I'm pretty sure there is a difference of energy involved from emerging a glass parallelepiped,depending witch face is down, from a tank of mercury due to adhesion force. Cause there is a different border area on witch adehesion force act on. If we have a 100x10x1 cm glass body,we have that if we emerge from wide border,10x1+10x1+100x1+100x1 (220cm2 border) and from thin border 100x1+100x1+10x100+10x100 (2200cm2 border). A difference of 10 times. Cause little force involved probably nobody thought about it. What are your comments? Can we use this difference to sink and submerge a glass parallelepiped to gain energy? Thanks for comments

you mean to insert the object in one orientation, than turn it , and than extract in another orientation?

Yes
