| Abstract |
90% of products trade are done across the seas, being the 5th largest pollutingsource worldwide. What is the energy scheme of a boat, how is this energy used and what are the domains to be improved. We will follow the energy stream, fromstorage to electrical energy and then to kinetic energy. Besides, we will describe thebenefits resulting from top level competition like the America's Cup, in particular toolsdeveloped allowing to have flying boats, but as well enabling efficiency gain of up to50\% for some other boats. |
