The American Society of Mechanical Engineers (ASME) recently published an article featuring insights from Ecotech Institute’s renewable energy instructor Dan Fink.
The article discusses various renewable energy technologies that, for one reason or another, have not yet received wide implementation in the United States.
One of such underutilized clean energy technologies highlighted by Fink, is solar thermal energy collection and storage with the use of thermosiphons.
Usually installed on rooftops, with a series of parallel metal pipes leading up to a cylindrical water tank, thermosiphons use the heat coming from the sun to provide residents with hot water around the clock at virtually no cost.
Thermosiphons were quite common in the United States in the early 1900s, says Fink. However, due to electrification and the rise of the oil and gas industry in California, this technology was soon replaced by carbon-based energy sources.
However, that has not been the case in many other countries around the world, Fink notes. For instance, thermosiphons are widely used in China, where they provide cheap and emissions-free hot water for the country's rapidly growing urban population.
Such systems could find many great uses in the Unites States as well, notes Fink, especially, in rural and remote areas where grid power is often non-existent.
