> "Furthermore, any scientist will tell you a non-powered set of unenergized coils cannot amplify anything. Amplification requires power. Bedsprings are not powered." You might wonder how a magnifying glass can ignite paper, why a satellite dish on the side of a house is a dish, how a solar cooker works, why a radio telescope works, or how a roof can turn trickles of rain water into a powerful stream coming out of a drain, all of them unpowered, all of them not needing powered amplifying to have an effect. |
