Yes, adding that slight explanation will help, but I don't think ECT or its elongated form is a suitable substitute because people still refer to them as "bongs" however inacurate this may be.

Also as Cathar mentioned he's seen smaller more compact Evaporative Cooling Solutions that may not represent a tower (Volenti's certainly does not). I am suggesting this solution would not fit in the category of a 'bong' where the typical PVC Pipe tower with shower head resides. I would categorize 'bongs' as an Evaporative Cooling Solution, along with other forms (non-tower/ECT).

This is a bit of a ridiculous arguement about semantics; however, I feel that not using the word 'bong' would only give rise to the question "What is a bong?" Many people have heard of bongs in WCing, less know what one is. I agree that ECT is a good alternative term for bong, however I don't believe alternative ECSs are necessarily ECTs (which sounds synonymous with bong to me).

With proper explanation the term 'bong' is not inappropriate, although without explanation some may think that a bong in WCing is not only a cooling device but serves the dual purpose of ... smoking.

Neglecting to use the word would just be confusing - using it without explanation is also confusing, as you can see I think the only solution is to add another term such as ECT or ECS, but NOT replace it.

[EDIT:Below]

Addressing your audience is important - but I'm sure some percentage has heard of a WCing bong before (and might wonder what exactly one is), regardless of how inexperienced they are.

Also towards parents, if they fear their child building a WCing bong, then they have also been misinformed - either by the child or by euphemistic substitutions such as ECS or ECT.

I'm not saying bong is the name I would have chosen - just that it's here now, don't confuse people.
