This infamous gas which is harmful to the environment, has also its positive side. Your forest-self-regulation fantasy is just that. And thus no additional pump is required for this CO2 scrubber. Now add the algae sample we took earlier. Leave enough space at the top of the bottle that the water doesn't bubble out.With a couple of days the water will begin to turn murky and then green. I don't recall the depth that they were aiming for but obviously enough pressure to keep the dry ice from boiling away. Can the captured co2 be sequestered in plants? So when air is bubbled into water, CO2 will dissolve in water while the rest of the air just bubbles out. The point behind the pump is not just circulating the algae, but forcing CO2 into the water from the atmosphere at a faster rate than can be absorbed through the water's surface at a calm state. 5 years ago Trust me, that's all the algae you're going to need.As an alternative you might check with a friend or neighbor who has a hot tub. How would such artificial all-encompassing ocean structure be capable of withstanding the direct contact with ever-lasting bitter coldness of interplanetary space? Question In part I the scrubber consists of a 2 liter reactor vessel and a small aquarium air pump. We're going to drill a hole in the center of the plastic cap, insert a piece of 1/8" rigid plastic tubing, glue that in place. It is worth to equip underground shelters and bunkers with carbon dioxide scrubber because during the first hours of a nuclear attack, smoke, carbon monoxide, and radiation particles could overcome the ventilation and … At an extreme, you may publish a part-built project if you cover an important technique in doing so. The principle of fixing carbon with plants depends on the plants growing and storing the fixed carbon in some fairly stable manner (for example as wood). And if you took the trouble to look around this site, and to read some of the other projects here, you would realise that my comment was meant as a subtle reminder that Instructables are for showing things you have actually made or done. You didn't know this, because your fantasy-forests would already be busting at the seams if you were right. 3 years ago. We have extensively harmed our planet by following a careless and profligate lifestyle. Strata air-powered active scrubbers have built-in fan systems that actively circulate air through the scrubber and push it out through soda lime chemical cartridges to scrub the CO2. 'Don't burn fossil fuels' is the only real mantra here ;-), http://www.gallactronics.com/2013/12/solar-co2-scrubber.html, MAKE ENERGY: A US-Mexico Innovation Challenge, Design and 3D Print Your Own Phone Case (in Fusion 360). "Plant some trees..." The CO2 we've released has been in an underground carbon bank for tens of millions of years. However due to the poor concentration of carbon dioxide in the air, this process may not be as effective as it sounds. While we're not concerned with pure algae cultures at this time we want to reduce the number of miscellaneous micro-organisims we include.Once we've obtained a reasonable sample we're going to breed the algae in order to produce the feedstock for the scrubber. They are inexpensive and should be commonly available:1 X 8' 1/4" aquarium airline tubing - PetSmart Top Fin brand or ACE Hardware flexible plastic tubing1 X 3' 1/8" inch rigid plastic air hose (3/16 outer diameter) - PetSmart Top Fin brand1 package 6 air stones - PetSmart Top Fin brand (also available individually)1 x 2L Clear Plastic soft drink or water bottle with screw on top - Recycled1 x 2L de-chlorinated water for breeder reactorOn the next page we'll learn more about dechlorination. If you took the trouble of reading through before commenting...I have mentioned that this is only a concept project and still needs to be tried out. No, a breeder reactor is not the cornerstone of a secret WMD project. ((Or search engines are shipt)). It can be used as shielding gas for welding, extra fuel for a greenhouse, make fizzy drinks fizzy .. that sort of thing. on Introduction. At 40C and at normal pressure conditions, about 600ml of carbon dioxide can dissolve in 1L of water while the solubility of nitrogen and oxygen is a mere 10ml and 20ml respectively. On a legal note, you have not shown that you have permission to use the images you have googled, not have you cited their source. Would a double layer acrylic aquarium wall with a hollow core (diameter 100 m) be capable of providing CO2 scrubbing powers to a space ship's small crew (of 9)? I have no relationship with any of these stores or products. How could you not realize this? on Introduction. Save enough medium from one of the lightest bottles to reseed them. between 1% (all land crop plants mildly pessimistic) and 8% (good algea and LED lights, i though i heard a 30% once upon a time?) Mineral water is an excellent supplement for trace minerals not found in Shultz nutrients.In Part II we'll talk more about culturing and cultivating algae and learn how to make a true algae nutrient medium. I'm planning on said bunker to comfortable support up to 6 people should my family become that large. this will help, but i'm not going into the rest of my calculations and guestimations unless someone replys https://en.wikipedia.org/wiki/Photosynthetic_efficiency Anyways, i guestimate you'd need around 4000watts of power continously lighting plants for minimum viability of this idea, you may require much more. Although a brilliant concept, the present technology is still very expensive and not perfectly sound. Different folks have different tolerances for chemicals and some folks might have more or less aggressive chemical policies. http://www.eia.doe.gov/cneaf/electricity/page/co2_report/co2report.html, http://www.pubmedcentral.nih.gov/pagerender.fcgi?artid=546951&pageindex=1#page, Design and 3D Print Your Own Phone Case (in Fusion 360), https://en.wikipedia.org/wiki/Photosynthetic_efficiency. Well, let's suppose I make it in my house. [Source: Sustainable Energy Without the Hot Air, http://www.withouthotair.com/c1/page_2.shtml]. The carbon has to go somewhere - if you removed most of the algae every few days and poured it down the drain, letting the remainder regrow, the scrubber would work because the fixed carbon (in the form of algae) would go down the drain. In later parts this basic design will be expanded provide more flexibility and increased production. Planting a tree locks carbon up in a tree for a number of decades, then re-releases it when the tree dies. Is there any other plants that can be used? That is a violation of the site's terms of service. All I'm saying is that many factors has to be counted in. 5 years ago. On a bit of a tangent here, but sticking with the carbon capture and storage that you were talking about. The end results were that you could not live indefinitely in an enclosed ecosystem. The reactor as described would fix carbon as the algae grows to saturation (a few days) and after that net carbon flux would be zero. Where did you get this faulty idea? Algae like warm temperatures so a healthy sample might easily be available before the hot tub cleaning cycle. I am not convinced this carbon scrubber would have a measurable impact on CO2 levels at this small scale. Ask any aquarium owner.So first we will obtain an algae sample.If you know somebody who has a fish tank the simplest solution is to ask them for an algae sample before they clean it next time. So here's the concept of a solar-powered carbon scrubber that could be the key in bringing down CO2 levels in the atmosphere. I'm going to address three of the things you said, because they prove how little you understand. Practically all of the sites have recommended scientific supply houses which offer exotic algae culture specimens suitable for advanced use in the latest biotechnology project.Fortunately we're not doing that and therefore we can take advantage of the fact that algae will grow anywhere in water unless one works actively to prevent it.
