Passive RFIDs are much cheaper than Active RFIDs, that we all now. I have a problem. The cost of Active RFID for the purpose needed will let my business stay in the ground. Why can't a passive RFID reader's signal be strenghten for the range to be longer. I need 10m range or more. Please explain. Thank you.

Wouldn't that only be possible if there was no resistance? It seems like it would be impossible for a building that size to fall in only 10 seconds. Is that physically possible?

I want some real structural engineers to answer this question. Over 40% of Americans believe that the Twin Towers were brought down by explosives. That's a big number. Are all those Americans nuts? On the morning of 9/11/01 my colleague was on the phone with her husband, a structural engineer. He said that he didn't think the Towers would come down, BUT, he did describe a scenario by which they might come down. He was wrong about them not falling, but was dead on about the manner by which they would fall. Isn't it possible that the fire really did bring down the towers? I'm not ready to accept that my government ACTIVELY murdered 3,000 people that morning (though I've already accepted that they might have done so PASSIVELY).

Just structural engineers. No conspiracy wackos.

If you look at you stapler (as least my swingline has this) you can rotate the plate that bends the staples ends 180 degrees. one way bends them inward (normal) the other bends them outwards.
