Desalination Project Background

A patented and tested technology using solar/geo-thermal energy to desalinate seawater

  • A 99% "Green" project
  • Energy derived from solar/geo-thermal sources
  • Result of 30 years of independent research
  • Thermal process patent issued in 2003
  • Technology licensed to TransGlobal Water
  • Immune to fluctuations in fossil fuel prices
  • Projected to be much less expensive than reverse osmosis, the main competition

Worldwide Water Supply

Water scarcity

Water scarcity in South Africa

Implementation Plan

  • Locate financial partners
  • Construct field scale pilot plant under auspices of project leader and team
  • Calibrate and test pilot plant
  • Obtain accurate cost of water numbers
  • Work out details of supply chain and distribution to customers
  • Contact potential first customers

Analysis of Market Strength

  • 1.8 billion people worldwide experience regular water shortages*
  • Will increase to 2.5 billion in ten years*
  • Global market for new desalination systems will be $100-300 billion over next 15 years*
  • 75 countries experiencing current severe water shortages; number projected to double within 15 years*
  • Four counties in Southwest Florida represent a $7 billion dollar market for new water over next 15 years
  • Desalination is the only remedy

*Tampa Bay R.O. plant claims to have the lowest cost of production numbers in the world, but has been plagued by start up problems.

Comparison of Desalination Processess

TGWR Thermal Desalination
Can be 100% sustainable; completely free of fossil fuel based price volatility
Long effective life span of production plants; simplicity of operation
Distillation Desalination
Operated in OPEC nations where oil and natural gas can be used to fire the boilers to produce freshwater; too expensive for widespread application
Reverse Osmosis Desalination
Requires large amounts of electricity to operate. Costs of water connected to volatile fossil fuel prices

Desalination Costs

Energy Consumption Comparison: TGWR vs. Reverse Osmosis

TGWR
Uses no fossil fuel generated electricity
By combining solar, geo-thermal and wind energy the system can be 100% sustainable
Reverse Osmosis
Uses 22.7 tons (45,400 lbs.) of coal to generate enough electricity to produce 1 million gallons of water (supply for 12,550 people per day)
Coal burning is responsible for:
  • 63% of sulfur dioxide emissions
  • 22% of NOx emissions
  • 39% of carbon emissions that contribute to global climate change
  • 33% of mercury emissions
