Talking about the future with a partner or a potential partner might 
feel scary, but if we aren’t communicating, we’re projecting. Don’t we 
owe ourselves the intimacy of something more? I see now that it was not 
only conversations about our planet’s future that I struggled to have 
with my ex, it was conversations about our own future, too. It can be 
easy to feel as if the question of whether to have children, like rising 
sea levels, will be dealt with down the road.

But the future, as with the sea, does not obey its supposed bounds. If 
being alive right now sometimes feels like standing on a cliff, I want 
to be with someone who’s not afraid to peer at the frothing tides. Not 
because I need to solve anything, but because I don’t want a 
relationship built on looking away.

“I feel safer when I’m in love,” a friend recently told me. And at these 
times when our future feels most uncertain, romantic relationships are 
not just distractions, they’re places for nourishment, bolstering us to 
face what’s outside the door.

*Supercapacitor cement could supercharge renewable energy storage*
BY TIM WOGAN
AUGUST 7, 2023

Production of cement and concrete is today responsible for approximately 
8% of global carbon dioxide emissions. Several ideas to reduce this by 
using alternative cement formulations, for example, have yet to achieve 
widespread success. Meanwhile, rising investment in intermittent 
renewable energy sources has led to rising demand for storage 
technologies. ‘Batteries are based on rare materials that are not 
available to everyone, so it’s not scalable,’ says Franz-Josef Ulm of 
the Massachusetts Institute of Technology. Ulm and colleagues devised a 
bipartite solution by adding new functionality to concrete, allowing it 
to be used as a ‘structural capacitor’.

The researchers simply add nanoparticles of carbon black to cement 
paste. Being hydrophobic, these initially stay isolated in the 
water-rich environment. As the cement cures, however, the hydrophilic 
calcium silicates form calcium silicate hydrates and calcium hydroxide, 
removing free water from the system. The carbon nanoparticles then 
self-organise into an extremely long conductive network permeating the 
cement. By soaking the cement in potassium hydroxide, the researchers 
allow ions to diffuse in and out of the pores. Connecting the electrode 
to a positive charge causes the conductive network to attract negative 
ions and repel positive ions and the reverse when it is connected to a 
negative charge. Separating two of these saturated cement slabs by a 
dielectric membrane therefore allows a potential difference to build up 
and energy to be stored.

The researchers used small charged cement supercapacitors to power a 3V 
LED, and now hope to move to large-scale, real-world applications. The 
charge/discharge rate is limited by the porosity of the cement, but this 
shouldn’t be a problem in building foundations that can store solar 
energy, for example. ‘You have the whole day to charge the 
supercapacitors and then overnight…you use it to run whatever type of 
energy load you need for the home,’ Ulm says.

The researchers showed that they could also increase the porosity of the 
cured cement by adding extra water during its production. This allows 
for faster charge/discharge cycling, which could open up applications 
such as roads that charge passing electric vehicles by electromagnetic 
induction, although it does compromise the strength of the concrete. 
‘For each application there will be different requirements we need to 
fulfil,’ says co-author Admir Masic. ‘The essential point our paper is 
making is the accessibility of our material anywhere in the world for 
everyone. I honestly expect this material to permeate our society in an 
unprecedented manner simply because it is two inexpensive materials that 
we know how to process.’

Deborah Chung at the University of Buffalo in New York is skeptical, 
however. ‘In the abstract they claim high strength, but in the paper 
there is no measurement of the strength,’ she says. The researchers rely 
on hardness measurements from nano-identation, and Ulm says he has 
‘built a career showing the link between hardness and strength’ but 
Chung remains unconvinced and says that this ‘is not an adequately 
recognised mechanical property indicator in the concrete field’. ‘The 
high porosity is bound to cause fragility… I’m positive that the 
material that they are calling a structural electrode is actually a 
fragile material,’ she concludes.

Bernhard Pichler at Vienna University of Technology in Austria, however, 
does not dispute the strength measurements, and says that ‘the authors 
have used an initial water-to-cement mass ratio of 0.42. This allows you 
to produce regular-strength concrete. In many practical applications, 
even larger ratios are used… Lower ratios are needed to produce 
ultra-high performance concretes, but they are used for rather special 
applications only. Overall, I think this paper is extremely interesting, 
and it will be influential in my scientific community for sure.’

*Scientists concerned 'rare' glacial flooding event in Alaska could 
happen again*
The sheer force of Mother Nature was on full display, researchers said.
By Julia Jacobo
August 7, 2023
Astonished scientists could not have predicted the severity of a glacial 
lake outburst flood that inundated a large portion of Juneau, Alaska, 
over the weekend.

Now, they're worried the unprecedented event could happen again.

City officials in Juneau, Alaska, issued an emergency declaration Sunday 
after a glacier lake outburst flood, from the Suicide Basin on the 
Mendenhall Glacier, wreaked havoc in the city.
- -
*How rare was the flooding event from the Mendenhall Glacier*
When the Federal Emergency Management Agency created flood maps for the 
Mendenhall Glacier, it defined a 100-year flooding event as discharge of 
17,000 cubic feet per second, and a 500-year flooding event as discharge 
of 20,000 cubic feet per second, Jacobs said.

The flooding that occurred on Saturday night was the result of a 
discharge event of about 25,000 cubic feet per second, which FEMA had 
previously determined had less than 1% chance of occurring, Jacobs said.

"We couldn't imagine this amount of water coming out so fast," Jacobs 
said...
- -
*What led to the glacier lake outburst flood*
A glacial lake outburst flood occurs when a dam containing a glacial 
lake breaks. But Mendenhall Glacier actually gets lifted up from 
pressure building within the basin. So when the glacier is great enough 
to lift the glacier, the water escapes the basin and flows downstream, 
Jacobs said.

The basin fills in the summertime from snow melt and rainfall. The 
Suicide Glacier, which used to feed into the Suicide Basin, still hangs 
over it, so the melting from that ice contributes to water levels in the 
basin as well, Jacobs said...
- -
*How researchers predict outburst floods from Mendenhall Glacier*
Those in charge of monitoring the Mendenhall Glacier and the lakes 
within it can tell when a flooding event is gearing up, Jacobs said.

The National Weather Service in Juneau has a "well-versed" monitoring 
program, which involves elevation marks on Suicide Basin and a camera 
pointed it its direction, in order to see how much the water levels are 
falling and rising...
- -
*Concerning flooding from the ***Mendenhall Glacier* has been happening 
for over a decade*
Suicide Basin has been releasing glacier lake outburst floods that cause 
inundation along Mendenhall Lake and Mendenhall River since 2011, 
according to the National Weather Service.
