Wind to Fossil Fuel to Wind & Electric

Ships and Boats are going " Full Circle" in energy for propulsion.

It is heartening to see the extraordinary progress in the different transport sectors despite the best efforts of self interest fossil fuel groups, individuals and politicians.

The impressive clipper ships took around an hour and hard work of 20 or more men to extend sails. This can now be done extending high tech ultra efficient sails in a handful of minutes and the push of a few buttons.

Digitally controlled aerofoils are now being retrofitted to tankers and container ships saving in the region of 15% to 25% on fuel and pollution without impeding cargo load or unload.

Solar panels are being placed on super yacht, wind powered yacht are now using water driven turbines for electrical supply for the boat. (The irony of a propeller creating energy not burning it).

Magnus effect "Spinning Rotors or Fletner Rotors" a century old technology is now implemented on ferries and cargo shipping.

This excellent 45 minute YouTube video gives excellent coverage of all the real world (not prototype) installations and the background into the development programs and technical functioning and challenges behind them. (Where to mount, (fix or move and manoeuvre is a fascinating challenge)
