I appreciate the inefficiencies... I'm well aware of them. This is not some idea to change the world or invent some great new product. Its a project because I like building stuff and seeing what I can accomplish. On paper is it less efficient? Yes. Is it a different idea that seems like it would be fun to build? To me, it does. I'm glad you enjoy thinking in your box, I hope you found a good interior decorator to make it nice and comfortable. Personally I like screwing around with stupid ideas and trying to see if there is something someone missed. Its the building process that's fun for me, not necessarily the outcome. I don't expect much, but I don't see the harm in trying. If nothing else I get to learn about electrical systems and expand my horizons. Something you should try sometime.
