Yes but considerable thuster energy and ejection mass are needed to aim the cylinder toward the sun, due to the million plus tons of mass in the cylinder. On third thought, the twin cylinder idea likely is not good engineering, as the first ten may not work and it will be very difficult to repair when it malfunctions. We needed the trusters to get the rotation up to speed, they can make the adjustments in the atitude, and they can dampen any wobble and vibration that arises. Lots of independent thrusters means good redundency and indivial thrusters are easier to repair. Worse the twin cylinder system will slow the rotation each time it changes the attitude. We should not suppose it is a free energy devise. The many moving mirrors may also be unreliable. Two spheres rotating each other, with a kilometer of tether, may prove most reliable, most versitile and least costly, per habitat dweller, partly because a sphere is stronger than other shapes. Admittedly docking at either sphere is chalanging. Thousands of individuasl window panes may also be bad for reliability and low air leakage. The thick walls required even if they are made of diamond may be show stopper as the stress with rapid temperature change can be enourmous.
