The Pentagon intends to spend $400 million to develop a giant blimp which will reach an altitude of 65,000 feet and remain airborne for 10 years. The dirigible will be filled with helium and powered by an innovative system that uses solar panels to recharge hydrogen fuel cells. Werner J.A. Dahm, chief scientist for the Air Force describing the proposed unmanned airship as a cross between a satellite and a spy plane. The aircraft will provide intricate radar surveillance of the vehicles, planes and even people below.The project is supposed to reflect a shift in Pentagon planning that is more about the intelligence and surveillance operations, and less about expensive high-tech weapons.

  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
