ClearCut Surgical
An electrocautery pen that suctions blood and smoke at the touch of a button.
Omnidirectional Lobster Trap ("omni pot")
A more efficient lobster trap design that enables lobsters to enter from and be trapped in all directions.
LITTORAL COLLECTION MODULE (LCM)
Low-cost, rapidly scalable sargassum collection device retrofits onto any small boat and allows collection of sargassum before it makes landfall. Local fishermen can participate in cleanup, services can be extended beyond tourism to civilian beaches, and avoiding sand-contamination allows many types of valorization of collected sargassum. This device matches the collection capacity of larger conveyor-based collection barges (at a fraction of the cost and lead-time) and has a flat marginal cost of <$1/m3, allowing cleaning all day (cleaner beaches!).
Underslinging
An excavation-free method for replacing failing building foundations (alternative to needle-beam underpinning and cut-and-post underpinning).
SuperBlocking
A method for automated container lashing aboard container ships.
Cable Train
A train that manufactures HVDC cable in-situ.

Mechanical Radiotherapy Phantom
Precision mechanical device for QA of radiotherapy treatment plans.

Macroalgae Raceway
An apparatus for adapting existing microalgae raceways for growing macroalgae, such as gracilaria.

energy deficit associated w/ lane # in track & field
Project attempted to quantify the energy deficit associated with lane assignment in the 200m and 400m events in Track and Field. There has yet to be a sufficiently technical study, which measures the physical effects of lane assignment at appreciable speeds. The goal of this project was to determine the relationship between the curvature of different lanes and the force and body lean required to maintain running speed. The results of this project show that at a speed of 9.0 m/s the body lean and average force application of the subject varied by 6.34° and 76.3 N, respectively, from Lane 1 to 6, and this difference is positively correlated with running speed. These results call for further investigation and consideration of systemic changes to the sport of Track and Field.
