Brandon DonnellyCanada must become a global superpower
The silver lining to the US starting a trade war with Canada and regularly threatening annexation is that it has forced this country out of complacency. Indeed, I'm hard pressed to remember a time, at least in my lifetime, when patriotism and nationalism has united so much of Canada. According to a recent survey by Angus Reid, the percentage of Canadians expressing a "deep emotional attachment" to the country jumped from 49% in December 2024 to 59% in February 2025. And as further evidence of...
Brandon DonnellyThe bank robbery capital of the world
Between 1985 and 1995, Los Angeles' retail bank branches were robbed some 17,106 times. In 1992, which was the the city's worst year for robberies, the number was 2,641. This roughly translated into about one bank robbery every 45 minutes of each banking day. All of this, according to this CrimeReads piece by Peter Houlahan, gave Los Angeles the dubious title of "The Bank Robbery Capital of the World" during this time period. So what caused this? Well according to Peter it was facil...
Brandon DonnellyThe story behind those pixelated video game mosaics in Paris
If you've ever been to Paris, you've probably noticed the small pixelated art pieces that are scattered all around the city on buildings and various other hard surfaces. Or maybe you haven't seen or noticed them in Paris, but you've seen similarly pixelated mosaics in one of the other 79 cities around the world where they can be found. Or maybe you have no idea what I'm talking about right now. Huh? Here's an example from Bolivia (click here if you can't see...

Brandon DonnellyTesla introduces a battery for your home
By accident, this week on Architect This City seems to be turning into Elon Musk week.
Yesterday, Musk announced something called the Powerwall home battery. Measuring about 3′ x 4′, the shield looking battery pack will charge using the electricity generated from solar panels (or from the grid when rates are at their lowest) and then power your home.
It’s designed for consumers and will cost between US$3,000 - $3,500 depending on capacity. The individual Powerwalls can also be daisy chained to increase capacity. It will be available starting this summer.
A wall battery may not seem all that interesting to some, but I think this is actually a big deal for a few reasons.
Renewable energy is often both intermittent and produced when you don’t need it. Here’s a great chart from Tesla that shows what I mean:
During peak solar hours, most people aren’t home and most people aren’t consuming at peak levels. That’s why it’s important to be able to store the energy that you collect, whether it be from solar, wind or other renewal energy source. And from what I hear from my friends in the industry, storage has been a bit of an Achilles heel for adoption.
It will also help to further decentralize energy production. What is produced locally (from say solar panels) will be stored locally for when it’s needed locally. This is in contrast to centralized production or producing energy locally and then feeding any excess capacity into the grid for use somewhere else. That requires transmission and will be by definition less efficient.
Finally, the other interesting thing about Powerwall is that it closes the loop on two of Musk’s businesses: SolarCity and Tesla. SolarCity is about the production of renewable energy and Tesla is about the consumption renewable energy. But as the chart above shows, storage is often needed to link those two activities in an efficient way.
All of this makes me excited about Powerwall.
If any of you are an expert in this industry (which I am not) or you just have additional thoughts, I would love to hear from you in the comment section below.
