Andy, As a beer drinker and a frequent tropics visitor I love the idea. Only issue is for travelers to carry home. Wood (cellulose) is a standard insulation material so the expected heat transfer rate should be very slow. Also the limiting effect of the enclosed space with no air flow would also slow the heat transfer. A little carving on the outside with bar emblem or country flag would make it more attractive to me.
Thanks for the good news,
Chris, he is a newbie on a missiop, too busy to know where he has been. We all know Andy does not drink and he has an eye that sees things many people do not. Chris needs to see not just look.
Haiti does not need saved, it needs jobs. The artist of Haiti make all type of wooden curios, but very few things that have functional value. I truly wish the NGO would stop helping them to make more or more crafts.
People buy beer huggers for a reason, this is not a dysfunctional product.
Here is a good page of mine, where I collect business ideas that need to travel to other parts of the planet.
