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.

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 ?
