The past tense for "wind" is "wound" and for "sweep" is "swept."

An erg is a broad, flat area of desert covered with wind-swept sand with little or no vegetative cover.
When looking at what a phrase means, break apart the phrase. Swept means cleaned, or it can mean an act that was 'sweeping', like wind blowing dust (which can create debris rather than 'cleaning') Area is a defined space, of any size or shape. In the phrase "swept area", we do not need to know the size or shape of the area. The phrasing implies either a known area, or an unknown expansive area. Example: The manager inspected the swept area in the shop for thoroughness. (The employees and manager know the size of the area.) The windswept area became littered with leaves and paper trash.

winded swept
An erg is a large, flat area of desert covered with wind-swept sand a little or no vegetation. It is a landform common in the Sahara desert.
Patagonia is wind swept plateaus and the Pampas are plains.
There is a good introductory article on wind power in Home Power magazine issue 127 (October/November 2008) titled "Wind Power Curves". The quick summary is that the theoretical limit for energy capture (the Betz limit) is 59.6% of the energy in the wind. The wind energy available depends on the wind speed. If the average wind speed is known, the available energy can be calculated assuming some standard distribution (normally Rayleigh distribution) of wind speeds. Some sample figures (based on Rayleigh wind distribution and 35% turbine efficiency): 5mph average -> 0.25 kWh/month/sq.ft 10mph average -> 2.08 kWh/month/sq.ft The power figure is per square foot of swept area (the area covered by the turbine blades when rotating), so if you have 100 sq. feet swept area then 10mph average wind speed could generate 208kWh/month.
Gone with the Wind.
Extra debris was swept out away from our solar system by the sun's radiation and solar wind towards the end of the formation of our solar system.
