We are getting ready to sell all our appliances and house and we want to upgrade to low wattage household appliances. We will be moving into a smaller house I have designed that will be heated and cooled by the natural forces of wind, earth, water and fire solar, in a new design I've created. Our system is 120vac square wave 15,000-30,000 watts and 12vdc. With power generated by wind,solar,hydrogen-water, that just leaves earth hmm I'll get to work on that. Wow think about it water=hydrogen, air=wind, fire=solar, and earth=cold-hot energy. Back to the post:) If you have upgraded to lower watts please let me know. If you have had problems with a lower watt upgrade please let me know. Knowledge is key. Thank You!!!
