This is semi-solid aluminum 3D printing! Unfortunately, according to Ric Fulop (CEO and co-founder of DesktopMetal), it can't be commercialized because the temperature control is very difficult and, when it fails, is very problematic. Nevertheless, it's an impressive demonstration.

Aluminum production with hydrogen:
-Constellium goes ahead with industrial test for Aluminum production with H2
-Lab tests in 2022 found no ill effects on energy efficiency, oxidation rate & quality
-Results available on 3Q 2024
-Al emits 3% of global emissions

A company claims to deliver green hydrogen, alumina, and heat from scrap aluminum.

H2 cost: $1/Kg

The firm is now building a commercial-scale 2MW reactor.

Oh my, what an amazing from ! 🫢️ The Composer, "premium reference headphones". But the price, like many other recent so-called headphones such as the Meze Empyrian, is way out of my league unfortunately. 🫣️ https://austrian.audio/headphones/thecomposer/

@alf My dream #headphone would be a simple construction, avoiding plastic, glue and leather in favor of #aluminum, #wood, #alcantara and if it'd make sense maybe some #carbonfiber or #fiberglass to keep it #lightweight.
Any headphone that goes in that direction is immediately targeting a very wealthy audience though. 😝️
However, I do not long for #luxury. I am looking for #practicality, #durability, #repairability, #sustainability (and admittedly a bit of #beauty too). 🫣️🤓️

The aluminium industry produces more than a billion tons of carbon dioxide annually and chemicals that warm the planet for 50,000 years. This is a paradox because aluminium is also essential for a clean energy economy, as it is used in solar panels, wind turbines and electric vehicles. The industry must reduce its emissions and pollution by switching to renewable energy, carbon capture and modern technology.

New Aluminum Radical Battery Promises More Sustainable Power
Scientists are developing the world’s first non-toxic aqueous aluminum radical battery. This new battery design, which uses water-based electrolytes, offers fire retardancy, air stability, and a potential for higher energy density than current lithium-ion batteries.
