Railways

A major advantage of using the TDWG with train traffic is the potential to capture energy from three sides, whereas the need to change a flat tire and have a safety lane on normal roads precludes anything but an upper mounting. A second advantage is the closer proximity of the train body to the rotor vanes, which allows more energy capture, since trains pass very closely to tunnel walls, poles, etc. Electric trains can efficiently derive some of their operating power directly from the TDWGs, rather than from utility plants burning hydrocarbons and sited at great distances.
