Topographical sat nav

About 15% of the causes of global warming come from transportation. A major portion of that comes down to trucks on our roads – which play a major role in keeping our economy going.

Therefore anyone with an interest in reducing carbon emissions must applaud any efforts to increase truck fuel efficiency. This webpage contains a host of advice for truck drivers along those lines. One interesting new development is topographical sat nav:

Topographical (TOPO) satellite navigation systems will not only inform you of road markings, but also elevation in the geography, which can help you plan ahead more efficiently. For example, a peak in elevation could prompt you to increase the throttle and gain more momentum. In addition – like most GPS devices – they are able to calculate the most efficient route for your journey. If the purpose of your newfound interest in fuel economy is environmental, there are also solar powered options available.
