Abstract
The present invention is a DC power system incorporated into a modular housing. The primary source of power is an electrical utility. Because the electrical utility provides alternating current, the module includes a rectifier which makes the conversion to DC. The module also includes an air turbine which is used as a backup source of power. Also included is an array of lithium-metal-polymer (LMP) batteries to bridge and also for backup power if necessary.
