-- The power radiator fuctions like an inductive charger
-- only better in the game setting.
-- The purpose is to allow small appliances to receive power
-- without the overhead of the wiring needed for larger machines.
--
-- The power radiator will consume power corresponding to the
-- sum(power rating of the attached appliances)/0.6
-- Using inductive power transfer is very inefficient so this is
-- set to the factor 0.6.
-- API for inductive powered nodes:
-- Use the functions below to set the corresponding callbacks
-- Also two nodes are needed: The inactive and the active one. The active must be called <name>_active .
-- Register a new appliance using this function
