Welding welding was invented in 1893, and around that time another process, oxyfuel welding, became well established. Acetylene was discovered in 1836 by Edmund Davy, but its use was not practical in welding until about 1900, when a suitable torch was developed. At first, oxyfuel welding was one of the more popular welding methods due to its portability and relatively low cost. As the 20th century progressed, however, it fell out of favor for industrial applications. It was largely replaced with arc welding, as advances in metal coverings (known as flux) were made. Flux covering the electrode primarily shields the base
British Rail flying saucer many of the technologies used in the craft, such as nuclear fusion and high temperature superconductors, had not yet been discovered, while Colin Pillinger, the scientist in charge of the Beagle 2 probe, was quoted as saying "If I hadn't seen the documents I wouldn't have believed it". British Rail flying saucer The British Rail flying saucer, officially known simply as "space vehicle", was a proposed spacecraft designed by Charles Osmond Frederick. The flying saucer originally started as a proposal for a lifting platform. However, the project was revised and edited, and by the time the patent was filed had
