Nanostructured Hybrid BioBots for Beer Brewing
This is a paper from the University of Chemistry and Technology in Prague, published in the American Chemical Society ACS Nano journal.
The bots are 2mm beads with yeast in them. They are dropped in the wort, sink to the bottom, ferment the sugars, generating CO2 bubbles which take them to the surface where the CO2 is released.
They then sink back to the bottom and repeat the process until the sugar is finished, at which point they are removed with a magnet and can be reused.
Why bother? (I hear you ask). The motion keeps the wort/beer moving, which speeds up fermentation, and the yeast is easily removed.
Follow the link to the paper. It is quite heavy reading, but the illustrations are good.
Note: this was accepted for publication on 4th April. Not quite 1st April, but suspiciously close!
