update Calagator::Event 1250458145 Launch Loop - PSU Physics Seminar Roll back

description The Launch Loop can launch thousands of tons per day to high orbit for dollars per kilogram. It stores momentum and energy in a long (5600km) and narrow (5 cm) hypervelocity (14km/s) iron rotor. The Launch Loop is electrically powered and deployed from the ground, protected from space debris by the upper atmosphere, and can be built with existing engineering materials for a few gigadollars. Near term spinoffs will include power storage and transmission, permitting global peak usage leveling. → The Launch Loop can launch thousands of tons per day to high orbit for dollars per kilogram.
