This is a list of the world's largest machines, both static and movable in history. Building structure ... Tunnel boring machine: 99 m (324 ft 10 in) [8] 17.5 m (57 ...
The largest air-insulated Van de Graaff generator in the world, built by Dr. Van de Graaff in the 1930s, is now displayed permanently at Boston's Museum of Science. With two conjoined 4.5 m (15 ft) aluminium spheres standing on columns 22 ft (6.7 m) tall, this generator can often obtain 2 MV (2 million volts).
Electrostatic machines are typically used in science classrooms to safely demonstrate electrical forces and high voltage phenomena. The elevated potential differences achieved have been also used for a variety of practical applications, such as operating X-ray tubes, particle accelerators, spectroscopy, medical applications, sterilization of food, and nuclear physics experiments.
It was named after James W. Bagley, a USGS topographic engineer who developed the Bagley T-3 camera and mapped Alaska prior to World War I. [1] At 200 km (127 mi) long, 10 km (6 mi) wide, and up to 1 km (3,000 ft) thick, it covers most of the core of the Saint Elias Mountains and part of the Chugach Mountains . [ 2 ]
Bagger 288 (Excavator 288), previously known as the MAN TAKRAF RB288 [2] built by the German company Krupp for the energy and mining firm Rheinbraun, is a bucket-wheel excavator or mobile strip mining machine. When its construction was completed in 1978, Bagger 288 superseded Big Muskie as the heaviest land vehicle in the world, at 13,500 tons. [3]
Alaska Native Science and Engineering Program. The following list of Alaska Native inventors and scientists begins to document Alaska Natives with deep historical and ecological knowledge about system-wide health, knowledge that in many cases precedes and exceeds discoveries published in the scientific literature.

Then, they found a new volcano-like formation deep in the ocean waters. The new volcano-like structure sits more than 1,600 meters from the water's surface. So, it's far too deep to pose a danger ...
