From The Maritime Executive:

Four More Subsea Cables Disrupted Off Africa

March 14, 2024

On March 14, damage to at least four subsea cables along the west
coast of Africa slowed down internet access for a dozen
countries, according to service providers and internet traffic
analysts.

"We have determined that multiple fiber cables on the West Coast
of Africa — WACS, MainOne, SAT3, ACE — have been impacted," said
Microsoft's Azure cloud service in a statement.

The damage adds to slowdowns caused by the severing of three
cables in the Red Sea late last month. That earlier event has
been widely attributed to an anchor dragged by the stricken
bulker Rubymar, which drifted for weeks after taking a mortal hit
from a Houthi antiship missile.

Taken together, the East Africa and West Africa cable incidents
are affecting network traffic all over the continent, Microsoft
said.

The internet customers who were affected most by Thursday's
outage were residents of Liberia, who were essentially cut off,
according to Cloudflare's data. Cote d'Ivoire also experienced
substantial slowdowns, and Gambia, Guinea, Ghana, Benin, Niger
and South Africa saw lesser effects.

Internet service providers reroute traffic to alternative
networks when a subsea cable goes down, but with seven of
Africa's international data links now severed, the list of
alternative options has been reduced.

The extent, the cause and the location of Thursday's cable breaks
are still under investigation. Cloudflare reports that it has
identified a pattern in the timing of the disruptions, radiating
from north to south. Another network analysis consultancy,
Netblocks, concluded that the disruption was "likely at or near
the subsea network cable landing points."

90 percent of all international data traffic passes beneath the
sea, and securing this economically-vital infrastructure is an
increasingly important priority for Western governments. Cables
are high-value, remote, difficult to monitor, and largely
unprotected, especially in deep waters.

World's largest aircraft delivers colossal cargo to makeshift
airstrips

By Loz Blain
March 17, 2024

The 108-m (356-ft) long Radia Windrunner is designed to transport
cargo too big for the road, to short, semi-prepared airstrips on
rough terrain. It would dwarf the majestic 84-m (275-ft) long
Antonov An-225 Mriya, which is sadly no longer with us.

With the notable exception of the Large Hadron Collider, there's
really no machine in history with single parts larger than
today's mammoth wind turbines. Some offshore turbines, for
example, are being built with blades more than 140 m (459 ft)
long. One of the reasons why they're not getting to this scale on
dry land is that it's damn near impossible to move blades this
size on the road.

Corners are too tight. Bridges are too low. Even blades half that
size are a logistical nightmare – and sometimes the process is
pretty terrifying to watch, as you can see in the video below.
Wouldn't want a big gust that day!

But size really matters in wind power, where the swept area of
your turbine is the key factor in how much energy you can
harvest. The tips of the blades sweep a larger area than the
sections closest to the hub, so there's a disproportionate area
gain to be made for every bit of length you add. If onshore wind
could start using blades nearly the size of what's being used
offshore, more wind energy could be harvested at lower cost.

Thus, the idea of the Radia Windrunner – a transport solution you
could design an entire turbine manufacturing operation around,
and indeed one that wind farms would need to factor into their
plans from day dot, because it's totally focused on moving
absolutely colossal turbine blades.

If it was six feet longer, the Windrunner would stretch the
entire length of an NFL football field, and with its 80 m (261
ft) wingspan, it's nearly three-quarters the width, too. At 24 m
(79 ft) high, it's no taller than an Airbus A380 – but its
flip-top front, with the cabin elevated right up at the top of
the fuselage, allows the 108 m (354 ft) long plane to carry cargo
up to 105 m (344 ft) in length, and 7.3 m (24 ft) in diameter.

Maximum payload weight is a whopping 72,575 kg (160,000 lb),
maximum range is around the 2,000-km (1,200-mile) mark, and the
volume of the cargo bay is some 8,200 cubic m (272,000 cubic ft)
– seven times more than the mighty Antonov could offer. It'll be
rather big.

The idea is that you'd put an airstrip as close to your blade
manufacturing facility as possible, and another right there at
the location of the wind farm. You'd load a blade straight into
the plane from the factory floor, and likewise you'd crane it up
for installation pretty much straight out of the back of the
plane.

In order to facilitate this kind of behavior, the Windrunner is
designed to take off and land on a relatively short 1,800 m
(6,000 ft) airstrip. To put that into perspective, your typical,
much smaller passenger airliner typically uses a strip between
30-110% longer than that.

What's more, Radia doesn't even expect a proper paved airstrip.
Presuming that a lot of wind farms will be built in open, flat
country, it's designed the Windrunner to operate on
"semi-prepared airstrips" – that is to say, simply an area that's
been cleared of rocks, bushes, trees and other obstructions, like
what a military aircraft might land on during an operation.

According to the Wall Street Journal, the Windrunner is a lot
more than a set of renders, too – Radia has apparently raised
US$104 million to the cause, and the company estimates that the
bigger turbines it unlocks for onshore wind developers could
reduce their cost of clean energy by as much as 35%, and make
wind farms viable in a much wider range of locations. The company
apparently believes it'll have the Windrunner built, tested and
certified within around four years.

Certainly a remarkable project, and possibly one that could crack
open all kinds of opportunities for clean energy developers once
it's airborne. We look forward to following progress on this
monster machine!
