Yes, perpetual motion, separating momentum and weight, and it's so
nice to just use the word 'weight' and not millions of formulas.

The onbly problem: The theory says: extracting weight from an object
with momentum that carries dark matter slows the object.

This means that if millions of companies turn to this idea, Earth
may slow in it's path and plunge into the Sun.

Deriving energy from the separation of momentum and weight in
small amount does nothing, but otherwise over the hundreds of
years, the slightest slowing of Earth may turn it's course around
the Sun to a plunge course, and there is no reverse known science
that would alter Earth's course in the opposite effect.

In a way this may be like Global Warming. There may be no
solution to Global Cooling.
