Stingray Wind Energy Systems

How It Works

Screen Shot 2023-02-14 at 11.08_edited.j

Wind Energy (Watts) = 1/2 * Air density * Area * Wind Velocity

Air density = 1.222kg/m

Area of Stingray = 61 square meters

Velocity of wind = 5.5 m/s

​

Wind Energy = 1/2  * 1.222kg/m    *  61m    *  (5.5m/s)    =  6201 W

The average wind speed around the world is 5.5m/s (12.3mph).

When deployed, the sail will experience a force of approximately 900 lb. (408kg) of air per second. This force is transmitted through the six control lines.The control  lines travel down the mast into the base where they are attached to the generators and control motors. 

 

 

 

 

 

 

 

 

 

 

 

 

 

 

The sail travel distance is programmable depending on location but

typical settings will be 60ft. (18.2m) out in 60 seconds.

The retract time is 10 seconds.

​

At the end of its travel,  the sail furls to reduce its area, changes angle and is drawn back toward the mast by the control motors in the base. Just before

the sail reaches the mast, it furls out again to begin

generating power once again.

​

The base swivels naturally depending on wind direction.

​

When there is no wind or when wind speeds are extreme, the sail furls completely resting against the mast until conditions change.

​

An anemometer on the top of the mast provides

both wind speed and direction.

​

The variable nature of the sail's surface as well as six point control allows for precise control and power generation.

​

On-board electronics (grid-tie or stand alone pure sine wave inverter), 

with battery storage can supply both AC and DC electricity.
