People are complaining about this, but it makes a lot of sense. Normally, you can't use reverse osmosis to turn salt water in to fresh water without some form of power to overcome osmotic pressure, and that's what makes reverse osmosis desalination a challenge to implement at scale.
Darth Vader is demonstrating that with the addition of The Force, it becomes possible to create the pressure required for reverse osmosis to occur without needing a battery or power supply, and thus, fresh water from the ocean!
I've read once somewhere that a lot of these weird photos used for demotivators came from challenges in GISHWHES.
2011 to 2022 though, and I remember this picture (and similar) popping up while I was in high school a couple+ of years prior, so that doesn't line up.
I love that the weirdness comes from a contest that originated from Castiel trying to get a People's Choice Award for Supernatural 😂
Can a Brita remove dissolved salt?
they're intended to "remove" calcium and magnesium salt ions by exchanging them with sodium ions from the ion exchange resin beads in the filter, thereby softening the water (and to most people making it taste better)
however ion exchange uses osmosis to function. you can "recharge" an ion exchange resin by putting it in a brine with a super high sodium concentration, causing the exchange to run in reverse (the sodium ions will replace the calcium and magnesium in the resin instead of the other way 'round).
so in this photo, the filter is removing salt the opposite way it normally does lol
Very cool to learn!
have personally recharged the ion resin in a Brita filter by soaking it in table salt brine. was a financial godsend when I lived in Arizona, where tap water tastes like eating chalk in the pool
