Sailing with a kite!

The power of wind has been the most used energy source throughout the history of sailing. Currently, the use of wind power is limited to small boats with recreational purposes and commercial shipping depends exclusively on fossile fuels. What if we could avoid the carbon emissions generated by the thousands of cargo vessels that sail through the world every day? A german company has recently developed a wind propulsion system for cargo ships based on large towing kites. The SkySails system consists of an automated towing kite and a system that optimises the route according to the wind. When the wind conditions are suitable, this system can be used additionally to the propulsion of the ship’s engine. By using the SkySails-System, a ship‘s fuel costs can be reduced by 10- 35% on annual average, depending on wind conditions.

The first cargo ship with SkySails-Sytem, the Beluga Skysails was christened at Hamburg on December 15th, 2007. The future will tell if this environmentally friendly technology meets the requirements of commercial shipping. Maybe we will be the witnesses of a the start of a revolution in sea transportation.

A guitar that tunes itself


If you play the guitar, you must be used to spending a few minutes tuning your guitar. These days are over...
After many years of research Gibson has released the Robot Guitar, a guitar that is able to tune itself in less than a second. The instrument includes robotics technology that allows the processor to recognize the guitar pitch and send a signal to direct the six motor pegs to tighten or loose the strings accordingly. And that's not all, there are six nonstandard preset tunings that you can use to play different styles.
By now, this technology is only available for those who can spend around 2000 € on a guitar, but... who knows? Maybe in the future, there will be a robot in every band to make musicians' lives easier.
If you want to see a live performance of the Robot Guitar, check out the following video:
