Net Work
Alan Winstanley
This month, our Net Work column muses over the impact that artificial intelligence (AI) is
having, provides more practical tips for safeguarding online security and protecting data,
and provides more news from the space race and the faltering EV market.
T
he most overused buzzword in
technology today must be ‘AI’; it
seems that every aspect of our lives
is becoming ‘AI-enabled’. IBM defines
artificial intelligence as “technology
that enables computers and machines to
simulate human intelligence and problemsolving capabilities”.
I’ve heard many a disaffected worker
say, “I’m not paid to think”, but artificial intelligence systems are actually
‘dumb’ in the sense that they simply do
the job they’re designed to do. However,
they can also be designed to ‘learn’ and
refine their ‘thinking’ as they go along.
AI-enabled systems can relieve humans of onerous or potentially dangerous tasks, reduce human errors, vastly
increase productivity, or just fob off customers and their tiresome enquiries because not enough human operators are
available to answer the phone.
The near-human-like machine performance we encounter daily is fast becoming normalised and accepted by everyday users as though AI really is, well,
human. Instead of searching Help files
or User Guide PDFs, Windows Copilot, now being introduced in Windows
11 updates, sees Microsoft’s next iteration of AI being embedded to help users
manage their computers in a far more
human-like way.
If I ask Bing Copilot to define, say, medieval etymology using a comic style,
the machine results are now indistinguishable from human work: “So next
time you’re at a Renaissance fair, impress your friends with this tidbit: ‘Did
you know “medieval” is just fancy talk
for “middle age”? Pass me another turkey leg, good sir!’”.
More mundane tasks, such as summarising real-life Amazon product reviews for buyers, analysing – not always
correctly – dodgy Facebook posts, or
describing items for sale on eBay, have
fallen under the spell of AI-powered
‘bots as well.
So-called ‘generative’ artificial intelligence (GenAI) goes further by using advanced routines, machine learning and algorithms to create pseudo-authoritative,
real-time responses to our queries, online search terms or smart-speaker
commands. This is seriously affecting
regular news channels, whose online
content is being scraped wholesale by
GenAI ‘bots looking to re-publish the
latest news for themselves.
In turn, local news journalism and
news-gathering are suffering from a
triple-whammy: competing against generative news content scraped online,
social media (worryingly, people really
do turn to TikTok for their ‘news’) and
the slump in traditional advertising
revenue.

customers. It had mixed thoughts about this smoking mainspowered USB charger! (Source: Amazon UK)

