Manuel Salinas, a 39-year-old inventor, claims he has built a machine that has extraordinary capabilities for finding buried objects. And now that university lab tests seem to confirm that his robot works, mining and oil corporations are flooding him with business plans. How this machine functions is still an industrial secret," Salinas said. But ask him for proof that it works and he'll hand you a pile of press clippings on the device, called Geo-Radar or Arturito (a play on the name of Star Wars robot R2-D2). In September 2005 Salinas announced that he had found gold and buried treasure on the Juan Fernndez Islands...off the coast of Chile. Recently, Salinas asked a Chilean university to study the machine and put the questions surrounding it to rest. In early May the results came in, and the Geo-Radar jumped back into local headlines. University investigators announced laboratory and field tests indicating that the Geo-Radar technology is capable of quickly finding copper deposits, petroleum, and gold bullion at depths of up to 600 feet (283 meters). "This reduces the time of exploration from three months to one day," said engineering professor Ricardo Neira Navarro at a press conference in Santiago, the national capital. "I built this machine to find buried antipersonnel mines," explained Salinas. When he finished building the machine in 2004 and ran field tests, Salinas says, the machine surprised him with its abilities to find water, petroleum, and buried metals.
