20111116 General meeting

posted Nov 19, 2011, 9:03 PM by Cesar Harada   [ updated Nov 19, 2011, 9:03 PM ]


- Finding the right coefficients.
example :
Heeling Moment at 20º (kg*m) = 4106,61
Dellenbaugh Angle (º) 14kn wind = 22,25

- About testing order : 
1 - Bollard pull with Protei (
2 - Pull with the boom.. 

- WIll make research on Old Sailling/Fishing vessels .


Helping setting the exhibition of Protei in berlin Haus der Kultur Der Welt.
Seb`ll be at the opening, and the studio is coming along!


Answering the question : "what do we do of oil booms?":
- burn them / bury them
- squeeze them IF WE USE squeezable material


Mentions a ship that recycles the collected oil at sea.
Alvaro explains about : FPSO (Field Oil production Offloading) : 
Piem said : 
Last week we (Alvaro and myself) were supposed to go to the cleandrinks event, but missed the boat to RDM, so we never got there.
But we have a direct contact with Jouke Goslinga, who rents the space. My action: find out if we can rent the space for a short perio over summer. Because that seems to be the consensus, right? Work on small tasks separately, then bring all the people and knowledge together to one place and build next big version...

So if RDM does not rent for let's say three months, we might as well forget about it.
If they do, we have to fnd sponsoring. It will cost around €700 p/month
And we have the BLUE thing coming up in San Francisco, right after the summer.

Cesar asks :We do not know if we can use the machines… ?
Piem : I guess, if we are official renters... but let me double check the conditions.

for the costs, they are as following;
1 m2 equals E55,- ex VAT (btw) per year
a charge of 17,5 % is added for "general areas such as walking/driving ways, toilets etc.
a servicefee is billed upfront , 1 m2 equals E25,00 ex VAT (BTW), this includes surveillance, sercured admission (being developed) cleaning,
internet basic (high speed internet on demand is seperatly offerd, heating etc>), at the end of the year the real costs are calculated and then the difference is billed with a maximum of E 27,50 per m2.

For instance;
Lot A5 is 96 m2 (netto)
so that means 96 x 1,175 = 112,80 m2 (bruto of BVO in dutch)
then 112,80 m2 x E 55,- = E 5.280,00 per year (ex VAT)
service fee (upfront) then is 112,80 x E 25,00 = E 2.820,00 per year (ex VAT)
so in total E 8.100,00 per year
or E 675,- per month (ex VAT)
<worst case scenario for service fee is + E 2,50 per m2 BVO is billed
afterwards => 112,80 x E 2,50 = E 282,00 per year (ex VAT)>
so say for less than E 700,- per month (ex VAT) a lot like A5 ( 10,5 x 9 m2) is yours.
They do talk a lot about "year"... not "month"
Talking about shipping from Rotterdam to San Francisco. Probably pretty long and expensive.


Suggesting research package :
1. Bollard pull from sail surface (Alvaro and Etienne working on it)
2. control trajectory?
3. reduction of turbulences with no centreboard, nor rudder?
4. lateral lift profile?
5. Upwind sailing (with 2 sails) ? :
5. gain of stability with articulated hull following waves motion.

[16/11/2011 15:51:48] Alvaro Takiuti: Bollard Pull Experiment I have it set, I will send a sketch today,

- will send wing area / lift coefficient

- create a page for physics experiments

- create a page for Protei_006 that lays out clearly our findings and documentation.

- Protei's strategy :

the main objective of Protei is to serve the environment, which is the opposite of current way of doing business :
that's the current way...
but Protei flip that model upside down : 

Business as usual model => Nature, Humans, Technology, Money

To achieve environmental impact, Protei innovation can be implemented for 2 main applications :
1 - Sensing
2 - Cleaning

These impacts have - in fact- very different requirements
1. sensing can be rather small : 1m is good format to start with
2. to clean, you need a lot more power. 6meters may be good 

Protei : prototypes to products

So how do we connect the concept of shape-shifting hull, the prototypes we made, and the environmental applications ?
The priority -and simplest - seems to be to develop a 1M Remotelly controllable Protei
Once the design of 1M RC is stable, we can replace the RC components by Arduino + Android
So, first develop Protei 1m RC as simple, cheap and rugged as a "Toy", and simply replace / upgrade to 1m with Arduino for science applications 

Now, why am I having a manned 6meter Protei on the right side of the image ?
Because it is the usual way of developing larger autonomous sailing robot : making a manned sail boat - and replace the human by battery + motors + sensors + AI

Also sailing this crazy shape-shifting boat will be incredible fun and we'd learn so much from it.
- V2_ Piem Wirtz: sounds good!

Also for testing the limits of the technology, a good sailor / kite surfer / surfer would be amazing
Imagine the world best sailors/ surfers on a manned protei! Would you be excited to sail a shape-shifting sailboat ?
- V2_ Piem Wirtz: oh, yes..

Can you imagine sailing at high speed in a narrow, ballasted torpedo shaped sailboat ? And we can pull long tail after that crazy machine without the hassle to do electromechanics.
- V2_ Piem Wirtz: any timeline set to this?? What should be ready when, and who can do what?

But this time, to develop the proto, let's not repeat the mistake we made this summer. We dont design the boat and try to fit exotic electronics, we start by standard electronics, and develop the hull around it : like this : 

Protei 6m Dev


with the milestones, 4 main milestones :
- 1. 1m remote control
- 2. 1m Arduino + Android semi-autonomous
- 3. 6m manned
- 4. 6m unmanned
Over the course of 2 years

And I started some expenses, revenue schematics :
To see what is going to cost us money, where we could generate revenues .

Products, Expenses, Revenue

And these are the possible markets and applications :
