New technique for harvesting algae with micro-bubbles

Scientists at Sheffield University have figured out a new way to separate particles of algae from the water that it grows in through the use of micro-bubbles.  This isn’t a brand new idea – micro-bubbles have been used to purify water and separate out algae for a while now – what they’ve figured out is a method of doing it cheaply and with much lower energy requirements than previous techniques.  This should reduce the costs for harvesting algae for producing food or biofuels – whether it’ll be enough of a reduction to make a difference is another question, but every little bit helps.
