        Thanks Marcia! 
        
          
        
        And thanks to everyone 
        for all your hard work. 
        
          
        
        I'm still working hard 
        on the thermodynamics of overunity systems, and it keeps getting a bit 
        more difficult.  We recently found a flaw with respect to EM systems in 
        the first law as well. Just makes the present first law a special case 
        (although still applies to a very wide area of systems), and some types 
        of EM systems and interactions do not necessarily obey the hidden 
        assumption in the present statement that a change in internal energy (in 
        this case, in an external parameter) is work.  If only the potential 
        (and thus potential energy) of an EM system is changed, it does not 
        require work or result in any. That's the gauge freedom principle.  The 
        reason for the difference is that all mechanical systems etc. have to 
        deal with Newton's third law opposition to changing the mechanical 
        energy, etc.  So to change the internal mechanical energy, one has to do 
        work.  However, in EM linear systems the field-to-field and 
        potential-to-potential interactions do not have any Newtonian third law 
        opposition.  So one can change the potentials only, without having to do 
        any work to overcome Newton's third law reaction, because it doesn't 
        occur. 
        
          
        
        So I'm working on a 
        way to express that correctly, keeping the equations very very simple. 
        
          
        
        Best wishes,
