Vortex – how are Boeing planning to pressurise the aircraft without bleeds? Ram air? Separate compressors? If so, driven by what?

I don’t quite remember how, but their HVAC is going to be all electric. This is claimed possible by using the currently available power electronic components with high efficiency and light weight. He also said that the 7E7 name was supposed to be interim and for some minor reasons they used it insteadof the typical 7×7, but it stayed because it resonated with the clients. They don’t know why, but people start to put all sort of names for the “E”, efficiency, enhanced, economy,…..i forgot what the original E stand for but it wasn’t an exciting word and Boeing didn’t insist it to retain that meaning according to this guy (at least when they are selling the aircraft). Another thing, the cabin will be pressurized to a higher pressure than today’s aircraft.
