I've been reading about "lifters" for a while now, and I had put off building one because of the inconvenient amount of power needed for it to work. I was wondering if there were a way to power it using a simple ac source (an outlet, maybe), or perhaps something to the effect of a Tesla coil, and I was wondering what modifications in the design would have to take place for it to work properly with either. I wasn't able to find any circumstance in which either of those possibilities have been explored as an alternative to dc. I'm not sure how stupid of a question it is, but any input would be very appreciated. Thanks.
