 Good point, Ed ... eh, Jim!


 Also from the article:

 Reminds me of the MIT students who did a treatise in 2007 on the
 large-scale use of treadmills to harvest sustainable energy :-)


 What obviously should be in focus at this point in time is to
 prevent satellites from crashing into one another. Launching
 a spacecart to obviate an impending crash could well be cost-
 justified.

 Just as tabs is kept on objects approaching the ISS, it's bound
 to be known in several camps long before, if a KH-12 and a KOBALT-M
 are aiming for serious hanky-panky in space. 

 But let's waste neither USD nor EUR on a wild cleaning spree in
 space. If a satellite is coming down, we have corporations such
 as our friends at FEMA to care for us:

 "While it's scary to think of a satellite falling to Earth,
 it's probably less of a danger than a lightning strike or
 other calamity," [Clinton Police Chief Joseph Faughnan] said.
