Wow, a service station so 3 cabs can run 24/7!. If that is something to brag about because its difficult then welcome to the real world where we have slightly more than 3 cars. Main issue is the high cost of batteries. You could imagine swapping old worn-down batteries for practically new ones. I wonder how to solve that. Next step is standardising on a small number of batteries. If I see how many different tires are on offer I hops that will be solved as well.

Pie in the sky or a money pit. The only way there will be even 1 percent battery vehicle ownership in the U.S. in 10 years is if the federal governement forces us to buy them. Period. Mr. Wolf and his Better Fantasy are the latest in a long line of schemers and scammers who try to persuade people to follow them down the road to the impossible.

The battery-swap idea makes sense for a taxi company that has a regular schedule and can predict when and where they will need to swap batteries. It seems far-fetched that such a system can meet the needs of the general public. Batteries are very expensive, and it is not practical to have stacks of them waiting for customers that may not show up.

Will EVs happen this time? What do you think?

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.
