14. LITERATUREREVIEW
•The concept of underwater windmills, also known
asmarine or hydrokineticturbines,isdiscussedin
variousacademicjournalsandpublications. One
notablereferenceisthe book“MarineRenewable
Energy Handbook”editedby TrevorM. Whittaker
and SteveH.Wright.Specifically,underwater
windmillsarecoveredinthechapter titled
“MarineCurrentandTidalStreamEnergy.”This
bookprovidesacomprehensiveoverviewof
