I've had the same bad luck with solar! Let me know if you find anything that actually works!

As a workout guy I don't go far without a box of protein bars. As a survival guy I don't go far without my FAK, PSK, EDC, etc. The diet wouldn't be fun, I have light, the only real danger would be dehydration and passenger stupidity.

I've actually been in a similar situation on a cruise that lost one engine and had to hobble back over three days. We had power, food and entertainment but you'd have thought the ship was going down the way most passengers complained and vandalized the heck out of the ship.
