-- only better in the game setting. |

-- The purpose is to allow small appliances to receive power |

-- 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. |
