"When a hot body core issues a command to open the radiators and dump heat, the palm can override that command and order the radiators to shut down based on local conditions, i.e., if the palm touches a cold surface" - Damn, I was thinking that you could cool down by touching anything cold, apparently that won't work because the radiator shuts down if the outside conditions are too cold (so touching ice won't work)... Pretty interesting research, though - implementing something like this in some sort of "power suit" would be great.
