This quote by Frank Lloyd Wright is the summary of an article written by Michelle Richards in her post 'A Reluctant Camper' in Unitarian Universalist Parenting.
Our family has camped- mostly in warm weather and sometimes sleeping on top of rocks. I too have experienced the wonder and quiet of the night. Have you?

Answer- the Electrically Challenged Sailboat
This post spoke about the Sherlock Ohms solving the electrical problem of the sailboat.
It is from this Dec 2010 Design News Article written by Bob Humphries.
Here is the answer to the problem on the sailboat:
"During the winter decommissioning I went head-first into a locker to examine the back of the engine and found the ground stud on the engine bell-housing was hot enough to raise a blister on my hand. The engine manufacturer had installed a stainless steel 3/8 x 16 1″ long stud to use as a grounding point for the multiple grounds from the various electrical loads. The stud was threaded into the engine block and a nut was used to tighten the bell-housing, then the ground wires were placed on the protruding stud.
The resistance of this bolt caused a significant voltage drop which severely limited the voltage to the starter. I installed a #00 ground wire direct to the bell-housing next to the starter itself and ran the ground wire to a copper buss bar mounted on a nearby bulkhead and connected all grounds to the buss bar.
The owner removed the boat from the market and enjoyed it for many years. Stainless steel is a wonderful material for fastening in the marine environment and works well for clamping two things together but should never be used as a current carrying component."
