Phase Change Capsules in Drywall

What a great idea. Daytime heat is absorbed into little capsules of a material that changes phase. The material is mixed into drywall plaster. Rooms stay cool. At night the heat is released. Great primary function, but the material is made from a process that coats Paraffin wax. I have to wonder how that does for fire resistance.
