Several of Evans's central claims were later shown to be mathematically incorrect[7][8][9][10] and, in 2008, the new editor of Foundations of Physics, Nobel laureate Gerard 't Hooft, published an editorial note effectively retracting the journal's support for the hypothesis.
[14] In July 2017, Evans claimed (on his blog): "There is immediate international interest in [papers] UFT382 and UFT383, describing the new energy from spacetime (ES) circuits.
In November 2017, Evans expanded on this point as follows (again on his blog): "There is no reasonable doubt that the vacuum (or aether or spacetime) contains a source of inexhaustible, safe and clean energy.
He concluded that activities in the subject "have remained limited to personal web pages and are absent from the standard electronic archives, while no reference to ECE theory can be spotted in any of the peer reviewed scientific journals".
[7][8][9][10] In response to these demonstrations, 't Hooft's editorial note concludes, "Taking into account the findings of Bruhn, Hehl and Obukhhov, the discussion of ECE theory in the journal Foundations of Physics will be concluded herewith unless very good arguments are presented to resume the matter.
