Orbital product logic
Three scales. One orbital language.
The three series move outward from everyday residential use to commercial energy coordination and utility-scale infrastructure.
Focal · Centre
The focus of an ellipse represents where commercial and industrial energy is gathered, scheduled and controlled.
Aphelion · Far
The farthest point in the orbit represents larger-scale, more distributed energy infrastructure.
