Their challenge was to determine the power available from the waves in the Charles River, design and construct a device to produce electricity from wave power, and then determine the efficiency of their device. The class, taught by Dr. Tom Consi and Dr. Franz Hover, was composed of six OE juniors: Kate Baker, Jeremy Chambers, Matt Greytak, Johanna Mathieu, Brian Mueller, and Katie Wasserman.

During the first half of the course the class built their own wave probes and successfully measured wave heights in the Charles over a period of 15 hours. They then calculated the significant wave heights and peak frequencies in order to calculate the energy in the river. Next they did research to determine what sorts of wave energy conversion devices have already been developed, the advantages and disadvantages to these devices, and their applicability for use in the Charles River. Many previous attempts at producing sustainable energy from waves were abandoned in the late 70s because of low efficiency and lack of funding. However, today, with new technologies, lower cost parts, and the ever-growing need for alternative energy sources this field of research is particularly important for us to jump back into. The class decided to design and construct a free oscillating water column, a The wave probe experiment. hollow cylinder that oscillates at resonance with the waves causing the chamber of air within the cylinder to continuously compress and decompress, producing pneumatic energy. This energy is used to drive one or more turbines, which convert mechanical energy to electrical energy. A system of valves allows the air to flow in the correct direction through the turbines. The class has designed the hull of their oscillating water column and run a series of dynamic models to determine how it might behave in water. They have also researched turbines and different methods for energy extraction including piezoelectric materials and linear generators. Their design includes catenary moorings, drawing from offshore platform design experience. Also, they have developed a system of electronics and sensors that will allow them to monitor the motion of their structure, the energy it is generating, and its efficiency. They are looking forward to beginning the construction of their device in September. Hopefully, the device this year’s 13.017 class designed will not only work but also allow efficient conversion of wave energy into electricity. If this does happen it can become a prototype for the next generation of small-scale sustainable energy solutions.

Wasserman and Meg Brogan) have been working on the International Student Offshore Design Competition (ISODC) with Professor Triantafyllou. The ISODC is a SNAME and ASME sponsored design competition with the goal of encouraging interest in offshore engineering. Students (teams of up to 6 people) design an offshore “structure,” such as a Tension Leg Platform (TLP), spar buoy, FPSO, etc, and create an extensive web page demonstrating their design. The design must encompass five fundamental areas of offshore engineering, and three more technical areas such as the detailed mooring characteristics of the system, tendon behavior, and/or detailed structural analyses. If the design places high enough in the competition, the team will be invited to present at the SNAME annual meeting. Unfortunately, since this is the first year that any MIT undergraduate students have participated in the competition and since the MIT team has only two members, compared to the six members that most teams have, expectations aren’t too high.

Meg and Katie have completed the basic weight, balance, hydrostatic and hydrodynamic design of a TLP. The TLP is modeled after Brutus, a Shell owned vessel operating in approximately 3,000 ft of water in the Green Canyon Block of the Gulf of Mexico.

scale model of a Flettner rotorship. The ultimate goal of this project was to create a teaching tool to illustrate the Magnus effect and its application to ship design.

The Magnus effect creates lift much like a curve ball in baseball. Basically the rotating ball creates a vortex around the center, which, coupled with the wind flowing around the cylinder or ball, creates a pressure differential. This pressure difference causes a lift force that becomes the thrust used to move the vessel. Flettner calculated that the rotors needed to be 1/10 the size of the original sail to produce an equivalent amount of thrust. Based on this design principal, and a combination of theoretical and experimental Magnus effect data, I wrote a program that would allow you to input wind speed, rotor size, and rotor speed and would output the predicted speed of the boat.

ell us about your academic accomplishments. ou mean besides managing to not being kicked out of ycare? Seriously, I have a MS in Mechanical and

erospace Engineering from University of Virginia and a MS Naval Architecture and Marine Engineering for MIT. I do t have a BS, although I finished four years in the

erospace Engineering Dept at the Polytechnic of Milan in ly. I am currently working on my Doctorate.

hat topic are you doing your thesis on? am writing a free-surface flow simulation program to lculate the total resistance for surface piercing vessels, in rticular I am interested in sailing yachts.

ow did you end up in UVA? MIT? ell, it's kind of a complicated story. During my fourth year Milan I realized I wanted to spend a year abroad studying. Europe there is a student exchange program called rasmus" that allows students to go to a different university r a year, take courses there, and then easily transfer the edits back to your school. I was considering going to the oyal Institute of Technology in Sweden, when I was oposed a new exchange program between some uropean and some American engineering schools. I cided to try it and the three alternatives in the US were:

niversity of Virginia, Oklahoma State University, and Texas &M. The choice was made simply looking at a map and alizing that UVA was the only one close to the mountains, e ocean, and some big cities like Washington DC. nfortunately when I arrived at UVA, I quickly discovered at, because of big differences between the US and Italian llege systems, the exchange program, as planned, would ve not worked. However, before I had to make the cision of going home, I was asked to stay at UVA as a aduate student even though I didn't have a bachelor’s gree, because I had completed four years in Milan. So I cided to stay and planned to go back to Italy after two ars instead of nine months. But it didn't exactly work that

ay, because after my first year in Virginia, a couple of ofessors asked me to stay for a Ph.D. At that moment, I cided that if I was going to stay in the US for a doctorate it d to be in what I was interested, which is sailing yacht sign. After some research, I found Prof. Milgram in this partment, so I came to Boston to talk to him. I then applied MIT and got in.

hat's been your most memorable social experience at IT? nswer for Faculty to read: I don't have time for social life as l my time is dedicated to research. For everybody else: I n't think I can single out one single memory, but just few ys ago a good friend of mine that started at MIT almost at

een your most memorable educational e at MIT? say, and some might think this is cheesy, the

Boston life differ from Italian life? en ask me this question and I find that is not easy answer it. The biggest difference, which is also ifficult to make a comparison, is that when I was as living with my family and commuting to school while here I live alone. Socially things are not ent, as I go out with friends here as I did back in be what we do is somewhat different (there's lot more drinking involved here). And I try to go ing, in the winter, and sailing, in the summer, as

can, even though at least for snowboarding, I'm he same level as I did back in Italy because there heaper. Also comparing the educational part, in o research only when you start working on you and before then it is only course work, while

nd most of my time on research.

finish with your PhD, what do you want to

ke to stay at MIT after graduation and keep my program beyond what I need to do for my -10 years I would like to be working as a yacht nd be living somewhere other than Boston, like

Coast or maybe even Australia or New Zealand, se I don't like Boston, but because I found that I to live in different places and have different s.
