Hey, the sun is free, why waste it? Heliostats, or mirrors that track the sun, are being installed around the world to send sunlight in places where it doesn't shine. Shown above are on top of a residential building in Battery Park City, New York, shining into Teardrop Park.

Also a good article on passive design: "Although basic, time-honored design strategies such as exterior shading, interior thermal mass, operable windows, and careful site orientation have reemerged in the past decade under the guise of green architecture, passive or natural ventilation remain exceptions."
