Here's some fodder for comment:
SeaKettle Life RaftInteresting concept, but I see some drawbacks.
- requiring the sun to make it work.
- a RO desalinator would cost less than the additional costs for the special construction needed to make the life raft.
- the designer's understanding on inflatable chambers in coated fabric is in error as you wouldn't see those flat surfaces unless drop-stitch fabric is used, which would really jack of the cost.
Cheers,