Flaming hot dogs
Enormous advances in technology,
electronics, mechatronics and coding
are also making AI-powered robots and
drones a reality. China has reportedly
produced squads of robotic quadrupeds
that could be armed with rifles, while
in contrast, the American-made ‘Thermonator’ quadruped packs a handy
flamethrower that is said to be legal in
most USA states but probably nowhere
else. You can see them in action on YouTube at https://youtu.be/xEVwkzAcqOQ
These ‘robo-dogs’ doubtless have
many potential peace-time roles, but I
guess it’s only a matter of time before
autonomous machines like these could
operate in swarms under combat conditions. There’s a cheery thought!
‘Kamikaze drones’ are already being used in combat by Ukraine, with
AI-powered seekers that allow them to
guide themselves to a target their operator selects, even if their comms are
jammed or lost (https://pemag.au/link/
abyh). How long before an AI-equipped
drone can simply be unleashed to ‘seek
and destroy’?
The darker side of AI is seen in the
production of deepfake videos or, as I
found out myself, the pirating and recopying of textbooks under other titles
to cash in on the original work (see Net
Work, May 2024).
It is still going on now; you can search
Amazon for niche subjects such as
A cross-haired terror: China’s PLA is developing armed
quadrupeds that are not exactly cute or house-trained.
(Youtube/<at>carrosshow9598)
Practical Electronics | September | 2024
The US-made Thermonator is the world’s first flame-throwing robot quadruped, intended
for agriculture, ice clearing and similar uses. Any similarity to the word “Terminator” is
purely coincidental! (https://throwflame.com)
“Master R Programming” or “DIY Lithium Batteries Handbook”, for example,
to see a wide variety of similar book
covers complete with pseudonyms. You
would never know they were all generated by AI before being polished off and
uploaded using cheap labour. Established authors are also suffering from
the curse of foreign AI-generated books
being published using their names.
All this AI-enabled computing needs
far more ‘juice’, and new data centres
are needed to provide the raw data processing power, such as the proposed
185-acre AI data site mentioned in July’s
Net Work, destined to be one of Europe’s
largest.
The personal computer industry is
also eagerly cashing in on the AI wave,
with the latest tranche of ‘AI PCs’, designed to give Windows Copilot and
AI-based apps more headroom to play
with. Hence, the term NPU (Neural
Processing Unit) now appearing in PC
sales blurbs; an integrated processor optimised for data-driven AI-related tasks.
A blog entry by computer maker Dell
reckons that “the advances from Generative AI will compare to the PC’s introduction 40 years ago, which brought
unseen levels of productivity to the
world… This [AI] will require you to reimagine how you work with the familiar
laptop and desktop of today”.
Dell foresees new ways of interacting
with technology, including using voice,
gestures or visual commands, stating,
“Your PC experience will transition
from searching to prompting, from reading to understanding, from editing to
directing.” The days of pressing F1 for
Help are fast disappearing, and AIs like
Copilot will do more of the thinking and
heavy lifting for you.
The idea of Two-Factor Authentication (2FA) to send a One-Time Password
(OTP) to a mobile phone is intended to
enhance security. In a scam known as
‘SIM swapping’, fraudsters try to transfer the victim’s mobile phone number to
another phone to intercept those OneTime Passwords. Network operators
have been working hard to overcome
this, and London’s Metropolitan Police
offers some basic advice (PDF) for users
at https://pemag.au/link/abyi
Some users dedicate a second mobile phone to receiving 2FA texts rather
than using their main one with a widely
known number, but the consensus is
that using a physical hardware key or
an authentication app with biometrics
is far more secure than relying on 2FA.
Last month, I showed some USB security keys made by Yubico, and the independent Techradar website recently
reviewed several software apps and
recommendations, including Authenticator by 2Stable, NordPass and Authy,
with Google Authenticator classed as a
basic, free app. You can learn more at
https://www.techradar.com/best/bestauthenticator-apps
Last month’s column discussed many
security-related concerns that can affect
everyday Internet users. I wrote that
using passwords to log into websites is
becoming increasingly insecure, mainly due to the risk of them falling into
the wrong hands or being too easy to
guess.
I recently noted how even the UK’s
National Lottery website, with a EuroMillions rollover prize of some £130
million (€153 million or AUD 247 million!) at stake last month, simply needs

Space News
This month’s news of the space race
starts with China’s success in returning
two kilograms of soil samples from the
far side of the moon, a world first. A
YouTube video documentary at https://
youtu.be/cTqvz7Qtd2o (there are others available) showcased the ‘unboxing’ of the returned capsule.
China has offered to share samples
with the international scientific community, but America’s Wolf Amendment legislation raises questions over
whether NASA can cooperate with
China this way. Apollo’s manned moon
missions obtained a total of 382kg of
moon soil and rocks, starting in 1969
when Apollo 11 returned 21.5kg to
Earth, the first soil collected from any
celestial body. You can take a virtual
tour of NASA’s sample lab at https://
curator.jsc.nasa.gov/lunar/index.cfm
The spacenews.com website points
to China’s recent application to create
a 10,000 satellite constellation called
HONGHU-3. China is also investing heavily in SpaceX-style re-usable
rocket launches; a carrier rocket successfully completed a 10km VTOL
flight test in northwest China in early July, and a larger version is set to
launch in 2025.
Earlier, a ground test of a privately
produced Tianlong-3 VTOL rocket
went awry when the rocket broke away
from its moorings and launched into
the air before crashing again in a huge
fireball (shown in the BBC video at
https://pemag.au/link/abyl).
The direction of travel (into orbit) is

