Thanks, John.

I'm not familiar with the gel nor its heat absorbing characteristics--whether 
the heat capacity is much greater than that of water. If it is not, then 
there is no point. But remember that the mass of a body plus ballast provides 
substantial thermal inertia, and with good insulation temperature fluctuations 
should be manageable.

There are many possible alternatives, but they all cost money. One of the 

lessons, again, especially for young people, is that your funding should leave a
good margin for error--$100,000 of life insurance recommended.
