You put small clips on the bottom of the cable trays. In a corner of the room you have a pot with a plant such as a philodendron. It grows up to the cable trays and along.
I've seen this done just using bent paper clips hanging from the frames holding ceiling tiles. It made for a great office with all that green overhead. Light-weight office plants won't bother the cables if they curl a bit into the trays. If someone is working in the tray, she can just cut off anything in the way.
The office I saw used philodendron, but there may be better plants; it depends on the green thumbs available.
This treats human beings as if they were replaceable robots. In many ways I look forward to a future where actual robots do much of the work. I would trust them much more than most doctors I have met.
There are times, however, when human compassion makes all the difference. These nurses that were fired, will their replacements be as good? If they are not, do you consider the fact that the replacements have the flu vaccine a fair trade?
It costs money to make power and large expensive facilities. You can supplement with wind and solar. Those certainly are worth it for the individual, but not for the group. Power generation must always consider the worst case. If the Fimbulwinter strikes for a month, covering everything with snow and wind turbines with ice, society will require power supplied by industrial grade facilities.
People should install solar panels, yet someone must pay to maintain the huge infrastructure and facilities for when all else fails. A possible solution is that when a person with solar panels requires power from the grid, the rates shoot way up to help pay for having that power available instantaneously when they have a problem with their own. This would discourage some people from installing solar panels, it would encourage others to become completely self-sufficient. In the long run this will prove the best solution; in the short run the power infra-structure must be maintained and paid for whether or not people use solar panels.
Solar panels should not be allowed to put power to the grid. It will cost everybody more in the long run, but people will insist on this and so those costs will just get added to the bills. The costs won't be a sudden hit, just slow and incremental. By the time people realize the cost, a loud vocal minority with a vested interest in selling power from their solar cells to the grid will be able to beat off attacks. That may already be the case.
