Retro Solar Panels

This funky array might look more like elaborate hair curlers than solar panels, but in the 1970s it was the latest in solar design. Created for the Argonne National Laboratory in Lemont, IL, these “solar concentrators” were designed to generate electricity for heating and cooling systems at the lab. Solar technology and green building techniques have come a long way since then, but it’s hard to deny how groovy this looks.
