Free energy suppression is a conspiracy theory claim that explains why advanced technology that would reshape current energy paradigms is being suppressed by certain special interest groups. These groups are usually claimed to be associated with the oil, coal, nuclear, or natural gas industry, to whom current energy generation technology is profitable, or government agencies who view such as potentially detrimental to the national or world economic system.
In this context, the term “free energy” is not well-defined, and should not be confused with thermodynamic free energy. Generally, it is used to refer to purported transformative technologies which have the potential to dramatically reduce personal energy costs with relatively little capital investment.
There have been numerous free energy claims over the years. Many, such as those implying perpetual motion or those based on extracting zero-point energy, are viewed as impossible according to accepted physical laws. Others, such as cold fusion, while not fundamentally impossible, are not accepted as established by the scientific community. Conspiracy advocates therefore claim that the scientific community has controlled and suppressed research into alternative avenues of energy production via the institutions of peer review.
In addition, some claim that devices capable of extracting significant and usable power from pre-existing energy reservoirs for little or no cost exist but are being suppressed by governments and special interest groups (such as the fossil fuel and nuclear industry), and that suppression has been going on for some time. According to energy suppression conspiracy advocates, the main motive behind this is the preservation of the economic status quo and sustained increase of fuel prices. Variations on the energy suppression conspiracy state that free energy cannot be allowed in a capitalist system because the economic system would break down if it were introduced.
Proponents of this conspiracy theory also claim that certain renewable technologies (such as solar cells and biofuels) and other efficient technologies (as electric vehicles) are being suppressed or weakened by governments and special interest groups.
Free energy research is typically considered to be pseudo-scientific or unrealistic by the scientific community. Conspiracy theorists allege that this is a deliberate attempt by conspirators to suppress this research. There are various other factors which can prevent funding of some alternative energy development, such as “time and information” and capital costs. Groups behind “the conspiracy” have been said to include various national governments, international automakers, and the petroleum industry. An article in Nexus magazine claims
The spread of working free-energy technologies has been prevented by wealthy elite governments, deluded inventors and con men, as well as a non-demanding public.
