Here's Michael Jantzen's experimental design which operates and lives through solar power. This piece of architecture looks very similar to the Fortress of Solitude for some reason.

The environmentally conscious designer has thrilled us every now and then with great designs that could revolutionize the skyline of any place on the planet. Michael’s latest design is known as the Sun Rays Pavilion, which boasts the use of solar panels to power the interiors and also supply surplus electricity to the grid.
