my first thought before reading the article was, "are we even talking about an electric computer here?"

There are all sorts… some MIT wonks built one that plays tik tak toe that's made of tinker-toys and powered by a crank… in Neal Stephenson's Cryptonomicon, a computer built from a church pipe organ is used to decrypt third reich punch cars… all quite feasible.

But yeah, this is algae-for-electricity… pretty cool regardless, but it does make me wonder if some sort of bio-abacus could be possible
