Default Could we use endothermic(heat absorbing) reactions to reducehurricane strength?

Hurricanes grow stronger over warm waters and correspondingly lose

According to the graphic on this page, the temperature only had to be
reduced to about 75º F for this to occur.

So could we cover the expected hurricane path with chemicals that
produce a temperature reduction on mixing with water to reduce the
ocean temperature?


[snip crap]

Cylinder of water 70 miles in radius and 25 feet deep. Cool from 90 F
to 70 F,

(pi)(112.65 km x 10^5)^2(7.62 meters x10^2)(11.11 C) -- 3.38x10^18
calories
3.38x10^18 calories = 1.41x10^19 joules = 3,378 megatonnes equivalent

Ya gonna absorb that energy with dissolving ammonium nitrate, git?
Cylinder of vegetable oil 70 miles in radius and 1 cm thick,

(pi)(112.65 km x 10^5)^2(1) = 4x10^14 cm^3 = 10^11 gallons

Gonna pour oil on troubled waters, git?


Maybe we could use some kind of reversed nuke to suck out the heat and blast it
into space...
