Comparison: conventional drive system vs. Hybrid drive system

A conventional drive system consists of a diesel engine, a transmission and a propeller. The components are coupled together via a shaft. the diesel engine is mechanically controlled by the throttle.
A major disadvantage of the conventional drive system is that the transmission is heavily used which causes early wear.
Additionally, a large amount of space is required for the shaft which connects the diesel engine and the gearbox (transmission) to the propeller. If the shaft rotates throughout the boat' s length, it may also result in increased noise levels.

HYBRID DRIVE SYSTEM
In a hybrid drive system, the "cable replace shaft" concept requires far less space. Energy is stored in a battery bank and supplied via cable to an electric motor. A synchronous (permanent magnet) electric motor is mechanically coupled directly to the ship propeller. These modern, dynamic permanent magnet motors have very high thrust even in the lower speed range. Battery-only operation, already required on many inland waterways and lakes, is now possible.
An efficient diesel generator can also be installed into the system. This is only required to run when the batteries need charging or a higher amount of continuos power is required.
Advantages:
-Space saving
-Low fuel costs
-Low maintenance costs
-On board power supply include
-Very quite system
-Good manoeuvrability

Venezia - Amsterdam: un confronto da fare!

Quest'anno, per la seconda volta, il cantiere navale Gruppo Faldis ha partecipato all'Expo sulle tecnologie elettriche e ibride di propulsione marina, tenutosi ad Amsterdam dal 23 al 25 Giugno. 
Se vivi a Venezia o ne sei un assiduo frequentatore, quando arrivi ad Amsterdam è impossibile non guardarti intorno e fare un confronto tra le due città. Infatti, escludendo la possibilità del passaggio di bici e macchine nelle strade della capitale olandese, le due città possono essere equiparate per gli incroci di canali e corsi d'acqua navigabili che le attraversano. 
Una grande differenza tuttavia salta all'occhio immediatamente: la navigazione è completamente differente. Imbarcazioni di tutte le dimensioni, dalla barchetta a pedali alla barca da turismo, solcano le acque dei canali in modo agile e silenzioso.
Vi lasciamo con l'articolo che ha ispirato questo post: un giornalista olandese in vacanza a Venezia racconta le sue interessanti osservazioni sulla città. 
Venezia può e deve cambiare... Deve essere un turista a farcelo notare?

"A long weekend in Venice got me thinking about the impact that new-generation marine propulsion technology is having on waterways, canals and coastal regions around the world. Or not, in Venice's case. 
Steeped in history with iconic landmarks around every corner, Venice's only means of transport is through its latticework of waterways. And here diesel-engined boats are king, beaten in numbers only by the man-powered gondolas.
From the airport, one is transferred to the main island in a rickety, chugging 80-seater sea hopper that's seemingly been designed with passenger comfort last in mind. In fact, the journey was about as uncomfortable and rudimentary as Venice is relaxed and beautiful. The water taxis that connect the islands are just as basic, buzzing, smoking away, getting Venetians and tourists from A to B. 
Don't get me wrong, I am a big, big fun of the diesel and Jean, regardless of industry or application, but if ever there was a case for eco-friendly, next-generation silent-running hybrid and electric marine propulsion, Venice is it. Having a macchiato, with the Italian sun beaming down from on high, would be so much better along a quieter thoroughfare without the sound of a rumbling diesel motor, or the smell of spent fuel. That day will come for Venice, for sure. In fact legislation is already making sure such a dream will become a reality; it's just a shame that it didn't happen before my weekend away.
Those in charge of Venice's transportation system should definitely take a trip to Amsterdam - a city that's not only embracing new-gen propulsion solutions to clean up it's canals and waterways - but also the place where the second Electric & Hybrid Marine Technology Expo will take place. Across June 24, 25 and 26 at the Amsterdam Rai, leading developers and innovators will be showcasing new technologies, designs and concepts that will reshape cities like Venice. I wonder if the coffee will be as good."
