The kind of yeast in question can't produce alcohol as far as I can tell, only lactic acid. Edit: Lactobacillus not yeast

I told myself I wouldn't do it but I did the research: turns out there's one company who claims to brew with "donor" yeast and that's the company she's talking about partnering with. As far as I can tell from everything I've found reporting on them these claims are unverified so everything below should be taken with a large amount of skepticism.
Their websites are pretty sparse with information (and unsurprisingly creepily neckbeardy) but looking at what's available and been reported I've been able to piece together what I think is happening. They talk around it and try to couch it in scientific jargon, it sounds like they're using it to produce lactic acid only, so no alcohol, which is then sterilised and filtered to death before being used as an additive.
All in all it seems that the steps they describe between "donor" and beer that would result in no actual yeasts from the "donor" in the beer at any point, or even any yeasts cultivated from the originals - Which would seem to be the ultimate intent, probably for food safety law complaince. And this all assumes that they aren't just lieing about it.
They can, to an extent, if you had lots time and a staffed lab. Crossbreeding yeast strains is kind of tough as most of the ones used in industrial fermentation (ie the stable, commonly used ones) don't breed well with others and when they do crossbreed, the resulting new strain is often infertile itself. It's possible, but difficult, unreliable and the resources required put it well beyond the scope of people who don't own a brewing company.
Without any additional research beyond my homebrewing experience, it's possible but very unlikely - almost everything would be against you. Brewing is a pretty fragile process and whilst homebrewing with wild yeast is possible, its a struggle to keep it alive long enough for it to reproduce to sufficient quantities to do it's thing. And that's if it can even get the alcohol content high enough and you don't get any bacterial or mold contamination.
The ruse was a success - they've finally revealed their location, send in the retrieval team. Their fines will pay for a new library.
I can't help with most of this, but having worked in computers for a while, depending on the length of the power outages have you considered a ups battery backup? They're market towards computers and are reasonably priced.
I think it would likely be used to add extra charges after the fact ie did you get caught? Then you must have also commited this crime on top of the others. Then again I might be ascribing logic where there is none.
This guy's trying to trick us into working out - Get them!
The thing I always remembered about mum was her huge, oddly human smile.
Also not all yeast strains convert sugar into alcohol, the strain in question in this case will only produce lactic acid.
