New project: Portable Flettner-Rotor (Longboard)

3D model available on

The idea come while reading “Symmetry of Sailing” by Ross Garret. The german engineer Anton Flettner was the first to use this physical principle as propulsion engine for a ship in 1922.

The still difficult part and open points to discuss that I have in this Winter project are:

  • Material to use in the main structure. The goal is that is light, when possible less than 10 Kilos,  but resistant since it needs to provide lift.
  • Motor weight: 170 g  Speed controller: 230 g  . Cables + Battery: Aprox.  2 K. Making a total of 2.5 Kilos weight.
  • Still open to discuss: At what speed needs the cilinder to roll and what would be the ideal diameter to provide enough momentum to move 70 Kg in a Longboard (I thought about 40 cm diameter).
    The chain relation between the motor and the cilinder to have the right speed and force. Ex: 10 spin motor: 1 spin cilinder
  • And to end the question: What kind of lift will this generate on a 10 Knots wind, coming from the optimal point, let’s say 90 degrees left or right from the cilinder.

I think that it can be a great way to make branding campaigns and to get visibility for a new product or startup.

#Remarketing hack explained. How to use the social banners on your own benefit

I’m sure this happened to you too. After searching for something on the internet, banners showing exactly this product are following you on any other website you visit. And specially on Facebook!

Because you surf the web with Facebook open don’t you ?  Then you must be aware that on 90% of any website there is some kind of facebook plugin. That means facebook knows almost all the sites you visit.

Now why don’t to use this power for our own benefit ?

Follow this simple steps:

  1. Put an article for sale on eBay
  2. Visit amazon and search for the product you are selling
  3. Wait until amazon banners follow you in all social networks
  4. And make a comment in their advertising pointing to your own eBay cheaper sale
  5. Get amazon paid traffic for free in your own benefit


Positive Groove playlist 1

At the start of this year I got tired of Spotify advertising and I got a premium account. So I started making public playlists and sharing with the friends at work and posting it sometimes the new editions in Facebook and Twitter.  This generated some good feedback so I though about sharing some of them here too.

The idea is to make list with fresh groovy music. Positive, vibrant, soulful and sexy.

Here are some of my favorites:

pg_bamboos“The Wilhelm scream” fromThe Bamboos opens the playlist. They have proven that they are more than meets the eye; over five acclaimed albums, their evolution in sound and style has consistently confounded and exceeded expectations.

“Nothing prepared me for just how fresh and vibrant the music of The Bamboos is” – Notion Magazine (U.K)



pg_metropolitan_jazzMetropolitan Jazz Affair is France based Jazz band  featuring Mr Day, Rongetz, Benjamin Devigne, Patchworks. They have really awesome tunes, if you like nu-jazz check them out.



wolf_myer Wolf is the head of Myer Orchestra, coming from Linz, he worked as manager for companies like Sony Music Austria and played more than 500 live shows as a session drummer in the last six years.



pg_roberto_fonsecaRoberto Fonseca was born in La Havana. Pianist, composer, arreglista and professor of piano’s inclination to music begun at age four with his interest in percussion instruments.
In this playlist we feature “El soñador esta cansado” an awesome track with a heart-taking piano performance. en venta con más de 14.900 indexadas en google está en venta en un precio estimado calculado a lo que daría el sitio en publicidad en 3 años. O sea, solo con moverlo de sitio o incluso quedandose con una copia de la instancia de Amazon AWS en la que corre, es una inversión que se recupera sola en 3 años o menos si tienen pensado hacer el sitio interesante o agregar más productos. Tiene entre 800 y 1000 visitas diarias, de los que el 90% son visitas desde España. Dentro y incluido en ese precio viene un administrador también, super rápido donde se pueden editar y agregar nuevos productos.
