MrHydrohead has a series of videos on their multi-year renovation project for their off grid domestic micro hydro power system. While not taking an existing on grid system off grid they renovate their failing off grid hydro system from 1996.
There are 3 short project summary videos the have notes that show which project video covers the topic they are discussing so you can find more information. One Two and Three
For cases where injury was sustained there is legal doctrine know as the Eggshell skull rule
The rule states that, in a tort case, the unexpected frailty of the injured person is not a valid defense to the seriousness of any injury caused to them.
To add context this isn’t a hypothetical situation. In New York Two cops Eddie Martins and Richard Hall raped an 18 year old woman they had arrested for marijuana possession. They detained a group of teens, and let all of them go except for the woman who they then handcuffed and raped in the back of their police van. They then dropped her off in another location. She went to a hospital where a rape kit found semen matching the DNA of detectives Eddie Martins and Richard Hall. Both officers claimed that they did have sex with her, but it was consensual. Because it wasn’t specifically illegal for police to have sex with someone they detained they were able to accept a plea deal for taking bribes and official misconduct where they got 5 years probation with no jail time. Because of this case New York unanimously passed a new law (SB S7708) making it so that a person “under arrest, detention or otherwise in actual custody” cannot consent to sex. In any other state that doesn’t have a similar law it is essentially legal (as in it is not specifically illegal) for police to rape someone they arrested.
While I generally agree with this it feels wrong in this case since everyone who bought it can get a refund.
