  1. Fear + ignorance = religion = that thing zillions of people pray about daily for the last 5000 years with zero point zero results nor a single response ever and will continue like that.

  2. Thank you.  The same way the impregnated felt discs that work very well by 'proximity' without covering the metals  ?

    Applying a grease/vaseline covers/shields the metal from fumes? to avoid the corrosion;  fluids applied do something different more in the neutralizing the fumes action, and the felt rings work in some other way I do not know.   A pertinent patent mentions lithium grease + sodium bicarbonate + magnesium oxide 🤨 as the chemicals that impregnate the felt pads.

    Would felt impregnated in weak household ammonia perform ?

  3. Repeatedly see illustrations on how extensive the ice age was thousands of years ago, covering to about 45-50 lat.N and beyond.    But never see the same depicted for southern latitudes.  How was the equatorial climate and temperature then ?  

    And the equatorial flora + fauna did adapt and evolved in such 'short' amount of time to now tropical temperatures ?  Or was the temperature gradient such brutal from the icy edges to equator ?

  4. Greetings.

    A hose/pipe/tube is friction push-inserted into a vessel tight hole.   Transport yourself to the interior of the pressurized vessel.  You can see the inserted pipe end that supplies the pressurized -say air-.

    3" x 21 ft Schedule 40 Black Steel Plain End Pipe | Fastenal

    There is in-diameter and out-diameter, corresponding to inside area; outside area, and the smaller torus area from the pipe wall.

    What is the force the air pressure in the vessel pushes the pipe out towards unplugging it ? ---> force = pressure / area

    Which is the area to consider ?  inside, outside, torus ?

  5. Thanks, fellows.

    1.- From what I read, sugar mash does not produce methanol.  There is a contrary opinion above. THAT is why I created the thread, to find science facts, not hillbilly tales.

    2.- As the topic may infringe in legality; please close the thread if deserved.  I do not want to be the cause of trouble.

     

    Edited, added : Post #2 clearly says to avoid 120F.   FOR WHAT ? making the mash or distilling ?      THAT is what pisses me off from youtubers and brought me to a science site with sharp people.
