I saw you mentioned Maine coastline. Maine has a lot of mineral deposits up and down the coast, and I know of at least one zinc/lead mine.
The metal content is probably because the water is acidic and leaching the natural metals. If that’s the case, redrilling a well won’t give you any benefit. You’d definitely want a filter system anywhere on the coast, and reverse osmosis would make the water taste a hell of a lot better too. (Unless you like that brackish tasting water)
Jesus o.o nearly 0.1mg/liter?
Maybe I’m really bad at unit conversions, someone correct my math:
human is 5L of blood (or 50dL)
98ug/L => 9.8ug/dL
15% of that gets absorbed if ingested
9.8 * 0.15 = 1.47ug/dL absorbed (per dL injested)
Your blood levels exceed worker exposure limits at 60ug/dL, and poisoning ranges from 30ug/dL to 330ug/dL.
So for this, if you drink a little more than 4L of water (which isn’t that hard to do) you’ve exceeded your exposure limits.
Idk how long you’ve been drinking that water, but I would maybe get checked out by a doctor?
Wait hold on
I wonder if I can get the Google assistant British lady to call me that
Edit: Lmfao it works
Here’s the one that felt like a stroke:
You aren’t kidding in the slightest. I started down the path of DOJA cat in racist chats and Jesus fuck that went off the rails real fast.
what the aneurism did I just read
If it bricks my i7 room a I’ll just take it apart and make it work somehow. It will take a long time but worst case scenario it goes from a brick to a brick
Nope! It has a range of speeds. The PWM signal it provides also produces something called “counter-electromotive force”. I don’t remember the exact specifics, but if this measurement falls (corresponding with a drop in blooded pressure) it will increase the pump speed (up to the maximum RPM permitted).
That is how our circulatory system works as well - a drop in blood pressure usually results in an increase to heart rate. I say usually, because I coincidentally have a nervous disorder where this is broken - an increase in heart rate will drop my blood pressure. A drop in blood pressure will also increase my heart rate, which then drops my blood pressure, which causes a runaway and I faint.
You are completely correct. It’s been a while since I was flying.
I’m not actually sure what that battery pack is for. Maybe RC car?
I actually know this! I used to work on an LVAD controller about 10 years ago. The technology is largely similar.
The pumps are centrifugal, they have to maintain blood pressure, and are largely waterproof.
The pumps spin with a brushless DC motor controlled by PWM. Depending on the specifics of the motor the RPM can be between 8,000 and 22,000. Because of the limitations of battery technology, you’re stuck with using a LiPo battery. LiPos are annoying as all shit to deal with. You have to charge them carefully, discharge them carefully, and they’re pretty big.
To give you an idea - FPV racing drone batteries can last several minutes: https://www.getfpv.com/batteries/mini-quad-batteries/cnhl-ultra-black-series-1050mah-150c-6s-lipo-battery-xt60.html On a really carefully tuned racer, you can get maybe 5 minutes out of a quad that would use that battery.
Edit: I was incorrect, the first battery I provided was not the battery that would be used in racing. LiPos are what I wanted to share. The battery now highlights what I wanted to.
Oh. Personally for me it’s code reviews that prevent me from doing it, but pound you in the ass penitentiary is a good motivation too
At what point do we become Borg
