Magnetic Propulsion Union
This content is for the 1.0 version.
Magnetic Propulsion Union (MPU) was founded by three professors at Princeton who continued work with mass drivers originally started by Gerard O’Neill. The MPU has spiraled out into a large international project, encompassing many universities and voluntary projects. They exist as a large repository of knowledge and idealism; with constantly improving designs, in terms of launch mass, efficiency or reliability.
MPU offer to build mass drivers with a muzzle momentum of up 120,000 kgms-1. The price of such a system is based on the length of the mass driver, costing $50,000,000 per kilometer, and massing in at 98,000,000 kg per kilometre. The mass driver will impart 6000 kgms-1 per kilometre of length. Shipping is not included. The mass driver transfers energy to projectiles with a 60% efficiency.
