  • Twelve climate technologies

    This is an excellent blog post by entrepreneur and venture capitalist Vinod Khosla about some of the “instigators” that are working to help solve our climate crisis and some of the areas in which we probably should be focusing on next. One of the things that’s noteworthy about the post is that he distills it all down into 12 areas of focus that — if solved and if scaled — could have a material impact on carbon emissions. They are (verbatim):

    1. Electric vehicles & automotive batteries
    2. Food & agriculture, especially meat
    3. Low carbon transportation: Air transportation (jet fuel), shipping (electrofuels, biofuels?)
    4. Cement or substitute construction material
    5. Low carbon dispatchable electricity generation (fusion, geothermal, nuclear)
    6. Public transit
    7. Grid storage (long duration battery storage)
    8. HVAC
    9. Industrial processes (hydrogen?)
    10. Fertilizer (hydrogen)
    11. Water
    12. Steel

    Looking at this list, it is clear that some of these things are already happening (and some aren’t). I currently own an ICE vehicle, but I’m fairly certain it will be the last non-electric vehicle I ever own. It’s also not clear whether I will want to continue owning a car. Dynamic mass transit and overall autonomy are things that we’ve talked a lot about on this blog.

    But here’s the other idea put forward in Khosla’s post. If these are in fact the 12 most impactful and important categories, then we may only be 12 or so companies away from real solutions. We only be 12 or so entrepreneurs away from meaningful societal change. When you look at it this way, the climate crisis should hopefully feel a lot less daunting.

  • Sidewalk Labs, Uber, Lime, and the demise of urban density

    Today I am going to talk about 3 things that recently happened and/or that are on my mind.

    Sidewalk Labs pulled out of Toronto. I think this is sad. A lot of people have said that they’re surprised, but not surprised. The official reason is that this unprecedented environment has made it financially infeasible for them to develop the 12-acre site, while still adhering to their core principles. I don’t have any inside knowledge of the situation, but I can’t help but think that this is probably just an opportune excuse. They were getting beat up pretty badly by Toronto on all fronts, even though they had put forward an incredibly ambitious development proposal. As I said before, I can’t imagine many (or any) “conventional” developers coming forward with something like this. The last plan I saw was 1/3 non-residential, and 40% of the residential component was to be priced below market. And never mind all of the other innovations that were being contemplated.

    In other tech news, Uber just led a $170 million investment in Lime (the micromobility scooter company). I think this is smart — both from an overall mobility standpoint and, selfishly, as a shareowner of $UBER. It is being reported that this round of investment values Lime at about $510 million. This is a 79% decline from April 2019 when it raised its last round. So presumably, Uber is getting a pretty good deal here. The bet is that the urban landscape demands multi-modal transportation solutions, everything from bikes and scooters to cars and public transit. There is also an argument to be made that in the short-term, our post-pandemic world is going to gravitate toward individual mobility and away from things like public transit. I’ve heard a few people say that, as we re-open the global economy and try to maintain social distancing, we’re going to face two major mobility bottlenecks: transit and elevators. Sounds like more testing would be a prudent idea.

    Above, I was very careful to say “in the short-term” because I think the narrative that is emerging around the demise of urban density is entirely overblown. Few of us are clamoring to jump back into a mosh pit right now (perhaps a metaphorical mosh pit), but I also don’t believe that we will suddenly look to sprawling Brasilia as a source of urban inspiration. While it is true that “disease did shape architecture in the 20th century” (Alex Bozikovic wrote a good piece on this over the weekend) and that there have been oscillations in terms of how we view urbanity, I also know that this isn’t the first pandemic that our cities have lived through. The Hong Kong flu of 1968 is thought to have killed one million people around the world after, allegedly, emerging in one of the densest cities ever created. Hong Kong’s relationship with Beijing is a tenuous one right now, but it still remains one of the world’s most important global cities.

    Perhaps cities are more resilient than we give them credit for.

  • Examining the solar potential of cities

    The MIT Senseable City Lab recently asked: How does urban morphology affect the solar potential of cities? If you assume that transparent photovoltaic cells are on the way and that building facades are soon going to become a place where we generate solar energy, then this is actually a pretty interesting question. Are some built environments naturally better suited than others?

    To answer this question, they looked at the “urban surfaces” of ten cities, including New York, Singapore, Toronto (pictured above), Hong Kong, Paris, as well as others. These surfaces included roofs, facades, and ground planes.

