| 1. A plant for producing low-deuterium water from seawater comprising:
A) a solar still comprising:
1) a black pan for absorbing radiation from the sun and transferring resulting solar heat energy to seawater to evaporate
the seawater to produce water vapor,
2) a condensate tank,
3) a porous membrane, defining an upper side and a lower side, and positioned above said black pan for condensing said water
vapor into a condensate,
a) comprising diffusing pores permitting said condensate to diffuse from said lower side to said upper side, and
b) being positioned in a slope to permit said condensate on said upper side to drain into said condensate tank, and
B) a water treatment unit for reducing deuterium concentration in said condensate comprising:
1) a water filter to produce filtered condensate,
2) an electrolizer for separating a portion of said filtered condensate into hydrogen and oxygen,
3) a reactor for combining at least a portion of said hydrogen and oxygen to produce heat and water having deuterium concentrations
at least 50 percent lower than deuterium concentration in natural seawater, and
4) a heat transfer system to transfer heat energy produced in said reactor to said reactor to provide heat energy to supplement
said solar heat energy.
