“Landing of Spanish Colonists in the Port of Algiers” by Pierre Emile Gigoux de Grandpre, via Invaluable. Welcome to the reading list, a weekly roundup of news and links related to buildings, infrastructure and industrial technology. This week we look at Trump refusing to sign a housing bill, the high cost of US-made doors, slow trucking, why we stopped making new land, and more.

I wrote the following piece for IFP’s Transit Abundance Playbook, a collection of 15 ideas to improve transit delivery in the US. American transit costs and timelines are substantially higher than those of other developed countries: Spain builds tunneled subway for ~$200 million per mile, while New York spends billions; China built an entire network of high-speed rail while California was failing to connect Bakersfield to Merced.

Old Buildings on the Darro, Granada by David Roberts, via Wikipedia. Welcome to the reading list, a weekly roundup of news and links related to buildings, infrastructure, and industrial technology. This week we look at a new housing bill, General Motors joining the grid-scale battery game, skepticism about data center delays, solid-state air conditioning, and more.

For the better part of the last several hundred years, coal was the fuel of choice for generating power. Burning coal powered Thomas Newcomen’s steam engine, invented in Britain in the early 18th century, and the first of a line of increasingly efficient converters of coal to usable energy. The Newcomen engine was in fact so inefficient and consumed so much coal that it was almost exclusively used at coal mines, where fuel could be obtained cheaply.

“The Campo di SS. Giovanni e Paolo, Venice,” by Bernardo Bellotto, via the National Gallery of Art. Welcome to the reading list, a weekly roundup of news and links related to buildings, infrastructure and industrial technology. This week we look at homes being built on top of libraries, Patriot missile manufacturing, an effort to construct new US coal plants, a tunnel between the US and Russia, and more.

A few weeks ago we looked at a simulation of technological evolution by economist Brian Arthur, in which he was able to start with simple building blocks (such as a NAND gate) and evolve surprisingly complex circuits (such as a 12-way AND gate or a 4-bit adder) by randomly combining increasingly useful existing components.

“Glasgow, Saturday Night” by John Atkinson Grimshaw, via Wikipedia. Welcome to the reading list, a weekly roundup of news and links related to buildings, infrastructure and industrial technology. This week we look at chatbots replacing realtors, Chinese synthetic diamonds, Australian batteries, Meta’s data center tents, and more.

Bear Mountain Bridge in New York, via Wikipedia. Many folks, includingme, have observed that it seems to take much longer to build infrastructure in the US than it used to. People point to things like the rapid construction of the Empire State Building (one year) or the Golden Gate Bridge (just over four years) and note that for a modern infrastructure project it can take that long or longer to even get the permits or do the environmental studies.

House building using the “Oraaflex” modular construction system, via Wikipedia. Welcome to the reading list, a weekly roundup of news and links related to buildings, infrastructure and industrial technology. This week we look at a California chemical leak, weapons-grade plutonium for nuclear reactor startups, a startup that will clean your house to get robot training data, Blue Origin’s rocket explosion, and more.

Over the last few months we’ve examined the extent of the construction industry’s productivity problem. We’ve looked at a variety of construction productivity metrics, both for the US and for countries around the world, and found that construction productivity almost always rises much less in construction than it does in industries like manufacturing; often, it doesn’t improve at all.
