Ephemerisle2009
Ephemerisle will be a gathering on the water of people interested in seasteading. The first gathering will be inside the San Fransisco Bay. Future years might be outside the bay or further out in the ocean.
One proposal is to have an Ephemerisle Contest between seastead models. These models would be large enough to play on, like WaterWalker2. There might be constraints like requiring that the model can be transported by a single pickup truck. Prizes might be in the $1,000 to $5,000 range.
