Algae

For SpaceNut ... we had no topics devoted exclusively to Algae

To start this new topic, here is a report of academic research combining with ** really ** practical commercial application:

Tackling the seemingly endless number of issues climate change poses is going to take tons of creative solutions. Luckily for all of us, there are lots of people out there taking the challenge seriously; deploying autonomous machines to clean out the world’s rivers, for example. Or feeding cows seaweed to limit their methane output. Or, in the case of the independent brewery, Young Henrys, using tanks of algae to mitigate its carbon footprint.


DesignTAXI reported on Young Henrys use of algae tanks as climate change-busting devices. The brewery, located outside of Sydney, Australia, teamed up with the University of Technology Sydney (UTS) for the endeavor. With both organizations aiming to neutralize the carbon dioxide Young Henrys produces as it brews its beer.

In the video, which you can watch in full here on YouTube, Young Henrys co-founder Oscar McMahon and Dr. Janice McCaughly, walk through the process of how the algae consumes the CO2 produced by the brewing process. (The relevant part of the tour begins around minute 34.) And it is simultaneously magical, primordial, and a little bit like something you’d see on the set of a Bill Nye TV series.

As McCaughly notes, the tanks of algae—which contain nearly five million microalgae cells—absorb atmospheric carbon dioxide that Young Henrys fermentation vessels produce. (Yeast gobbles up sugars to create alcohol, and CO2 is a byproduct.) The algae then uses light to convert the inorganic molecules into an organic one: glucose. In the process, the algae produces breathable oxygen, as well as biomass usable as a nutritional component, or even for plastic fibers. In total, a single one of Young Henrys breweries can produce as much oxygen as a hectare of Australian forest via photo synthesis.

Perhaps just as important as Young Henrys use of algae tanks is its use of solar panels. The company says that it has two community solar farms that provide their breweries with power. And because the algae tanks undoubtedly need electricity, that’s a good way to make sure the whole process stays (a bright, neon) green.

Re: Algae

The search engine is a bit picky... here are just a few such topics where its Algea misspelled

Utilization and Issues of Algae for Martian Colonization
Current experiments on algea, lichen etc.? - Anybody doing this stuff
Algae food
life support proposal - water/waste recycling, food production.
Wastewater Treatment
Crops, Aquatic


The big issues is that there is many varieties of Algae and what to do with each....

Re: Algae

For SpaceNut ... thanks for looking again for algae ... This morning it ** did ** find Utilization ...

If it had shown that yesterday I'd have used it ...

However, the new topic is available for everyone in the Solar system, and not just Mars.

On the other hand, your Post #2 does give a future forum reader a snapshot of related topics they might investigate.

So I think we have the topic covered.

I'd appreciate someone commenting upon the essence of the article, which was that making beer leads to production of Oxygen ...

That should be of interest to future space dwellers of all places and times.

Re: Algae

quote from a discussion in one of those Booze, Art, Music, Drugs, Relaxation, Alcohol or Downtime threads

Interesting reference on the possible use of microalgae to produce ethanol.
https://www.intechopen.com/chapters/47886

Comparison of yields per acre:

Wheat: 277 gal/acre.
Algae: 5,000–15,000 gal/acre.

We would need to produce a blend of fermented micro algae that results in pleasant flavours that people will enjoy.  But the much greater yield of micro algae and its ability to grow in panels and thin tubes, gives it an enormous advantage over other foods that we might grow on Mars.  And it has the advantage that we can drain it into tanks at night time to avoid it freezing.

One of the key enabling technologies for human colonisation of Mars is our ability to grow micro algae and combine and process these algae to produce foods that are palatable and nutritious.  Without this technology, each human colonist will have to be supported by hundreds of square metres of heated, pressurised greenhouses.  These would be very expensive to produce and energy intensive to operate.  A large part of the estimated 100kW of power capacity needed to support each colonist on Mars would be taken up by food production.  Processed algae avoids almost all of this requirement.  It will be the cheapest way of making food and alcohol.

If the yield estimates above are to be believed, then a single acre of algae panels (40 x 100m) will yield around 20,000 litres of ethanol per year.  That is equivalent to 50,000 litres of standard 40% whisky or vodka or 500,000 litres of beer.

Re: Algae

The algae, micro algae and seaweed are not the same things....some can under fast growing are toxic...now if we are looking for fast grow to convert to fuel then that is good as we need that most of all for the energy levels of mars being by far less than earths.
Man needs food as well as other things from these types of organisms.
