depends on if there is onsite security, and whether any particular
tether is especially critical. The falling hardware would be more
hazardous than soft kites falling, and must not drag.
An
onsite PilotInCommand and/or VisualObserver (PIC VO) will help, but
needs a few MW capacity to meet market rates for kWhr.
Anyway,
whoever tries this should be the most careful to identify and resolve
all failure modes.

would consider that a 5 tether system is much safer than any of the
other AWE systems proposed. If one of the tethers are severed,
then the system can be programmed to automatically retract before the
vandal can successfully cut the other four tethers. Perhaps the
blades can be designed so that they slip off the hub if reverse forces
of dragging are imposed on them. |
