Talk:Vaccuum Distillation

Already widespread. Lab Scale/Small Scale it can be attached to a (semi-) standard Distillation Apparatus (Although ideally with a Cold Trap + other means to protect the Vacuum Pump , or via a Rotavap . Large scale it can be done in a Multiple-effect evaporator / Falling Film Evaporator or VERY large scale in a Vacuum Distillation Unit

The former is used for delicate samples/products like Pharmaceuticals, Food, and Sensitive Compounds etc

The latter is used to get Heavy Fractions out of the Residuals of a STANDARD Fractional Distillation ( Crude Oil Distillation Unit / Atmospheric Distillation Unit )

So i watched the video, for the most part this would be a mix of a Solar Still and a Multi-Effect Evaporator

There has been some novel work in Solar Still Design recently (mainly in trying to make a better Solar Thermal Absorber Materials )

The benefits of that system, vs a more conventional Solar Thermal Concentrator + Heat Transfer Fluid + Multi-Effect Evaporator system would have to be determined.

Some of these novel setups make sense small scale (Thus potentially Homestead / FeF Scale etc) but above that the novelty vs scalability/Off The Shelf Component aspect + Maintainability etc makes them less viable.

If i remember correctly there is an Open Source Linear Solar Concentrator that makes steam, that and a Skid Mounted Steam Fed Desalination Plant / Watermaker perhaps?

Running a Saltworks would be neat!, but other than that Brine Disposal is a bit of a pain.
