Comets are electromagnetic plasma phenomenon. They have nothing to do with ice or frozen gases (but ionised gases are *very* important); that is why 100% of sattelite-investigated comets have had surfaces of rock (regolith), not ice. Constraining your thought to Whipple's horrendously outdated comet model will only continue to result in endless head-scratching and puzzlement. Plasma physics on the other hand holds 100% of the answers to cometary behaviour.
