What can provide power to a travel trailer while reusing its own power?

I need to know if there's a way to hook something up that will power a travel trailer while reusing its own energy to power itself.What can provide power to a travel trailer while reusing its own power?
In talking about "powering" a travel trailer, I am assuming you mean electricity. Electrical power is needed most by travel trailers, as they are pulled from place to place by a vehicle.



There is an entire industry that makes generators of electricity. Some generate 12 volt power for boats, cars, %26amp; trailers. Others generate 110 volt house-hold like energy to operate the house-hold like stuff on these "toys". Generators are engines that usually run on gas and are put in closets and other out-of-the-way places on the travel trailer. They can run on propane, diesel or natural gas, but good old gasoline is the most common.



Many of the generators are started by a battery connected to the generator. In order to make sure they will always start, they charge their own battery. So they do (in a way) power themselves.



Now if you're asking if they can make their own fuel source, and then deliver that fuel to another vehicle: That's the HOLY GRAIL of engineering. The perpetual motion machine if you will.



To date nothing we have in our technology can do that!!
