Mr. Jarvis: You told all the problems with BATTERY TECH. yOU WANT national energy policy. Could you please specify it with solutions rather than magnifying the problesm? Need solutions for the problem, not problem to the problem.

Hi Brian -- Max here -- I certainly hope you are going to stop by my stomping ground here in Huntsville when you are on the Alabama part of your trek. First of all Huntsville is an oasis of high technology ("more rocket scientists per square foot than anywhere else in the world," or so I've been told). But more importantly I'm here and I'm sure that you owe me a beer :-)

Duane, maybe Oregon can figure a way to transmit some to Germany. Sounds like they'll be needed it soon. ; )

But Ed, we're poised to build all those nuclear power plants all over the country... problems solved! Oh. Wait. Never mind.

The Pacific Northwest would likely be a better fit for electric or plug-in hybrid cars. We have mild weather so heater and AC won't get over worked. Most commutes are on the order of 25 miles or less each way. We also have too much electricity because of all of the wind farms being built in central Oregon. The turbines are government subsidized and proliferating like wildfire. There isn't enough transmission capacity to get the power down to California where it's needed more, so when the rivers are up, the wind turbines often have to shut down to allow the hydro generating capacity to regulate the rivers. Too much green electricity... Go figure.

The bait-and-switch car. I was promised an electric with great range, what I got was a hybrid. How do I sell my stock in GM that my government purchased for me?

My Jetta diesel gets better mileage,is cheaper,has heated leather seats and when I burn bio-diesel (most of the time) I have ZERO net co2 emissions.

Let's see... we burn coal or natural gas, or deal with nuclear waste, in order to boil water to make steam, to turn a turbine, to produce electricity, which is distributed through lossy conductors, and stored in a battery, with some efficiency. To make the battery, we mine lithium and nickel, and other heavy metals, using fuel to extract them. And we transport them using fuel to a site where they are fabricated using fuel into the form of a battery. From whence they are further transported using fuel, to the place where cars are assembled. THEN they are further transported using fuel, to the place where cars are sold, in order that we might enjoy being able to move about the planet ... efficiently? At $.20/kwh, given all of the inefficiencies in this system... which is less expensive, electricity or gasoline? OH...I forgot the cost of extracting and transporting that coal, too. Which is why natural gas is the favored fuel for 'peaking plants' in the electric industry. And PV solar electric is not the answer. It costs 4-5 times as much as fossil generated electric, and that's WITH government subsidies. Without, it's much higher. We need a national energy policy based on life cycle environmental impact and costing, and not on political polls.

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.
