I’m never one to pass up a good insulated foam nuc, but the beauty of DCoates design is the low cost and quick build time. You can whip these things together in no time and if you’re using them for swarm traps, quantity might trump thermal quality.
What we need is a foam version of the DCoates concept: something QUICK to build, low cost, and relatively durable. That combination of qualities still eludes my adventures in foam. Hmmmm…. Now you have me thinking again :)
