Main Question or Discussion Point

http://www.abc.net.au/science/news/stories/s1443052.htm
One of many articles on the proof that lightning is caused by ice flying around in the atmosphere. Apparently meteorologists are pretty certain about this. What about on Venus? There's a lot of lightning there, but certainly no ice.

What do all of you think on of the cosmic ray theory of lightning formation?

Didn't have time to read the link, but I've heard the same assertion many times. Still, no matter how I search, I can't seem to find a report of a spark being generated this way in the lab. Has it been done?

Regarding Venus; I suppose that, if ice crystalls can generate lightning, crystals of amonia or sulfur or anything else that crystalizes when it freezes would do the same, would it not?
