Abstract

An electrolytic device and method for generating a disinfecting solution that utilizes a brine generator, an electrical circuit with an on-board solar panel and rechargeable storage battery. The electrical circuit preferably conditions the power received from a variety of power sources to charge the storage battery and conditions the power stored in the storage battery to provide the appropriate power to maximize the disinfection efficacy of the disinfecting solution. The on-board solar panel and/or rechargeable battery can be utilized as the power source to recharge or operate other devices such as cell phones, PDAs, flashlights, GPS systems, or other such devices. The device can incorporate a touch screen display and electronics that is an electronic “water finder” application for locating sources of water that can be made potable. The device can incorporate a biocidal agent and foul resistant water filter that can be folded up to provide a compact configuration for storage.

Claims

1. An apparatus to facilitate production of potable water, comprising:

(a) an electrolytic cell configured to generate oxidation/reduction products, at least a first product of which is suitable for disinfecting water;

(b) an electrical system configured to supply electrical power to the electrolytic cell for at least one of (i) a predetermined time, or (ii) until activity in the electrolytic cell indicates that a desired quantity of the first product has been produced;

(c) a housing in which the electrolytic cell and electrical system are mounted.

2. An apparatus as in claim 1, further comprising a filter suitable for filtering water, wherein the filter is mounted with the housing.

3. An apparatus as in claim 2, wherein the filter is mounted with the housing with a removable mounting relationship between the filter and the housing.

4. An apparatus as in claim 2, wherein the filter comprises a sheet prefolded such that it can be configured to a substantially flat configuration and to a configuration that contains a volume of water to be filtered.

5. An apparatus as in claim 2, wherein the filter comprises a hydrophobic material.

6. An apparatus as in claim 2, wherein the filter comprises a biocidal substance.

7. An apparatus as in claim 1, further comprising a display system configured to communicate to a user of the apparatus information concerning the location of water sources near the user.

8. An apparatus as in claim 7, wherein the display system comprises a programmed data processor that identifies water sources to display based on proximity to the current location of the apparatus.

9. An apparatus as in claim 7, wherein the display system further comprises a communication subsystem configured to accept from external sources data concerning water sources.

10. An apparatus as in claim 9, wherein the data concerning water sources comprises data concerning one or more of (a) the location of a water source, (b) the volume of water at a water source, (c) meteorological occurrences in the area of the water source, (d) experience of other users in accessing the water source.

11. An apparatus as in claim 7, wherein the display system further comprises a global positioning system received configured to determine the current location of the apparatus.

12. An apparatus as in claim 1, wherein the housing defines first and second sealable reservoirs and a path allowing fluid to flow between the first and second reservoirs, wherein the fluid path is configured such that fluid can flow through the fluid path when the apparatus is in a first disposition relative to vertical and such that fluid does not flow through the fluid path when the apparatus is in a second disposition relative to vertical, and wherein the first reservoir is a fluid container for the electrolytic cell.

13. An apparatus as in claim 1, wherein the electrolytic cell comprises a first sealable reservoir, and wherein the apparatus further comprises a second sealable reservoir suitable for containing halogen salt such as sodium chloride, wherein the first and second reservoirs are connected by a fluid pathway configured such that fluid in the second reservoir flows to the first reservoir when the apparatus is in a first disposition relative to vertical and does not flow to the first reservoir when the apparatus is in a second disposition relative to vertical.

14. An apparatus as in claim 1, wherein the electrolytic cell comprises a first sealable reservoir, and wherein the apparatus further comprises a halogen salt containment reservoir, and wherein a fluid path connects the first reservoir and the salt containment reservoir, wherein the fluid path is configured such that, when the apparatus is in a first disposition relative to vertical, gravity causes fluid to flow from the first reservoir to the halogen salt containment reservoir;

and when the apparatus is in a second disposition relative to vertical, gravity causes fluid to flow from the halogen salt containment reservoir to the first reservoir.

15. An apparatus as in claim 14, wherein the fluid path is further configured such that, when the apparatus is in a third disposition relative to vertical, fluid does not flow between the first reservoir and the halogen salt containment reservoir.

16. An apparatus as in claim 14, wherein the first reservoir defines a fluid chamber characterized by a top and bottom when the apparatus is held such that an axis of the apparatus is vertical, and wherein the fluid path is configured such that, for at least a portion of the fluid path, the lowest surface of the fluid path is above the top of the chamber when the apparatus is held such that the axis is vertical.

18. An apparatus as in claim 1, wherein the electrical system further comprises a solar power generation device.

24. An apparatus as in claim 18, wherein the solar power generation device comprises a plurality of solar panels, mounted in a foldable relationship.

26. An apparatus as in claim 1, further comprising a separable brine compartment.

17. (canceled)

20. An apparatus as in claim 17, wherein the electrical system further comprises a connector configured to allow energy from the device to supply energy to a load external to the apparatus.
