Perhaps there is a rule against it or perhaps it’s just foolish, but if disc wheels make you faster, why not some lite enclosure for the frame triangle between the top, seat and down tubes?
Because it does not work; interference drag; one of the few instances where this has been shown with data backing it up. Do a quick search for Trimble.

Thank you, I will take your word for it.
It was just a bit slow at work today…so I started thinking…

Sucks when you have to do that

There was one issue with the Trimble that nobody ever seems to talk about - shape.
Flat sides are never going to make a bike fast at any yaw > 0.

Doesn’t that just make the frame one big faring? Like a full frame version of the P4 water bottle? I thought farings were generally faster. Actually I thought they were banned, at least by UCI, no?

Well, It technically was not a fairing, as there were not ‘tubes’ under there. Look up Brent Trimble on google, and you can see where his carbon techniques led to. The thing is that the P4 has the bottle in a different place, and ‘filling in’ a different gap. You have to look at the system as a whole to answer this particular question (which is not so, it seems for other parts of the aerodynamic question). This is the only instance that I have heard of on bicycles where a rider on the bicycle resulted in such a different result than a bicycle without a rider.
