UltraTech LEEC species

So it is a partial dyson, rather than a full dyson. This would also work, but of course the amount of usable energy is reduced.

As mentioned upthread, it is a Dyson Bubble, made of orbiting statites, not a Dyson Shell. The Tleitylwesi Bubble covers just a shade over 90% of the sphere surrounding their system's stars (a close binary system); since it was constructed primarily to provide concealment, the power generated by its 21.3 quadrillion statites (actually, the Bubble generates only a small percentage of their total power generation) is a bonus. Additionally, the Bubble described is only one of 87 such structures built and maintained by their civilization.
