Introducing the new Wolfgang Puck self-heating coffee containers that took 10 years and $24 mil to develop. Great photos.

Once activated, they reach 145 degrees in about 6 minutes. This isn’t a review of the beverage, it’s all about the stuff that makes the liquid hot, how it works, pictures and links to patents….

The self-heating cans are made by a company called OnTech. Their technology section talks a it about how their heating works.

The OnTech self-heating container is built from two main parts: the container and the actuating “puck.” The container is composed of an inner cone that holds the mineral (Calcium Oxide), and the outer container body, which holds the beverage product. The puck holds water and is sealed by a foil membrane. All components are made from FDA-approved materials.
