For a couple of years, maybe. Try buying 2 phase power from the power company now. I know 2 phase power can be created with a Scott-T so you will have to buy 3 phase power first and then spend more money to create the Scott-T. What will that get you other than loss of money? > You didn't even know what a Scott-T was. Turn in your degree now. > An ass-umption of yours, dip-shit. Turn in your brain now. It has little to offer.
