the gasifier heats up wood or other material so that it releases its hydrocarbons in an anoxic environment. The laws of physics at least in regards to the GEET engine and "free energy" are fairly straight forward, you can't run a lawnmower or a generator off of water. You can run an engine briefly or poorly on watered down gas. The reason no one is running their car or powering their house with a GEET engine anywhere in the world is that it cannot be done, not as a result of any sort of conspiracy.
Did you read about the plasma waste disposal and how it does not create much if any net energy?
