Can an ar­ti­fi­cial hip help power a jet plane?

World of Knowledge (Australia) - - Question & Answers -

It’s a tan­ta­lis­ing thought. The ar­ti­fi­cial hip that could help us to walk in later life might one day power some­thing a good deal faster than a hu­man be­ing. The re­cy­cling of pros­thet­ics such as ti­ta­nium hip re­place­ments and cobalt chrome knee joints from cre­ma­to­ri­ums is a grow­ing trend across Europe. Orthomet­als, the com­pany be­hind the re­cy­cling, says over half of Bri­tain’s 272 cre­ma­to­ri­ums have signed up to the scheme, which last year helped re­cy­cle 450,000kg of metal. The metal is first sorted, then sold on to a foundry. Some of the higher value me­tals are then sold on again to cast­ing com­pa­nies to be made into com­po­nent parts for the aero­space in­dus­tries, such as air­craft tur­bine blades and en­gines. Even cheaper me­tals like steel (used in the plates that hold legs and skulls to­gether) are smelted down and reused in road signs and lamp posts.
