Cell Phone Jammer
God, you people are a bunch of cell phone junkies. Wonder if the radio waves cause a physical addiction, like drugs, after all the brain operates on electrical impulses... Could the cell phone companies be pulling something like the soft drink companies... getting you hooked on their product?
Anyway, its gone around and around about the ethics of jamming. Come on, its a project. It doesn't mean that its actually going to be build, be effective, or even put to use. Cell technology changes almost monthly, how long would it even last anyway.
Finally, so most everyone is against this project... How about a device that rings all the cell phones as the carrier walks through the door. It's short range, doesn't interfere with communications, and merely alerts people that they need to set it to vibrate, if they forgot. Anybody, who refuses ought to be forcebly removed and the offending cell phone smashed to tiny bits....
