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.

Elon Musk is one hell of an entrepreneur. I just finished watching this “Bloomberg Risk Takers” video.
[youtube https://www.youtube.com/watch?v=mh45igK4Esw?rel=0&w=560&h=315]
It’s about 45 minutes long, but well worth it. What’s astounding is both is willingness to go all-in and his commitment to solving big, meaningful problems. Click here if you can’t see the video above.
Once you’re done watching, you should then read this Quora answer from his first wife talking about what it takes to be that great.

Yesterday I posted a video about the career of Elon Musk. And it reminded me of something that’s been on my mind as I think about transportation, cities, and the future.
Elon’s story for why he founded SolarCity, Tesla, and SpaceX is incredibly compelling. He chose problems and industries that he felt would move humanity forward. He felt that we needed sustainable forms of energy production (SolarCity), sustainable forms of transport (Tesla), and a way for humans to occupy other planets (SpaceX). That’s incredible ambition.
Today though, I just want to focus on the transportation piece.
Electric and driverless vehicles, I believe, are a step in the right direction. I honestly believe that at some point in the not too distant future we’re going to look back at that time when people used to drive their own cars and wonder how we ever allowed that to happen.
But fundamentally, I think there still remains a question of how best to plan our cities.
There’s lots of talk today about peak car and the death of the automobile. Certainly within planning and urbanist circles, there’s an almost universal belief that planning (most of) our cities around the car, as opposed to people, was a huge mistake. Multimodal solutions with a public transit backbone are now the way forward.
But will that always be the case as the notion of the “car” evolves?
Intuitively, driverless vehicles feels like a massive opportunity to leverage data and better optimize our private transport assets. We know that the utilization rate for most private cars is incredibly low and so there’s lots of room to improve how we use and share private vehicles and how we move people around cities.
But how big is that opportunity? Does a city filled with driverless electric vehicles and with networks like Uber mean that public transportation now becomes less important? And if so, how much less important?
I can’t help but feel like private and public transport are on a collision course right now. I suppose that isn’t anything new. But this time around I wonder if private transport won’t figure out a way to achieve similar efficiencies to large scale public transport.
