I’m sure you’ve heard of ferro-cement boat hulls (popular a couple or three decades ago among the home build crowd). Well, now we’re getting technology to "print" with computer controlled machines various concrete and plastic based constructs.
For the first time, the US Navy is using a new breed of sailing ship to deliver military equipment, a move that can potentially reduce fuel costs by 20 to 30 percent, or roughly $1,600 a day per ship, according to the ship’s owners.
The Navy’s Military Sealift Command (MSC) has chartered the "kite-assisted", fuel-saving 400 foot, MV Beluga to deliver Air Force and Army cargo to from Europe to the US.
Launching today (Tuesday, the 22nd) on a voyage from Germany to Venezuela, the 462′ MS Beluga will be using a SkySail to provide an expected 20% fuel use savings. Pretty slick as we come full circle from sail to power moving back to sail. Wonder when we’ll see more "personal" versions of this type of sail.
