Picasso Rewritable Halobacterium Salinarum Emulsion
I read picasso inspired from a broken camera and lens to make his one of the most important drawings of his lifetime. He was using a camera and lens broken and take parallel distortion images.
BUT one of the most interesting thing , his final image being taken from his camera lens fungus after 40 years of that camera being found.
One museum expert found fungus on the lens and fungus being scanned and his last known photograph developed. Its about the bacteriorhodopsin found in the fungus . That protein is in our eyes and saline waters makes waters colorful.
Halobacterium salinarum is the responsible of generation about above protein , it loves salt , 37 celcius and stirring.
If you mix rhodopsin in to plastic and enlarge an hologram , it records it for 1/10 second of time and than forgets. If you shine a photograph on to it and than in short time, if you shine a red laser on to the photograph , rhodopsin swithes to q state and never forgets again. If you shine a blue laser , it deletes the information.
10 million times rewritable. And millions times more detail than dvd.
If you prepare 10 plates for ultra large format , it lowers the costs hundreds times per year.
This article is a start point , highschool children makes their big hologram plates with growing that protein and put in to plastic media.
Once you accomplish a big film with it , it expands large and ultra large format in to the hands of many.
Here is a recipe.
Halobacterium salinarum Media
● 250 g NaCl
● 20 g MgSO4
● 2 g KCl
● 3 g NaH2C6H5O7 (Sodium Citrate)
● 10 g Oxoid Peptone
● 20 g Agar (if making plates)
● Stir Plate & Bar (or a Stir Stick if not available)
● 1 L Beaker
● 1 L Distilled Water
● 1 L Graduated Cylinder
● 1 L Bottle
● 2 L Flask (if making plates)
● .01 g – 300 g capable Scale
● Weigh boats and spatulas
● Optional: Autoclave tape and Pen
1. Put a stir bar into a beaker and put on a stir plate
a. If using a stir stick, just remember to stir the mixture with each new ingredient
2. Pour approximately 600 mL of distilled water into the beaker
3. Using a weighing boat, measure out 250 g of NaCl and pour it into the beaker.
4. Turn the stir plate on low
5. Repeat step 3 for the other substances except agar
6. Turn the stir plate up a little higher and measure out approximately 200 mL of distilled water and
pour it into the beaker
7. After this has stirred for a while and it looks homogenous, pour the contents of the beaker into the
graduated cylinder, holding another stir bar to the bottom of the beaker so that the stir bar will not
fall out. Add enough distilled water to the cylinder to equal 1L
8. Transfer to a bottle and prepare it to be autoclaved
a. If making plates, add agar to the bottle that will be autoclaved
