What an excellent idea, Jana. I can imagine that even the best swimmer could really use some help in an emergency situation - so a life jacket that could swim for you would be amazing. How do you think it would work? I can see you have fans in there for wind power, how else would they be powered? How great would it be too if the jacket could identify the closest way to get to shore or a boat? Really great inventing - I wonder what else you will come up with!!!
