Second, the big screen TVs spend much more time watching cable or DBS than OTA.And third, the RF energy density impinging on humans using these handheld two-way devices far exceeds the energy density created by the broadcast stations. So by anything resembling logic, the proliferation of ever broad-er-band RF handheld devices can hardly be considered "green."
Once again wrong.The RF energy density is far more uniform and at lower power levels that the big sticks. You must look at the energy density of a big stick based on distance from that stick. If you are "lucky" enough to live near one of these RF "heaters" the energy density where you live will FAR EXCEED the density of todays low powered cellular and other wireless networks.
But none of this approaches the energy density caused by the sun. Regards Craig ---------------------------------------------------------------------- You can UNSUBSCRIBE from the OpenDTV list in two ways:- Using the UNSUBSCRIBE command in your user configuration settings at FreeLists.org
