Simple Steam System Helps Boost Power, Mileage
George Zimmerman uses heat from the exhaust pipe on his 350 Ford Dually to generate steam that helps power the truck. A 3/8-in. steel tube runs from a small water tank up the length of the truck’s vertical exhaust stack and then back down. As the water turns to steam, it is pulled through the tube and into the air intake between the air cleaner and the throttle. It’s cheap. It’s easy. And the added power is noticeable.
  “The truck runs much better than it did when I first got it and hadn’t installed the system,” says Zimmerman, who warns that the modification is not for every vehicle.
  “You need a big strong engine and the right design,” he says. “The steam is delivering oxygen and hydrogen into the cylinder, and it can be too powerful for a light engine.”
  Zimmerman knows this from personal experience. The first steam power system he made went onto on a small Toyota 4-cylinder car. He immediately noticed a reduction in fuel used with no reduction in power. However, the good times didn’t last.
  “I was flying down the road when I heard a noise,” says Zimmerman. “Smoke poured out of the engine as I pulled over.”
  A connecting rod had blown through the engine block. Zimmerman suspects the motor couldn’t handle the hydrogen being fed into it.
  In his next design, Zimmerman went to the 1-ton truck with the vertical exhaust stack. The water tank is even with the entry point of the pipe into the stack so there’s no water pressure forcing water and steam through the system.
  “The steam is pulled into the air intake by the vacuum,” he says.
  As the engine is accelerating, more heat is moving through the stack, producing more steam. At the same time, more vacuum pulls the increased steam through.
  Zimmerman believes the system would work even better on a diesel engine. He also is positive the system can be perfected beyond what he has done. However, at the age of 80, he doesn’t feel he can do it.
  “I’ve not tried to patent it, in part because I would like others to develop it and use it,” he says. “I think if the trucking companies perfected it, it could really set the oil companies back on their heels.”

Editors note: George Zimmerman died before this story could be published. It is a concept he worked on for more than 30 years, blowing several engines in the process. George wanted to pass on the concept to FARM SHOW readers in hopes that someone will carry on his work. His son George Jr.’s contact information is at the end of the story. Feel free to contact him with questions and he’ll try to help.
