Dale, Good luck. You may want to feed them something. For my initial batch, I am going to use an "algae food" that Carolina Biological suggests. When I get ...
... I have to wonder if the dried spirulina you buy from the store has been totally sterilized. Has anyone tried just dumping a bottle of health-food store...
James, Carolina Biological ( carolina.com) has a spirulina (15 - 1900 ) for a modest price ($5.45 plus shipping). They will give you hints on what to grow it...
I bought an 11ft by 15ft by 10mil tarp for $20 from Home Depot. It's brown on one side and silver on the other. I then just laid it down, silver(reflective)...
James, I'm certainly no expert, but I don't think spirulina grows wild in the US. It requires very alkaline conditions. I like your pond design. We need to...
... Perhaps I should have said "cyanobacteria". According to a quick search on the web, cyanobacteria are very wide ranging and can survive neutral or even...
Just joined this group. Interesting. Algae is one of my hobbies. Does anyone know the lipid profiles of cladophora and spirogyra (fresh-water, of course)? What...
Tonight, I got back to the algae culturing. I sterilized the bottles and water. 1. I put 1 oz. of warm water in the peanut jar. I scrapped chlorine from the...
Day 3: Its a cool rainy day. Midday there is now both a green and a blue green coverage on the bottom totaling about 20% of the area. The pool has a deeper end...
Day 4: There was some sleet briefly last night. Today it was sunny and mild. Despite the mild sunny weather all day, growth appears to have stopped. Whether...
Glass reflects IR and transmits visible. Silicon reflects visible and transmits IR. A large area of silicon would be expensive. An alternative would be to...
Another night's activity: 1. Add five drops of chlorine killer to each bottle. 2. Add 1/4 cup of Instant Ocean to each bottle. 3. There should be a noticeable...
Hello! This is an unexpected bonus - I thought discussion of my little brainstorm had died. ... I think you mean silicA - right? Silicon dioxide, or quartz in...
No, I meant pure silicon. It actually transmits IR while relecting visible. I saw it demonstrated in applied physics class using an infrared imaging device...
... Fascinating, that property of metallic silicon. The trick then is to keep it in its pure metallic state... Glass can contain silica, but mostly it is a...
I just collected a few gallons of Columbia River water in a 4 gallon bucket, dumped another 20oz packet of 24-8-16 Miracle Grow into the bucket and then almost...
Another night's activity: 1. Test each bottle for salinity. You want 34 to 36 PPT. 2. If a bottle is low, add a 1/4 teaspoon of salt, agitate, wait for 5...
Marc, we do the hologram thing. We etch holograms on plastic and place over a polycarbonate skylight. IR is redirected, white light is sent into the ...
I must have missed the beginning of this topic. What is the "hologram thing"? sounds like a very creative idea. Can someone point me to a link for info? Thanks...
A few days later, the only change to report is the appearance of numerous golden-green spots up to an inch in diameter on the bottom -- mainly in the deeper...
Marc, we are gearing up to mass produce holograms on plastic film. We will use them for energy conservation as well as solar gathering for greenhouses. ...
Hi Neal, Couild you please explain your holograms a little better, or do you have a website with information about them? What exactly do they do/how do they...
Faith (and Nick), It is in the messages. Mark wants to use solar for two purposes. A holographic filter might be a way to do it. Relevance: one of those things...
