Do you worry about electromagnetic pollution? Wireless is cool, especially because it works without wires. On the other hand, Wi-Fi, Bluetooth, Zigbee, broadcast radio & TV transmitters, mobile phones and a plethora of electronic gadgets and instruments with base stations on every roof are polluting the electromagnetic environment in which we live. Is this pollution harmful for living organisms or not? Nobody really knows. Does this worry you? Do you wonder how dirty the ether that surrounds you really is? Then the Elektor Tapir is what you need. A tapir is a large browsing mammal, similar in shape to a pig, with a short, prehensile snout.
