1. Project Overview
As the realization that the earth has finite resources and we must conserve the assets we have left the sustainability movement has come into the mainstream. In the emerging world of sustainability, green products and zero emissions there are many new initiatives that are trying to spearhead efforts to create harmony with the world around us. As those efforts to continue to gain momentum, not only is it hard to look at any new construction project without the consideration of the carbon footprint, but projects are being made to push the very limits of green technology. The Green Island Project is such a venture, a three phase project that aims to create harmony with the world. The first phase of the Green Island project is to design and build a trimaran research vessel with a minimal carbon footprint by using the latest advances in green technology. To accomplish the task of being completely sustainable the Green Island trimaran will utilize drag, wind and solar power generators coupled with hydrogen generators and batteries to achieve a minimal emission footprint. With all the diverse generating equipment the trimaran will be using, a scheme of power electronics is needed to clean, regulate and store the power. This scheme will need to include the ability to take power from multiple generating sources and merge the electrical inputs into a single power supply. To do this a power controller will be used. The controller needs to be able to merge all of the electrical inputs into a single power supply, and monitor those inputs and outputs as well. If there is an unforeseen emergency the controller will need to have an emergency shut-off mechanism as well as a system to provide over current and short-circuit protection. At the end of our design process the controller will need to be robust, consumer ready and easy to use.
