Initial SE Contest at NASA Ames in Oct 2005
Beam Power Challenge: designed by NASA‘s Centennial Challenges program to promote development of new
SE related power distribution technologies. 7 university teams competed, first technology demonstration. No winner in 2005
Tether Challenge: foster the development of super strong space tether material. The competition
requires a 50% improvement in breaking force from year to year

Beam Power (Climber) Challenge in 2006
Courtesy: Spaceward Foundation
Climber competition entries are rated according to the product of payload weight and climbing speed, normalized by the net climber weight. 2006 target is to have loads (climber + payload)of about 50 kg move up a ribbon at a speed of 1 m/s for about 1 minute, corresponding to 500 watts of mechanical power.
v=1m/s
m=50 kg
