Nasa invents "revolutionary" material 1,000 times better than state-of-the art spaceship alloys

Quote:
The material has twice the strength, three-and-a-half times the flexibility and more than 1,000 times the durability under stress at high temperatures.
How far away is Unobtainium and how long until I can purchase aftermarket parts made from it?

NASA Alloy GRX-810, an oxide dispersion strengthened (ODS) alloy, can reportedly endure temperatures over 1093C, is more malleable, and can survive more than 1,000 times longer than existing alloys.
[snip]
The team applied thermodynamic modelling and leveraged Additive Manufacturing to develop the new high-temperature alloy. Using thermodynamic modelling, one of many computational tools discussed within the NASA 2040 Vision Study, the team discovered the optimal alloy composition after only thirty simulations.

The search to find this was interesting in itself: www.youtube.com/results?search_query=rectenna

Apparently 100% efficient solar cells are possible if you treat light as a wave instead of a particle. Who knew?



'Metaphysically engendered' nanocale 3D-printed metamaterial.

One of my favorite Youtube 'influencers' on organic CPUs:



Currently tens of Kilohertz clock speed at 800nm. Suitable for low-bandwidth applications. Like displaying your temperature on your forehead?
