## Thirty-year history of days with winds greater than 45 knots in the Western Pacific Basin, Source: NOAA's IBTrACS WMO: International Best Tracks Archive for Climate Stewardship -- Version: v03r02 |

The **Integrated Power Technology Corporation™** recently completed a study of thirty years of NOAA hurricane tracking data finding the Western Pacific Basin, "Typhoon Alley", experiences on average 118 days per year with sustained winds greater than 45 knots, about thirty two per cent of the year, normalized to 54 hours per week in operation on average.

The **Integrated Power Technology Corporation™** proposes deploying a fleet of **Turbofoil®** equipped vessels guided towards these storms. In an estimate of any storm originating, on average, within 720 miles from this awaiting fleet, and the fleet capable of 20 knots cruising speed in approach to the storm, the fleet will engage the storm within an average of one and a half days. Accounting for this estimate of logistical inefficiency and an average of 21 storms per year, that leaves 87 days of energy extraction on average. Thus 87 days out of 118 days yields a 74% capacity utilization, and considering that the fleet of Turbofoil® equipped vessels will spend two-thirds of their time during these days actually capturing energy, with the other one-third spent delivering and offloading the energy to the command vessel, hence the Offloading time efficiency (74%x2/3=) 49% number in the Turbofoil® Feasibility Spreadsheets below.

The **Integrated Power Technology Corporation™** has determined the following operating margins 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 $380/Mt** with all other parameters remaining unchanged and a Turbofoil® around Guam and the Philippines 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 $11M** at today's ammonia price with all other parameters remaining the same and operation remains profitable. The **Standard Deviation** for days per year with sustained winds greater than 45 knots is **34 days**. With ammonia at today's prices, a Turbofoil® producing ammonia around Guam and the Philippines will remain profitable down to a standard deviation below average days per year with sustained winds greater than 45 knots, more than 83% of the years in operation.
