There are only 4 fundamental forces in nature: gravity, the elecromagnetic force, the strong nuclear force, the weak nuclear force. Only the electromagnetic force is significantly controlled by humankind--its action and strength is of our dimensions. It underlies all chemistry, all biology, all light, all radio/internet communications, and all life. It is wildly improbable that another force, e.g. spiritual, god, 'mental', is yet undiscovered by the thousands of laboratories, scientists who work every day, none finding a reproducible effect previously unknown.
Gravity is only important when there are big chunks of mass, otherwise of no consequence for human life. The strong and weak nuclear forces are good for keeping atomic nuclei together, and we humans need atoms. They do neat things in stars, like our sun, too.
'Cold fusion' does not exist. "Never attribute to malice what may be due to simple incompetence". Or, in the case of cold fusion, simple greed and self delusion.
Lest anyone claim that the weak nuclear force is the secret 'sauce', let them show how it works with electron neutrinos, tau neutrinos, and muon neutrinos!
Anyone can get 100 Billion neutrinos in the palm of your hand--just hold it out--this many or more pass through planet Earth every second. None have produced cold fusion, nor even hot fusion on Earth.
