It's a... student project ;) However, the actual amount of energy in those ultracaps isn't that much. We're talking a couple tens of kWs or, in other words, all those caps together don't even hold the same energy as one single li-ion cell (18650 size). The energy density is low, thus, the actual safety issue is fairly minor. That being said, they are in a special Nylon enclosure with polycarbonate sides which provides an effective shield in the case of rupture. But, at the moment that picture was shot we hadn't actually tested that yet :D Again, students.
