Habitable shelter is a common need throughout the world. The ability to provide water and power infrastructure to support large amounts of shelters may not be practical, available, or in some instances, desired. For example, large amounts of displaced refugees due to natural or man-made disasters results in an immediate need for habitable shelters. The water and power infrastructure to support that need may be unusable or may not even exist. Habitable structures that are easy to assemble and can be quickly delivered are desirable in responding to a humanitarian crisis. Even under normal (non-crisis) conditions domiciles that are self contained or self sufficient may be desirable due to, for example, remote location, unreliable delivery, of power water, or limited waste disposal options.
Without an existing utility infrastructure, the ability to provide water and power for individual shelters is problematic. Power provided by gasoline generators requires constant replenishment and an electrical network to provide power to individual shelters. Water provided by truck requires individual occupants to wait in line to receive water and limits their amount of water based on what they can carry back to their shelter.
This Summary is provided to introduce simplified concepts for an off-the-grid container shippable domicile that provides water and power without being connected external utilities. The habitable shelter may, but need not be connected to a utility grid for water and power. The methods and systems are described in greater detail below in the Detailed Description. This Summary is not intended to identify essential features of the claimed subject matter nor is it intended for use in determining the scope of the claimed subject matter. One or more other renewable energy sources may additionally or alternatively be provided, such as wind, geothermal, or the like.
The off-the-grid capabilities may include the use of a low power direct current electrical system for the habitable structure. Various low power energy storage devices can be stored in the house to provide power to the appliances and outlets included in the structure. Additionally, a solar power collection device can be used to supplement the energy storage devices or provide the primary source of power for the structure.
A water storage system for the structure may include bladders or other liquid-tight flexible containers that deliver potable water and collect gray water. A composting system may also be included to process any bio-degradable waste generated by the occupants of the structure.
The structure may also be substantially prefabricated to include the walls, floors, appliances, power and water distribution systems, and fixtures that may be included in any home or building. Further, in some embodiments, the structure may be shipped in a collapsed state that permits the entire structure to be shipped in a shipping container. Once the shipping container reaches its final destination, the collapsed structure can be removed from the container and converted to an expanded state that provides a habitable space that does not require connections to external fixed utilities for water, power, or fuel.
The Detailed Description is set forth with reference to the accompanying figures. In the figures, the left-most digit(s) of a reference number identifies the figure in which the reference number first appears. The use of the same reference numbers in different figures indicates similar or identical items.
This disclosure relates to a habitable structure whose power and water supply is internal to the structure. In another embodiment, the structure may be a prefabricated structure that includes appliances and fixtures that may be assembled on site. Additionally, the habitable structure can be prefabricated into a collapsed state that permits the structure to be shipped in a standard shipping container. Once the prefabricated structure arrives on site, the structure may be removed from the container and expanded to provide habitable shelter for any occupants.
In one implementation, a prefabricated structure may be shipped in a collapsed state that enables the structure to be placed in a standard shipping container. Following removal from the shipping container, the structure may be assembled using the prefabricated components that incorporate electrical, water, and composting systems to provide a habitable structure that does not require connection to external utilities. Although external utilities are not required, the habitable structure may be configured to interface with external utilities if desired.

In one embodiment, the solar energy collection cells 500 are integrated on to an end of a tube 502 that is coupled an opening in the roof 504 of the prefabricated structure 100. The tube 502 protrudes down to an interior habitable space 506 of the prefabricated structure 100. For example, the living area 244 would be a portion of the interior habitable space 506. Although tube 502 is shown as being straight, it could also bend or curve to direct natural light into the interior spaces. The end of the tube 502 protruding from the opening of the roof 504 may include a translucent or transparent dome 508 that covers the end of the tube 502 and the solar energy collections cells 500 that are arranged around the end of the tube 502. A light globe may be coupled to the opposite end of the tube 502 that protrudes down to the interior habitable space 506 to diffuse natural light into the space during the day. In one embodiment, the light globe may include a translucent dome 510 and an arrangement of lights 512. The lights 512 may include light emitting diodes or any other low voltage direct current light emitting devices. In this embodiment, during the day sun light 422 passes through the dome 508 down through the tube 502 and into the interior habitable space 506. The solar energy collection cells 500 intercept a portion of the light 422 and convert it into electricity that is stored in the energy storage device 418. The stored energy is then used to power the lights 512 at night.
In some embodiments, tube 502 includes a dimmer device 514 or variable light baffle incorporated within the interior volume of the tube. The dimmer device 514 may be configured to block the light 422 from reaching the interior habitable space 506. The dimmer device 514 may include a rod 516 that has both ends coupled to the interior surface of the tube 502. The rod 516 may be coupled to a circular flap 518 that blocks the light from travelling through the tube 502. In the 90 degree cut-away illustration 520 of the dimmer device 514, the rod 516 is located off the vertical center line of the tube 502. When the flap 518 is in the vertical position 522, this enables a large amount of light 422 to reach the interior habitable space 506. In contrast, when the flap 518 is in the horizontal position 524 a lower amount of light 422 reaches the interior habitable space 506. The position of the flap 518 is variable and may move within a 90 degree arc between the vertical position 522 and the horizontal position 524 enabled by an actuation device 526. Alternatively, other light blocking means (e.g., blinds) could be used.
