the Trump infrastructure bill

The Trump infrastructure plan has apparently leaked. The upshot seems to be that states and metropolitan planning organizations, among others, can submit projects to be matched at up to 20% by the federal government. Most of the selection criteria are based on making a strong case that there is a plan to come up with the other 80%.

This sounds okay, as far as it goes, and it might get some projects over the hump that would not otherwise get built. I like the idea that metropolitan planning organizations are eligible, because they are in the best position to look at a city’s needs as a whole, across fragmented political entities and across types of infrastructure. Cities are where people live, where most of the economy happens and taxes are paid, and where people are educated and given skills and where new ideas come from that make our lives better in the long run. What I don’t really like is that economic and social benefits are given only 5% weight in the selection criteria. And even then, they are considered for an individual project in isolation, in the absence of any larger plan. In my ideal world, planning organizations would have comprehensive infrastructure plans that look at all types of infrastructure together over the long term, even including green infrastructure, and really focus on maximizing economic benefits. This would allow us to prioritize individual projects in the larger context of how the whole socioeconomic system works and not just on one “project at a time.

Still, this might be a small step in the right direction. Along with public infrastructure and some small steps to encourage capital investment, research and development in the private sector, add serious programs to address education, job skills training, and research and development in the public sector and you would have the beginnings of a long term national economic plan. Maybe toss in a revenue-neutral pollution tax for good measure.

Biophilic Cities

Biophilic Cities is a group trying to create “cities of abundant nature in close proximity to large numbers of urbanites. Biophilic cities value residents innate connection and access to nature through abundant opportunities to be outside and to enjoy the multisensory aspects of nature by protecting and promoting nature within the city.” This seems a bit big picture and visionary, but they also have some practical resources such a collection of codes and ordinances used by various cities.

brain scans can see your mind’s eye

Scientists in Japan now have a brain scan that can recreate an image in someone’s minds eye fairly accurately. This could have positive applications, for example to help the disabled. The security and big brother implications seem a bit ominous though.

As the accuracy of the technology continues to improve, the potential applications are mind-boggling. The visualization technology would allow you to draw pictures or make art simply by imagining something; your dreams could be visualized by a computer; the hallucinations of psychiatric patients could be visualized aiding in their care; and brain-machine interfaces may one day allow communication with imagery or thoughts, Kamitani tells CNBC Make It.

While the idea of computers reading your brain may sound positively Jetson-esque, the Japanese researchers aren’t alone in their futuristic work to connect the brain with computing power.

For example, former GoogleX-er Mary Lou Jepsen is working to build a hat that will make telepathy possible within the decade, and entrepreneur Bryan Johnson is working to build computer chips to implant in the brain to improve neurological functions.

record U.S. weather disasters in 2017

Major hurricanes, fires and floods set a new record for the cost of damage in the U.S. in 2017. Setting aside the human misery caused, natural disasters tend to provide a short-term economic stimulus, because it is rare time that politicians tend to set aside their differences and borrow or print money as necessary to solve the problem. In the longer term though, I can’t help thinking that this is one way climate change can make us poorer, because we will be spending money and effort dealing with a higher rate of disasters that we could otherwise be spending on more productive work, investment or innovation. The other way climate change can make us poorer is just the long, slow grind of rising energy, food and water prices. I can imagine these two trends working together, where we are adapting to that long, slow grind, but when the disasters hit we no longer have the ability to recover completely like we used to. This is not unlike a stressed ecosystem that manages to hang on until that fire or flood hits, but then does not have the soil conditions or the seed bank or whatever to rejuvenate itself in the same spot after it gets wiped out.

household-scale biogas

It makes a lot of sense to combine sewage, yard waste and food waste in an anaerobic reactor to produce methane, which can be used for heat, to fuel vehicles, to generate electricity, or even to power fuel cells. This is done sometimes at a city or utility scale, but people haven’t really tried to do it in their basements. This article is about an attempt to do that in Yemen.

reading and the brain

There is a fair amount of evidence that reading is good for the brain. One of the reasons is that reading narratives and having to get into the characters’ heads helps to build empathy in real life.

Improved theory of mind comes primarily from reading narratives, research suggests. One meta-analysis published by Raymond A. Mar of Toronto’s York University reviews many of the studies demonstrating the effect of story comprehension on theory of mind, and concludes that the better we understand the events in a narrative, the better we are able to understand the actions and intentions of those around us. The kinds of narratives we read, moreover, might also make a difference. One study, conducted by psychologists David Comer Kidd and Emanuele Castano of the New School for Social Research, tested the effect of differences in writing quality on empathy responses, randomly assigning 1,000 participants excerpts from both popular bestsellers and literary fiction.

The type of writing appears to matter, with more literary fiction helping more than best-sellers or non-fiction. A piece of good news is that audiobooks seem to be fine. The article doesn’t get into electronic vs. paper forms of reading, or reading vs. television or video games. It does quote one neuroscientist who questions whether reading is really special compared to other forms of experience.

One hypothesis I have, based on my own experience with people who can’t read in two different corners of the world, is that reading could change the nature of a person’s verbal skills, and not necessarily for the better. People who can’t read sometimes have the “gift of gab”, are good storytellers, and are good at teaching children to speak their native language. And similar to teaching small children, they can be incredibly patient with illiterate foreigners like myself, where an educated person would not have the patience, or somehow, maybe not have the empathy, to do that. So while I think reading and writing and certainly very important to our species, they also may have changed us along the way.

experimental quad-copter at Boeing

Boeing has an experimental quad-copter that can lift 500 pounds. The way they describe it, this could fill a niche between shipping of huge containers and delivery of tiny parcels to your door.

This kind of vehicle may not fit into your drone delivery fantasy, but it has practicality on its side. “This starts to sound like the kind of thing that can do things in real life,” says Drew McElroy, CEO of Transfix, a trucking brokerage firm. As home deliveries have grown in popularity over the past 15 years or so, he says, shipments have gotten smaller, and more targeted. The old model—trucks haul supplies to Walmart, people drive to Walmart and bring home their shopping—is evaporating. Any vehicle that can fill in the gaps between the huge bulk shipments that move by sea and the shoebox-sized packages that come to our doors can play a role.

The other interesting thing about the article is a brief description of the R&D unit that developed this thing.

In fact, Boeing isn’t quite sure where it’s going. “It’s a concurrent exploration of a nascent market and nascent technology,” says Pete Kunz, the chief technologist for HorizonX, the Boeing skunk works-venture capital arm hybrid division ///something like that/// that built this thing (the marketing team hasn’t given it a catchy moniker yet)…

Exactly what it will carry and where it will take it remains an open question. Boeing doesn’t have any concrete plans or timelines for commercialization yet, but Logan Jones, HorizonX’s senior director, says it could tote supplies to offshore oil rigs, or any other “dull, dirty, and dangerous” work now done by helicopters, which require expensive human pilots. It could take pallets from a port to a distribution center, or from a distribution center to a store. “This won’t show up at your door,” Jones says. (This is a commercial project, but it’s easy to see potential military applications, like moving supplies around combat areas.)
