Sydney Water is trialling it in 30 homes across Sydney.https://utilitymagazine.com.au/sydney-water-pilots-award-winning-water-recycling-system
“Granulated” popcorn with good thermal insulation, water-repellent and fire-retardant properties might soon provide a more sustainable building material option than the existing plastic or mineral products which dominate the global market. https://www.uni-goettingen.de/en/3240.html?id=6481
Retrofitting existing diesel trucks for electrification is a costly exercise.

Under development since 2017, this liquid metal battery (LMB) is about to be let loose on the globe. Consisting of 3 liquid layers; 2 of molten metals and a middle layer of molten salts. The system is self-heating and insulated, but contains no combustible materials - so they can't burn. And they retain all of their charge capacity for at least 5000 cycles (think decades, not years). Modular, safer and cheaper than lithium-ion batteries. https://ambri.com/technology/
