An Extremely Cost Efficient
Solar Powered Water Purification System
For Small Community, Village and Relief Applications.

PROPOSAL

David Wetzel, Lodestone Engineering - Principal

Executive Summary

The recent mega disasters that are plaguing our globe have moved Lodestone Engineering to provide its expertise in solar powered water purification systems through licensing of its technical expertise and technology. The Licensees will include private individuals, commercial enterprises, NGOs and/or governmental agencies. The intention is to provide low-cost, high-efficiency, durable water systems to relieve short-term water crisis and long term solutions for a pure and steady water supply in regions of need. The Living Water Solar System (LWSS) can be produced in volume on-site by the local population and be brought on-line to produce high quality drinking water within a matter of days. While providing short-term relief, the proposed units would also provide long-term, low-cost potable water in an in situ setting suitable for villages and small communities in remote areas, while augmenting municipal systems in urban communities.
Lodestone proposes to provide immediate technical assistance and direction to establish low-cost manufacturing of its solar powered water distillation systems in any region of need to the indigenous populations. The LWSS (Living Water Solar System) consists of a passive, four part system: a molded concrete thermal collector; a black liner; a glass condenser plate; and seal. All materials are globally available at low cost.
Our motivations are driven by humanitarian concerns. We seek to provide services backed by proven technologies, patented and improved upon by Lodestone's proprietary research and development, and to support widespread implementation of LWSS systems throughout the regions in need and eventually the entire world. Each mold, with moderate care, will produce up to 2000 water distillation units or more. By the end of the molds' useful life, this translates to about 2000 gallons per day for what could be a lifetime or more.

LWSS Costs:

Unit costs will vary based upon the volumes of material purchased. The following costs per part are reasonable as of January, 2005, in the Western United States. Given the ready availability of concrete, glass and gasket materials, costs in developing countries are expected to be equivalent or less.

• Concrete: ~90 pounds ~$12.00
• Liner ~$27.00 ~ea. (1,000 unit order, FOB Los Angeles)
• Seal ~$1.00 ~ea. (1,000 unit order, bought in bulk)
• Glass Cond. Plate ~$18.00 ~ea. (low-Iron)
• Tubing ~$1.00 ~ea.
• Tooling Amortized ~$1.00 ~ea. (assumes 2,000 parts per $2,000 production mold)
• Total ~60.00 ~ea.
• Tooling Costs:
• The following tooling costs will be realized:

1st. Objective

Low Volume Epoxy & Fiber Molding
• Immediate First Phase, can be achieved within 3-5 months of order:
• (A) Temp Tooling to make product molds: 1st(Epoxy) $8,860. -
• (Limited life expectancy 1, Master + appx. 50 molds)
• (At a rate of One Unit Per Mold, Per Day.
• Multiples Molds will be required.) Subsequent $2,800
• Cost of Thermal Collector Molds (Epoxy & Fiber) $2,400
• Cost of Thermal Collector Molds (Polyester & Fiber) $1,600 -
• (B) Production Thermal Collector Molds: (Aluminum) $20,000 -
• Production Tooling to For Lners: (First Aluminum) $20,000 -
• Production Liner Molds, Subsequent (Aluminum) $6,000
• Minn. Order of 200 Liners @ $27. ea. $5,400 -
• Total for First Phase First Run $55,860 - 1
• Marketing, Promotions, Salaries and Sales Per Mo. 6K
• $6k. X 12 $72,000 - 2
• By End of First Year $127,860 - 3
• Plus "Subsequent"

2nd Objective

High Volume Injection Molding
• Second Phase, a longer lead time is required from 6 to 9 months:
• Hard Tooling to make production molds: Appx. $280,000 (appx.)
• Product Thermal Collector Molds (Injection molded) @ $200 ea. -.
• or less (appx.) (Compare to $1,600 for Poly & Fiber @ 1,600 ea.)
• Hard Tooling to produce required liners: $20,000 One time only.
• Minn. Order of 200 Liners @ $27. ea. $5,400 -
• $305,600 - 1
• Marketing, Promotions, Salaries and Sales Per Mo. 6K
• 6k. X 12 $72,000
• High Production Total $377,600 - 2
• Plus "Subsequent"
• Immediate and Long Term Combined Total $429,600 - 3

For a small investment of less than $1/2 million the pay back will be the production of
millions of gallons of pure drinking water every year
for generations to come.

• Mold productivity: Concrete bases per mold-life: 2,000 parts
• 2,000 bases @ $2,000 = $1. amortized cost
• Thermal Collector Molds:
• Thermal Collector Molds will be provided at cost plus S&H to site Licensees only.
• Liners: Required liners will be provided in quantities to Licensees only at a nominal profit.
• Estimated Cost of Water from LWSS Unit:
• LWSS production life: ten (10) years
• Production rate: one (1) US gallon per day
• Molded cost: Appx. $55. USD
• Output over Life: 3,650 gallons 3,650/27.0= cost per gallon of $0.007 USD
• Output First Year: 365 gallons 365/27.01= cost per gallon of $.07 USD
• Output Second Year: 730 gallons 730/27.01= cost per gallon of $.036 USD
• Output Fifth Year: 1,825 gallons 1,825/27.01= cost per gallon of $.015 USD
• Output After Amortization 365 gallons per unit per year cost per gallon of $.001....USD

• Assuming a conservative Goal of 2000 molds per tool X 2000 units per mold, = 4,000,000 units X 365 = 1,460,000,000 gallons per year, for an initial investment of $226,600 which translates to
• enough drinking water to serve 16,000,000 people at a total investment of less than one half of a million dollars, or $5.64 per person and no energy costs for a lifetime of pure drinking water. Having an average income of only $2.00 per day it will take just 2.5 days per person to pay off. Once in a lifetime.

3nd Objective

4th Objective, The Main Event:

Development of The Utility Scale Sea Water Desalination Plant System.
