3. there is a primitive experiment, appearing to show evidence for this, though inconclusively.

read of it in a book by a western author - Martin Caidin; an in-your face guy -- but pretty decent, under the gruff exterior. he had a talk show - where he would confront right-wing fanatics in debate. he appeared on episodes of the "6 million $ man"; and wrote a number of military histories & sci-fi novels.

the experiment is conducted with psi-wheels. it appears to show a form of very low level energy flowing between the palms of one's hands.
but, the results could also be caused by very minute fluctuations in the air flow; up-drafts & down-drafts caused by hot & cold air rising or falling, air conditioning, etc.. so the results are not definitive. James Randi of CSICOP, challenged Caidin to demonstrate the psi-wheels under radically controlled conditions -- but Caidin is said to have avoided the challenge; though Caidin had a different take on the matter.
