I basically understand wiring sizes and resistance...being a plumber and all lol...but what I was trying to say...and thank for helping me to clarify my thinking...is that there should be more research into making products that use the lower voltages supplied by alternative energy systems. Using your example Xringer, why can't somebody make a 12vdc HDTV that uses less than 400w. (if you are trying to save money, why even buy an HDTV
) Everybody wants to be comfortable, everybody wants to save money. Maybe the definition of comfortable needs to change a little.
Its like the refridgerator. It used to be the biggest energy hog in the house. Now they make ones that use as much power as a 75w light bulb. As the energy supply changes the appliances that use that energy need to change too.
