The team at Terraform Industries is now 11 people working towards a near term future where atmospheric CO2, much of it centuries of unpriced industrial waste, becomes the preferred default source of industrial carbon. Our family of technologies will displace drilling and mining as sources of carbon and, in the process, stop the net flux of carbon from the crust into the atmosphere and oceans that is causing anthropogenic climate change. Our process works by using solar power to split water into hydrogen and oxygen, concentrating CO2 from the atmosphere, then combining CO2 and hydrogen to form natural gas. Very … Continue reading We’re going to need a lot of solar panels

Part of the series on common misconceptions in space journalism. A follow on from a previous post on terraforming. As far as terraforming goes, I’ve recently been much more occupied with my startup Terraform Industries, but it still generalizes to creating technical and economic ways to continue the ancient human project of gardening our surroundings to be less unpleasant. By the time Terraform Industries has completed its mission on Earth we’ll have finally assumed intentional and granular control over the world’s carbon cycle and parts of its water cycle, and in turn its position of radiative equilibrium with respect to … Continue reading How to terraform Mars for $10b in 10 years

Part of my series on misconceptions in space journalism, which by this point we may as well admit is really just a paper thin cover for me to write a seemingly endless series of blogs on esoteric space topics. I’ve previously written a bit about powering a potential lunar base. The vision is that we want a decent sized, permanently occupied lunar base, probably at the lunar south pole. Generally speaking, the Moon “enjoys” 14 day (~340 hr) long days followed by 14 day long nights. This makes consistent levels of power a challenge over night. In particular, a solar+battery … Continue reading Powering the lunar base, version 2

I have Thoughts about city design and traffic congestion, so I will write a blog. In terms of background, I did a bunch of transport economics when I worked at Hyperloop, including building a predictive demand model (yes, really!). I’ve also traveled to about 50 countries and taken every mode of transport imaginable from unicycle to helicopter. I lived in LA without a car for 7 years, walking or cycling everywhere. That said, I’m not a credentialed traffic engineer or town planner, which might not be a bad thing in this case. Let’s not bury the lede here. As pointed … Continue reading Traffic Congestion and City Design

Part of the series on space stuff. It is a good intellectual exercise to create an intuitive diagram to communicate new ideas in a compact, succinct way. Edward Tufte has written the same book several times on the topic, which is a must read for anyone who wants to learn how to effectively communicate knowledge. Some time ago I created a diagram to understand how Mars autarky would progress from local manufacturing of bulk goods to more complex parts. It was not a good diagram and upon revisiting it even I found it confusing. I’m revisiting the topic here to … Continue reading Understanding the make-buy question in a growing Mars city

Aging and death is as inescapable as taxes and leaf blowers, but why? How? Despite millennia of obsession and billions of dollars in research, we’re still far from understanding the biochemical particulars of why we age and, ideally, how to stop it. I’m the opposite of an expert on anything biological but I saw an interesting numerical feature of aging data and will discuss it here. Aging and age-related diseases are responsible for the vast majority of negative impacts on quality of life, and healthcare expenditure. The graph below charts the Gompertz-Makeham law of mortality. Retaining the annual chance of … Continue reading Numerical convergence as a model for senescence

This blog is a direct follow up of Starship Is Still Not Understood, and is part of the series on popular misconceptions in space journalism. Now available in audio form. I think it is relatively straightforward to think of cool … Continue reading Science upside for Starship

This blog is a follow up to So You Want To Start A Carbon Capture Company. In the last five months, the cadence of new entrants in this space, as well as new climate-focused funds, has only increased. This is a marked, though welcome, contrast to the now familiar dithering and lack of unified action at the international political level. Our entire civilization rests on our ability to harness ancient solar energy stored underground as reduced (i.e. not oxidized) carbon and capture the heat unleashed when we bring it into chemical equilibrium with the surface by combusting it in our … Continue reading Scaling Carbon Capture
