# It works with water
the gravitational engine is a very good idea to generate electric power, and not rely on energy systems such as oil or generation systems to maintain very difficult energies such as wind power or solar panels are very expensive.
other types of free energy such as radiant energy, magnetic motors use ferrite magnets, neodymium magnet, copper wires Also use engines, or aluminum materials.
This is an experiment of free energy, gravitational engines work with the energy of gravity of the
