Open challenge? Not. Sounds like more of a media stunt than a real challenge:
"This offer is not open to any and all persons. Before being considered as an applicant, the person applying must satisfy two conditions: First, he/she must have a media presence, which means having been published, written about, or known to the media in regard to his/her claimed abilities or powers...Several applicants have suffered great personal embarrassment after failing these tests".
"...That said, we offer the JREF million-dollar prize to for example Dave Clark, Editor of the audio review publication Positive Feedback Online, who provided the above rave review. If Mr. Clark should choose to apply for the prize, he would be unlike John Atkinson of Stereophile Magazine see randi.org/jr/121004science.html#11 who made great noises about being ready to snap up the million, then got distracted by things such as gullible readers who accepted his claimed abilities, and backed out. But well see "
