With a name like Big Pit: National Coal Mining Museum -- located in Blaenafon, Torfaen, South Wales -- you would think the place would keep with the theme by powering their museum with the very same stuff they tore apart the land to get. In an ironic twist, the museum has installed 200 solar panels atop the building's roof, providing them with a constant energy source that produces no harmful emissions. In truth, this is merely a nice little perk in comparison to what they really gain from their decision to go eco-friendly. In fact, one can say the museum is making the green by going green.
A new study has found the exact origin for some of Stonehenge's oldest stones. The rocks, which may have been part of the inner ring and "horseshoe" portion of the ancient landmark, are now confirmed to have come from an outcropping of rocks in Wales called Craig Rhos-y-Felin in north Pembrokeshire -- some 160 miles from Stonehenge. While the research is a worthy discovery in its own right,it could give some clues about how the massive stone circle was constructed.
