The latest in a series I call, "places I've seen videos of, and my sister has visited." Averaged together, we travel quite a lot compared to the average person.

Here's an update of what was called last year as "One of the most important charts about the economy this century.” Price Changes of selected consumer goods and services over the last ~20 years. It made the rounds at the Fed last year. @ritholtz @slangwise @AEI @MichaelRStrain pic.twitter.com/pt8UEJSIL5— Mark J. Perry (@Mark_J_Perry) January 11, 2019
Perhaps Medoff's most consequential discovery is how to extract the plant sugars and convert them into to environmentally-friendly biofuels: ethanol, gasoline and jet fuel. Lesley Stahl: And I'm told that you call this thing a still. Marshall Medoff: It is a still. Lesley Stahl: It is a still? Marshall Medoff: It's actually making alcohol right now. Alcohol that you can drink, or you can put in your car, or you can do both. Marshall Medoff: Here we are, on the road again. Lesley Stahl: So Marshall, I am driving a huge truck on biomass fuel. It doesn't feel any different than normal gas to me. Marshall Medoff: No. It wouldn't. No. Medoff's ethanol is much better than regular corn ethanol in terms of greenhouse gas emissions - 77 percent better, according to a study that was independently reviewed.This is definitely worth watching. I have no idea if this can be scaled up, but it would seem to be more promising than previous efforts. Of course, there was no information about how much biomass would have to be harvested in order to produce 30% of petroleum used in the country, but it takes 30 to 40 million acres of corn to produce 10% of the gasoline we consume. I'd probably still take the side saying this won't work out.

Altogether, 109 miles of subway-size tunnel lie beneath Chicago and its suburbs, covering more miles than the L, culminating in three suburban reservoirs (not the kind you drink from)...The gist of the project is that many of Chicago's sewers handle both sewage and stormwater. When the city would get almost any rain, the sewers would be overwhelmed, basements would be flooded with sewage, and untreated waste would be dumped in the rivers. So the city came up with this crazy project to build giant tunnels a couple hundred feet underground to divert the excess flow to giant reservoirs to hold it until it could be pumped through the treatment plant, where it would be treated and released. Obviously, the cost of such a program is astronomical. On top of the cost, the changing climate has been a game-changer:
Fitzpatrick drives me to McCook Reservoir, the mammoth holding pen, opened in late 2017, for the tunnels that run beneath the Chicago and Des Plaines rivers. We stand on the edge of a pit that can hold 3.5 billion gallons of wastewater, enough to fill the Empire State Building and then some. It doesn’t smell terrible, thanks to floating aerators and because the pool has dwindled to 30 feet deep—Friday’s leftovers from a half-inch of rain on Tuesday. At the far end we can see the circular tunnel mouth leading downtown. The city’s wastewater netherworld has its own Chicago-centric measurement system. Lake Michigan is elevation 0. The pumping-station control room, on a little hillock, is +25, or 25 feet above the lake. The roaring motors that empty McCook after the rain sit at -297, 30 stories below ground.Behind us, the second section of McCook—which will more than double the holding capacity of the Mainstream Tunnel—is being excavated by gigantic mining trucks. Vulcan Materials, the country’s largest vendor of crushed rock, is digging millions of cubic yards of limestone out of the ground.
“The large and costly deep tunnel-reservoir system in Chicago is not adequate” to handle 50-year storms, Changnon wrote of the impacts from a September 2008 storm that caused the evacuation of more than 10,000 homes in the region. The Chicago Tribune reported that in the four years after the tunnels were completed in 2006, the MWRD released nearly 19 billion gallons of stormwater into Lake Michigan compared to 12 billion gallons in the preceding 22 years. Similarly, there have been 24 incidents of sewer overflow in the lake since the first tunnel came online in 1985, compared to about 21 in the previous 40 years. Then, in February 2018, after McCook had opened, tripling the capacity of the main tunnel, a big rainstorm filled the new 3.5 billion-gallon reservoir and sent another 3.8 billion gallons of sewage into local waterways....By the time I visited in November, McCook Reservoir had filled to capacity five separate times. Chicago’s multibillion-dollar anti-flooding system is already struggling to keep up with the region’s larger and more frequent storms.As the article notes, the change in storm intensity over the 50-year construction timeframe exceeded the designers' imaginations. The scary part is that the combined sewers were also a result of lack of foresight by their designers. They were glad at that time to get the sewage out of the gutters and away from the city. Later, they had to re-engineer the Chicago River so that the sewage wouldn't foul the water intakes and cause disease outbreaks. Then, development caused massive flooding because the sewers weren't able to handle the increases in runoff from all of the pavement laid over the formerly pervious soil. Now that they have designed a system to handle the overflows, climate change is causing more intense rainstorms with longer durations. None of our storm infrastructure is built for it. I've been out of the civil field for almost 10 years, so I'm not even sure if the powers-that-be have even tried to grapple with what our design standards should be under the new climate regime. That should terrify people. It sure does me.

Word to the wise. We have endured two 10% corrections in the same year for all three major averages. This has only happened in 1973, 1974, 1987, 2000, 2001, 2002 and 2008. All but 1987 signalled recession, but that wasn't a pretty picture either.— David Rosenberg (@EconguyRosie) November 6, 2018
