1. Design a system that measures the rate of metabolic heat production of a small warm-blooded animal. You may use either a direct or an indirect calorimetry technique. Provide engineering drawings and instrumentation specifications.
2. Design a whole body calorimeter that measures the instantaneous metabolic heat loss rate from an entire human body. Your system must be large enough or else sufficiently mobile that measurements can be made while the test subject is doing physical labor without restraint from your system.
