A general rule I used in industry was that on plant air @7-ish bar, it took at least 5 hp worth of compressor capacity do 1 hp worth of work at the end of the hose.... No biggie on a small scale.
My grandmother from rural Saskatchewan said that back then they would exchange their radio batteries when they went to town.
Her husband, my grandfather, lived in Regina but worked on a traveling threshing crew and mentioned seeing a windmill driving an old generator from a car to charge batteries at one stop.
Only 50? I think that's pretty good when considered on its own but STC doesn't look at the whole picture. STC ratings and requirements for discrete wall and floor assemblies are a thing but with suites/party walls apparent STC is what mattered whether it was the provincial code or local bylaws. ASTC is king.
Something I've seen with renovations is construction companies not understanding how to attenuate sound, and not bothering to learn or, even better, consult someone who knows.
Well meaning PMs read up on products and throw them at the problem and it's treated as a great success because there are no hard targets, just a general desire to reduce noise, and that happened.
Where I am in British Columbia, there are sound isolation requirements in the building code so the landlords can't be cheap...but it doesn't help with older or non-permitted work.
I have encountered PDFs that would exhibit this behavior in one browser but not in another.
One fun thing I encountered from local government is releasing files with potato quality resolution and not considering the page size.
I had a FOI request that returned mainly Arch D sized drawings but they were in a 94 DPI PDF rendered as letter sized. It was a fun conversation trying to explain to an annoyed city employee that putting those large drawings in a 94 DPI letter size page effectively made it 30-ish DPI.
I used to show a clip to new helpers/labourers of Fred taking down a chimney one brick at a time because it beautifully showed what a person can do if they just get at it and keep at it.
>A huge amount were clearly faked resumes that far too closely matched the job description to be realistic.
In government work programs in British Columbia, we were taught to address every point or requirement in a job listing that we could. Is this tactic clearly distinguishable from clearly faked?
