The Tacoma Narrows

• Bottleneck of ocean separating Puget Sound north
  and south 1.5 2 km wide, 100m deep, 4 km
  long, currents 2 m/s 4-6 knots peak.
• City of Tacoma 200k people
• City of Tacoma Public Utilities dba Tacoma
  Power
• Renewable power portfolio now required by law
• Its obvious to 90k cars/day on the Bridge the
  Narrows has power
• EPRI estimates that 15 power extraction
  120,000 MW
