About Not Using Winches, Reels, Drums, Trucks, or Platforms for Main Tethers’ Anchor Assemblies

Some AWES may benefit from having main tethers immediately anchored to Earth without involving winches, reels, drums in anchor assemblies. Exploring this realm is the topic. Of course, the AWES that essentially need winch-generators, reeling for yo-yo, mobile trucks, and the like, are not involved in this topic. I suggested the absenting of such items in versions of the AWES being discussed in the "Edit#01 HERE.

A scenario might go like this: Lay in the flight field a 600-meter main tether; connect the line to Earth immediately; connect the far-field of the main tether to the AWE wing-set bridling. Connect other parts of the AWES. Launch the wing set by various methods. Harvest energy from the wind and use that energy for producing electricity or other works. The cost of a main winch, reel, drum, etc. is not then present.

Of course, such direct anchoring sans winch is not a new concept. But deliberately so doing for huge AWES may be explored for possible advantages in some AWES. The method may be the way to go when ultra-large wings are involved. Indeed, reeling costs, winch costs go up significantly for large AWES. Tease: https://www.shutterstock.com/search/mooring+winch

Notice, that non-FFAWE or powered aircraft RAT systems, AWES connect to Earth anyway. Consider this topic, then.

PS: Safety !!! No matter how wings are opposed, safety is paramount.

Re: Anchors as wings in kite systems

The "anchor wing" or "anchor wing set" may have media of air, water, air and water, soil, plasma, soups, blood, solar wind, magnetic field, etc.  The wing set being anchored by the "anchor wing set may be doing good works and may be part of the PTO operations.  Likewise, the anchor-wing set may be doing good works and may be part of PTO opeerations.   We may look at some toy or recreation examples before reaching for the starts.

Conside a toy-kite system with the following field design: At far downwind of the filed is a catch fence designed to catch and stop the progress of a kite system at play. Upwind are folks with kite systems that feature anchor wings that have sand and air as the flow media that will be deflected by the anchor wings.   The upper-air wing set of the kite systems drag the lower anchor wings through the sand. The pilots have remote control over surfaces of the anchor wing.  As the anchor wings are pulled by the systems' tether set, the pilots control the surfaces of the anchor wings. The pilots are tasked with making design in the sand using the anchor wings as the groovers.  Finally, the downwind fence catches the anchor wings and the motion of the kite systems stop.

Consider industry fishing or scientific sensing on ocean bodies. The boat is the powered wing; the spreader paravanes (water kites) are wings in a water media. The trailing wings are anchoring the boat. The good purpose of the spreader wings are to spread nets or position sensing devices over an area.

Safety:  Be ready for what may happen to any kite-system anchor set. The anchor set is a wing set and may fly in unwanted ways forming a costly incident. The anciently known breakaway kite might occur from line breaks or an unwanted movement of the anchor set.  If an anchor is a steel spike, then a pulled-out spke flying through the air could cost lives and property damage.  Even a loose long tether in a breakaway incident still anchors some the upper wing set of a kite system; such flying loose tether or tether set  then flies to places that could cause large damage to properties and lives.

Notice when the anchor is moving by the pull of a larger kited wing.
