That part was simple; just a matter of circulating water through hot or cold packs. What I'm trying to do now is to fine tune the response areas. It will be useful for making synthetic reality suits.
It means using thermoelectric materials, so that current in one direction produces heat, and reversing it produces cooling.
Once my technical upgrades are completed, you will be able to use your suit to simulate walking through a forest glen, or unintentionally stepping into a rivulet or stream.
I think Clive Cussler has something like it for his NUMA crew. Check out NUMA.net.
Are all those currents a good thing to be covering our bodies with?
