From New Atlas:
Toyota packages up a 'crate' fuel cell module you can use for
anything
Loz Blain
March 02, 2021
Fuel cells generate electricity from hydrogen, so they're a key
part of the powertrain for hydrogen-powered electric vehicles and
aircraft. But they can also be useful in a range of other
applications, and in order to promote developments outside its
own product lineup, Toyota has packaged up a fuel cell module you
can buy more or less like a crate engine, ready to plumb into
whatever device you'd like to power with hydrogen.
Toyota is heavily invested in hydrogen, as is Kia/Hyundai – a
reflection of the Japanese and Korean governments' commitments to
working towards a hydrogen energy economy. As one of the only
companies producing fuel cells at scale, it's looking to provide
a very easy way for other companies to buy and use its
technology.
Thus, it's announced its intention to manufacture "FC Modules"
that can easily be integrated into cars, trucks, buses, trains,
ships, stationary generators and any other suitable application.
Each module contains a fuel cell stack, boost converter, air
compressor, hydrogen pump and water pump, wrapped up in a spiffy
box. You'll need to supply your own hydrogen tanks, as well as
clean air and a cooling circuit. The output is a supply of
electricity, operating at a range of voltages between 400 V and
750 V, which you can route to a buffer battery or run straight
through a work circuit depending on what you're doing.
Two shapes will be available: a "vertical" unit measuring 890 x
630 x 690 mm (35 x 24.8 x 27.2 inches) and weighing about 250 kg
(551 lb), and a horizontal unit measuring 1,270 x 630 x 410 mm
(50 x 24.8 x 16.1 inches) and weighing about 240 kg (529 lb).
Each of these will be available in 60 and 80 kW versions, and
Toyota claims they all offer "world-class, top level output
density per unit volume" and "simple and infrequent" maintenance.
The modules can easily be combined to scale things up, and Toyota
is more than willing to commit engineers to help companies design
efficiently around them.

Next, the news story "Light unbound: Data limits could vanish
with new optical antennas." It is formatted in html.
When all of the text is in the receive pane, copy all of it --
including the <!DOCTYPE html> at the beginning and the </html> at
the end -- to a text editor. For this, use a text editor such as
Notepad, not a word processor.
In Fldigi, it might be easier to Select All, then Copy to the
text editor, then in the text editor delete everything before
<!DOCTYPE html> and after </html>.
Save the resulting file with any name you want, with the suffix
.htm or .hmtl. For example, swrg194.html.
Then open the file in your web browser. (For many browsers in
Windows, use Ctrl-O to do this. You could also open the file in
Windows File Explorer, and it will open in your default browser.)
You can wait until after the broadcast to do all of this.

| February 25, 2021</p><h1>Light unbound: Data limits could vanish with new
optical antennas</h1><p><em>by University of California -
Berkeley</em></p><p>Researchers at the University of California, Berkeley, have
found a new way to harness properties of light waves that can radically increase
the amount of data they carry. They demonstrated the
emission of discrete twisting laser beams from antennas made up of concentric
rings roughly equal to the diameter of a human hair, small enough to be placed
on computer chips.</p><p>The new work, reported in a paper
published Thursday, Feb. 25, in the journal Nature Physics, throws wide open the
amount of information that can be multiplexed, or simultaneously transmitted, by
a coherent light source. A common example of multiplexing
is the transmission of multiple telephone calls over a single wire, but there
had been fundamental limits to the number of coherent twisted lightwaves that
could be directly multiplexed.</p><p>"It's the first time that
lasers producing twisted light have been directly multiplexed," said study
principal investigator Boubacar Kanté, the Chenming Hu Associate Professor at UC
Berkeley's Department of Electrical Engineering and Computer
Sciences. "We've been experiencing an explosion of data in our world, and the
communication channels we have now will soon be insufficient for what we need.
The technology we are reporting overcomes current data capacity
limits through a characteristic of light called the orbital angular momentum. It
is a game-changer with applications in biological imaging, quantum cryptography,
high-capacity communications and sensors."</p><p>Kanté, who
is also a faculty scientist in the Materials Sciences Division at Lawrence
Berkeley National Laboratory (Berkeley Lab), has been continuing this work at UC
Berkeley after having started the research at UC San Diego. The
first author of the study is Babak Bahari, a former Ph.D. student in Kanté's
lab.</p><p>Kanté said that current methods of transmitting signals through
electromagnetic waves are reaching their limit. Frequency, for
example, has become saturated, which is why there are only so many stations one
can tune into on the radio. Polarization, where lightwaves are separated into
two values—horizontal or vertical—can double the amount of
information transmitted. Filmmakers take advantage of this when creating 3-D
movies, allowing viewers with specialized glasses to receive two sets of
signals—one for each eye—to create a stereoscopic effect and the
illusion of depth.</p><h2>Harnessing the potential in a vortex</h2><p>But beyond
frequency and polarization is orbital angular momentum, or OAM, a property of
light that has garnered attention from scientists because it
offers exponentially greater capacity for data transmission. One way to think
about OAM is to compare it to the vortex of a tornado.</p><p>"The vortex in
light, with its infinite degrees of freedom, can, in principle,
support an unbounded quantity of data," said Kanté. "The challenge has been
finding a way to reliably produce the infinite number of OAM beams. No one has
ever produced OAM beams of such high charges in such a compact
device before."</p><p>The researchers started with an antenna, one of the most
important components in electromagnetism and, they noted, central to ongoing 5G
and upcoming 6G technologies. The antennas in this study are
topological, which means that their essential properties are retained even when
the device is twisted or bent.</p><h2>Creating rings of light</h2><p>To make the
topological antenna, the researchers used electron-beam
lithography to etch a grid pattern onto indium gallium arsenide phosphide, a
semiconductor material, and then bonded the structure onto a surface made of
yttrium iron garnet. The researchers designed the grid to form
quantum wells in a pattern of three concentric circles—the largest about 50
microns in diameter—to trap photons. The design created conditions to support a
phenomenon known as the photonic quantum Hall effect, which
describes the movement of photons when a magnetic field is applied, forcing
light to travel in only one direction in the rings.</p><p>"People thought the
quantum Hall effect with a magnetic field could be used in
electronics but not in optics because of the weak magnetism of existing
materials at optical frequencies," said Kanté. "We are the first to show that
the quantum Hall effect does work for light."</p><p>By applying a
magnetic field perpendicular to their two-dimensional microstructure, the
researchers successfully generated three OAM laser beams traveling in circular
orbits above the surface. The study further showed that the laser
beams had quantum numbers as large as 276, referring to the number of times
light twists around its axis in one wavelength.</p><p>"Having a larger quantum
number is like having more letters to use in the alphabet," said
Kanté. "We're allowing light to expand its vocabulary. In our study, we
demonstrated this capability at telecommunication wavelengths, but in principle,
it can be adapted to other frequency bands. Even though we created
three lasers, multiplying the data rate by three, there is no limit to the
possible number of beams and data capacity."</p><p>Kanté said the next step in
his lab is to make quantum Hall rings that use electricity as power
sources.</p><div id="m"><p><strong>More information:</strong> Bahari, B., Hsu,
