   The wind hindcast map from AWStruewind.com above indicates a favorable capacity factor for hydrokinetic and wind hybrid energy conversion modules over hundreds of square miles of the Pacific Ocean north and south of the Big Island of Hawaii. According to the AWStruewind.com Wind Speed map above, this vast region consistently sustains wind speeds averaging over 8.5m/s or 19mph. Because the maps do not show how much greater than 8.5m/s these winds are, the Integrated Power Technology Corporation™ will base its feasibility on that conservative estimate.

   The Integrated Power Technology Corporation™ proposes deploying a fleet of streamlined Turbofoil® equipped vessels designed for the wind conditions shown in the above map. Although the Turbofoil® Feasibility Spreadsheets below analyze a turbine gate of twice the area compared to other Turbofoil® equipped vessels deployed in other regions in the configuration geographic database, because of a lower average wind velocity around the Big Island of Hawaii, about half the hydrokinetic power impinges upon the Turbofoil® on the vessels deployed there, hence the "streamlined" description. The lower power requirement likely results in lower capital expenditure for the turbine generators themselves. Nonetheless, we will continue to base our analysis on a $6.5M total vessel cost.

   We must make an important observation regarding both the lower hydrokinetic power and the proximity of an island based central service and distribution center for this operating regime. Because of this resource's proximity to land and with lower hydrokinetic energy due to somewhat lower wind velocity, so much more time will be spent gathering energy compared to Offloading the energy. Around the Big Island of Hawaii in all operating scenarios other than ammonia production, the Offloading time efficiency (%) will likely require approximately less than twenty percent versus one third the time as accounted for with other Turbofoil® equipped vessels deployed in other regions in the configuration geographic database.

   The Turbofoil® equipped vessels will also comprize a parasail. The parasail exploits high altitude winds of substantial force but lower turbulence in stable conditions. Using an Exponential Wind Gradient Model with a Hellman Exponent conservatively estimated at α=0.12 indicates a wind speed at a height of 300m to be 1.32 times greater than at 30m as shown on the map above to obtain the operating margins modeled in the spreadsheets below.

   The Integrated Power Technology Corporation™ has determined the following operating margins modeled in the Turbofoil® Feasibility Spreadsheets below based on delivery of kWh of electricity, kg-H2, or Metric Tonnes of Ammonia.

Feasibility & Break-even Analysis of a Turbine-Integrated Hydrofoil or Turbofoil® Around the Big Island of Hawaii


Feasibility of Grid Feed-in from a Turbofoil® around the Big Island of Hawaii


Integrated Power Technology Corporation™ Turbofoil® Feasibility around the Big Island of Hawaii   The Feasibility of Grid Feed-in from a Turbofoil® around the Big Island of Hawaii spreadsheet determines a 10% operating margin for a $6.5M vessel financed at a 10% annual rate over a ten year term, delivering electricity at $0.14/kWh or, working backwards from cell B22, setting a wholesale price at $0.13/kWh attains a 3.1% operating margin with all other parameters remaining the same, given the NASA data applied to the Exponential Wind Gradient Model as described above. The parameters input to the Big Island of Hawaii Grid Feed-in Spreadsheet cells are determined as follows:


Feasibility of H2 (kg) from a Turbofoil® around the Big Island of Hawaii


Integrated Power Technology Corporation™ Turbofoil® Feasibility around the Big Island of Hawaii   The Feasibility of H2 (kg) from a Turbofoil® around the Big Island of Hawaii spreadsheet determines an 7.4% operating margin for a $6.5M vessel financed at a 10% annual rate over a ten year term, delivering H2 at $3.75/kg, given the NASA data applied to the Exponential Wind Gradient Model as described above. The parameters input to the Big Island of Hawaii H2 (kg) Spreadsheet cells are determined as follows:


Feasibility of Ammonia from a Turbofoil® around the Big Island of Hawaii


Integrated Power Technology Corporation™ Turbofoil® Feasibility around the Big Island of Hawaii   The Feasibility of Ammonia from a Turbofoil® around the Big Island of Hawaii spreadsheet determines an 20.9% operating margin for a $6.5M vessel financed at a 10% annual rate over a ten year term, delivering NH3 at recent spot prices of $600/Mt (metric tonne) fob, given the NASA data applied to the Exponential Wind Gradient Model as described above. The parameters input to the Big Island of Hawaii NH3 (kg) Spreadsheet cells are determined as follows:


   Working backwards from cell B21, price per metric tonne NH3, the spot price of ammonia can drop to $475/Mt with all other parameters remaining unchanged and a Turbofoil® around the Big Island of Hawaii will remain profitable. Likewise, working backwards from cell D35, the principal of the debt financed mobile structure could go way over-budget as high as $9M at today's ammonia spot price with all other parameters remaining the same and operation remains profitable. Finally we note here one last lesser favorable outcome despite which we continue to profit: working backwards from cell B6, the mobile structure can only attain a velocity of 23.3 miles/hour or 10.4m/s, at today's ammonia spot price with all other parameters remaining the same.
