Neat! I thought my husband was the only one with one of these!
He made several of different lengths.
During the last hurricane, we put one of our portable generators in the back of our pickup, and went around to all our relatives houses and friends and neighbours and gave them all about a half hour of 'juice', long enough to bring their fridges back to cold. We had stockpiled lots of gasoline when we heard the storm was coming.
We made sure that we ourselves pulled their mains before we did this, and put them back before we left, as you never know when the power could come back on, and that would be fireworks galore.
We also have a double ended hose, so that when we need water and haven't bothered to hook up our generator, we just hook onto the outdoor faucet of the next door people, as they are on town water. We run the long hose thru the woods. We have a well, though we do have an extra point with a pitcher pump on it.
