Wickramasinghe contends that radioactive elements inside comets are energetic enough to rovide a fluid interior in some, or many comets. I doubt he is right, but without more evidence I don't know if this possibility can be ruled out. However I am not aware that any of the results from cometary probes so far obtained have given any support to this contention.
On the other hand clay-like minerals
are an interesting find in these objects.
