OK, i am NOT pushing any conspiracy point

... at Ken Gee mate... not you...
and also thanks for your post.... most informative..
I guess a few questions come from this:
* Surface ice sublimation has pretty much been ruled out by these investigations... Now we are hypothesising the jets come from something within the comet?
* Why would dust held together by ices form 100m spikes and km cliffs... and not be the smooth dark rounded icey surface predicted by the model.
* Also what strikes me as a difference here in the alternative model is the
action causing the release of material.
Standard Model = Material comes from photoionised... ie "photo" light.. from sun --> sublimating ice either on surface of comet or now some action deep inside?
Electric = Tail comes from Electrostatic discharging of material.... not ice sublimation by a photo-ionising process... eg you can have jets eminating from behind the comet... not required to have a sun-facing effect
* Another difference seems the origin of the material.... Whipple model is dust/ice clumping together in the extremeties of the solar system... oort cloud etc..... what if these comets turn out to be... well... just moving asteroids.... ie hard/rock
explaining the Types of tails is interesting... thanks for pointing this out..
It would seem fair to say we have no definitive model as current...
