Norma Jeen @normajeen.bsky.social , thank you so much for including me with these worthy resistors!
And you are right, without these insane US tariffs, China would still be buying our soybeans, etc. And there would be no need to bailout our hard-working farmers! And inflation would be far lower!!

L.A. Kicks Coal As It Fires Up The World’s Largest Green Hydrogen Power Plant
The city starts getting electricity next month from hydrogen made at a Utah plant – and stored beneath it in a vast salt cavern – to help get to 100% carbon-free power.

So sad that #climatechange is forcing changes to growing coffee beans, with the wonderful arabica being hurt by warmer, dryer, conditions that bring more disease.
The result, switching to more robusta beans, a more bitter bean that can tolerate higher temperatures and is more resistant to diseases.

1) NovaSpark Energy lies: no patent, only a patent app on an atmospheric water generator supplying water to an electrolyzer to make hydrogen in the field↙️
2) They claim "portable" MW-class systems. 1MW requires a 5acre / 2hectare PV array, which would take much effort to disassemble-move-reassemble!

#H2Safety101 A thread 1/2
Helium is expensive to fill balloons, so some vendors are using cheaper, home-made hydrogen gas mixes, despite the major safety risks.
BUT, they don't make pure #H2 from water (H2O), but a mixture of #hydrogen & #oxygen. All you need is a tiny spark & boom💥

New research analyses ~2,000 planned and operational (potentially low-carbon) hydrogen projects, quantifying GHG emissions and identifying climate-effective applications.
Global greenhouse gas emissions mitigation potential of existing and planned hydrogen projects - Nature Energy
Hydrogen could be crucial for decarbonizing various sectors, but its production is resource intensive, necessitating strategic prioritization of applications. Here the authors analyse approximately 2,000 planned and operational hydrogen projects, quantifying the associated greenhouse gas emissions and identifying climate-effective applications.
