Producing Clean Power in the Absence of Water via @reworld

Every manufacturing process requires heat to produce materials and goods. And the cheapest and fastest way to cool that heat down is through water; more specifically, steam generation. The good news is that all of the fast moving water that’s heated to steam flows through a turbine generator and actually produces energy that is fed back into the process. This is known as a condensing turbine, which uses steam to recover energy. The bad news is that according to the U.S. Geological Survey , almost 2,300 gallons of water are wasted for every megawatt hour of energy generated. Fresh water is one of our planet’s scarcest natural resources. According to the National Renewable Energy Lab, thermoelectric power alone accounts for 39 percent of all water consumption in the U.S. , consuming over 200 million gallons per day. And the majority of that water is used to cool our heated p...
