[Worldkings] Top 100 innovation events in the world (P. 41) The Candela company makes a big splash for its zero-emission "flying" boat on water surface (Sweden)

(Worldkings.org) Appearing at a glance to be just a simple pleasure boat floating on the San Francisco Bay, as the hydrofoil-equipped vessel picks up speed it suddenly begins rising above the water, grabbing the attention of passengers on a nearby ferry. But instead of a roaring engine thrusting the boat along, its electric motor barely makes a sound.

Candela touts the C8 as the "fastest" and "longest-range" electric boat on the market, traveling as far as 57 nautical miles (about 100 kilometers) on a single charge with an average speed of 22 knots and peak at 30 knots. Candela seeks to differentiate itself with hydrofoils and an advanced computer that automatically adjusts them to keep voyages smooth and safe.

 

Such electric boats with computer-guided hydrofoils may soon supplant conventional ferries with combustion engines in harbors and bays around the world, if Swedish "flying boat" maker Candela has its way.

"It's half plane and half boat; almost like riding a magic carpet," French sailor Tanguy de Lamotte said from the helm of the 8.5-meter (28-foot) long C8.

De Lamotte, who has completed the Vendee Globe solo round-the-world race in a sailboat twice as large as the C8, heads Candela's US arm. The Swedish company's goal is to make the most energy-efficient electric boats "and get away from fossil fuels," according to de Lamotte.

Hydrofoils that act as underwater wings lift the boat as it accelerates, leaving only the rotor and hydrofoils immersed and greatly reducing friction. In addition to using some 80 percent less energy to travel, the boat also avoids nausea-causing waves or swells, de Lamotte said. And since the engine is electric, passengers are spared the noise and smell of gas-powered motors.

 

Candela has received some 150 orders for the C8, which has a starting price of $400,000. The first delivery is expected to arrive in Florida by the end of the month. While the project may seem like a drop in the ocean when it comes to countering climate change-inducing fossil fuel emissions, it is at least an oar stroke in the right direction, Lamotte contended.

Even if the C8 is a hit, their environmental benefit would be limited since recreational boats tend to be used only a couple of days a week and when weather is pleasant.

So Candela wants to tackle ferries. Their next model is a catamaran with 25 seats to be tested as a shuttle in the Stockholm archipelago later this year, he said. The service is expected to cut in half the amount of time it takes people using ferries or buses to get from the Ekero suburb to the city center once it gets going.
