spironlina

spirolina is an edible algae that needs only water, urine and iron (from rusty nails for example). However, it needs quite a warm climate. In colder places it is only possible to grow it in a greenhouse in summer. A possibility could be to pump it through a wood stove or compost heater.

aphanizomenon flos-aquae (AFA). apparently this has more chlorophyll than spirulina, needs less salinity, has more calcium, and importantly, can live in a colder climate. But it seems it only grows naturally (not cultivated). AFA and Spirulina Compared


tempeh:

Tasty indonesian soja with mould grown on it. The difficult thing is keeping the temperate constant. tempeh needs to be at about 32 degrees C for about 22 hours. Not a problem if you live in indonesia. If it gets colder than that for some time period, it seems it still works but takes longer, eg: on a woodstove which goes out at night but you light it again in the morning. but there is then increased risk of contamination with other bacterias. If it gets too hot the mould cannot survive.

electric incubators are easier to regulate temperature but less ecological and use too much power to realistically run from batteries. typically an isulated box (eg: an old refridgerator) and a heating element (eg: 40 or 60w light bulb). The simplest way to regulate it is with a dimmer switch (this works quite well). but leaving a dimmer set external temperature changes (eg: at night) and towards the end of the process the tempeh begins to produce its own heat and the temperature rises.

Another tricky thing is how to save the spore so you can make more and dont have it keep buying tempeh starter. you have to leave the tempeh in the incubator for longer (cut a thinner piece for more surface area and to not waste the middle part). the black powdery stuff is the spores. these can be scraped with something sterile to collect, or just take the whole piece of spore covered tempeh and dry it out (eg: on the stove) and blend it/grind it to a powder.

psbook in.ps out.ps  # reorder the pages to make a book,  
psnup -s1 -2 book.ps booklet.ps  # shrink to 2 pages on each A4 side
ps2pdf  #convert it back to a pdf
lpr -P myprinter -o page-set=even -#1 infile.pdf   # print the even pages
lpr -P myprinter -o page-set=odd -#1 infile.pdf    # print the odd pages
