My college fitness center recently purchased some new treadmills that can go up to 15 mph.
How long could K. Bekele run at this pace under the following circumstances:
Treadmill is accurately calibrated
Test is run at sea level and at optimal temperature
Zero incline
Large monetary incentive (100K for reaching 8 min + 100K for every minute that he lasts beyond that point)
Bekele is in WR 5000m shape
Could he last beyond 12-13 min?
If he was in WR 5k shape, he would easily last 13 minutes. At 15 MPH wind resistance is not negligable:

5:00 pace only feels like 5:13 due to lack of wind. The difference will be greater at 4:00 pace. How long can KB hold 4:15-4:20 effort? A while I would bet.
maybe 2 minutes max before he was out of breath.
I have read that he can only hold that pace for .4 miles or 1min 36 sec.

I agree, although for most of Bekele's fastest times, he's had a pacer to break some of the wind for at least part of the race. The reason that I thought he might not be able to last longer was that, for me at least, running on a treadmill is extremely monotonous and is tougher mentally than running on the road or the track. I think this might have a partial nullifying effect on the advantage of not having any wind resistance.

Why in the world does he have a pacer farting for him?
Pay him a a thousand dollars/sec and I bet he will not find it monotonous at all.

For me, running on a treadmill is easier. I don't have a problem with the monotony, the heat is the only thing that gets me, so i usually have a couple fans on me.I bet someone like bekele, whose entire career is based on being able to push themselves when they don't want to (I am sure he gets bored of running sub 13 5ks, but does it from the $) would be able to push just fine on a treadmill.

forever if he put his feet off to the side

I don't think winning ever gets old.
I bet it does. It's like local road races. I can run about ~15 minutes on the road for a 5k, the next closest in my city is about 16:30 (small city). I do not get excited about those at all, I get excited about races where there is competition. For Bekele, some races are like these local races.

If he went fast enough, could he take off?
only if he had the feather
very interesting question
takes lot of working out
for most accurate wind resistance estimate, use jrm's calculator :
http://myweb.lmu.edu/jmureika/track/wind/index.html
we have 4'00 pace ( 14.91s for 100m ) on a treadmill without the wind resistance outdoors
we need to add wind speed of -( 1609.344/240 ) to this for outdoor equivalent = 15.33 s for 100m or 4'06.7 pace for mile outdoors ( 6.52m/s constant speed )
to work out how far he can go, we need :
& enter his best 5k/10k at his peak with adjustment for wabbiting
he was probably 12'35/26'10 at his peak with perfect pace
now, wabbiting offers ~ 1s/lap advantage & normally it is to 3k in a 5k ( 7.5s help ) & 1/2 way in a 10k ( 12.5s help )
therefore he was likely in solo shape of
12'42.5/26'22.5 at his peak
enter those into the predictor & by trial'n'error find the distance which offers 6.52m/s ( see above ) ->
5550m in 14'11
ust over 14 minutes at 4'00 pace on the treadmill !
