I think this reflects our confused spiritual relationship with our own past. We feel a strong and intuitive affinity for what we used to build, while our contemporary frameworks consider such buildings misguided and "immoral". The mind says massing prohibitions and setbacks; the heart says beautiful masonry, higgeldy-piggeldy layouts, and Victorians. Rather than resolve the tension, we designate large fractions of our city ontologically confused, simultaneously protected and illegal; sanctified and condemned.

I'm interested in "trapped buildings": those that couldn't be built today (because of zoning and code changes) but also can't be substantially modified or demolished (because of historic protection rules). One of those phenomena that really makes one wonder what exactly we're trying to do. Has anyone ever estimated what fraction of buildings in major cities fall into this category? When I asked Claude about San Francisco, it concluded: "If forced to give a single number with a single confidence rating: roughly 100,000 buildings — about two-thirds of San Francisco's physical structures — sit in the trap as a practical matter. Confidence: moderate. The number could be 70,000 or 130,000 depending on how strictly you operationalize "can't be substantially modified.""

@CJHandmer @TerraformIndies How much would you benefit from capturing CO2 from a richer stream like exhaust of a generator? Obviously not a perpetual motion machine but could you focus on electrolyzer and methane generation and come back to very diffuse atmos co2 capture later?

The Alamada airfield could be a neo-Shenzhen SEZ for SF Bay Area. Could be a 30% GDP growth impact on USA if truly deregulated.

This 100MW data center in UAE is the largest solar powered datacenter in the world. There are currently 1,300 data centers in the world that are bigger than this one, but this one is the largest solar powered one. That’s 10 square kilometres of solar panels you can see. The datacenter itself is 0.02 square kilometres, so a solar powered datacenter is ~500x larger than a data center using any other form of power. A five hundred times larger site. UAE has some of the highest solar irradiance anywhere on Earth, it is an inhospitable desert. Averaging 9.7 hours of sunlight per day with average irradiance above 2,200 kWh/m^2. If you build this somewhere else, you need more solar panels because your irradiance will almost certainly be lower. Even if the world had an infinite supply of free solar panels, solar power will not be free. Anyone who has ever done major capital projects, who looks at where data centers need to be in the next 5 years and the next 10 years… we know it aint solar. Sorry. You struggle to even build a train track that’s 100 miles long and 10ft wide anywhere in the West, there is zero chance of build 100 square mile solar farms for GW compute. This is why people are talking about space compute. Deploying into space is one strategy to solve the constraints. But there are faster and more scalable strategies, that get you to mass deployment of multi GW data centers. There are strategies that also allow you to power the 10 billion robots and their newtonian actuators, that immediately follow the inference demand cycle. Step back and look at the full cycle of this industrial revolution… There will be billions of chips, but there will be trillions of actuators. This biggest part of this revolution is the embodiment cycle, and it’s big by a factor of 20 or 50x over the stuff that comes before it. There is no analogy in human history for the scale of this economy, of the demand it will place on energy and commodities. The humans own the Earth, and if you exist inside their legal system, they won’t let you turn the surface of their planet into glass. But they do want your chips and your actuators to serve their needs and desires. There is a way to do all of this, and so it will happen.
