Swedish firm designs solar-powered submarine

Sweden's BKW FMB Energie is trying to secure investors for its solar-powered submarine that can use existing technology to recharge at solar-panel platforms.

'Projekt Goldfisch' is designed to transport up to 24 people to a maximum depth of 300 meters. BKW said it wants investors willing to contribute 10 million Swiss francs ($8.4 million USD).

BKW said it's one of the largest energy developers in Sweden, with other unusual solar projects under its belt, including the world's largest solar ship in 2001 and the world's highest solar power station. 

BKW said the submarine could be built using existing technology in the submarine and solar sectors. Potential uses include tourism in China or Dubai, the company said.

In its pitch for investors, BKW describes the uses: "A solar powered shuttle boat brings passengers from a starting point on shore to the floating solar platform, from where the submarine's trips into a fascinating underwater world begin." 

BKW said it completed a feasibility study in June for the project. The solar plaform could also be used to power buildings on the lake shore, BKW said.

"Like a water lily, the floating solar platform consists of a central element with a marquee, surrounded by five satellites fitted with solar panels," the company said on its Web site.
