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

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.

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