    What they, not surprisingly, discovered is that you need a lot of exposed facades to get the numbers up. And so the cities that come out on top in terms of annual solar irradiation are cities like New York and Singapore. They have a lot of tall buildings, but they also fluctuate in height, giving greater exposure to the facades.

    All of this is potentially relevant because — if building facades become a big deal for solar — it could start to inform how we plan our cities. In fact, I would go so far as to bet that, over the long-term, solar energy will have a greater impact on urban morphologies than this current pandemic.

  • Koto Design announces prefab partnership and two new house designs

    Koto Design, which I have written about before on the blog, has just announced both a partnership with Plant Prefab and two new home designs. Koto is based in the UK and is a designer of small and energy neutral homes and cabins. Plant Prefab is based in the US and is, according to Koto, the first prefabrication company entirely dedicated to sustainable building practices. This partnership — called Koto LivingHomes — now means that Koto’s designs are available for delivery in the US.

    The smaller of the two new designs is the Yksi House. It consists of two stacked volumes (pictured above) and is about 1,000 square feet. The ground floor has two bedrooms and the second floor houses the main living area. This allows the exposed roof areas of the lower volume to serve as outdoor spaces. You also naturally get better views from up top, which is one of the reasons why this configuration is so common across many vernaculars.

    If you’d like to play around with the Yksi House in 3D (directly in your browser), you can do that over here. It’s a wonderfully simple design. I know that the building industry has been talking about and experimenting with prefabrication for many generations (and it has never stuck), but I can’t help but think that as beautiful products like these become far more accessible and affordable, we might finally make it happen.

  • A post corona world

    There’s a lot of speculation (that’s all you can really do) about what our world is going to look like on the other side of this pandemic.

    I think it’s easy to overreach at a time like this and prognosticate dramatic change — such as the demise of cities and urbanity as we know it. But while I do believe that there are bound to be changes, I also know that after 9/11 most of us eventually stopped being afraid of flying and of being in tall buildings. We forgot and moved on.

    So, what might change?

    Scott Galloway argued on his blog today that “things won’t change as much as they will accelerate.” In other words, this pandemic is simply going to make the future happen faster. And one of those things is going to be a faster shift to online for higher education. It is untenable for education costs to continue increasing at the pace that they have been.

    In this recent Intelligencer interview with Chamath Palihapitiya, he puts forward the idea that medical data might start to be used publicly. Meaning that, after this is all done, we might be willing to give up a certain amount of our personal freedom in exchange for knowing whether we’re in a restaurant with someone who is shedding a communicable disease.

    And finally, Richard Florida recently published this online talk about how cities can bounce back from COVID-19. In it, he argues that, yes, cities will survive and that it could actually reinforce the “winner-take-all urbanism” that we have already been seeing.

    This, of course, is really just the start of the conversation.

  • Mapping spring breakers

    The following video was published last week showing the “secondary locations of anonymized mobile devices that were active at a single Ft. Lauderdale beach during spring break.” Said differently, the company used anonymized mobile phone data to see where spring breakers went after they left the beach. This was in order to better understand how they may have contributed to the spread of COVID-19. If you can’t see the video below, click here.

    The video is astonishing for two reasons. One, it shows you the extreme reach of just one beach in South Florida. Imagine if they had analyzed all of the beaches up and down the coast. And two, a lot of you are probably freaked out that this sort of mobile phone data is available to private companies. If you’d like to learn more about how this all works, check out this opinion piece from the New York Times.

  • How to respond to the coronavirus

    I just finished watching this TED talk with Bill Gates. For those of you who are up on their TED talks, this is not the one from five years ago where Bill predicted a pandemic and told us all that we were nowhere near ready. (We, of course, didn’t listen.) This is one that was published a few days ago and talks about how we should be responding to the outbreak that we are currently living through. The Bill & Melinda Gates Foundation has been committing significant resources toward solving problems exactly like this one. So it’s interesting to hear his thoughts. In case you’re wondering, herd immunity isn’t the answer. We need (1) widespread testing and (2) to be extremely disciplined about our social distancing. In his words: “But money, you know bringing the economy back and doing money, that’s more of a reversible thing than bringing people back to life.”

  • Leveraging mobile phone data during a pandemic

    Smartphone user data is hugely valuable at a time like this. Which is why governments all over the world from Israel to South Korea are using aggregated telecom data to try and track how their citizens are moving during this pandemic.

