My idea is to have ICE+ generator rental trailers (probably one wheel) When leaving town with your electric only you just stop at EEHaul and pick up a rental mileage extender.

Is perfect compromise an oxymoron? Let's face it, if you have the money to spend $35K on a compact car, you're doing it for your emotions not your pocketbook. I've driven a 2005 VW Jetta (gasoline) over 130K miles for less than $13K in fuel costs. Add that to my purchase price of $15.5K out the door, taxes, title and tags and I'm still $7K ahead of a Volt with ZERO miles driven. This doesn't make any cents. Someday, it might. For right now, the sales figures for EV's speak volumes.

Let's face it, the Chevy Volt is nearly a perfect compromise. I have a coworker that has a 20 mile each way commute. If he has to go visit customers, he charges at work so that he can make it home with no gas. Otherwise, his overnight charge is sufficient. If he decides to drive to LA, he can on a tank of gas the car takes regular gas. He's used 12 gallons of gas and driven 11K miles so far. The PGE hookup is dedicated and he pays less than a nickel/kw-hr. He is in an income bracket where he can afford the $35K price tag. He swapped this for his Mercedes and loves it.

LATEST ARCHIVED BROADCAST
As data rates begin to move beyond 25 Gbps channels, new problems arise. Getting to 50 Gbps channels might not be possible with the traditional NRZ (2-level) signaling. PAM4 lets data rates double with only a small increase in channel bandwidth by sending two bits per symbol. But, it brings new measurement and analysis problems. Signal integrity sage Ransom Stephens will explain how PAM4 differs from NRZ and what to expect in design, measurement, and signal analysis.
