And what country can preserve its liberties if their rulers are not warned from time to time that their people preserve the spirit of resistance? Let them take arms. The remedy is to set them right as to facts, pardon and pacify them. What signify a few lives lost in a century or two? The tree of liberty must be refreshed from time to time with the blood of patriots and tyrants.

Lawrence Livermore National Laboratory world’s heaviest door
The heaviest door in the world, according to Guinness World Records, is the radiation shield door at the National Institute for Fusion Science in Toki, Gifu, Japan. This massive door weighs 720 tonnes (approximately 1,587,328 pounds), measures 11.73 meters (38 feet 6 inches) in height, 11.4 meters (37 feet 5 inches) in width, and is 2 meters (6 feet 7 inches) thick. It was installed in December 1994 by Itoki Co. Ltd. and is designed to protect the outside world from the intense radiation generated within the fusion research facility. While other large doors exist, such as a 97,000-pound (44-tonne) hinged door at Lawrence Livermore National Laboratory in the United States, which was once considered the heaviest, the Japanese door holds the official record.
At first glance, I was going to say that the blast doors at the NORAD facility on Chyanne Mountain in Colorado Springs might be heavier, but the Japanese Fusion Science building takes the cake.
That's not Lawrence Livermore, that's ENCOM!
ReplyDeleteNow that's a big door!

That is a door serious about keeping something either in or out...

ReplyDeleteI wonder if it has a Ring Camera doorbell.
ReplyDeleteIs that to keep the 'bottled sunshine' in or out ... asking for a friend...
ReplyDeleteWhy have such a door?
ReplyDeleteTo keep the Japanese citizens living nearby from being nuked if an accident might occur. Unlike the Russian, nuke disaster in Chernobyl.
DeleteActually, the heaviest door is my bedroom door when I come home from drinking with the guys.
