Fulle et al. (2016) examined the dust particle material composition encountered in space. Estimating the microporosity of the dust particles and a filling factor, the material density of compacted dust particles is found to be kg/m3. This was updatet to kg/m3 (Fulle et al., 2017) which is a shift towards a higher compacted average dust material density but it covers essentially the same density range as in Fulle et al. (2016) and it fully includes the densities assumed by Pätzold et al. (2016), Kofman et al. (2015) and Herique et al. (2016).

2000 - 3500 kg/m3.
I’ll go back quite a few posts now and dig out my estimations shall we?

What estimations? The density of 67P is ~530 kg/m3. End of story.

Irrelevant, funny flocker you is.
Please tell us how it is relevant. It isn't. Not to the failed EC woo.

So you agree on the dust density estimate?

My wishy washy friend?

Listen sunshine, I'm not the one with a failed model and nothing to replace it. I'm not the one refusing to answer questions on that failure. Your questions are irrelevant. Thousands of tonnes of ice excavated at Tempel 1. Crater too large to have been made in rock. Squillions of pieces of ice around Hartley 2. Vapour detected at all comets. No mechanism to explain that vapour. Et cetera. This thread is about the stupid, failed electric comet woo. You don't want to talk about that, so what are you doing here?

Settle Gretel, your living in the past with an outdated model.

Rosetta has knocked Whipple’s old model for six and out.

Every new paper tends to confirm the ELECTRIC COMET!

You struggle with the simple fact that there is an ambipolar electric field at comet 67P, the dust has the density of stony meteorites/asteroidsand is highly negatively charged and sublimation is untenable as a mechanism to emit the observed dusty jets.

Poor fella.

You are talking utter crap. There is no electric comet model. It has been debunked. There is ice. Therefore you fail. There is no rock. Therefore you fail. There is vapour. Therefore you fail. There are no discharges, or EDM (lol). Therefore you fail. No mechanisms, no science, no evidence, no model. Therefore you fail. Still batting zero.
And ambipolar fields are irrelevant. You fail.

Who said the dust is highly charged? And all those things happen at asteroids. Why are asteroids not outgassing? Answer.
