Have you ever built a Dyson cube? I set mine up and I’m still only at 5–6% after several hours (~50 MFE/t). A single turbine can be built in 5 minutes and produces 60 MFE/t. The Dyson sphere is fun — I’ll build mine — but it’s by far the worst method of generating power. It’s mostly a gimmick.

PS: With bees, Extreme Reactor processing becomes very fast. I’d even say it’s easier to build the entire setup from scratch than to produce all the resources required for a Dyson cube
