Rocky linux is definitely for desktop too. It was designed as a successor of Centos, which was widely used in medium and big companies. We currently use Rocky 8 where I work. It works fine.
100 is a bit much, a good ebike can cost several thousands. IMHO the main driver for adoption is the availability of dedicated infrastructure. I can afford an EV but chose to use a bike because the infrastructure is excellent where I live and it allows me to avoid traffic and congestion.
For trains and subways, you can build the stations slightly above the rest of the tracks so that a train will naturally break when reaching the station, and accelerate when leaving. Efficiently storing energy in potential gravitational form. I'm not sure how frequently this is done, but at least in my city the subway does this at most stations.
Except they launched them 4 at a time on Ariane 5 (which has similar capacity as falcon, so doubtful they would launch much more at a time with space, also it was available at the time of the start of the project...), and two at a time on the cheaper Soyouz. Also, it's way better to pay even 200 million (more likely less than 150 millions) to domestic companies to boost your own economy than to pay 70 million to your number one competitor...
The launch costs of Galileo satellites were much cheaper than 400 millions per satellite. The budget you mention covers the global development, deployment and continuous operation of the project.
Except when it's very cold outside, which is what was discussed here. Heat pumps are great (have one in my home), but it might not be ideal in very cold areas, especially if electricity prices are high compared to other energy sources.
I have two kids and use a bike (for ecological reasons). I realize I'm incredibly lucky my area has very good and safe biking infrastructure. Had to upgrade to a electric cargo bike when the second one came about, but I don't regret at all, it's more'confortable and safer for the kids. I do own an old ICE car, which I considered replacing with a new EV, but since I drive maybe a few hundreds of kilometers per year, I figured it'd make more sense to keep the old diesel than to replace it.
Turns out there is another trial in France right now, for pretty much the same thing, concerning the centrist party. Left-wing parties have had similar practices too. As much as I hate Marine, this was and is still a very general behaviour of all political parties to misuse available funds for their benefits.
Both exists, and salt can have both. Fluor in the salt is quite specific to Germany and a few other countries though.
