Last week I had a meeting with another algae expert who specialises in fresh water algae. From what we talked about it looks like we might have a couple of problems.
First, I will need to maintain the temperature at around 18 Deg C. This I had a look at over the weekend and with out active cooling the best I could do was 23 Deg C. Come summer time I expect the temperature of the lab to go up to about 30 Deg C. The could cause the algae population to crash and encourage the growth of other, toxic, algae.
Second, I was hoping this would form part of a cyclic system that we will need for sustainability reasons. The waste from one system would form the input to another. As such I was hoping to use urine as a food source for the algae but this probably wont work as it will have some important trace elements missing. I will have to look at this again.
As for this week, I am concentrating of the Earth Day lecture. That lecture will take place at Umeå University on the 21st at 19:30. The subject will cover the proto-technate as a means for moving from today's unsustainable system to a future sustainable system.
