High Density Vertical Algae BioReactor

I hadn't heard of this process. This sounds like an interesting alternative to fossil fuels in the cases of powering large vehicles such as trucks and airliners where wind, solar and electric are not feasible alternatives.

The Holy Grail in the renewable energy sector has been to create a clean, green process which uses only light, water and air to create fuel. Valcent's HDVB algae-to-biofuel technology mass produces algae, vegetable oil which is suitable for refining into a cost-effective, non-polluting biodiesel. The algae derived fuel will be an energy efficient replacement for fossil fuels and can be used in any diesel powered vehicle or machinery. In addition, 90% by weight of the algae is captured carbon dioxide, which is "sequestered" by this process and so contributes significantly to the reduction of greenhouse gases. Valcent has commissioned the world's first commercial-scale bioreactor pilot project at its test facility in El Paso, Texas.

 Here is another video on an algae bioreactor that is hooked up to to the smokestack of a fossil fuel power plant and not only captures 80% of the smokestack's CO2 emissions, the algae actually use that CO2 as food to grow and the result can then be refined into clean-burning biofuel... Unbelievable.
