Imho hydrogen on trains is only a good idea, for long distance trains running on not electrified track. Hydrogen is more energy dense and easier to refill then a battery so a good idea for say US freight trains.

However Germany has all its mainlines electrified. In this case all three towns have electrified main stations. Battery trains are a good solution for that relativly short sections of unelectrified track, as long as charging can be done in stations. This would be the case here, as in most of Europe to be honest.

Also look at high end windows laptops. They are often easier to repair then Apples devices. Batterie, hard disks and so forth can be easy to change for some of them. This can make those last a lot longer.

But honestly most none Apple software able to run on Macs also runs on Linux. If you do not play certain games or use some very specific windows only software, Linux is a great choice. Just give it a try, it is free after all and it is rather easy to get an old laptop or computer for free.

I have no sympathy for anybody waiting for a device to do X, when Mastodon is the clear and better alternative.

Yes, yes and yes

There also is using old buildings in a new way. I really like Bofills La Fàbrica for that, which is an old cement plant turned into a private home and work space for his architecture firm using.

Obviously earthships are great as well, but they unfortunately are often not that community driven. However they are nearly independent from the modern world made from garbage:

There is also a lot of value in looking at traditional architecture. Hassan Fathy is a good case in that. He desinged very simple practical buildings made from cheap local natural materials trying to serve poor Egyptians the best he could.

The project was always dumb. The way you do it, is to have one large project in the new city center to grab headlines and create a symbol for the city. The rest should be cheaper lower end buildings. NEOM is just the expensive mega projects, without the normal construction.The simple truth is that Saudi Arabia has just such a project with the King Abdullah Economic City, with what is planned to be the tallest building in the world. The issue is that Saudi Arabia just can not be a playground for the super rich. There are just not enough of them to make it work.

Suburbs are like most cities built on good farm land. It is also usually around a dense city core. So it would make a lot of sense to me to turn suburbs into an agricultural zone, rather then complete wilderness. That is some suburbs should also be densified. Something like a McMansion could be turned into multi family housing, the garage into a flat and so forth. Roads are around and parts of them can be turned into protected bike lanes and some proper public rail based transport is an option as well.

I am thinking this:

We literally destroyed perfectly working pedestrian neighbourhoods to make them better for cars. I can not see how having bicycles earlier would have changed anything. We had trains well before cars and at a massive scale and they did not stop cars either.

Shutting down solar is super easy. You just need a switch. Wind is a bit more complicated, but it is basically stopping the rotor. The reason for negative prices are subsidies. So they can sell to the government or get some extra money as to be able to operate them properly.

Also we do not need to store insane amounts of electricity. As soon as your grid is large enough weather balances itself out fairly well. For the EU the worst production of solar and wind combined was still 897GWh in a day last year. The average was 1770GWh per day. So worst case it was half the average prodcution. If you go weekly it is 9335GWh and 12423GWh respectivly so even less. So you really only need a good enough grid and something like a days worth of storage. That actually ends up being pretty reasonable, as soon as you consider stored hydro and other flexible electricity generation.

Lemmy has nearly 2million daily users.

On Reddit a lot of communities had wikis to explain some core concepts. I feel this might be good alternative for this kind of stuff for lemmy. Especially if user accounts can be synced.

A few things first of all we have a capitalist system today. That means most workers are in wage jobs, so they can not be forced to work for nothing like slaves. That however turns work time into a commodity. As long as their are too many work hours available, the employers have an advantage, as they can just fire you, not hire you and the like. However work needs to be done and when work hours are scarce, that turns into a workers advantage. So the employers have to compete for workers, which means higher wage so less profit and better working conditions. Hence capitalist want to increase the work week and have a lot of unemployed workers, to run their companies cheaply.

However a few things have changed recently. First of all Western workers have to compete much less with competition from overseas. This is to slower population growth and globalization slowing down and even reversing in parts. Combine that with the baby boomers retiring and you have a local worker shortage. That however means capitalists have to treat the workers better and interestingly for a lot of Western workers, that means less work. Obviously they do not like it, but markets work, so they have to offer it. That is why we see stuff like the four day workweek pop up recently. Most Western workers have enough goods and more free time, is preferable.

And what are the logical reasons to do so? Maybe an that the changes you want would leads to a better future? One could call that hope.

In that case, why are Chinas emissions hoing up, when its population is shrinking?

Population growth matters, but the real issue is consumption. Intresstingly people have fewer children in urbaized socitied, when they have all basic material needs meet and womens rights are improved. So we just have to meet everybodies needs to a reasonable level and have to reduce emissions. Population is solving itsrlf at that point. If we did that global population would peak before 2050 and fall to about 6billion by the end of the century.

That is it. Most people want climate change to end, but without any change for themself. That however just does not work.

The good news is that as soon as the systems of phasing out fossil fuel are in place, that momentum helps to keep it running.

Lenin did not like the Greens.

It is called density. Bologna is five km wide and something like 13km long, although there is a motorway running along a site of the city. So you can be in any part of the city within less then half an hour by car. Bologna has a huge old town, which is not designed for cars at all and you are probably faster with a scooter.

Welcome to decent city planning.

Thats because it is.multi religious spirtual building with a public park around it. It does not show the buildings used in day to day life. The planning is not that great to be honest, but the place is working fairly well and has some really cool stuff going on. When you make it over 50years you do have a properly working community. The real plan is this:
