Apparently, this story popped up back in 2015, but it's so cool that it's still worth reading about now: the city of Portland, Oregon has water pipes buried underneath of it that not only carry clean drinking water to the locals, but also generate hydroelectric power at the same time!

From Fast Company:

In Portland, one of the city's main pipelines now uses Lucid's pipes to make power that's sent into the grid. Though the system can't generate enough energy for an entire city, the pipes can power individual buildings like a school or library, or help offset a city's total energy bill. Unlike wind or solar power, the system can generate electricity at any time of day, regardless of weather, since the pipes always have water flowing through them.

The pipes can't generate power in every location; they only work in places where water is naturally flowing downward with gravity (if water is being pumped, the system would waste energy). But they have another feature that can be used anywhere: The pipes have sensors that can monitor water, something that utilities couldn't do in the past.

Providing power to partially operate water treatment and pump facilities during the day and then juice up streetlights at night: what's not to love about that? Read the rest

YouTuber euverus modded Cities: Skylines to demonstrate how 30 different types of intersections have dramatically different amounts of traffic flow. A four-way intersection with no traffic lights gets a flow of 191 vehicles per minute, where a stack interchange can handle 1099 vehicles in the same time frame.

The mods used, Traffic Manager: President Edition and Network Extensions 2, are both available for free on Steam.

The big surprise for me was the roundabout, because we rarely have them in the Midwest or the West Coast. They seemed like a lot of extra space needed for an incremental benefit, but it appears they can be more efficient and safer, even weird ones.

This week on HOME: Stories From L.A., a member of the Boing Boing Podcast Network:

HGTV and glossy magazines have sparked a boomlet of interest in tiny homes, but they've also made them look fun, cute and easy. The realities of a tiny lifestyle can be more daunting. Municipalities often don't know what to make of tiny houses, and living in one legally is, in many places, challenging. There's a lack of infrastructure for people who want to build them. And although they're in many ways an imaginative solution to some of the most vexing urban housing issues, they don't yet have a high profile in cities. Is there a place for tiny homes in Los Angeles? One woman thinks so, and has founded a collective of like-minded people to make it happen.

A new study of driver attitudes toward bikers shows that being able to perceive cyclists is influenced by driver attitudes toward cyclists. Those who don't like or don't care about cyclists don't see them even when looking at them. They also found that the social dominance of vehicles means they have a far higher degree of lethality over "alternative" transportation like biking or walking: Read the rest

Robert Moses gets remembered as the father of New York's modern urban plan, the "master builder" who led the proliferation of public benefit corporations, gave NYC its UN buildings and World's Fairs, and the New Deal renaissance of the city: he was also an avowed racist who did everything he could to punish and exclude people of color who lived in New York, and the legacy of his architecture-level discrimination lives on in the city today.

Back in November 2012, the New York Department of Transportation released a report called Measuring the Street: New Metrics for the 21st Century, which had some compelling figures on the way that local business benefits from bike-lanes, for the fairly obvious reason that cyclists find it easy to stop and shop, as compared to drivers, who are more likely to continue on to a mall with a big parking lot, or shop online.

In many ways, these data come as no surprise. We know that when towns invest in bicycle infrastructure, people will ride more — the number of people traveling by bicycle increases when there is infrastructure to make traveling by bike safe and easy.

We also know that people who travel along a street by bicycle have fewer barriers to stopping at a local business than people who travel along the same street by car. It's very easy to hop off a bicycle and find a place to secure the bike; not so with finding parking for an automobile. In fact, a recent study suggest that bicycle riders tend to spend more at local businesses over the course of a month.

This new study makes it clear: investing in bicycle improvements boosts small businesses. And what town or city doesn't want to boost activity at local businesses?

In an excellent NYT story, Sarah Lyall reports on "lights-out London" -- the phenomenon whereby ultra-wealthy foreigners (often from corrupt plutocracies like Kazakhstan and Russia) are buying up whole neighbourhoods in London, driving up house-prices beyond the reach of locals, and then treating their houses as holiday homes. They stay for a couple weeks once or twice a year, leaving whole neighbourhoods vacant and shuttered through most of the year, which kills the local businesses and turns central London into something of a ghost town.

“Some of the richest people in the world are buying property here as an investment,” [Paul Dimoldenberg, leader of the Labour opposition in Westminster Council] said. “They may live here for a fortnight in the summer, but for the rest of the year they’re contributing nothing to the local economy. The specter of new buildings where there are no lights on is a real problem...”

Meanwhile, prices are rising beyond expectation. For single-family housing in the prime areas of London, British buyers spend an average of $2.25 million, Ms. Barnes said, while foreign buyers spend an average of $3.75 million, which increases to $7.5 million if they are from Russia or the Middle East...

The most visible, and also the most notorious, of the new developments is One Hyde Park, a $1.7 billion apartment building of stratospheric opulence on a prime corner in Knightsbridge, near Harvey Nichols, the park and the Mandarin Oriental Hotel, which functions as a 24-hour concierge service for residents. Apartments there have been purchased mostly by foreign buyers who hide their identities behind murky offshore companies registered to tax havens like the Isle of Man and the Cayman Islands.
