bicycling is the only machine of which I know on which lubrication
theory seems to break down. I see no other chain driven machines
that use wax, or for that matter machines that use wax as a
lubricant.
Quoted message said:Yeah, but most machines put a cover on their chains (if not an
entire factory hall). Bikes, being man-driven, are much more weight
sensitive. Plus the derailer kind of prohibits it.
I think you are overlooking many chain driven vehicles and outdoor
machinery that has exposed chains.
Sorry, Jobst, but a bike is pretty close to unique. First, the chain
doesn't run in the normal high speed, low tension conditions of
ordinary roller chains; instead, it's used in tension mode, at very low
pitch line velocity.
Second, it does live in a nastier environment than most roller chains,
by far. Standard industrial practice is to keep dirt, mud and water
away, not to sling that stuff at the chain off a front wheel.
Third, a bike is different from, say, a golf cart in that the operator
frequently comes in contact with the chain, frequently prefers
cleanliness, and frequently doesn't want a chain enclosure.

No wonder he can get along with wax.
Pure paraffin wax is no good in rain. But blend in about 5% oil, and
rain is no problem. My city is one of the rainiest in the country, by
one measure (specifically, the percentage of time that something wet is
falling out of the sky). I use only wax with a bit of oil, and have no
reason to change to something that turns black & messy in 100 miles.
YMMV, of course. But knocking it before trying it isn't very wise.
