Would those be socks that look like iPods , socks with a pocket to hold your iPod , or socks which contain an iPod with BlueTooth and a play button that triggers when you walk ? I ' d buy the last one . <| sep |> TestEdit hahaha Spez <| sep |> Location location location . You need to live in a geologically active area of the world , or more specifically a volcanically active area . Areas like the east coast of the Americas , Iceland , and New Zealand would all be prime areas for geothermal energy . The problem is all the other areas . If you are in the continental zones geothermal isn ' t much good aside from heating and cooling your home . You can ' t power a nation from an energy source that doesn ' t exist in your area .
