Impermeable membrane
Example Floating Field design concept
Could we use a semi-permeable membrane, and have a non-plant=toxic solution in it so that it draws water from the sea?

Membrane fields
Floating Fields
Only the edges of a scheme need to be protected from waves.
With the whole water surface covered, waves will not form.
Would need wave breakers on open lake/sea/ocean edges though.
Tides can be absorbed withing the structure
Irrigation can be from freshwater substrate, or piped
Potential for sterile conditions could mean no weeds or diseases
Design of pads to be leak tolerant
Design of pads to minimise instability ( heavy area pulling in more weight)
Floating Fields
Stage 1 Floating on reservoirs
Stage 2 Floating on lakes
Stage 3 Floating on sea at the outflow of rivers
Stage 4 Floating in ocean where rainfall is sufficient
Stage 5 Moving fields according to weather and crop needs
