Here are the concept notes from today. The one we found most interesting is the SELF HEATING SHOWER SYSTEM "Generating Energy Through Water Movement".

+ Transforming water pressure of the existing plumbing installation (or at least the existing shower water cycle); with the following possibilities:
- Material that uses friction with water.
- Turbine + transformer = energy
- Split water path to increase pressure (like with the rivers)
- Body movement in the shower
- Chemical reaction
- Tap energy loss recovery
- Geothermal heating principle
- Silicone microtubes?

Anyway, here are the pictures from the rest of the drafts:

Abstract. An experimental investigation was performed on the flow friction and convective heat transfer characteristics of the ethanol–water solutions flowing through five sets of trapezoidal silicon microchannels having hydraulic diameters ranging from 141.7 µm to 268.6 µm. Four kinds of ethanol–water solutions with the ethanol volume concentrations ranging from 0 to 0.8 were tested under different flow and heating conditions. It was found that the cross-sectional geometric parameters had great effect on the flow friction and heat transfer, and the microchannels with a larger W_b/W_t (bottom width-to-top width ratio) and a smaller H/W_t (depth-to-top width ratio) usually had a larger friction constant and a higher Nusselt number. Entrance effects were significant for the flow friction and heat transfer in silicon microchannels, and decreased with the increase of dimensionless hydrodynamic length L and dimensionless thermal length L⁺_h. When L > 1.0, the hydrodynamic entrance effect on the flow friction was ignorable. For the developed laminar flow in silicon microchannels, the Navier–Stokes equation was applicable. It was also found that the volume concentrations had different effects on the flow friction and heat transfer. Within the experimental range, the effect of volume concentrations on the flow friction was ignorable, and the friction constants of the ethanol–water solutions having different concentrations were the same as those of the pure water. However, volume concentrations had great effect on the convection heat transfer in silicon microchannels. With the increase of the volume concentrations, the Nusselt number of the ethanol–water solutions increased obviously, which was attributed to the combination effect of the increase in the Prantdtl number as well as the volatilization effect of the ethanol. Based on the experimental data, the dimensionless correlations for the flow friction and heat transfer of the ethanol–water solutions in the silicon microchannels in a function of the cross-sectional geometrical parameters, entrance effect and volume concentrations were proposed for the first time.

15.02.2010 Meeting Natalie and Fernanda

With the intention of better definning this product-to-be we just pointed out this few notes:

DEFINITIVE POINTS
- Used in the shower.
- Connected to pipelines.
- Alternative electricity: Power Turbine
- Creates awareness
- Brings a real profit to the user (investment not just luxury gadget)

MAYBES?
- In/visible
- Docking station
- Modularity
- Heating system for the water (hybrid with the usual gas)

We think it's important that the energy created with the turbine by the natural shower water cycle is used in a smart way, so could it be that we use the existing installation to heat the water that we use?

Here's different versions of an analog that works with electricity, directly on the shower head to heat the water. We could then substitute the electricity...

Energie producing turbine

This turbine can be stuck onto a water-tap and as soon as the water runs it produces enough energie to charge your mobile phone for example. (220v)

Sony Technology

Here's the technology that Sony uses in their eBook Reader. It's basically a polarized pigment that reacts to the screen by going up or down. That's what gives it a high resolution and paper-like sensation.

Meeting 12.02.

Meeting 12.02.2010


Statement:

USE the cycle water as it is, not change it necessarily!

Sketches/Ideas:

Using the already existing water-pressure in the pipe to produce the energy needed to run a shower-radio/temperature/meter/consumption/countdown/Chronometer etc. via a small turbine.
Why? More fun whilst listening to the radio under the shower and being aware of how much water you use/ how long you shower.

How does it work:

Left side of the following picture: the tiles in a shower.
Right side of the following picture: what happens

1. When the shower is switched off - it lookes like ususal tiles.
2. As soon as the shower gets turned on, the Radio gehts on with it (the turbin rotates because of the water passing in the tube and energy gets produced)
3. The screen appears on the right side of the tile, while a digital symbol of a turbine rotating on the left symbolizes the movement of the turbine/the water in the pipe
   
4. the tiles next to the "radio-tile" on each side (to the right and the left) are a "speaker-tiles" for the radio (the surface-structure of these tiles could go on as a pattern over the whole wall
5. when the water gets turned off- the radio stops as well! (or could run a little while longer with an integrated short-term-battery that recharges itself during the next shower)
   

Which programms are interesting:

• The touch-screen enables an easy "ipod-like"-way of flipping through the programms.
• only digital numbers are shown on the screen (keep it simple)
  
• No buttons needed where water could run in (only one plain surface)
• Nothing visible when its switched of - its just a tile!

Interesting parting point? Bedol Water Powered Clock

http://incrediblethings.com/home/bedol-water-powered-clock/

If you're sick of buying batteries and want to find a more eco-friendly solution for as many devices as you can, then you'll love the ingenious design of the Bedol Water Clock. This marvel of modern science runs off of pure H20 and nothing else... no batteries, no wires, no chemicals and no gimmicks. Fill the tank with water and you won't have to refresh for almost 2 months. The translucent blue siding and silver face give this cool desk clock an attractive modern appeal.

This post can be updated with more specific details, but I find this material very interesting.

Sebastian Müller about dry cleaning

The drycleaner is a very got finding...

...why not clean with something else than water, such as compressed air (you know people do this in the workshop if they dusty, they blow their hair and clothes clean with the compressed air guns, Natalie can tell you from Stuttgart!)
You may actually go into daniels workshop tonight and make your own fieldstudy (but do not blow into your eyes...).

You should anyway do more fieldstudy, there is fantastic stuff in the internet, books and your heads. However you have the extraordinary gift that YOU LIVE IN A METROPOLE. So why not going out in Paris streets and asking some posh Parisienes how they what was whichout water...and Victor is in Brasil...
Other design students have to hang up in Lahti or Darmstadt. So be consciouse about using this opportunity, go out and speak to the people (this also a big MEDes benefit that might be reflected in the design process of this project! ) Make photos/videos

Notes from Skype with Thomas, Fernanda and Sebastian 05.02.2010

—Our design should illustrate our attitude towards water.

05.02.2010

—Research in methods of filtering the water, different ways of filtering, the most interesting way of doing it. Shallow vs. interesting ways. 

Victors proposals: Modules create different cycles. The water does different things depending on the configurations of the water.

Maybe these two can be combined. ?

—Try to understand water; cycle, parts of the cycle; filtering, use of water ....

Eco-friendly Bath

http://www.ecofriend.org/entry/eco-gadgets-daspa-shower-recycles-shower-water-for-a-green-massage/
Similar system to what we're looking for.
Recycling water cycle. Cons: It uses electricity and kind of darkens the eco-friendly part.

3.02.2010 First directions

We've been talking about which direction the product should take, and defined some points that we would like to make definite:

1. The water flowing into the bathtub in a water spring way (bottom to top) - more natural.

2. Waterfall-feel shower

3. Regulatable waterfall as for one or two users (length)

4. Circulation/water cycle with a limited amount of reusable water. (Linked to other water systems e.g. wc?)

5. Adaptable depth of tub.

* Lying on your belly possibility to relax under "the waterfall".

Note: The images above ONLY illustrate the ideas behind, no formal references should be taken.
