Could be generating electricity directly from beta decay. Still have to 
watch out for heat generated due to inefficiencies in the process, but 
if you assume efficiency is part of the device's hypothetical abilities 
you can move most of the heat out to whatever mechanisms are using the 
power rather than boiling Stark's chest cavity.
