"Big Delta is a massive delta 3D printer developed by WASP, the World&amp;#039;s Advanced Saving Project.  This 3D-printer is 12 meters high and is designed to build hugely inexpensive, nearly zero-cost housing using easily available locally sourced materials. What&amp;#039;s great about this massive 3D printer is that it is also intended to function using as little energy as possible, meaning it won&amp;#039;t be too expensive to run. The advantage of Big Delta is that it will be able to offer rapid and surprisingly inexpensive relief in disaster areas. Moreover, it will be able to address housing needs in the future, in a world where the population is growing exponentially and the cost of living is rising at a frightening rate."^^<http://www.w3.org/2001/XMLSchema#string>
