Greetings from Finland.
I have a plan how to adapt microalgae into animal farming. Spirulina can be also used to fertilize plants, in addition that it is a good feed to the cows etc.
I can explain my inventions in short, why we can make new generation PBR with this knowledge.
First of all, the key point for microalgae farming is nutrients.
If we are to cash out the promise of green technology, nutrients cannot be chemically made but instead organic.
As
far as I know, the biggest problem with organic nutrients for algae
isnt microbiological safety, but the dark organic liquid nutrient will
not allow the light to penetrate deep enough, to the algae medium.
For
microbiological safety aspect, I have developed new kind of aerobic
compost reactor which will exchange gases with the PBR. As the
composting progress is adjusted with electronics, we can simple
determine if the right microbes are working: just by seeing if the
temperature will rise high enough.
The compost reactor
separates the solids and liquid. The solids will be a part of another
process in the system but the liquid can be used directly to the algae.
Also heat will benefit the growth of algae and save some electricity by
that.
Mines etc produce waste stones, which arent suitable
for their company. There is many sand pits in Finland where these stones
are gathered and are waste.
As we leach the iron etc. from
the stones with vinegar, we can obtain the micronutrients for the
algae. In couple of weeks, clear vinegar will turn red from random
stones of those pits.
Someone would have to test the actual iron etc. contents of such stonevinegar.
As Spirulina is the most easy to grow in microalgae, we need to raise the pH.
This is made by producing lye from example wood ash.
Wood
ash is formed, since the system will produce its own electricity: with
wood gas generator. Hemp hurds are most beneficial to use as they
produce more cellulose, than forest, per year and are much easily
obtained into burning material by both cost to nature and wallet.
As
we most def will need more phosphorous, than normal biowaste/animal
poo/hay produces in compost: there will be need for special stones for
phosphorous.
For that we can use this method:
https://en.wikipedia.org/wiki/Phosphate_rich_organic_manureNow for the PBR.
Thin layer cascade reactors are the best. Since then we dont need to mind the mixing and the depth of the culture.
My invention here is, that we dont use a single cascade: but multiple, arranged geometrically.
Also, as TLCs are mostly used outdoors, we will grow indoors.
As we dont need to use commercially produced pressure CO2 it will make the growing much greener chemistry.
Since even 80% of the CO2 introduced to the algae will go into atmosphere, it is crucial to make closed loop system.
Thats why we exchange the gases with compost, which will use the O2 and produce CO2.
As
buffer, we can simple adjust the air stream go once in a while through
water and/or another container of lye, which will absorb gases to
balance the amount in the loop.
One point is that we dont
use monoculture. For humans, we would farm for example lactic acid
bacteria, spirulina and b. subtilis. For fish food, we would use other
kind of microbes and even zooplankton. For the fish, the reactor doesnt
need to be PBR but better instead a pond, as the zooplankton itself will
mix the algae liquid and exchange gases and zooplankton will not live
under constant mixing very well as it is hard for it to eat if the
liquid is moving all the time.
Also we would use other
inventions made by other scientists. One which is to blink the LEDs in
order to optimize the photosynthesis and prevent photoinhibition.
Another
one is to use tiny magnets to produce more biomass. This will make more
cost to the PBR but as neodyms are quite forever, it wouldnt be bad
choice.
If you look at the studies of the subject, the
amount of magnetism is very small so we dont need to many or big
magnets, but too strong magnetic field will decrease the biomass.
So, here is some of the information in blog.
Here are all the study I have used in the project. Also in the start is some pictures of the project and my videos.
As
I am just private person and dont want to commercialize, but more: to
help dozens of algae company to start in Finland and northern countries
overall, my best working companion therefore would be in the public
sector.
My best choice is, that someone like you, would
make these tests and prototypes professionally to decide if the system
would work as planned.

time bypass, I am afraid sooner or later, I will have to sell my
ideology of open source publishing in case some corporation would fund
the project.
Hope before that, public sector would come to co-operate so we can continue publish free.
