If i came out and described this particular item, it would be "stolen" by a major consumer goods maker and be impossible for someone in this NG to make a reasonable profit if they tried this.
First the potential designer must be well-grounded in switching circuitry and in non-linear loading effects.
Second, if you do design this item for commercial sales, you must be willing to pursue the marketing etc OR know someone able to take on that burden.
The item is medium power,about a kilowatt runs of mains power, and generates about 1KV.
You will be battling the majors: GE, Sharp, Kenmore, etc.
If seriously interested, send me an e-mail and i will disclose the concept; your cost will be your time, no$$.
