Just a few minutes ago I heard about a couple of stories online. Both have to do with getting water, How to Condense Water about a new technology that can draw water from low humidity atmospheres, and Seawater Into Drinking Water—another new technology — about filtering out salts etc. from seawater. This has potential.
The first tech can only draw about 20% of the available humidity from the air. The test kit can at best produce just 3 quarts over a 12 hour period, but keep in mind that the machine used doesn’t look all that big. Scale it up and you can expect greater production.How much potable water the second tech can
How much potable water the second tech can produce isn’t specified, but it appears to be a fair amount. The article also says that the researchers will need to scale things down so the machine in question will be more efficient in filtering the water. But by linking a number of such filters together you could very well produce a lot of fresh water.
In both cases you can expect this new technology to substantially change the world we live in. In the first case the humidity has to come from somewhere. The term relative humidity has to do with how much water the atmosphere can carry in a particular location. In the long run the device will reduce the relative humidity, meaning less chance of precipitation. It also means that the air becomes light and rises, allowing the heavier, moister air around it to displace it. That means a breezier local environment. In fact more winds over all and drier air outside the arid regions. That, in turn, will mean greater evaporation from bodies of water as the current water vapor over the lakes, seas, and oceans get drawn away allowing sunlight to evaporate even more — a case of relative humidity once again.
The second device means that getting fresh water from seawater becomes a lot cheaper. Given the smaller size of individual units installations don’t have to be big expensive operations, and that means smaller communities will be able to build water purification plants to help supplement what they get from precipitation etc. At this moment San Diego County has a water conversion plant under construction. It may well be obsolete before it is ever completed, and may even be dismantled to be replaced by the new tech.
And then you have the fact that the new filter can rid water of other things besides salt. Organic matter, metals, and so on and so forth. With this new filter we’ll be able to cleanse sewage and make the water potable again. Sewage treatment will become cheaper, and very likely a local operation handled by different municipalities. Picture an upriver town cleaning up the water it sends down to a downriver town, meaning that the second location no longer has to use special expensive measures to ensure they have clean water. Aquatic parks and the like will be better able to recycle what they use, making more water available for use by other industries, agriculture, and people.
Picture beachside communities running water conversion plants pumping up water from the sea or ocean. Heck, picture individuals doing the same even should the local water be brackish or alkaline. Watch as the price of water treatment drops and the need to import fresh water from far away drops drastically. At the moment the Colorado river doesn’t always reach the Sea of Cortez. Should the need for Colorado water drop you can expect the flow to reach the sea. That is going to change the local environment up and down the river, and could very well change it as freshwater changes the composition of the seawater due to the restored outflow.
Last, but certainly not least, consider how this new technology is going to affect construction and employment as new plants and installation are built. Local infrastructures are going to change as sewer and water lines are rerouted, or even reversed. Hell, miles of pipelines bringingfresh waterr from elsewhere may even become available for other duties. We may well sea a drop in the price of steel
There’s likely more I can talk about, but now I’m drawing a blank. Have you any ideas you’re welcome to share them.
