Técnico Solar Boat

With the Project:
Técnico Solar Boat

Técnico Solar Boat is a university project, established by a group of students of Instituto Superior Técnico in Lisbon from different engineering fields. Técnico Solar Boat works on the development of a manned competition vessel powered exclusively by sustainable energies. The aim is to promote renewable energies, sustainability, and electric mobility. Counting two finished solar prototypes, now the third solar-powered boat and the first hydrogen-powered one are being developed.

INITIAL SITUATION

The idea of creating a university project was born out of the desire of a small group of students, who wanted to put into practice the theory learnt in classes and to be a part of the environmental change the world needs. In the beginning, the main goal was to develop a functional solar-powered vessel to compete in the Monaco Solar & Energy Boat Challenge and to learn as much as possible with it. Economic difficulty had been one of the most challenging parts in the past six years, even though there were some improvements.

SOLUTION

Técnico Solar Boat was founded in 2015 by eight Naval Architecture and Ocean Engineering students. The idea of creating a university project to develop a sustainable manned competition vessel was born out of the desire of that small group of students. They at the same time wanted to put into practice the theory learnt in classes and to be a part of the environmental change the world needs. The plan was to construct one prototype per year, interspersing the technologies used. Therefore considering both Hydrogen and solar energy, each vessel would compete and be improved for two years.

INNOVATION

With the solar prototype, the use of a T-shape hydrofoil configuration (a type of underwater wings) allows the boat’s hull to be above the water, with only the struts holding these hydrofoils and the propeller partially submerged. This prototype has a dual-motor system composed of a 1.5 kW motor for cruising speeds and a 5 kW motor for high speeds, the motors can be engaged via a clutch gear system in order to choose the most suitable combination of motors for the current speed.
