New look on power generation by oceans' currents
New look on power generation by oceans’ currents Author: David Judbarovski, system engineering, principle inventor judbarovski@gmail.com Abstract My hydraulic turbine is breakthrough simple and cheap and can save some milliard dollar for Japan annually by extracting 5% power potential of its nearby Kuroshio current. It cost (CAPEX) practically is a total cost of electric generators can be low speed gearless permanent magnet synchronous generator, because the others are relatively negligible. So it is about USD 200-400/kW. Supposing 5 years payback, the electricity cost would be less than one cent per kWh. Really, 8800 hrs. * 5 yrs. * 1.0 kW = 44,000 kWh by USD 200-400. So 0.45 -0.9 cent / kWh Disclosure for technical expert: It is a vertical chain of special units. Each unit is equipped by two electric generators each at its ends and by three vertical plane blades of identical window leaf of thin steel sheet. So the current’s flow rotates the said generators b...
