I heard a single layer of graphene makes a coating nearly impermeable to hydrogen, but it can absorb it too, it is normally as impermeable as a kilometer of glass!
What is the permeability of graphene?
The precise measurements set an upper bound on graphene's permeability, which is around that of a 1-km-thick piece of glass. However, when they tested hydrogen, the researchers were surprised to see a slow but steady upward membrane deflection of a few nanometers.Mar 30, 2020

What are the limits on gas permeability of graphene?
Despite being only one-atom thick, defect-free graphene is considered to be completely impermeable to all gases and liquids1-10.Mar 11, 2020

I’m not surprised. Graphene is shaped like honeycomb mesh. I’d expect hydrogen to have a fair permeation rate from quantum tunneling through one-thickness graphene.I heard a single layer of graphene makes a coating nearly impermeable to hydrogen, but it can absorb it too, it is normally as impermeable as a kilometer of glass!

Challenges, not problems that form blocking obstacles. We’re already reusing part of the ng pipelines, and 85% of our hydrogen network will be reused ng lines. A portion of it has been updated and extensively tested for 5 years already, concluded to be safe and reliable.
It is, for many. It’s however not a choice between solar/wind and hydrogen, we need both. As I posted earlier, half the rooftops in NL can provide all the electricity need, during the day, but electricity is only a portion of the total energy use. Specifically the industry in Europe needs much more and only a portion of major industries can change to electricity, CO2-free gases will still be needed. Green hydrogen replaces gray-hydrogen and ng and is used as a carrier for green energy from the other side of the planet. Between EU and Australia, it’s a trillions of dollars project of which parts are already operational, i.e. this isn’t an idea for the future.

Oh, I agree, but the infrastructure will need to be adapted for it and there are ways of dealing with it, like batteries it needs more work. Green hydrogen is the key to green steel production and would be used in many industrial processes, but not for cars or trucks I think, maybe ships and airliners eventually. There are ways of storing hydrogen in solids that are very feasible for transport purposes. However, I think most of us are headed for an electric future where we can, but breakthroughs in green hydrogen production are happening all the time too, including using sunlight directly to break apart water. It will be a combo of economics and technology in the end.

Tesla's don't have AM radios, another sign of division on the right? I can't see them selling many EV half tons to farmers in America if they can't have hate radio jacking them up on runs into town! It will be a big issue for the right and rural crowd, they might as well remove foxnews from the airwaves, that would cause much lamentation and gnashing of teeth on the right. However, I think it would make America a different place politically in a few short years. The democrats wouldn't lose a vote over it IMHO, if it was done after they won a hat trick in 2024, shock and awe.

I can’t see them selling many Cyberyucks, period. Thing’s uglier than a monkfish with a birth defect.

The regular ones from Detroit don't have AM radio either, at least the Ford F150 EVs don't.

How to build a kilowatt hour guzzler!
There are still people building cars, but there are fewer of them every year and ya generally don't need to change robots with each new model, just adapt and reprogram them. I can see something like this with a thousand-mile range one day using improved batteries, but it will be a bitch to charge!

There will be lots of layovers in Kennedy Meadows. Also some flip flops for the non purists.The Northbound thru-hikers on the PCT (Pacific Crest Trail) will start to shove off from San Diego in about 2 weeks for their 5-6 month hike from Mexico to Canada thru Cal/Ore/Wa. It's a dangerous trek on a good year(low snow/no fires). But Heavy snow for much of the trail and extreme water crossings will make the 2023 hike lethal at some points. This year will not be for the weak.

Not far away, but not publicized, is a pocket park where a few junipers grew in a protected valley. The flagship is the Bennett Juniper. I’ve seen the Father of the Forest redwood. I’ve seen the big sequoias. I’ve sat under a banyan tree that filled a traffic circle in Colombo. I’ve seen the bald cypress that towers over the Okeefenokee. But this one organism is the pick of the lot imo. I’m sort of glad it gets few visitors.
A scale object.
Near it, “Fred and Ginger”.
