Swiss Company to Launch Solar Powered Submarine

Andrew Williams — Mon, 24 Nov 2008 12:45:53 +0000

Swiss company BKW has revealed that it plans to launch a 20-30 meter long solar-powered submarine. The vessel, to be used as a tourist attraction, will feature a huge ‘living-room’ style passenger area, as well as 60-70cm viewing portholes.

Under the plan, called Project Goldfish, a team of engineers will build a submarine, capable of carrying 20-30 passengers and two crew, at a depth of up to 300 meters across Lake Thun. Since it operates underwater, the team has figured that it’s pointless to attach solar panels on the sub itself. Instead, the vessel will fully recharge at a floating solar platform on the surface of the lake, decked out with 300m2 of solar collectors capable of supplying up to 30kW of renewable energy.

The decision is a major setback for environmentalists, who had hoped the Court would uphold an earlier injunction by a federal judge requiring the navy to take precautions while undertaking submarine-hunting exercises. Environmental groups originally launched the lawsuit claiming that the use of sonar can injure or even kill a wide range of marine species, including sea-lions and endangered blue whales.
