incredible boomer energy in this convo with my mum (who has just been to Singapore):
"they're reclaiming land everywhere, that must be changing the sea levels. How are they allowed to do this? We can't even breath in the wrong direction but they can just do whatever they want"
Does she think reclaiming land changes global sea levels?
can't recall if I posted this already, but here's the github repo for my DIY air purifier. If anyone has ideas about how we can get this out to people who might want one but don't have access to the tools or knowledge I'd love to hear from you.
alright so I'm getting about 2m/s airspeed through the housing. My dodgy calcs (I'm not an HVAC person) tell me that's about 160 CFM, which seems ok because the fan is rated to 186 CFM. That would mean my 25m3 office is getting 10 air exchanges an hour - about right for what we need. I'm sure this is too good for this shonky device.
Right, I think I've worked out a way to measure the airflow through my DIY air purifier. Going to use a drone airspeed sensor inserted into the filter housing to measure airspeed inside the unit, then do some maths.
Just need to find an airspeed sensor and pitot tube in my very messy workshop.... (I have at least one of each somewhere)
a gronk at dad drinks last night tried to tell me that India was shooting nuclear waste into space in the 90s. Because I said "no, that's bullshit" he emailed me a PDF of a 1978 NASA study about the concept (at 1159pm). Dude, I fucking worked on the committee that wrote the COMDISPLAN for radioactive space reentry debris, but go off I guess?
