[rollei_list] Generating Electricity for Camping

With all the discussion about engines and generating electricity, I thought 
I'd ask your advice.  I'd like to go camping separated from civilization, say 
in a canoe.  But, I require the use of medical devices which require 
electricity.  One is a pneuma press to squeeze fluids out of me, and the other 
is a 
breathing apparatus to let me breathe while sleeping.  A deep cycle 12 volt 
battery with an inverter would probably suffice to provide the power, if I can 
keep 
it charged.  I've thought about photoelectric cells, but that doesn't seem 
reliable enough to me.  A gas or diesel generator might work, but weight would 
certainly be an issue.  A German company has recently put a fuel cell 
technology 
on the market at a ridiculous price ($5,000 US) for a person like me.  So, 
how would you solve this problem?  Thanks.
