My startup is working on novel microalgae photobioreactors - we are raising an angel/pre-seed round right now.
Our system is far more energy and space efficient compared to PBRs and raceways - we do this via a proprietary mechanism that greatly increases surface area to volume ratio of liquid water in our reactors. Feel free to drop us a line at info[at]skyfarmclimate.tech
- rengler33 4y agoI used to be on a research project that attempted to do this with a fungus/algae mix because when grown together the fungus suspended the algae throughout the column of water. That was a fun project that had it's funding pulled, and then I had to get into software engineering to make a living. What's the basic way of accomplishing your improvement?
- L_226 4y agoI can share further details by email, but the gist is we enable much faster gas exchange for microalgae cells compared to existing systems, inside a unique reactor design that gives us some other benefits for common cultivation processes.
- hanniabu 4y agoWhat do you dto with the algae after it has grown?
- L_226 4y agoSell it
- CatWChainsaw 4y agoAre you by chance growing spirulina algae? It's a popular supplement.
- L_226 4y agoNot at the moment - but it is an option for the future. Technically it is a cyanobacteria not microalgae
- merry_flame 4y agoTechnically both…
- hanniabu 4y agoYour website makes it sound like you're growing algae for co2 capture, but if you're selling it and not sequestering it then what's the point?
- L_226 4y agoWe're selling it as biochar, sorry should have specified.
- merry_flame 4y agoWeird. So you are supposedly beating everyone in terms of yields and yet focus on producing something worth even less than protein per kg. Wouldn't it make more sense to cream off the market on higher value-added products before scaling up while expanding into increasingly low value products?
- cultofmetatron 4y agoif you're trying to sequester carbon.. bury it. anything else will allow it to be released back into the atmosphere anyway
- Wyoming23 4y agoI once read a comment from an expert in that field who said that it was essentially impossible to prevent contamination, and that they had to constantly test and then shut down and sanitize when they discovered a different species of algae in their system. How do you mitigate that issue? (And good news if you have a solution, that same person said they figured whoever solved that problem would be the world's first trillionaire).
- L_226 4y agoMitigation strategies are varied, you basically cannot guarantee there will not be any contamination if you are doing any kind of scale. We are looking at polycultures/consortiums (robust ecosystems inside one reactor), various filtration systems and high frequency monitoring. There are some others we won't publish (yet)
