eco tourism: solar powered boat
RAboat (lower pic) by Kopf Solar Design in Germany, was assisted by Greenpeace in obtaining the construction materials for a zero emission, solar powered and almost silent boat. It has proved to be quite a tourist attraction for models built in both Germany and the UK. Helio in (the upper picture--also solar powered), has been in operation since 1998 between Germany and Switzerland. It carries 68 people for eight hours at a rate of 15mph--a lovely sight seeing, wildlife friendly mode of transportation. Kopf makes several other models.
