From New Atlas:

Kilometer-tall skyscrapers to double as massive batteries

By Adam Williams
June 04, 2024

Skidmore, Owings & Merrill (SOM), the designer of the world's
tallest building, Dubai's Burj Khalifa, has joined forces with
Energy Vault Holdings to investigate the possibility of creating
something even taller: huge 1-km [3,280-ft]-tall skyscrapers that
would also function as gigantic gravity based energy storage
systems.

The proposal features two particularly notable ideas. The first
brings to mind research from the likes of Gravitricity and IISA,
and would use excess energy – whether from renewable sources like
solar or from a standard power grid – to raise a weight up to the
top of a very tall skyscraper. When required, the weight is then
released, allowing it to descend to the bottom of the building,
harnessing the force of gravity to drive a generator.

"EVu is a superstructure tower design, which improves unit
economics and enables GESS [gravity energy storage systems]
integration into tall buildings through the use of a hollowed
structure with heights over 300 meters [roughly 984 ft], and up
to 1,000 meters [3,280 ft] tall," explains the press release by
SOM and Energy Vault Holdings. "These structures will have the
capacity to reach multi-GWh of gravity based energy storage to
power not only the building itself but also adjacent buildings'
energy needs. This innovative design which integrates leading
GESS technology within superstructure building design and
engineering will, for the first time in building construction and
operation history, enable a carbon payback within accelerated
timeframes of 3-4 years."

Alongside the EVu gravity system above, the team also proposes
the so-called EVc system. This would function similarly but
instead of a large weight, it would pump water to the top of the
skyscraper then drop it to run turbines and produce power.

Though it might sound futuristic, we do already have quite a lot
of similar systems in place for pumped-storage hydroelectric
power stations. Water is released from a mountain or hill for
example, generating electricity by spinning turbines as it flows
downhill and providing more electricity when it's needed. When
excess juice is again available, the water is pumped back up to
the top, ready to start the process again.

Though the basic science behind both ideas is sound, the
practical challenges are considerable, and include issues like
being able to support all that extra weight, plus efficiency and
general maintenance. Perhaps the largest stumbling blocks are the
most tedious though: the amount of space it would take up plus
all the moving parts could make building an office or residential
skyscraper with this system simply economically unfeasible.

Take this one with a pinch of salt for now, then. However, there
is some serious talent behind the collaboration, including Bill
Baker, who co-created the Burj Khalifa, so we'll be interested to
see if it goes anywhere.

From the Voice of America:

On Alaska's remote southeast coastline, radio keeps communities
connected

By Maya Jimenez
June 3, 2024

In the remote and rural communities of southeastern Alaska, news
is never in short supply thanks to a small but dedicated crew of
journalists.

"We are what we call community radio," said Angela Denning. The
radio journalist is the regional news director of the media
nonprofit CoastAlaska and oversees six newsrooms.

All of them, she said, are "pretty darn remote."

Just one person runs the newsroom in Wrangell — an island borough
of little more than 2,000 people on the Alaska panhandle — while
two people run the newsroom that Denning oversees in Petersburg,
another panhandle town.

"It has 3,300 people. It's on an island, so no roads in or out.
We take planes, we take boats," she told VOA.

Denning says their audiences rely on stations like hers for news
and natural disaster warnings. But radio also provides a human
connection that is harder to achieve through websites.

"It's very personal," said Denning, adding that listeners often
tune in for updates on middle school basketball games, or just to
hear the voices of their neighbors, friends or colleagues.

That personal connection serves them well as CoastAlaska teams up
with media nonprofits working to prevent the spread of
disinformation.

Communities where agriculture, logging or mining are the main
industries are seeing a growth in misinformation and
disinformation, media groups say. To stem that, organizations
like the Rural News Network and the News Literacy Project work
with affiliates, including CoastAlaska, to offer audiences the
tools to spot and debunk false information.

Local media are often on the front line of fighting
disinformation, said Mike Webb, the News Literacy Project's
senior vice president of communications.

As the U.S. prepares for elections, his nonpartisan group is
helping newsrooms like Denning's to equip audiences with the
tools they need to spot misinformation.

Ten years ago in Alaska, Denning said, misinformation and
distrust in media were less of a worry.

"Trust. It was something we took for granted," she said. But now,
"we don't assume there's trust anymore. Quite the opposite."

To build and preserve trust, CoastAlaska works with its community
to help audiences feel more involved. They have changed the
formats of public forums to allow more engagement and to receive
feedback from their audiences.

For instance, when residents felt as if they didn't have a voice
in a local election, the journalists set up a way for audiences
to ask questions at a borough assembly candidates forum.

For the first half, the media asked questions. Then they let
residents quiz the candidates.

"We pulled their names out of the hat during the program so that
those people would be able to ask the questions," Denning said.
And people had to ask their question to all the candidates, not
just one.

It was one way for some people who are suspicious of or don't
have much trust in media outlets to feel like they were empowered
and part of the process.

"I think it kind of worked," she said. "We got good feedback
about it. But of course, we approached it very carefully."

Part of CoastAlaska's success is its existing connections with
the audience.

"I think it works because we are covering community-based local
events such as who's going to tell the community how the high
school did at their basketball game over the weekend. That's us,"
Denning said.

In her region, the most engagement their reporting receives is
often on the successes of students or community member profiles,
Denning said. Though, she added, the reporters also cover issues
like landslides, conflicts with the logging industry, and
economic problems.

"Our listeners and readers may not agree with everything we say
but they also really appreciate the coverage that we give to the
community, all those little things," she said.

Despite being largely isolated on islands in the state's
southeast, Denning's reporters are always talking with each
other.

"If you're in constant contact with your colleagues, even if
they're a few hundred miles away on a different island, you can
still feel supported," Denning said. "During this time of
misinformation and distrust, that's more important than ever."

Hallo zusammen,

hier ein Test mit einer verrauschten Sprachübertragung (2182 kHz) und zwei unterschiedliche "Filtered" aus der KI.

Drei MP3-Dateien:

- Einstellung Original    2182_kHz_240202_193930_Original.mp3
- Einstellung 0,70        2182_kHz_240203051221_Filtered_0_70-N.mp3
- Einstellung 1,00        2182_kHz_240203050920_Filtered_1_00-N.mp3

Man kann nach seinem Gehörgeschmack die Ausgabe beeinflussen. Die "Max audio buffer (default 200 ms) hatte bei mir keinen Einfluss auf die Qualität.
Die Unterschiede können am besten mit einem Kopfhörer wahrgenommen werden.
 

Ein weiterer Test:        German_Airforce_Original-N.mp3

                          German_Airforce_KI_RM-N.mp3

Einige OMs haben auch bereits in YouTube ihre Tests präsentiert - einfach "RM-Noise" eingeben.

73, Josef
DE3JGA
 

[-N bedeutet:  Die MP3-Dateien wurden non-destruktiv normalisiert - d.h. der Gain der MP3-frames wurde erhöht. "German_Airforce_KI_RM.mp3" hatte z.B. nur -37 dB  /roger]
