100Kgph = about 27 gallons = about 100 litres which is a small amount for 12 square meters of deck space.

The cost of electrical generation with a low temperature turbine could be very high. What sort of turbine do you have in mind?

steam turbine can be use plastic.

without turbine, it can produrce 250Kgph 55 degree fresh water or 400Kgph 40 degree fresh water.

Heat engine efficiency is directly related to I/O temperature difference. What do you calculate for conversion efficiency with such a small temperature difference?

Are your temperatures in Fahrenheit or Celsius?

the temperature of 1 Kg seawater rise 1 Celsius, it need 1Kcal.

Normal seawater is 15 Celsius, if the temprature of 500Kg seawater rise from 15C to 35C, then 10000Kcal heat is needed.

It is the maximal output of the fresh water, the real time is 60-70%.

Not me, waveless: "Yes, the vapor that temperature less than 100 degree is called steam".

What I think is another thing alltogether as you would probably realised by now from his mathematics.

To many perls to address them all. But it's a lot of fun to read.
