Prairie-Masker Goes Green

SECNAV - if you want to make an effort to make the Fleet more fuel efficient and less reliant on fossil fuels, I have a suggestion.

Let's ignore the Green Lobby and paying 4-times the going rate for fuel, and instead benchmark something industry is already doing.
The Mitsubishi Air Lubrication System (MALS) was the first air lubrication system in the world to be applied to a newly built ship, and resulted in a substantial reduction in the ship’s resistance. Therefore, a performance estimation method using computational fluid dynamics (CFD) needs to be established as soon as possible to apply the MALS to general commercial ships.
As reported in Wired six months ago;
The boats, to be completed by 2014, rely on Mitsubishi Heavy Industries’ proprietary Mitsubishi Air Lubrication System (MALS). Mitsubishi claims that MALS can reduce CO2 emissions by a quarter compared with conventional dry bulk carriers. Considering the ships will carry about 100,000 tons including cargo, fuel and crew, that’s a significant reduction. The three ships ordered by ADM will be 131 feet wide and 777 feet long and will be built by Oshima Shipbuilding.
