New Device to Make Energy Efficient Biofuels

A team of scientists from the University of Sheffield, UK, has developed an innovative device that will make the production of alternative biofuels more energy efficient.The research team has adapted a unique bioreactor for use in the production of alternative renewable fuels, to replace fossil fuels such as petrol and diesel.

The team have devised an air-lift loop bioreactor which creates microbubbles using 18% less energy consumption. Microbubbles are miniature gas bubbles of less than 50 microns diameter in water. They are able to transfer materials in a bioreactor much more rapidly than larger bubbles produced by conventional bubble generation techniques and they consume much less energy. The team's unique adaption of the bioreactor and creation of microbubbles has the potential to revolutionise the energy-efficient production of biofuels.

  In the beginning, there were algae,
but there was no oil Then, from algae came oil.
Now, the algae are still there, but oil is fast depleting
In future, there will be no oil, but there will still be algae  
So, doesn't it make sense to explore if we can again get oil from algae?
This is what we try to do at Oilgae.com - explore the potential of getting oil from algae
