I would always want to see something cool and unique at these events, but you have to be reasonable. Not all people are going to be as enthusiastic as you with your new creation. I am pretty sure the hovercraft cart would be blowing dirt, dust and little metal chips into the breathing air of teams near the floor working on their robots. There is leakage around the skirt to consider. Use it for technical education, fund-raising, and FUN !
