The Navy's new Riverine Command Boat (RCB-X)  (Source: NAVY.mil)
Navy hopes to cut its fossil fuel consumption in half by 2020

It seems these days that many people/organizations are trying to go green. We have companies like Dell installing solar panels in parking lotsnumerous auto manufacturers are selling/developing full-electric and gasoline-electric hybrid vehicles; and even homeowners look to reduce costs by using fluorescent lighting and eco-friendly building materials.

Not to be left out, the U.S. Navy is showing its "green" side with a new 49-foot Riverine Command Boat (RCB-X). The boat is powered by a 50/50 mix of NATO F-76 fuel and algae-based biofuel.

Although there is no talk about an increase (or penalty) in fuel efficiency by using the the fuel, it appears to be more of a policy decision with regards to stepping up the use of alternative fuels in the Navy's fleet.

"Going green is about combat capability and assuring Navy's mobility," said Rear Adm. Philip Cullom, director of the Chief of Naval Operations Energy and Environmental Readiness Division. "It is not just about natural security; it also strengthens national security. By having reliable and abundant alternate sources of energy, we will no longer be held hostage by any one source of energy, such as petroleum.”

As with all new and experimental technology, the price to use such fuel in this prototype vehicle is astronomical. And when we say astronomical, we mean it -- the Marine Corps Times reports that the Navy bought 20,055 gallons of algae-based biodiesel at a jaw-dropping cost of $424 per gallon.

According to Wired, the Navy uses 80,000 barrels of oil per day to fuel its ships and wishes to cut that number in half within a decade through the use of biofuels and nuclear power.

"First and foremost, energy conservation extends tactical range of our forces while also preserving precious resources," Cullom added. "Our goal, as a Navy, is to be an 'early adopter' of new technologies that enhance national security in an environmentally sustainable way."

You forgot documentation.

The lounge seating aboard a military vessel comes with a price tag of around $10,000 a piece. That includes not only the over-engineering of that piece of furniture, but the documentation of:

- All the chemicals that went into it
- How those chemicals react to other chemicals
- How those chemicals react to heat/cold/pressure
- How to safely extinguish it should it catch fire

All of this information had to be gathered through expensive laboratory study.

Then if later, they need more of these couches, there will be no economy of scale and you will see them cost 2-3x as much. This is acceptable to the military as these couches would be the exact same as the others and the old documentation would still be relevant.

To you, it's just a couch, to the military, it is a piece of equipment that represents a potential chemical hazard.
