ARodriguez well (orRodwell) is a type of well envisioned by Swiss glaciologist Henri Bader of Rutgers University and developed by engineer Raul Rodriguez of the United States Army for economical harvesting of drinking water in polar areas. The project began as a subproject of the Army's Camp Century base in Greenland, created as a demonstration for affordable ice-cap military outposts or bases for scientific research.[1][2]
U.S. Army engineer Raúl Rodríguez-Torrent (1921-1985) was born in San Juan, Puerto Rico to Eugenio Rodríguez-Suárez and Genara Torrent y Becerra de Rodríguez. When Raúl Rodríguez Torrent was born about 1921, his father, Eugenio, was 34 and his mother, Genara, was 33. In 1940, he was 18 years old and lived in Rio Piedras, Puerto Rico, with his father, mother, 3 brothers, and 2 sisters. In 1940 he enlisted in the U.S. Army and later became an engineer at the United States Army Corps of Engineers (USACE). [citation needed]
Developed at Camp Century in Greenland during the early 1960s, a Rodriguez Well (Rodwell), uses heat exchangers and a submersible pump to create a cavity deep under a glacier’s surface and cycle the heated water up an ice shaft, siphoning a portion of the flow for consumption before sending the rest back down to the well. Camp Century was a preliminary camp for Project Iceworm whose end goal was to install a vast network of nuclear missile launch sites that could survive a first strike. If this model were found to be effective, an efficient means of supplying water to staff stationed on site needed to be developed. Project Iceworm was a top secret United States Army program of the Cold War, which aimed to build a network of mobile nuclear missile launch sites under the Greenland ice sheet. The ultimate objective of placing medium-range missiles under the ice — close enough to strike targets within the Soviet Union — was kept secret from the Government of Denmark.
Heated water is used to melt a shaft over a hundred feet deep, eventually forming a cavity beneath the surface at the point where the shaft ends. By continuously replenishing this pool of heated water, the deep pocket of melted water gradually expands, renewing the supply of fresh water available to be pumped to the surface.[1] The process was inspired by the observation that room temperature sewage injected into the arctic surface eventually formed a pocket around 100 feet down which would not refreeze as long as more sewage was continuously injected.[1] The lifespan of a Rodriguez well is over seven years, ending when the depth of the cavity becomes too deep for the facility to efficiently heat and recirculate water.[3]
A Rodriguez well was driven at the National Science Foundation's Amundsen–Scott South Pole Station.[3]
NASA is presently working with the Cold Regions Research and Engineering Laboratory of the US Army Corps of Engineers to design a proof of concept of a Rodriguez well usable in polar regions of Mars.[4]
We create a Rod well, which is a cavity deep in the ice where we melt ice to create our own drinking water
NASA reached out to CRREL experts and requested the laboratory's involvement in adapting their Rodriquez well simulation model to help design a Rodwell for Mars
