It has been recently determined by the scientists that biofuel development is shifting from soil to sea, and to be more specific to marine algae.

Marine algae that are referred to as "green bullet" is being seen as science and society's best hope for a clean bio-energy source. Thus it would also help loosen broad dependence on fossil fuel, counteract climate warming, and power the vehicles of the future.

"Marine algae are the most efficient organisms on Earth for absorbing light energy and converting it into a natural biomass oil product, the biofuel equivalent of crude oil," reported Greg Mitchell from the Scripps Institution of Oceanography at UC San Diego.

He further added, "Algae yields five to 10 times more bioenergy molecules per area, per time, than any terrestrial plant. Nothing else comes close."

Algae have the upper hand against other biofuel candidates, such as corn and soybeans if seen from a sustainability perspective.

It should also be noted that with the help of salt water, algae can be grown on barren desert land, averting competition with agricultural cropland and the need for large amounts of precious fresh water for irrigation.

Basically, algae require CO2 for growth and are inherently carbon neutral, and they can suck up CO2 directly from industrial pollution sources. It is also astonishing to know that algae can feed off the nutrients in discarded waste water.

There are yet more hidden secrets of algae, which is that the rich protein left over from algae harvests can be converted to animal feed.

It is also believed that they can more efficiently produce many more gallons of oil per acre than any other source; since algae reproduce quickly (they can double their numbers in a single day).

Bernard Raemy, executive vice president of Carbon Capture Corporation said, "There is still a lot of work to do, but algal-derived biofuels have the potential to become a major source of transportation fuel."

Mitcheel added, "Given their advantages, I believe marine algae are not only the most promising option for bioenergy fuel, but the only option that can scale up massively at the global level."
