This is the key in future telecommunication , weather modification , and power efficiency

Given how awful the result has been for commercial switchers in terms of EMI, I would think that the power levels involved here would pose a much greater challenge. At least theoretically, the design of appropriate shielding and filtering could contain the problem, but I have to think that the added cost/size/weight increase would push manufacturers away from this approach if it was a regulatory requirement. And without those requirements, I can imagine all HF applications (and possibly beyond) will be severely damaged. My area, medical ultrasound imaging/Doppler, typically operates in the 2 to 15 MHz region and looks at signals as low as 100 nV or so. If a hospital was fed by one of these in which the EMI problems were ignored or poorly dealt with, I doubt that our shielding efforts would be successful enough to avoid missing certain pathologies.

Conventional Transformers eliminate harmonics upto some extent, through shielding and isolation. Won't the semiconductors used in SSTs in add the harmonics instead of reducing those?
