I have conceptualized a floating condenser which uses the oceanic thermocline as a heat-sink.
The condenser derives 100% of the electricity needed to power it from ambient wind. It uses the Coanda effect as a wind speed amplifier. The system would work most efficiently along coastal deserts with cold ocean currents such as California, SW Africa and Chile. Such condensers might cost $80,000 per copy and might
generate 10-20 metric tons of freshwater per day. The construct is low tech.
If you are interested I will send you a description of the condenser.
