Good news: The 7gal river water culture is growing very well with a rich green color and microscopic examination doesn't show presence of other organisms. One...
3x3 experiment in 2 variables, each with 3 levels Variables: Nutrient concentration=0,1 and 3, Sun=1,2 and 3 Nutrient concentration in number of teaspoons per...
An additional unintended variable: 2) different nutrient densities have different colors due to the Floralicious brand's pigmentation. Although I picked the...
I tried a Solaroof-related experiment today. I bought a 4" diameter, 8' long flexible dryer duct and hung it from the garage. It was something like $10 at Home...
James, Solaroof does not contemplate mixing the algae and the foam. It is two separate systems. The roof has three layers of plastic creating two separate ...
And, I forgot to mention, you are neatly solving one problem I've been worrying over - how do I transport water 15 or 20 feet in the air without squishing the...
Hi James, Some thoughts: Have you tried a culture with just the bubble solution added to the algae to make sure it doesn't harm it? Protein skimmers for fish...
Hi James, Bobby That is right, I do think that the "cooling liquid" system that is used in the SolaRoof process to maintain the inner skin at the dew point...
Hey James, Faith has a good suggestion. Find a local greenhouse supplier and look for their lay flat tubing film - this is used for ventialtion duct. It...
... That's what I'm trying now. I've discontinued the foam column experiment and put the solution into a translucent storage container like the 7gal river...
... I'm not noticing green in the 7gal Miracle Bubble/river medium -- _maybe_ a spec here. This is making me question the value of this particular experiment....
... Looking around at the various possible soaps with known chemical composition, it becomes apparent that the proper way to proceed is to make my own soap...
... The 7gal river culture density is higher now and the color isn't as dark so I added 1tbsp of the 1-.7-.6 "GROW" nutrient. I've read somewhere that the...
James, There is apparently a standard for measuring density. I bought a "dip stick" from a company in Fla. They shipped it an expensive way, so it ended up...
... I was referring to the fact that I'm getting higher algae density in the 7gal river culture now. Its becoming problematic because when the algae gets too...
... I found a cheap and accessible source of ammonium sulphate: Woodburn Fertilizer "Perfection" brand ammonium sulphate. 20lb bag for about $3 It was the only...
... I got some Woodburn 16-16-16 fertilizer and some 40-0-0 (urea) fertilizer. I had to go to the same small farm feed store that I went to to get the...
We've had an ongoing discussion about this recently on the wastewatts list. The article cited in this news item is David Pimentel's study, which appears to use...
I run my car on B100, but if the fuel comes from new soybean crops then I can't feel too virtuous about it. Even if the fuel produces more energy than it took...
Hi, I'm new to the group. I hope someone can point me in the right direction or answer some questions. With all the problems with run-off of fertilizer etc....
Scotch, You got it - my grandaddy could grow soybeans and make a profit, but he never grew algae. (Actually he got an algae bloom in the farm pond, but he ...
Philip, Most algae blooms contain, over time, a variety of species. Most wild algaes contain only a small amount of oil. We do not know what works and how...
... Nope. Both cultures bleached out quickly in the recent heat. So what I've done is taken another container and added to it a couple of gallons of the...
... The translucent container with the solution of 40-0-0 and 16-16-16 has been sitting long enough to be thoroughly mixed. There are some undissolved...
Thanks for doing this and sharing your experimental results. I have a few questions for you. 1) Have you considered injecting CO2 into one of your experimental...
... An interesting phenomenon: The control was the only bottle in which the algae formed a mat at the top. The rest were more or less settled at the bottom....
... As of now #4 looks to be doing well -- even better than #1, which is suffering a slight discoloration of the green. I've now added 1gal of the Zarrouk's...
... That might be a good idea as an experiment to see how carbon limited the system is but I'm hesitant to invest heavily in that route due to the poor...
