Keith, Per our discussion, I have these emails to submit to the Biofuels forum.
These are a series of emails that I had with Stuart Hoernig on his concept of de-humidifying air with electrostatics. They read in reverse order. Stuart was kind enough to FAX me two pages which were the basis for his concept. I reviewed them and sent my comments back to him. He has chosen to stop further communication on the subject. I have designed several high voltage Cottrell Precipitators which successfully collect particulates from the air. We have been able to collect droplets but not unless they have condensed into droplets in the airstream due to saturation. Unsaturated vapors pass right through the unit without agglomerating. I look forward to the potential of seeing these items on the market but I am not looking too hard. Art Krenzel, P.E.

Hopefully you will see some of our inventions on the market on Phoenix by the end of the year. Stuart A. Hoernig Stuart, You mentioned the obvious - that air moving across a lake can increase the water evaporation by a factor of two. What was not obvious in your presentation was that the lake was at 50 degrees centigrade (see graph data). The vapor pressure of water at 20 degrees C = 17.5 mm Hg. The vapor pressure of water at 50 degrees C = 92.51 mm Hg. The vapor pressure is 5.3 times greater at 50 degrees C than at room temperature. Would you not expect water to evaporate at least five times faster with a five fold increase in vapor pressure when you agree that wind alone doubles the evaporation rate?? Electric wind velocity is proportional to voltage applied so you can generate nice graphs such as you presented when you compare evaporation rate vs time. >> You said, "In normal evaporation many of the drops go back to the liquid >> phase, if the drops are evaporated electrostatically they will have a charge >> and will be repelled by the surface with has the opposite charge." In my world, opposite charges attract each other. >>You said, "Last but not least the droplets evaporated from salt water are >>fresh, this has been understood for some 75 years. Where do you think CA gets >>all its water---rainfall." Yes, CA gets rainfall which comes from condensed water VAPOR from the ocean. The vapor stage leaves behind all the solids which you are proposing to collect the droplets with. Unless you have severely acid rain, water vapor is more of an insulator when it comes to collecting a charge. That is why thunderstorms can generate incredible voltages per meter and store such high energy fields in the clouds. If the clouds had high conductivity such as the ions you propose, lightning would not be generated in such huge bursts of energy. I think this subject needs some better review. Art Krenzel, P.E.

You do not evaporate all the salt water only about 10-15 percent of it. The rest goes back to the ocean. Air moving across a lake does increase the rate of evaporation, this has been measured and at most it is a factor of 2. In normal evaporation many of the drops go back to the liquid phase, if the drops are evaporated electrostatically they will have a charge and will be repelled by the surface with has the opposite charge. Last but not least the droplets evaporated from salt water are fresh, this has been understood for some 75 years. Where do you think CA gets all its water---rainfall.
