Humanity and Science
We have made some exceptional scientific
advances in the last decade and some of them -
they are not as spectacular as the man-in-space,
but are important If we could ever
competitively, at a cheap rate, get fresh water
from seawater, that would be in the long range
interests of humanity and would dwarf any
other scientific accomplishment.

RO vs FTC

• RO
• Removes water from contaminants
• Requires expensive high pressure plumbing and
  pumps
• Frequent cleaning of membranes by chemicals
• High percentage of water wasted
• Difficult to operate

• FTC
• Removes contaminants from water
• Lower costs
• Uses less energy
• Wastes significantly less water
• User-friendly, easy to use

13
Cost Advantage

• Projected cost of desalinating seawater
  (35000ppm) using FTC
• Total of 0.29 per cubic meter
• 0.12 of which is energy (electricity) cost based
  on 0.035 per KWH
• 0.17 is for depreciated capital
• Unit cost is 453/Liter/min
• For 42,000ppm the numbers are
• 0.33, 0.15,0.18 and 480
• 1 gallon US, liquid 3.7854 liters

Large scale sea water cost is projected assuming
lowered cost as a result of volume manufacture of
both smaller scale sea water and large to small
scale brackish water products.
