Siemens Builds World’s Largest Offshore Wind Turbines And DONG Will Operate The Wind Farm.

World's Largest Wind Turbine - SiemensSiemens is building the massive 6-megawatt wind turbines and DONG Energy will manage the project off the Yorkshire coast. DONG’s long term plan is to install 300 of the Siemen’s wind turbines around the UK. It’s great to see DONG and Siemens working so well together. [e360]


ZeroCat™: Electric Car-Carrying Ferry.

Electric car-carrying ferry from Siemens and Fjellstrand for NorledIn 2015, the Norwegian villages of Lavik and Oppedal are going to be linked by the world’s first electric car-carrying ferry. The ZeroCat™ electric ferry, which is being developed by Siemens and Norwegian shipyard Fjellstrand for Norled, will replace the current car ferry that uses approx 264,000 gallons of diesel fuel each year. From Gizmag:

“The 80-meter (262.5-foot) catamaran can carry 120 cars and 360 passengers across the fjord between the villages. It is powered by two 10-tonne (11-ton) electric motors, each one driving a separate propeller. Those motors have a combined maximum output of 800 kilowatts, although for the ferry’s usual cruising speed of 10 knots, an output of 400 kW should suffice.”

The ZeroCat™ will be able to recharge in 10 minutes when docked during the load/unload process. [Gizmag]


Inductive Charging Of Electric Vehicles: Conveniently Inefficient

Google Inductive Charging Station
Inspired by a post on, Wireless Charging for Electric Cars Is Cool but Totally Unnecessary

Inductive charging, or wireless charging, is the use of electromagnetic fields to transfer power from one source to another. It’s all about the coils and when inductive charging technology is applied to electric vehicles, it only has to park or drive over a pad to receive an electrical current and charge its batteries. No need to plug it in and you get a fully charged EV the next morning or while you drive. Siemens and BMW are partnering on a program to further this technology by installing a inductive charging station in the city of Berlin in two months.

My question: do we really need this feature to get people to purchase electric vehicles? According to Wiki, at its current best, inductive charging is only 86% efficient with the rest of the electrical current being lost as waste heat. Convenience takes precedent over efficiency and that really seems to run counter to the purpose of driving an EV.

We’ll see what happens. When the Rolls-Royce Phantom 102EX electric car rolls out, it’s set to have the inductive charging feature but it won’t be receiving the Jubbling patch. That’s earned by working through some inconvenience and in this case, all that would mean is that you actually have to plug your EV into an outlet.
