Unlimited Energy. Think regular flat panels that go on our roofs nested in a scaffold that bolts the panels together and routes the power via conductive channels. The panels are obviously facing inwards towards the centre of the sphere where our sun is located.
The scaffold would be at least 5mm thick, and have some kind of suspension mechanism at every gap or regular intervals. Let's say the average distance between each panel is 20 mm and the panel is a 72 cell system, .99 m $\times$ 1.92 m (obtained via google image search).
If you were to use technology available today, how many of these panels would we need to use?
What other possibly feasible ways could we capture all the sunlight emitted by the Sun?
