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

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-H_{2}, or Metric Tonnes of Ammonia.

Working backwards from cell B21, price per metric tonne NH_{3}, 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.
