Okay, I've posted some pictures now - They're in the grougp's photos, under the album called Xuan's Biospheres. Also, on another note, I answered most of the...
In the .pdf from Paragon, they describe the enclosed ecosystems used on Mir and space shuttle launches. In the paper they say: "A final draw- down of...
Hi everyone who has posted a link to the website. There are a number of bad links (at least 4) so each of the owners should check their links and either...
For those who haven't seen this site, he has some "opinions" on "those" closed systems. http://www.fukubonsai.com/M-L2e.html Nick Now it is time to get back to...
nk1165, ... i believe these suggestions are part and parcel of the same thing. basically i think what can happen in an algae-dominated system is that they...
1) I'd think that increased oxygen would generate the greater benefit in a biosphere, since higher levels of oxygen will usually bring the ph up (or at least...
I have seen the same general critique in several aquarium-related forums. If I can paraphrase the opinion, it is this: the Hawaiian Red Shrimp-based...
I think we often loose track of what is the purpose of our experiment (closed sphere). - Is it to create a closed sphere that will last for decades, years or...
Here is a link to the Make magazine article: http://cachefly.oreilly.com/make/wp_aquanaut.pdf Here is the parent link with links to video downloads. ...
Excellent points, Nick. If I could just expand upon them a little bit... When defining goals, in my opinion it's not enough to just say "keep life going...
Well said Soupmanbrown (is that what we call you?). I pondered how to bring into the requirements the "ethical treatment of the econauts" but dropped it due to...
Wow! that mouse device you linked to is a neat idea. Looks like they are focusing on environmental regulation a lot (because the idea is that the project...
In fact the Earth does have mechanisms that regulate humidity and other enviromental parameters. We tend to call them cold fronts, warm fronts, summer,...
Back in high school, I made an extremely successful sealed biosphere. I used a 1 gallon plastic juice bottle, aquarium water, aquarium gravel, plants called...
Xuan & nk1165, You both make really good points. On a philosophical level, I really agree that the goal is to create a system where lots of things can thrive,...
So I read the Make Magazine article and decided to take it upon myself to create the biosphere as described. It was quite easy and I'm fairly happy with the...
I made two biospheres today and only added the snails (waiting to get the shrimps later) and I was wondering if celery would be a good temporary, if not...
Generally, you don't want to introduce extra food or nutrients that don't have some other purpose. These will just encourage algal growth. I think algae are...
I was recently given a 14" (or so) glass bio-sphere with a wooden base. The only problem is I believe it is completely dead. It had been stored in a basement...
Well, there could be a number of reasons for why the animals in your biosphere aren't as active under low light. One possible reason is that high temperatures...
That helps alot. After trying the celery I realized the snails were dying, meaning they didnt have enough food and/or oxygen which was good to know before I...
First of all....The sphere creatures need light, thts why they died. So make sure to put the sphere near a window. Ghost shrimp (Costing $.30 sometimes less)...
Space? O.o What do u plan to do? Ride a plane and throw it up into space? XD Jk jk I think the underwater one is an awesome idea and so is underground. I want...
