Launch a simple rocket on a ballistic trajectory that impacts the item you want to de-orbit. Only aim it to hit the target on the way back down so that the added momentum pushes them into a lower orbit... Another thought would be to use a gravity tractor concept like the one being proposed for moving asteroids. In this instance the goal would be to send a simple thruster device on a path to "not impact" the object you want to move... only use it as a gravity sling which alters the path of both objects in proportion to their mass. If you choose the path correctly, the target heads into the atmosphere and you have the thruster heading for another target. Work it out to do a grand tour style path so you get the most bang for your thruster fuel buck.

There would be very few costs associated with orbital mirrors made of mylar to boost the amount of sunlite in local polar power generation plants. The exhaust would re-condense to complete the cycle. Populate the poles and leave the equator alone.

So can it print the magazine for a mini-gun? No, wait, mini-guns are belt fed.
No sir Inspector Gadget... I do not... and by the way that would not be a bomb threat... it would be a "Hail mary"
“If Edison had a needle to find in a haystack, he would proceed at once with the diligence of the bee to examine straw after straw until he found the object of his search. I was a sorry witness of such doings, knowing that a little theory and calculation would have saved him ninety per cent of his labor.” Nikola Tesla

Please don't mention "The Core"... one of the poster children for bad Sci Fi.
So the AC is all up in my grill about my UID... My handle says all. I started lurking on chips and dips back when many of you were just a gleam in your parents eye. I've paid my dues and my taxes for decades so screw you.
"We the people of the US" funded the inception and development of the Net thru the use of "our" tax dollars which DARPA invested into cutting edge communications research. Here's a quarter ($.25)to go buy a clue. All content is regulated even if you think otherwise. In fact... I'm sure you're doing it yourself at the moment. Self regulation is still regulation!
Perhaps if the files were uploaded to the cloud... Ala Microsoft 7 advertizing... then when the RIAA lawyers kick up the dust and sue, the rain can settle it.
Antilock brakes and traction control have had little effect on the number or severity of accidents since the idiots will just drive to the limit of the equipment. The number of late model SUV's found in ditchs after the first snowfall of the season can provide all the proof necessary.
Cept when you're car won't start cuz the old lead acid battery is too weak to crank and you are trying to call AAA for a jump.
