I had a glance at the site for Powerwatch, a small alternative organisation with an interest in health risks of EM fields, and found its credibility somewhat reduced by its recommendation of Vortical Dynamics, a company offering various twisty copper devices, "containing specially imploded water", with claimed energy effects (see the Centre for Implosion Research).
Vortical law states the foci owes its existence to the masses surrounding it; take away the two masses and their foci disappears, therefore the foci does not have its own gravity, it is in essence “borrowing” its existence from the masses rotating about it.
Vortical says: So what happens with VC titles you have already purchased?
