I thought the spirulina farming was cool (though green bread was a bit odd to me), but it was the concept of seacrete to have calcium depose o electrodes and actually "grow" concrete structures that absolutely grabbed my imagination. I have been hoping to hear about this becoming a reality for such a long time. I am very optimistic about Blueseed and their approach to seasteading. I'd be curious to see if a hot war in the Sea of China changes anything. Hopefully it remains a curiosity.
