Editing Geothermal desalination (section)

== History ==
The exact origins of geothermal desalination are unclear; however some early work is credited to Leon Awerbuch, a scientist working in Research & Development at the [[Bechtel Group]] at the time, who proposed the process of using geothermal energy for water desalination in 1972.<ref>{{Cite web |title=Mr. Leon Awerbuch |url=https://idadesal.org/profile/mr-leon-awerbuch-2/ |access-date=2022-11-01 |website=Idadesal |language=en-US}}</ref><ref>{{Cite journal |last=Kalogirou |first=S. |date=2005 |title=Seawater desalination using renewable energy sources |url=https://www.academia.edu/531518 |journal=Progress in Energy and Combustion Science |volume=31 |issue=3 |pages=242–281 |doi=10.1016/j.pecs.2005.03.001 |issn=0360-1285}}</ref> In 1994, a prototype that used geothermal energy to power desalination was built by Caldor-Marseille.<ref name=":32">{{Cite journal |last1=Bourouni |first1=K. |last2=Martin |first2=R. |last3=Tadrist |first3=L. |last4=Chaibi |first4=M.

Its capacity was three cubic meters of water per day, which could meet the needs of the surrounding communities. The cost of water was estimated to be $1.20 per cubic meter.<ref>{{Cite book |last1=Bourouni |first1=K. |last2=Tunisia |first2=Tunis |last3=Tunisia |first3=Ariana |date=2005 |chapter=Application of Geothermal Energy for Brackish Water Desalination in the South of Tunisia |title=Proceedings World Geothermal Congress 2005: Antalya, Turkey, 24-29 April 2005|s2cid=56113741 |language=en}}</ref>
