The sleek exterior design already hints at the vessel's high-tech interior. Sailing yacht Ecolution, the work of former astronaut Wubbo Ockels, generates its own electricity and is constructed from sustainable materials. If Mr Ockels has his way, it will be the yacht of the future.

The secret of the 25-metre two-master lies under the waves. There the Ecolution conceals two vast carbon propellers that generate power while she sails. The resulting electricity is stored in two batteries which also provide the necessary ballast. Five days of sailing produces sufficient energy for a whole month's creature comforts on board.

Fully fitted
On board there are four toilets, underfloor heating, a fully fitted kitchen including a microwave, a dishwasher and an oven, and even a shower and steam cabin. The vessel can sail into port using electric motors. In an emergency, the crew can resort to biodiesel. For this purpose, the ship has two separate engine rooms.

The Ecolution will experience its baptism of fire this week at Sail Amsterdam, where it will be given pride of place in the parade of tall ships bound for Amsterdam. During Sail 2010, the Ecolution will be open to the public and this coming winter it will be on display in Scheveningen harbour near The Hague.

One planet
Wubbo Ockels, who became the first Dutchman in space 25 years ago, has since made a name for himself as an advocate of sustainable solutions. His message is simple: we only have one planet, so we have to handle it with care. Mr Ockels' has previously championed a solar-powered car and a super bus that can reach speeds of up to 250 kilometres an hour.

The former astronaut is determined to test his latest invention in person, with the eventual aim of building more. The price of these special yachts is expected to be around four million euros. Given the price tag, it comes as scant consolation that there are no additional crew expenses. It only takes one or two people to man the Ecolution.
