By now you your are familiar with the world land speed record of Green Bird (http://www.greenbird.co.uk/)

"Honey Badger" is the name of the Saildrone vessel which reach Hawaii autonomously earlier this summer

And may be aware of the accomplishments of Saildrone (http://saildrone.com/)

They are both the brainchild of Richard Jenkins who recently took residence in Alameda and teamed up with Google founders
Sergi Brin and Larry Page to design a Kiteboat:

" It was interesting work, and he was introduced to a whole new scene, one where out-there engineering projects like the self-driving car and augmented-reality glasses were the stuff of everyday life. Suddenly his 126-mph accomplishment seemed pretty insignificant. “No one cares about land sailing,” Jenkins thought, “but the first drone around the world?”

Jenkins realized that the wing he’d evolved for the Greenbird would be perfect on an oceangoing drone. Its tail simplified the process of sailing so much that even a robot could handle it. The bot would need only three moving parts: the elevator-like tab on the tail, the rudder, and the free-rotating wing itself. What’s more, only two of those parts—the tail tab and the rudder—would need power. A few off-the-shelf solar panels would provide more than enough. Jenkins knew from long experience that the fewer parts there were, the fewer parts there were to break. His oceangoing drone needed to be single-minded, bulletproof, and absolutely spartan.

It happened that Owens was working in the same boatyard as Jenkins was, though on a different project: writing software and building watertight, salt-resistant, pressure-tested controllers for a submarine project. He too was daydreaming about building the first around-the-world drone. Jenkins, a boatbuilder, met Owens, a hacker, on the shop floor in April 2010, and they quickly realized the obvious: They should quit their jobs and join forces."

The technology and design of the wing is going big. Much bigger.

Adventure Cat's Co founder Jay Gardner has been lobbying to see wing assisted ferries sailing on San Francisco Bay and has partnered with Jenkins
to build a scale model of the proposed wing powered ferry and has been testing the boat around San Francisco Bay over the past few weeks

Our mission at Wind+Wing Technologies is to create safe and reliable transportation vessels utilizing the abundant, natural resource of wind. All regions of the world have winds, and we are dedicated to harnessing this clean, free power by outfitting vessels with computer-controlled wings. The goal is to significantly reduce not only energy costs and our reliance on fossil fuels, but also emissions and green house gases.


According to Jay, who's vision Wind & Wing Technologies (http://www.windwingtech.com/projects.html) The testing has gone well,
and the ease and simplicity of the wing assisted 42' trimaran has been better than originally anticipated. Even the parts you think might present problems, mostly docking and departures are easy, thanks to the sails ability to feather. " It's actually has less resistance than a conventional rig" says Jay. He adds that the current testing with and without power on the 45' "Trilliza", custom trimaran, will present a study on the fuel consumption and efficiency of the winged trimaran. The wing is 350 sq ft and rotates 360 degrees on a tapered spar that is 15" in diameter. The wing Richard Jenkins designed for the Greenbird works beautifully. Jay owns a canvas shop in Napa and the were able to cut the lower panel to sit flush with the tri's existing deck. The were able to utilize Trilliza's existing mast step and only had to cut a hole through the deck to insert the spar. The wings tail simplifies s the process of sailing so much that a robot does the trimming. The robot controls only three moving parts: the elevator-like tab on the tail, the rudder, and the free-rotating wing itself.

It was by shear luck that Stan Honey caught wind of the project and introduced Jay to Richard, who was recently relocated just across the bay from Jay's Adventure Cat business at Pier 39. Jay had bee in talks with the the Navy in San Diego about an experimental wing they had designed. As it turns out Richards design was not only extremely cheaper but simpler in design.

The concept for the winged ferry is something Jay and business partner Hans Korfin had in mind since the 80's , but it was the steep price in fuel cost's that re-energized the concept. With diesel prices reaching near $5.00 per gallon on the spot market, Jay's proposal to the Golden Gate Bridge District's Jim Swindler was fortuitous in timing. "The District burns through nearly 1,000,000 gallons of diesel per year running their ferries," Says Jay, "We presented them with a 32 page engineering feasibility study done by Pete Melvin of Morelli & Melvin which showed a 42% savings in fuel probability PLUS a very large drop in emissions. With that information they were enabled to apply for grants from the Air Resources Board, which enable the project to move forward.


We spoke with Pete Melvin about some of the design minutiae regarding the wing assisted cat aka "Hybrid Ferry". Pete confirmed that "The wing will assist even on routes going to weather, so long as it not dead to wind, and even then, the profile of the wing presents much less drag than a conventional rig. The obvious benefit being a low angle of attack. The analysis shows substantial benefit on the low angle of attack" When asked if extreme breeze would be cause for concern, Pete indicated that the self feathering mode would nullify any excess wind resistance. If power is lost the wings can be shifted to a disengage mode the the wing would feather itself. As far as government approval, Pete expects 4-6 months for approval and 1-2 years to build the boats.

Wind+Wing Technologies has partnered with Photon Composites, pioneers in innovative computerized wing technology, to develop a demonstration vessel for ferry routes on the San Francisco Bay. The vessel is a 42-foot trimaran equipped with a computerized wing, specifically designed to harness wind power to significantly reduce fuel consumption and emissions. In January 2014, the demonstration vessel will begin test sailing five days a week, for three months, on the following ferry routes from the San Francisco Ferry Building to:

Sausalito
Richmond
Treasure Island
Alameda

The demonstration period will track vessel reliability, speed, and fuel savings during a varied wind season, all while replicating a realistic ferry schedule. Data compiled during the demonstration will be forwarded for analysis to Dr. Timothy Lipman, Co-Director for the Transportation Sustainability Research Center at the University of California, Berkeley. The data will be presented in a final report, which will be made available to the public, and will document potential improvements in air quality and fuel cost savings from employing this technology on San Francisco Bay ferry vessels. This demonstration project is made possible by a grant from the Air Quality Improvement Program (AQIP) through the California Air Resources Board (CARB), with additional funding and grant administration by the Bay Area Air Quality Management District (BAAQMD), as well as Adventure Cat Sailing Charters and Photon Composites.
