I am sure that there are a lot of members here who never look in the Gavity Devices section of the forum. believing that only the real whackos imagine that gravity could be used for free energy. Well, now is the time to review that opinion. There are two promising threads in that area: Mikovic and Jhula. In the Mikovic thread there appears to be an imbalance of forces and a number of members are doing their best to close the loop. Jhula's loop is already closed and the system appears to accelerate exponentially. I thought to add a pointer here for anyone who never visits that area of the forum. Please do not reply to this topic here, rather, reply in the Jhula thread.
Even if your bent is electronic or magnetic it is still worth examining Jhula since the principle could be modeled electronically using two oscillators and a magnetic field. Successfully doing so will produce solid-state overunity.
