Thread Name: BS: Dangers of Electricity Pylons (question)
Subject: RE: BS: Dangers of Electricity Pylons (question)
The choices for society are fairly simple. We have electricity, carried overhead at high tension on pylon lines. It's safe, flexible and cheap but ugly. Or we have electricity, carried below ground at low tension but high current. It's very expensive and inflexible, and it wrecks the archaeology and drainage wherever it goes. You may also have to demolish houses if they are in the way, and the high magnetic fields involved are more likely to have health implications than high voltage, because the high voltage is far away and the high current close by. Or we do not have electricity. Some of you may live remotely enough from civilisation and all it provides to consider this option, but society as a whole does not.
