Conversion to absorption cooling ?
Hello. The condenser, capillary tube, evaporator are canibalizable from a discarded system. Removing the electrical driven components; how feasible is to convert to absorption ? When I was 19, attempted to convert a (kerosene) absorption refrigerator into an air conditioner/cooler for my car by using its exhaust gas heat. Got one but resulted too big and when a pipe punctured, the ammonia leak shock forced me to forget it. Scary. From a video I saw recently seems can be humbly done without nasty gases. My heat source is free. The video in miniature is here ---> https://www.youtube.com/watch?v=9DYnaHRpJL4 This is not a 'tinkering' forum nor for HVAC experts but comments are welcome on how would a dwelling could use such conversion contraption. The basic 5000 BTU 'window' airconditioner... how many Watts heat would need ? 1500W ? (As a reference to a larger system) The HVAC systems as pictured are discarded daily; could these be converted/reused; or, a simple 'window' unit ?

Foucault currents...
Hello all. A magnet moving/sliding/spinning next to a conductor generates the eddy currents within the conductor. What if the conductor is an electrolyte ? As in moving/spinning a magnetic field next to a glass vessel with a conductive fluid ? Or reverse, moving an electrolyte within a magnetic field ? How would you set up an experiment to prove the presence or not of electrical current in the fluid during the magnetic field motion ? (Not about propulsion as in MHD, just the electrical eddy current)

Genetically altered silk worms...
As read on a video, the alteration produces spider web strength silk, claimed to make stronger than kevlar fiber. Am sorry but got it not in English. ---> https://www.facebook.com/share/v/1HJPAjJQce/

Spills from paint cans...
Every time that I needed to deal with paint; was the same unavoidable messy spills. Today I fixed the always nasty situation. Cut-off 2 litre soda bottle necks; drilled 25 mm holes on lids and force inserted from inside. Made a couple. The lid can be transplanted to a next paint can when emptied. No need to make many. Simpler in plastic than metal lids. Am happy, this has to be a good thing.😀 There is larger necks in juice bottles if preferred... Edited... Someday I will learn to attach images...

Super El Nino is here, breaking records and altering ecosystems
This is as today : Trouble if the area east of Japan moves east, and the Galapagos goes west.

By merit or lottery, somehow you earned a short interview opportunity to ask / offer / learn something from an alien entity in planet earth. What would you say ? 🤔

Greetings. Is there current or past nations, civilizations or uncivilized races or groups that had zero professing behaviors or activities about gods, deities, totally atheists ?

Which fish not to eat ?
Catching several fish, hook or trap or spear... Is there a test to check if this, that or the other species is 'not edible/poisonous' ? Is it the same story as mushrooms, relying on someone else experience/knowledge ? Is there a 'poison tell tale" test ? If a laboratory test is the way, what does the test looks for ? -Move to another section if deserved-

Results of blood tests...
Greetings. If a person with excellent diet habits, a stable and very good health indicators gets a blood test just after an unusual 'festive-abusive' diet day; like excess of salt, or sugar, or alcohol, or lipids, or whatever; do results reflect the test as if was a 'normal' state or there is something in the results that shows being a recent anomaly spike or is it indistinguishable ? In other words; can an adverse blood test be a result of a very recent 'abuse' and not normal for the patient, to supposedly return to 'normals' in a few days ?

- Extracting water with metal-organic frameworks...
---> https://www.electricaltechnology.org/2026/02/nobel-chemist-turns-air-into-water.html At the heart of the technology are advanced materials known as Metal-Organic Frameworks (MOFs). These specially engineered materials contain billions of microscopic pores that can capture water molecules from the air. Despite weighing only a few grams, MOFs have an enormous internal surface area, allowing them to absorb significant amounts of moisture. Imagine producing clean drinking water straight from the air, even in some of the driest places on Earth. That vision is becoming a reality thanks to a groundbreaking invention developed by a Nobel Prize-winning scientist. As air moves through the machine, the MOFs trap water vapour. When exposed to sunlight or low levels of heat, the materials release the captured moisture, which is then condensed into clean liquid water. Unlike many traditional atmospheric water generators, the system does not rely on energy-hungry cooling equipment. Instead, it operates using solar heat, making it suitable for off-grid locations. The invention is based on a branch of chemistry known as reticular chemistry, a field pioneered by Yaghi himself. The technology can reportedly work even in environments where humidity levels fall below 20 per cent, opening up possibilities for arid regions where water is scarce More at: https://economictimes.indiatimes.com/news/new-updates/no-rivers-no-wells-no-rain-needed-how-a-nobel-prize-winning-scientists-invention-produces-up-to-1000-litres-of-drinking-water-daily-from-thin-air/articleshow/131485522.cms?utm_source=contentofinterest&utm_medium=text&utm_campaign=cppst- Extracting water with metal-organic frameworks...

Fourth release of classified files from ---> https://www.war.gov/UFO/- Another energy storage system
If you are not near a mountain you will have much, much less wind as source in the lowlands for storing energy. If there is no height, would be like putting solar collectors in the shaded slope of a mountain. Things are done at locations where deserve being done, even with transmission lines from generation to consumption. As there is no solar generation in the Sahara, with no consumption there.- Another energy storage system
It would be much more simple to raise the weights to a mountain slope than constructing a tower/building to support them.- Could aliens ever visit Earth?
It is a video. For the question in the thread title. Feel free to delete, ignore or not. ---> https://www.facebook.com/share/v/1APHZe2vcw/- Could aliens ever visit Earth?
Related to your comment, hope attaches. If not, will post its 6 pages. oppenheimer_einstein.pdfoppenheimer_einstein.pdf Seems it refuses to paste. Changed to a link ---> http://www.wolfbane.com/articles/OE.pdf- Could aliens ever visit Earth?
The fuzzy grainy and redacted contents is what qualifies the disclosure as for unidentified to keep you scratching heads in the dark. The absent files that you 'want to know' are the hidden, and not a qualified 'need to know'. When hidden identified files become released, then you may be pleased. If ever happens. 😒 Transparency is about the unidentified and unresolved, not about the hidden for decades. - To sustain life long term in outer space...
