DESCRIPTION:The Stratospheric Particle Injection for Climate Engineering (
 SPICE) project investigates the benefits\, risks\, costs and feasibility o
 f solar radiation management through the deployment of reflective aerosols
  in the stratosphere. The proposed delivery system for this project is a n
 umber of tethered balloons reaching from sea level to an altitude of 20km.
  By means of an ultra-high pressure pumping system\, the particulate slurr
 y is pumped through the tethers and dispersed at altitude. The economic fe
 asibility of such a system depends upon the long-term deployment of the ba
 lloon and sufficient pumping capacity to deliver an estimated 10 million t
 onnes per year of aerosol.\n\nThere are many novel engineering challenges 
 that are involved in the design\, manufacture and operation of such a syst
 em. This presentation discusses a number of these challenges\, and present
 s a preliminary design consderations for a 1km test-bed that is due to be 
 constructed in November this year. Preliminary wind tunnel test results ar
 e also presented\, to illustrate the complexity of the dynamic behaviour o
 f the tethered balloon system.\n
