Our students get the knowledge they need in the real world.

Buying enough land for a bauxite mine for under $4k sounds tight, unless they're a sponsor.

We've got some trees that were planted by students and they are big enough now that we have been debating using them for bumper wood but we're not sure how to account for the CAWst. Is it just the price of the seed or sapling? Do you think we need to include the cost of the full packet of seed or just the per seed cost, which I think is less than $5? I'm not sure.
Depends, is the sun a mentor and/or sponsor?

Sol is registered as a sponsor.

I'm not sure we account for our rent on the space we're in now... hmm...

Arguable, given the definition of "fabricated":
Quote:
Note that it is possible for an item (typically raw materials) to be neither COTS nor a FABRICATED ITEM. For example, a 20 ft. length of aluminum which has been cut into 5 ft. (~152 cm) pieces by the Team for storage or transport is neither COTS (itís not in the state received from the VENDOR), nor a FABRICATED ITEM (the cuts were not made to advance the part towards its final form on the ROBOT).
I think you could mine, crush, refine, and cast the aluminum into ingots in the offseason, as long as you don't start casting or extruding it into useful shapes before kickoff.
