Magnet, the system gets a read on the size and speed of the wave, allowing it to fine-tune the power extraction at each generator as the wave moves down the line. SWEL says this machine can work in "all wave heights," and that "harsh wave conditions do not negatively affect the device's performance, but in contrast, enhance it, without survivability complications."

Over the past ten years, SWEL has built prototypes both in wave tanks (University of Plymouth and University of Cyprus) and also open ocean deployments. Now comes the company’s claim of energy generation volume and cost. Much of this information will have to be proven over the next year or two, but if they are right, we could be in for some revolutionary developments in the carbonless generation of energy.

The CEO of SWEL, Adam Zakheos, is quoted in a press release as saying "... we can show how a commercial-sized device using our technology will achieve a Levelized Cost of Energy (LCoE) less than 1c€(US$0.01)/kWh, crushing today's wave energy industry reference value of 85c€(US$0.84)/kWh." SWEL claims that "one single Waveline Magnet will be rated at over 100 MW in energetic environments." The company has produced a video to show how the Waveline Magnet works.

LCoE, of course, is a financial statistic that takes into account all initial capital and continuous operating costs throughout the project's duration. It would be utterly revolutionary if these devices had an LCoE of one penny per kWh (US$10/MWh). They would create power for less than half the price of solar and wind. If that LCoE is accurate, according to Lazard's statistics, it'd even outperform gas, coal, nuclear, geothermal, or pretty much any other known energy generation source.

If SWEL lives up to its promises, the world is in for nothing less than a clean energy revolution. However, there are plenty of bad-faith operators, wishful thinking, and unrealistic expectations in the market as investors line up to take part in green energy moonshots. And if the many tests conducted by SWEL had produced the kinds of results that could have predicted some of the cheapest and cleanest energy in the world, then, yeah, we'd expect to see some Gates-level investment coming in, and many more people working on projects of increasing scale.
​
So, for now, we'll remain skeptical, hoping that this is the one that surprises us, and inviting SWEL to make us eat our words as soon, and as hard as possible. We’d love this to be one of the good news stories of the 21st century.

On September 1, the USB Promoter Group announced USB4 V2.0, a specification that will double the current max speed of USB-C from 40Gbps to 80Gbps. This spec will work with existing USB-C passive cables and new 80Gbps USB-C “active cables”.

USB4 will be backwards compatible with USB4 Version 1.0, USB 3.2, USB 2.0, and Thunderbolt 3. It will also align with the latest versions of DisplayPort and PCIe.

Most home users might be perplexed as to why they've never heard of USB 4, the standard that USB 4.0 version 2.0 seeks to replace. The widely used USB 3.2 standard was intended to be doubled in performance by the August 2019 announcement of USB 4. The minimum throughput requirement for USB 4 devices is 20 Gbit/s, which is the same as the maximum throughput that USB 3.2 offers, even though the standard does permit up to 40 Gbit/s.

Although there are USB 4 cables and goods like docking stations and external hard drives available, most items still use USB 3.2 or even older standards.
​
It will be up to phone, laptop, PC and USB cable manufacturers to implement the technology. It's another win for USB-C, which Europe has decided to standardize on for all phones and gadgets.

How many people do you know who use the same password for everything and it isn’t even something hard to guess, like a birthday, anniversary, address or just “password” or “123456”? There are a lot and even with today’s excellent password managers, users have to be proactive to be sure they have rock solid passwords, change them regularly and protect them by not using them more than once.

Standards. A group of technology giants, including Apple, Google and Microsoft, have banded together to form the FIDO Alliance. This is an open industry association with a focused mission: authentication standards to help reduce the world’s over-reliance on passwords. FIDO promotes the development of, use of, and compliance with standards for authentication and device attestation. 

Apple is the first of the major players in FIDO to bring out their standards compliant solution to removing passwords from online security. The new technology is called Passkeys and will debut this fall on all of Apple’s operating systems: macOS Ventura, iOS 16, iPadOS 16, and Apple TV.

How do Passkeys Work? Passkeys are unique digital keys that are easy to use, more secure, never stored on a web server, and stay on your device. Hackers can’t steal Passkeys in a data breach or trick users into sharing them. Passkeys use Touch ID or Face ID for biometric verification, and iCloud Keychain to sync across iPhone, iPad, Mac, and Apple TV with end-to-end encryption.

When you create an online account on a website, you will use a Passkey instead of a password. “To create a Passkey, just use Touch ID or Face ID to authenticate, and you’re done,” said Darin Adler, Apple’s P of internet technologies.

When you go to log in to that website again, Passkeys allow you to prove who you are by using your biometrics rather than typing in a pass phrase (or having your password manager enter it for you). When signing in to a website on a Mac, a prompt will appear on your iPhone or iPad to verify your identity. Apple says its Passkeys will sync across your devices using iCloud’s Keychain, and the Passkeys are stored on your devices rather than on servers. (Using iCloud Keychain should also solve the problem of losing or breaking your linked devices.) Under the hood, Apple’s Passkeys are based on the Web Authentication API (Within) and are end-to-end encrypted so nobody can read them, including Apple. The system for creating Passkeys uses public-private key authentication to prove you are who you say you are.

A password-less system would be a significant step forward for most people’s online security. As well as eliminating guessable passwords, removing passwords reduces the likelihood of successful phishing attacks. And passwords can’t be stolen in data breaches if they don't exist in the first place. (Some apps and websites already allow people to log in using their fingerprints or using face recognition, but these usually require you to first create an account with a password.)
​
When all the tech companies have rolled out their version of passkeys, it should be possible for the system to work across different devices—in theory, you could use your iPhone to log in to a Windows laptop, or an Android tablet to log in to a website in Microsoft’s Edge Browser. “All of FIDO’s specs have been developed collaboratively, with inputs from hundreds of companies,” says Andrew Shikiar, the executive director of the FIDO Alliance. Shikiar confirms Apple is the first company to roll out passkey-style technology and says this shows “how tangible this approach will soon be for consumers worldwide.”
