There are also gravity batteries: https://www.euronews.com/green/2024/02/06/this-disused-mine-in-finland-is-being-turned-into-a-gravity-battery-to-store-renewable-ene

The gravity energy system would be able to store 2MW of power and integrate into the local energy grid. ... Scientists from the International Institute for Applied Systems Analysis (IIASA) found that the world’s abandoned mine shafts could store up to 70TWh of power - roughly the equivalent of global daily electricity consumption.

Also in Finland, but different technology "sand batteries" https://www.bbc.com/news/science-environment-61996520

Finnish researchers have installed the world's first fully working "sand battery" which can store green power for months at a time.

The developers say this could solve the problem of year-round supply, a major issue for green energy.

Using low-grade sand, the device is charged up with heat made from cheap electricity from solar or wind. The sand stores the heat at around 500C, which can then warm homes in winter when energy is more expensive.

While I think there is still no working production model, Iron Salt Batteries are very promising https://en.wikipedia.org/wiki/Iron_redox_flow_battery

There are different options, not each one is suitable for every place, but seams possible that combination can help us achieve needed reduction in fossil fuel usage when sun is down and no wind.

While being right about crypto being meaningless for some people (I guess there are people valuing hope in decentralized monetary system, even if it is misplaced.), you failed to mention that most of other industries are equally meaningless and good part of them are even harmful: fashion, fast food, industrial food, banking - in a way we have it, cars in current form(no need for this huge tanks)...

In comparation crypto is just wasteful and isn't harming anyone.

Even people in those local governments might see some of the videos and start thinking.

A lot of people are not corrupted evil politicians, they often just don't know any better.

I have learned a lot from those video, examples, good and bad, from around the world that I share with people around me. I hope they will share and at some point someone that has power will hear it too.

They are still a minority, most of us just wants silent clean car that's cheap and safe to drive.

We also want batteries in our homes, we will buy as much batteries as they make, demand was never the issue. But supply is limited and that's the only reason we don't drive electric cars. Batteries and changing stations, people living in apartments have big disadvantage.

I am using linux for 20+ years and don't understand what they said. And I don't even want to, I was using wine to run open source software before flatpak, when I need it once a year.

I came to say that. Not everyone has to change completely, reducing meat intake a little, eating meat with less emissions and even different beef farms haslve large range of emissions. There are different ways of raising beef.

So for sustainability there are multiple solutions.

For promoting veganism and reduce animal suffering only one, which I do support, but don't put them together. It will only pusg people away from any improvement.

Maybe we should stop calling them adblockers.

I am not blocking ads I am blocking spyware and malicious scripts. I wouldn't have anything against well behaving ads without js.

Also making it illegal is nit necessary, just don't show me your content and exclude it from search results and we are good.

Why wouldn't they? It just measures electrical resistance of the soil, less moisture means more resistance. Nice and simple.

I have cheap one connected to arduino, and small water pump conected to it too. It works nicely.

Which brend and model didyou get?

And it is always a question how they calculated handling of nuclear waste.

There are options, we can use coal and natural gas for on demand power to fill the gaps in renewables, we don't have to quit all at once. New ideas for energy storage and comming around, some of them might be useful for small towns, others for remote places.

My GeoTIFFs do not agree.
