"Why double the atmospheric dust concentration in your calculations?"
Remember, i said I'd get back to it.
Quote from: Bored chemist on 15/08/2016 20:21:32

"Aha! I will double the amount of dust in the atmosphere- that will let the world know  I'm not to be messed with!"
  (really, doubling it's not a huge target- we can get back to that later).

Well that volcano very roughly doubled the amount of dust.
And it didn't have a lasting effect.
So, to achieve anything, you need to do better.

And this  "aerosolized jet fuel."! is moving the goal posts- but it still makes no sense. Jet fuel evaporates and is destroyed by oxidation in the atmosphere without making much difference to global warming.
You seem to be making it up as you go along.


What were you saying about wishful thinking?

Ever heard of trimethylaluminium (TMA) ?

From wikipedia:

Quote
Trimethylaluminium is one of the simplest examples of an organoaluminium compound. Despite its name it has the formula Al2(CH3)6 (abbreviated as Al2Me6 or TMA) as it exists as a dimer. This colorless liquid is an industrially important compound but must be handled with care due to its pyrophoricity; it evolves white smoke (aluminium oxides) when the vapor is released into the air.

https://en.wikipedia.org/wiki/Trimethylaluminium

The wishful thinking is to assume this aerosolized jet fuel is nothing more than water vapor.

I have worked with trimethylaluminum. It's really nasty stuff! Pyrophoric is almost an understatement, TMA is violently reactive, bursting into flame and forming fireballs or explosive mixtures with air. I think it is HIGHLY unlikely that TMA is being put on commercial airlines (oh, maybe a TMA confinement failure took out MH-370...) I will point out, however, that some sounding rockets DO release small quantities of trimethylaluminum at very high altitudes to study air currents in the upper atmosphere. However, you have more exposure to aluminum from your deodorant or a potato baked in aluminum foil, so don't get too excited...

more info about trialkylaluminums:
triethylaluminum burning (watch as it reignites by itself after the flame is extinguished)

spontaneous ignition of trimethylaluminum: (start watching at 1:33 if you are impatient)

video of sounding rockets releasing TMA in atmospheric study (release at 2:03)

Nobody said it was.


It would be easier if you stuck to one made-up story rather than leaping from one absurdity to the next each time your beliefs are exposed as nonsense.

Why don't you write a nice clear list of the stuff you believe then we can go through the lot and point out (once and for all) why it is nonsense.

No one with the capital necessary to perform this supposed geo-engineering is going to waste it on an exercise with little prospect of return. They would rather carry on making money in the sure and certain hope that they will be dead before the proverbial excrement fouls up the blades of the fan.
