Various implementations of a system that addresses the need for clean drinking water, improved solid fuel combustion and convection of the heat resulting from the combustion, exhausting of gases and air-borne particulates resulting from combustion, and provides electricity for lighting and charging of battery-operated devices are described herein. The system may include at least one solar panel, a battery, a fan assisted exhaust hood, a fan assisted cooking device, and a water purification device. Such a device could not only save millions of lives, but the quality of life for millions of people living in impoverished areas or refugee camps could be improved dramatically.

Provided is an air cooled combustion furnace system to effectively operate a combustion furnace for generation of heat energy via combustion of a solid fuel so as to optimize thermal efficiency. The combustion furnace system includes a combustion body structure provided with a hopper and having a combustion space for production of heat energy via combustion of a solid fuel, a cooling device integrally formed in multiple layers with the combustion body structure to cool the combustion body structure via distribution of air, a negative pressure induction device to create a negative pressure within the combustion body structure by suctioning air, a fuel supply device, a grate device constructed by coupling a plurality of grate segments to one another and serving to support the solid fuel being combusted, and a clinker removal device to remove clinkers generated during combustion of the solid fuel from the grate device.
