And who also said "you'll be ok" to the Hurricane Helene survivors. Fucks sake

I guess it comes down to whether we want to primarily communicate battery size in terms of charge (Coulombs = Amps * Time) or energy (Joules = Watts * Time).

The first metric you multiply by your operating voltage to get the second metric, whereas the second metric you have to divide by your voltage to get the first. Depends on what comes easier to most people.

I was just thinking about this: peer review admin actions. A first admin could initiate the action, then the peer review could be assigned randomly to another admin - randomly so that admins can't create specific cartels to team up on specific topics.

And it'll be one of her worst decisions of this campaign

Yeah I was about to suggest F-Droid as a FOSS alternative to Google Play.

~~Just looked it up though and Organic Maps is not coming up~~

Edit: Just kidding, guess it's coming up now. Make sure to select the right anti-feature settings!

You can use FireFox and set your default search engine to Ecosia's. Best of both world's.

There is also a FF extension called Search For Trees that defaults to Google's search engine instead of Ecosia/Bing where you don't have to pre-load each search with #g, unlike Ecosia. The Google search in this extension is a little wacky though so not perfect. Search For Trees donates to Trees For the Future btw.

I agree: transportation will probably favor hydrogen over batteries.

That being said, to pile on hydrogen, I'm not sure if I like the water demand part of it either. Coastal hydrogen production might make sense if sea water is the feedstock and corrosion/discharge can be released to the source in a manner that doesn't lead to biodiversity death.

Then again, fossil fuel and mineral based (thermal) energy sources like coal, nat gas, oil, and nuclear all require cold water for cooling purposes. If we transition those sources to hydrogen production (and maybe use in the case of 100% hydrogen fired CCGTs that GE, Siemens, andbMitsubishi are making), there might actually be increased water demand since you have hydrogen + cooling.

It'll have it's niche, that's for sure. But I wouldn't count it out.

And on the topic of better solutions, I'd love to see vertical underground pumped hydro storage pick up steam (buh dum tss). I don't see how underground pumped hydro isn't feasible since we already do geothermal in the same way.

Don't store it in diatomic form. Ammonia is the common alternative for hydrogen storage and transport, iirc

And even if round trip efficiency is poor, if renewables are in excess, it would be so much better to dump that energy into something that to have to curtail.

In a region like Finland, sand batteries appear to be worthwhile for seasonal storage. Might be an avenue to pursue

Then there's always green hydrogen as well

Great point, thanks for bringing it up