clear; coupled with several earlier mysterious satellite launches, there are major concerns that China is constructing
an advanced surveillance network that
could eventually track and take highresolution photos or videos of anything
in the Indo-Pacific region.
Meanwhile, Boeing’s maiden voyage
of the Starliner crew capsule is now
into extra time. The June 5th launch
to the ISS was intended to last about a
week, but problems with thrusters and
minor helium leaks are causing flight
engineers to cautiously extend the mission to 45 or even 90 days onboard the
ISS while risks are assessed. There are
no reports of any other problems, including with power or food.
Four years ago in Net Work, June
2020, I reported on the Grumman Mission Extension Vehicle (MEV), a space
tow truck that can physically dock with
orbiting satellites running low on fuel
to extend their working life. The vehicle is compatible with 80% of orbiting
geostationary satellites.
Grumman has plans for a nextgeneration space breakdown truck:
a proposed Mission Robotic Vehicle
(MRV) will use a robotic arm to dock
with a client’s spacecraft, providing
robotic inspection, relocation, repair,
debris removal and filling up. Mission Extension Pods (MEPs) could
also be applied to extend life up to
six more years. How Grumman expects the in-flight refuelling service
to work is shown at https://youtu.be/

EVs: static electricity
Recently, I saw a BYD electric car
making its way silently through my
rural village, a sure sign that the Chinese EV onslaught is edging ever closer. The EV market continues to falter,
though, as high purchase prices, poor
residuals, the usual worries about
range anxiety and a patchy charging
network dampen demand for these expensive new vehicles. Remember that
the UK has even failed so far to roll
out a dependable national smart meter
network!
The bulk of EV sales now go to fleet
buyers. Owners also face intense insurance and repair problems, and trade
wars may yet break out with US and
EU tariffs threatening to curb demand
even more.
In January 2022, I featured the GWM
Ora, a cute, chic-looking EV made by
China’s Great Wall Motors that was undergoing type approval for UK sales. So
far this year, fewer than 900 Ora cars
(0.9% of all YTD sales) have been sold
in Britain, and Great Wall is now closing its European HQ in Munich at the
end of August due to poor sales.
The EV market’s woes don’t end
there. After managing just 259 UK sales
of their £36,000 cars, Fisker, an EV
start-up whose stylish ‘Fisker Ocean’
came with ‘green’ credentials (see Net
Work, May 2022), has filed for bankruptcy. Bloomberg reports on the sorry
tale at https://pemag.au/link/abym
Perhaps that same Net Work column
was jinxed, as the promising ZipCharge
Go ‘powerbank for EVs’ that I also
showed never got beyond the prototype
stage, nor was there any sign of electric
trucks being trialled on my local motorway either.
There’s some better news from Britain’s electricity generation network.
The Electricity System Operator (ESO)
expects it will have more ‘headroom’
to cope with contingencies this coming
winter compared with last year.
The role of Demand-Side Response
11
is to balance electricity supply with demand, and the ‘Demand
Flexibility Service’ was created urgently following the Ukraine
energy crisis to incentivise consumers by offering them a modest
cash inducement to reduce their power usage.
It worked; during the crucial winter period of 2022/23, 1.6
million households and businesses participated in the service
by shifting demand, saving over 3300MWh of electricity, says
the ESO, and in winter 2023/24, 2.6 million users saved over
3700MWh.
The ESO has now confirmed there will be no need for the Demand Flexibility Service during the coming winter 2024/25 period. Still, they intend to develop the concept as a commercial
service throughout the coming year and encourage users to habitually economise as a matter of course.
The energy providers are also incorporating state-of-the-art battery energy storage systems (BESS) into their networks to provide
backup energy sourced from renewables. One example is Tesla’s
Megapack, which offers pre-manufactured 3.9MWh battery packs
off-the-shelf.
These are already being used in Europe’s largest battery storage
farm in Cottingham, England, a project that has reportedly taken
seven years to complete. Other redundant sites are also being given over to battery farms.
If we think we have problems in the UK with planning permission, Australia’s Victorian Government commissioned a Tesla
BESS farm for its Victorian Big Battery (VBB), treading carefully
on hallowed ground to respect the Wadawurrung people, traditional owners of the land on which VBB operates, they are at
pains to acknowledge.
During commissioning in July 2021, a liquid coolant leak
caused electrical arcing, with one of the battery packs ‘failing
safe’ after catching fire. As regular Net Work readers will know,
Li-Ion batteries can thermally run away and cannot readily be
extinguished. So, Tesla’s advice was to let it burn itself out over
six hours, which it did, incident reports state. Normal operation
was then resumed.

That’s all for this month. From the next issue, I’ll be at the
wheel of a shorter Net Work (steering?) column, as after 28 years
and half a million words, I’m easing off the accelerator in the
