LOL, not even close. Autotransformers are frequently used for off-grid systems, a 5kVA unit weighs about 30 lbs and costs $300-$500 new. https://www.solar-electric.com/solaredge-seauto-tx-5000-auto-tranformer.html They are also used frequently (or were) by GIs stationed in Europe so you can run 120V vaccumms, etc. on the 240V power there. I have a 5kv unit kicking around here somewhere that I bought when I was stationed in England or Germany, I think I paid $25 for it(used), but that was back in the '80s. _______________________________________________ UNSUBSCRIBE: http://www.evdl.org/help/index.html#usub ARCHIVE: http://www.evdl.org/archive/index.html INFO: http://lists.evdl.org/listinfo.cgi/ev-evdl.org Please discuss EV drag racing at NEDRA (http://groups.yahoo.com/group/NEDRA)
