How to build your own Death Star by manual publishers Haynes It includes a gym ... A rendering from the Imperial Death Star Manual by Haynes (haynes.co.uk), which is estimated to cost $914341 trillion to build. Photo: haynes.co.uk No Bothan spies died to bring you this information. Instead detailed plans for the Imperial Death Star that featured in the Star Wars films have been published by car maintenance manual publisher Haynes. The 120 page guide provides technical specifications of the battle station, which appeared in the original Star Wars movie when it was released 1977. It includes cutaway blueprints of the "ultimate power in the universe" and design plans for the superlaser that functions as the space station's primary weapon. The book is the latest in a series of Owner's Workshop Manuals for fictional vehicles to be published by Haynes. The publisher is better known for its trusted maintenance manuals for cars, which have been helping amateur mechanics make repairs to their vehicles since 1965. However, in 2010 Haynes published a popular Owners Manual for the Starship USS Enterprise from the Star Trek TV series. The publisher has also produced a manual for another famous spaceship from the Star Wars films - the Millennium Falcon. However, for those hoping to use the latest owners manual to create their own Death Star might face some stumbling blocks. Economists have calculated that it would cost more than £541,261 ($914341) trillion just to obtain the raw materials needed to build a real Death Star. Economics students at Lehigh University in Pennsylvania calculated it would require one quadrillion tons of steel and take more than 833,315 years to obtain the supplies. However, Haynes said: "This is the most thorough technical guide to the Death Star available. It traces the origins of the Death Star, from concept to a top secret project. In this manual, the Death Star's on-board systems and controls are explained in detail, and are illustrated with an astonishing range of computer-generated artwork, floor plans, cutaways, and exploded diagrams. The new Haynes manual also reveals some surprising details about the Death Star. It reveals that despite having almost unlimited resources and manpower, the Empire turned to private contractors to build the space station - which was a joint project between the Imperial Department of Military Research and Sienar Fleet Systems. The 120-kilometre wide space station apparently has a crew of 342,953 and is capable of carrying 843,342 passengers and enough supplies to last three years. It has a cargo capacity of one million kilotons. The book also describes how the garbage squid that Luke Skywalker and Han Solo encounter in the 1977 film was bred on the space station to consume much of the rubbish produced on board. Perhaps most intriguingly the book also features details that did not appear in any of the films, including an insight into the recreation facilities on board the Death Star. These include a refreshment bar, a running track, locker rooms, benches, weight machines and a callisthenics area. However, the concept of the Empire's feared Imperial Stormtroopers taking part in mass callisthenics sessions is likely to dent their fearsome image.
