| ee0765 | 1 | -- The power radiator fuctions like an inductive charger |
| S | 2 | -- only better in the game setting. |
| 3 | -- The purpose is to allow small appliances to receive power | |
| 4 | -- without the overhead of the wiring needed for larger machines. | |
| 5 | -- | |
| 6 | -- The power radiator will consume power corresponding to the | |
| 7 | -- sum(power rating of the attached appliances)/0.06 | |
| 8 | -- Using inductive power transfer is very inefficient so this is | |
| 9 | -- set to the factor 0.06. | |
