Galveston Island is a barrier island located two miles off the Texas coast. The island is about 3 miles wide at its widest and about 28 miles long. The Galveston Seawall extends over 10 miles along Galveston's oceanfront, protecting life and property against hurricanes and tropical storms.

This fusion-welded drum, tested during 1930, was the first in a series tested at Combustion Engineering Inc. that led to the industrial acceptance of welding for the fabrication of boiler drums. Replacing riveting for steam power plants, electric arc fusion welding permitted increased efficiencies through higher working pressures and temperatures and fabrication of larger units of improved safety. Welding was then rapidly extended to fabrication using optimum alloys for pressure vessel and structural application.

In early September 1985, a team of scientists discovered a previously unknown pure carbon molecule, C60, which they dubbed buckminsterfullerene. The name was chosen because the geodesic domes of Buckminster Fuller provided a clue that the molecule’s atoms might be arranged in the form of a hollow cage. The structure, a truncated icosahedron with 32 faces, 12 pentagonal and 20 hexagonal, has the shape of a soccer ball.

In 1907, John Fritz, known as the "Father of the Steel Industry in the United States," rejoined the Lehigh University Board of Trustees after an absence of a decade. He began the development of what would prove to be his greatest gift to Lehigh: a modern engineering laboratory and funding for its construction.

The Fresno scraper established the basis for the modern earthmoving scraper, being able to scrape and move a load of soil, then discharge it at a controlled depth. It quadrupled the productivity of manual labor, replacing hand shoveling of earth into horse carts.

The Fort Peck Dam was a cornerstone project of the Works Progress Administration of Franklin D. Roosevelt's New Deal. It required the largest construction plant and workforce since the construction of the Panama Canal and peaked at 11,000 workers. It was the largest dam of any type in the world for over 30 years.

The historic Folsom Power House #1 marks one of the first successful uses of hydroelectric power in the world and the first successful transmission of power long distance (twenty-two miles to Sacramento). The old Folsom Power House still shelters the machinery generated to drive streetcars and illuminate the city of Sacramento.

"The State [of California] agreed to construct the dam using convict labor for which consideration the State received a grant of land for the construction of a prison and water power rights from the impounded water ...; The work progressed slowly during the dry season by disinterested convict labor using hand tools since the use of machinery was forbidden ...;"

Squeezing an orange for juice is part of the concept of this machine, only on a much larger scale. The extractor revolutionized the juice industry. The twenty-four head rotary action simultaneously extracts juice from the interior of the fruit and citrus oil from the peel surface. The first unit was operated experimentally on grapefruit at the Sunkist Exchange plant in Tempe, Arizona, during late May of 1946. Tests on citrus fruits continued in California, Texas, and Florida.
