   Wind hindcast maps from NASA above indicate a favorable capacity factor for hydrokinetic and wind hybrid energy conversion modules over a vast region of the Southern Indian Ocean from Madagascar to Perth, Western Australia. According to NASA Visible Earth Global Wind Speed data, this vast region sustains wind speeds averaging 11.5m/s or 22.4 kts.

   The Integrated Power Technology Corporation™ proposes deploying a fleet of Turbofoil® equipped vessels configured with 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 Turbofoil® Feasibility 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® in the Southern Indian Ocean


Feasibility of Grid Feed-in from a Turbofoil® in the Southern Indian Ocean


Integrated Power Technology Corporation™ Turbofoil® Feasibility in the Southern Indian Ocean   The Feasibility of Grid Feed-in from a Turbofoil® in the Southern Indian Ocean spreadsheet determines a 13.1% 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 6.45% 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 Southern Indian Ocean Grid Feed-in Spreadsheet cells are determined as follows:


Feasibility of H2 (kg) from a Turbofoil® in the Southern Indian Ocean


Integrated Power Technology Corporation™ Turbofoil® Feasibility in the Southern Indian Ocean   The Feasibility of H2 (kg) from a Turbofoil® in the Southern Indian Ocean spreadsheet determines an 4.2% operating margin for a $6.5M vessel financed at a 10% annual rate over a ten year term, delivering H2 at $3.50/kg, given the NASA data applied to the Exponential Wind Gradient Model as described above. The parameters input to the Southern Indian Ocean H2 (kg) Spreadsheet cells are determined as follows:


Feasibility of Ammonia from a Turbofoil® in the Southern Indian Ocean


Integrated Power Technology Corporation™ Turbofoil® Feasibility in the Southern Indian Ocean   The Feasibility of Ammonia from a Turbofoil® in the Southern Indian Ocean spreadsheet determines an 36.3% 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 Southern Indian Ocean 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 $385/Mt with all other parameters remaining unchanged and a Turbofoil® in the Southern Indian Ocean 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 $12M 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 29.3 miles/hour or 13.1m/s, at today's ammonia spot price with all other parameters remaining the same.
