I've been in power supplies and lighting electronics my whole career. And, I might be jaded about this to the extent that my practicality and experience outweighs my imagination. I think not though. This sounds to me like someone at a big corporation that is making up this stuff in a complete vacuum. I could be wrong; however, that is how it appears to me.
Thanks. I appreciate your response. I'm sure you not jaded. I was just testing your resolve (and also fishing for more information.). That's what I like our readers...you call out the impossible or, at least the improbable.
I have a several year old emergency Cobra Power Inverter that produces 1.5 KW continuous and 3 KW peak for $150. It is 2.5" x 9" x 8" = 180 cubic inches. My ordinary laptop is 0.75" x 13" x 10" = 98 cubic inches. It seems like we were close already with a higher power unit. [I'm not sure where the 40 cubic inch laptop came from, is it a netbook?]
