Wind-Aid
Problem Statement

• Convert wind energy to storable electric energy
• Easily deployable (compact, portable, robust)
• Operate in wind speed of nominally 15 mph (wind
  speed varies over a 24 hr. period from 0-30 mph
  so need a storage capability)
• Power an emergency communication system with 20W
  at 12V continuous DC
• Able to be carried on a persons back or dropped
  from a helicopter at 20ft without a parachute
