Freshwater, drought, and climate change

Lack of freshwater for human consumption and agricultural use is a growing and very serious problem globally–including in rich countries like the United States.  As an example, rivers in many countries are experiencing significantly reduced flows due to warmer temperatures, longer and more frequent droughts, less snow and less winter precipitation, and the need to serve more and more people. Quick bibliography: Recent research about…

Advances in solar water purification

News: Here is some potentially very positive news … It’s estimated that nearly 800 million people globally today lack access to safe drinking water–that’s not positive; it’s a huge, dangerous problem. Existing technologies “for purifying contaminated water and desalinating seawater” often are very expensive and use large amounts of energy–beyond the ability of many communities to put into place. Solar stills are an existing lower-tech…
