Building Knowledge Base
If we learn enough and organize the information well enough it becomes easier to solve the problems we need to solve. If we work together and share knowledge and build up knowledge in other seasteaders it will help us make real progress and increase our chances of success. If we don't write up things then different people will keep reinventing the wheel and keep going down dead ends that have already been explored by others. We should never be working in secret.
We can do research on the net, experiments with models, and write up what we learn in the wiki.
When we get as far as having a fully trusted design that is affordable, safe, economical, then building it is easy. So the knowledge is the main problem.