    Some are calling this a violation of digital rights. I don’t know enough to comment on that specifically, but I do know that the value to society as a whole is clear. It strikes me that if we knew (1) who was infected (you know this by doing widespread testing), (2) where people have been, and (3) where people are today, we would be in a much better position to contain the spread.

    To that end, Singapore’s Ministry of Health has been publicizing a surprising amount of information regarding its cases. And that data has been in turn made into interactive maps. You can see who is infected, where they live and work, which hospital they were admitted to, and so on. Is this an overshare? Or is this price of collective health and security?

    The New York Times has similarly gone and visualized the movement of people and the virus using data from major telecoms, Baidu, and other sources; though in this case it is more of a retrospective view of what went wrong as opposed to a proactive management tool. The argument they make is that Wuhan’s lockdown was too little, too late.

    According to the NY Times, 175,000 people left Wuhan on January 1st alone. Throughout the month of January, outbound travel from Wuhan accelerated as many started to fear a lockdown. About 7 million people left in January. Where they travelled to can be found here. Would it be too draconian to use this kind of mobile phone data to see who is obeying a lockdown and who is not?

  • Nurx announces home testing kit

    I have been debating whether I should continue writing about what is already on all of our minds, or if I should focus my attention on positivity and humor. The latter is hugely important at a time like this, which is why I have been trying to intersperse my thoughts, both here and on Twitter, with things like funny videos, dance music, and architecture.

    But the reality is that none of us know how this is all going to play out. As I mentioned yesterday, very few of us have a mental model for this kind of macro event. So it’s important for all of us to continue learning. Is our country taking the right approach? Are we doing enough? How long are we going to have to live like this and what does that mean for the global economy?

    The Financial Times published an invaluable story earlier this week about a small town outside of Venice called, Vò. With only 3,300 people, the town was supposedly able to test and retest all of its residents while the rest of northern Italy was growing as an epicenter for the Wuhan virus.

    In late February, they completed their first round of testing and found that about 3% of the town had been infected. But it’s important to note that about 50% of those that were infected were completely asymptomatic! However, because everyone was tested, the asymptomatic people got immediately quarantined.

    The town did a second round of testing about 10 days later and that point the infection rate had dropped to about 0.3%. Of course, if all those asymptomatic people had been out and about in the town of Vò, this would not have been the case. There now appears to be no new cases in Vò.

    It is for this reason that the WHO is urging diligent and repeated testing. But that obviously needs to be done in a sensible way. Having people line up — together — for hours upon hours is an obvious problem. Most people are not getting tested.

    Earlier this morning, San Francisco-based Nurx announced a home testing kit for the Wuhan virus. Supposedly it is the first of its kind in the US. (It’s not yet available in Canada — I asked). I don’t know how available it is to Americans or how accurate it is, yet, but I do know that something like this needs to become widespread.

  • How temperature impacts the transmission of COVID-19

    The Financial Times published the following chart last night. It shows the cumulative number of COVID-19 cases around the world, across the number of days since the 100th case in that particular country. The message here is that most western countries appear to be on a similar trajectory. (The grey dotted line represents a 33% daily increase.) Whereas in Asia, and in particular Hong Kong and Singapore, they have seemingly managed to slow the spread.

    Now, there are a number of possible explanations for the outliers; everything from stricter quarantine rules to more rigorous testing. There’s also an argument that Hong Kong and Singapore were better prepared as a result of the SARS outbreak in 2002. (More on these explanations, here.) But the other factor at play seems to be climate.

    A recent study (by Jingyuan Wang, Ke Tang, Kai Feng, and Weifeng Lv) has concluded that, like the flu, the transmission of COVID-19 appears to be significantly impacted by both air temperature and relative humidity. In their research, they looked at the reproductive number (R), or the severity of infectiousness, for all Chinese cities with more than 40 cases between January 21 to 23, 2020. (Large-scale government interventions began on January 24, 2020 and would have therefore skewed the numbers.)

    What they found was that for every one degree Celsius increase in temperature and every one degree Celsius increase in relative humidity, the reproductive numbers drop by 0.0383 and 0.0224, respectively. Air temperature, in other words, has more of a positive impact on containing spread than relative humidity — which feels right. That is also apparent when you look at the above charts. Take note of Korea, Iran, and Italy near the top left corner of the temperature chart.
