Nice thing about mining under the sea is we can destroy another eco-system where nobody has to look at the mess.

Maybe, they could be long dead smokers where the life moved on to another energy source long ago as the sea floor spread apart, we will see. The Norwegians are generally pretty good at managing their environment. I'm not an expert, but collecting nodules from the seabed does not appear to be very environmentally destructive, if done properly. This appears to be another kind of deposit from what I can gather. All mining is destructive on some level and I don't think those rare earths will see as much demand as many forecast, in any case, we have little choice but to move into another technological future, one not dependent on burning things for energy.Nice thing about mining under the sea is we can destroy another eco-system where nobody has to look at the mess.

Just missed grabbing one as it went by yesterday. Closest by-pass ever recorded and was hoping it would take out a Russian spy satellite as it went by.
10x closer than geosynchronous satellites so could have done. Only 2200 miles from the surface of the earth.

I had paid my deposit for Starlink and about a year later, (few months ago), got notice that mine was ready for delivery. I'd been reading about how all those new satellites were f'ing up the night skies for astronomers and decided that I wasn't going to support that so declined and amazingly got my deposit back in a few days.
There are a couple other companies planning to do the same thing so thank Jah for the new James Webb Space telescope that isn't bothered by all that.
Still don't have a decent option for high speed internet here so will fumble along with the wireless we do have.

Story about an active bunch of unique smokers under threat from nearby sea floor mining. Great site for all sorts of science related stories.

Study: Light Pollution Continues to Dim Stars

One of the few nice things about living way up here is the mostly dark skies. Unfortunately I have a gas plant less than a km east of us that has a half dozen big hps lights on their site but stay on the west side of the house and you don't notice it when star gazing. The biggest problems with star gazing is it's too f'n cold half the year and during the warmer months the mosquitoes eat you alive.Study: Light Pollution Continues to Dim Stars
learningenglish.voanews.com
At our cabin in BC we used to lie on the dock early in the evening and count satellites. Crystal clear skies and about 4000' above sea level with no other light than maybe a campfire a mile away on the other side of the lake. The old folks would be inside playing cards and drinking rum and cokes so we'd close all the curtains to block that light and if it was moonless you could till find your way to the biffy by starlight.
A want of mine is a remotely controlled telescope so I can sit here in the mancave and travel the universe on a screen inside. My 24" monitor just packed it in so time to whip out the VISA card and score me something worthy of such a scope.
If it clears up I want to get my cheapo telescope out there and spot that green comet going through. Can't take pics with it tho.

The moon is now a factor. Gotta look in the wee hours after moonset. In my big binos it is easily as big as the moon. Comet is close to Polaris next coupla days.One of the few nice things about living way up here is the mostly dark skies.

Lithium-ion outperformed. Again!
29,242 views Jan 29, 2023
Lithium-ion remains the battery energy storage technology that all newcomers need to beat if they want to get a share of the market. More of more of them are looking like doing just that, including an alternative chemistry using one of the Earth's most abundant substances. So can this one disrupt lithium-ion's dominance?

I had no idea Canada was so involved with LFP development and production and will be again! These long lasting cheap batteries can power small economical shorter range EVs and scooters and are a favorite for home solar energy storage. Sodium ion batteries could out compete them for cheap EVs though. There is a lot of work being done on batteries world wide using a variety of chemistries and approaches, a lot of cash is being invested in battery and supporting manufacturing plants. We should start to see the results on the road in North America in a few years as automakers bet the farm and governments jump in to kick start things.
The transition of the automotive era looks a bit like it's beginning, back then lot's of technologies were competing from steam, to electric with ICE winning eventually. It will probably end up like that for EV batteries, with range, durability, reliability and of course price determining the winners in the Darwinian marketplace.

Companies are planning the first large-scale factories in North America for the inexpensive raw material

You may not be seeing this in your EV anytime soon, but it is bound to make many in the industry standup on their hind legs and take notice! If it works, it would make electric aviation practical, at least the light and short haul airliners.
Practical lithium-air battery shows 3x the energy density of today's best electric-vehicle batteries
Electric vehicles are great, but there’s a lot of room for improvement in the batteries they use. Same goes for energy storage associated with renewables like solar and wind. Electric cars currently use lithum-ion batteries, because they have the best energy density (energy storage per weight) of any practical battery type we’ve got.
But there’s another type of battery on tap that threatens to upend this and change the whole landscape. It’s the lithium-air battery, which has been around in labs for a while, but it’s been beset with technical challenges. It’s worth the aggravation, though, because as you can see below, its attainable energy density would rival that of even a liquid fuel like gasoline:

The article says it is, and it is based on an article in Science last week. Other than a minor error in formulation that was corrected in the comments, I didn't see anything wrong with it. They appear to have made a practical breakthrough in the separator and it is quite a departure from conventional approaches. They stressed the practical nature of the advances and in the current environment money won't be long in following, if qualified people think it's worth the bet. This one is a ways off, if at all, but it exemplifies the massive amount of work being done in the field now. The stakes are enormous, private and government money is flowing into R&D, that is why there is a lot of news. The reporting has also narrowed to the more pragmatic solutions, those likely to be in production, preproduction and breakthroughs that will make to production or enhance products already in production over the shorter term. Now that big money is involved performance is measured quarterly so there will be expectations!

Too new news to have an English article apparently…
Germany’s government: natural gas powerplants will be unnecessary in 10 years.
The goal to stop using coal has been moved forward, from 2038 to 2030. For generation electricity, gas is no longer considered an option to transition or meet intermediate self-imposed emission reduction milestones. Aside from solar, wind and geothermal, the successor of natural gas (in Germany but also NL and others) is green hydrogen. The idea in Germany was to repurpose gas powerplants into hydrogen powerplants but a new report shows that‘s not feasible. Except for one plant, all subsidies to convert plants will go to hydrogen plants (their last few nuclear pants will shut down soon).
Aside from producing it locally, NL will become a major hydrogen hub this part of Europe. Both NL and Germany want to import massive amounts from Australia. To use as basically a battery, but also to burn mixed in to natural gas while that is used. In the UK there’s a trial going, starting at 3% hydrogen, planned to go up to 20%.

After reading the Wiki article on Li-air, it sounds like we will have steady-state fusion energy before arriving at a practical battery on this chemistry.
