The first solar submarine in the world, the Goldfish, was presented a few days ago at the international exposition of Zaragoça. This project only works from sunlight energy.
This submarine gets his energy from five lateral satellites equipped with a total of 300 square meters of solar panels. The energy generated is stored in batteries which after feeds the submarine.
This project belongs to the engineers Martin Pfisterer and Matthuas Zelweger and was developed by the electric company BKW-FMB and the transportation company BLS SA.
This submarine will measure 20 to 30 meters and will hold 20 to 30 passengers. This submarine will be able to submerge up to 200 meters deep and have a consumption of 100 quilowats/hour.
The first dive will be in the first semester of 2011 in the lake Thun, Suisse Alps.
Good luck to this new innovative blend of submarines.
