OpenWRT does not use liblzma or systemd so i think that one is pretty safe. I would also be surprised if Android included OpenSSH server binaries in that way.

There has been some fusor research going on for decades. The issue that killed that direction of fusion research was ultimately that the electrons do not behave as the initial simple models suggested and in the real world the power loss from the fast electrons is just too big for any reasonably sized device to allow for self sustaining fusion.
If you want to be super exact about it it would be roughly 4 times the mass of limescale + mass of already dissolved CaCO3 in your tap water (you can look that up if you know the hardness index of your water).
But really just don’t be stingy with citric acid and it will be fine is what i am saying.
Here is the math:
2 frac {210.14 g/mol } {100.0869 g/mol} approx 4.2

Note that citric acid works a bit more nuanced than many other descalers: it acts as a chelating agent at high concentrations (2x the Ca2+ concentration) and is more effective at removing scale because of this effect, but at lower concentrations the effect might actually be reversed because it can form solid calcium citrate, which has a very low solubility in water.
If you are using citric acid based descaler you should make sure that you are always using enough of it to avoid the formation of calcium citrate.
Looking at the price per kWh for commercial batteries tells me that we are seeing the battery revolution right now.
Graphene is already commercially used in some applications:
There are already very effective cures for some types of cancer (note that the differences between the many types of cancer can be huge and so the effort and time needed to create cures will also be very different. some treatments also are effective but not completely understood yet, like for bladder cancer)
Nuclear fusion devices are commercially used in material analysis (mostly in the semiconductor industry and in ore processing). There are different types in use – some even use thermonuclear fusion on a small scale.
It all seems like super crazy superconductor level tech until it becomes mundane and part of peoples lives … then we stop noticing how amazing it really is.
woah this is awesome!
maglevs need classical wheel systems anyway because there might be a power outage, so simply having wheels that are compatible with the local rail system is a brilliant idea.
add in a tiny propulsion system so they can use the normal tracks at low speed without the help of the maglev tracks and you can sort of blend the two systems together in critical locations like switches and train stations.

This guy was in a remote controlled, parachute equipped gondola at 17km altitude wearing a pressurized suite. His suit broke and even though the emergency descent of the gondola was immediately activated to descend safely, he later died from embolism (bubbles forming in the blood because of rapidly decreasing pressure). Passenger jets cruise at about 11km so i gather it would be similar.
