It's a new Stone Age in London, with stone apartment buildings and a stone demonstrator exhibit showing how it's done. Because it is silly to grind up limestone, cook it, and then add water to turn it into... stone. We could be doing a lot more of this in Canada- we are made of rock.

lloydalter.substack.comThe Stone Demonstrator shows us how to build for a New Stone AgeWhy grind up rock to make concrete when you can use natural materials like wood and stone?

Doug Ford should move to Iowa. He could build a spa and rip up bike lanes and leave us alone.

Joe Mitchell: "Thank God you're building the ballroom. Thank God you're getting rid of those awful bike lanes. We don't ride bicycles in Iowa."

William McDonough jokes that it took 5,000 years to figure out how to put wheels on luggage, demonstrating that design is hard. Trying to walk on the streets of London, I think it was a mistake.

I am reading this in London UK where there are just thousands of people on bikes everywhere, congestion charges and clean air charges and traffic is still slow because successful cities are congested, people want to live there!

While walking Bloor Street West this week, my sadness and anger became a white hot rage after being nearly struck by a SUV driver while I was in a marked crosswalk. seanmarshall.ca/2026/10/17/t...

This is such a terrible idea, so incredibly inefficient, such a waste of aluminum! I have written about this process before and called it incredibly silly. www.treehugger.com/why-make-hyd...

treehugger.comWhy Would You Make Hydrogen From Aluminum?Because you can. But it doesn't mean that it makes any sense.

Aluminum-Air Generators (AAG) are a direct replacement for diesel generators. They consume solid recycled aluminum plates as fuel, which combined with oxygen from the air and a liquid electrolyte like saltwater generate clean electricity on demand.

I have often complained that  “The big fridge, the big car, and the big grocery store are all part of one economic machine; in a sense, you cannot have one without the other two.” Now people are installing special "costco doors" to make it easier to move stuff from car to fridge.

Gee, I thought Kingspan promised to stop lying after Grenfell

Kingspan has been fined by EU regulators for providing incorrect and misleading information relating to the acquisition of another company. Read more at: passivehouseplus.ie/news/governm...

I am not posting a photo of my huge black eye, but those smudges on the glass door of a lovely restaurant in our neighbourhood are where my forehead and nose smacked into it. Seriously, if you have a glass door, put some markers on it. You have to do it for birds, why not do it for people too

This was an extraordinary takedown, everyone should read it and post it everywhere

I had breakfast with Brad Bradford and asked him what I think is the defining question of his campaign: Why do so many people from all ends of the political spectrum seem to dislike him so much as a person? www.thestar.com/opinion/cont...

I think Toronto worked a bit of magic on Kevin. Love his T-shirt

The starting pitcher that the Cubs acquired from the Toronto Blue Jays appeared at Wrigley Field today on a cargo bike! Gausman knows what’s up

You try climbing up a scaffold and lifting bricks for 40 years. It’s why bricklaying is one of the first trades that will be roboticised or eliminated.

This post is unavailable.

There is a reason that @thestar.com does a major exposé on car theft a month before the election: to build a sense of fear and push bradbrad's candidacy. It's not just social media, it's all the media.

Social media is playing a role in this; Next Door is a cursed platform. Visible disorder has increased certainly; howling, staggering, open drug use. But is there safer big city in North America than Toronto?https://www.cbc.ca/news/canada/toronto/toronto-safety-perceptions-mayoral-campaign-9.7364433

I hate it when charities send a huge package of shit, even with my name printed on the pen and cards, hoping I will be guilted into a donation. Supposedly if 5% of the people who get these donate then it covers their costs, but how much of this stuff ends in the trash. It should be banned.

This is great. I love seeing the falsework holding up the arch

Toronto, 110 years ago today: Building the Bloor Viaduct over the Don River, Sept. 25, 1916. I digitally edited three separate City of Toronto Archives images together to bring this panorama together. #onthisday #1910s #torontohistory #architecture #jeremyhopkin

My late mom had a mantra for living in Toronto: "Never breathe the air north of St. Clair." She was right; I had a meeting that was supposed to be a 13-minute walk from the subway, but I spent that much time just trying to get out of the station and ended up on the wrong side of Steeles.

Finally got to my destination, which I entered like a car on a driveway; the actual main entrance faces... nothing. Gorgeous building, worth the trip, but my mother was right.

Then the walk went past an open field; I cannot imagine what it is like in winter. I almost got killed in a roundabout with no stop signs or crosswalks and a lot of drivers honking because they don't understand roundabouts.

It sure looks like @thestar.com is in the tank for BradBrad, running bullshit headlines and a push poll with loaded negative questions about traffic and safety, two of his favourite hot buttons. All manufactured outrage.

A new initiative in the UK tries to change the way we look at the built environment: “Housing, planning, transport, infrastructure, energy and regeneration aren't separate problems — they're one industry, hiding in plain sight.” Yet we are in separate silos, often working at cross-purposes.

lloydalter.substack.com“One Built Environment” unites all strands of construction, transportation, and infrastructureThis British report proposes breaking down silos and recognizing that everything is connected. We should be doing this everywhere.

I concur, not a good look

Charlie Angus@charlieangus104.bsky.social

Not a good look: arresting seniors calling on Mark Carney to not walk back our climate obligations. In my last 2 years as MP I ran a gauntlet of threat, swarming and harassment everyday from conspiracy ragers. House security and Ottawa police just watched. Seems instructions have been issued.
