Some things I might get around to doing sometime:

Structure Modeling
I would like to do a wiki page on structure scaling issues as you scale up a model. Several different people have said they don't think my models scale up. I am sure they do. However, seasteaders really need a wiki page with general rules for structure modeling and scaling structure from models to prototypes. My grandfather was a civil engineer and told me some of the rules when I was like 12, but in 1 hour of searching with google I have not found the kinds of simple rules he talked about. Things like, "if you make a horizontal beam twice as thick top to bottom then it can carry 4 times the weight". If anyone knows of a URL or the right keywords to find such, please let me know. It seems like it should be "structure modeling" or "scaling rules" or something, but I have not found what I am looking for yet.
Note that this is a different issue from modeling wave action on a model. This is looking at things like when will a beam break and how different would it be in a full scale version from a model.
Measure Accelerations
I have a "G Data Logger" and have not used it on either models or a real boat yet. Could be good to quantify the accelerations so can compare to written sources for what Gs bother people.
Measure force to move models
Measure force needed to move models at 1/5 MPH and 2/5 MPH to simulate 1 and 2 MPH. Also thinking of measuring force to move one of the barrels for the 1/5th scale model to be able to estimate how fast a kite will make that model move.
Test tiling idea for WaterWalker
I could build several WaterWalkers and try connecting them together to verify the tiling plan. I ordered some extra foam balls and made a second WaterWalkers but kids played with the balls first and now they soak up water too fast. So have not done this yet. Need to order more balls again or paint the outside so they are water resistant again.
