This last part of our XXL Lysimeter Experiment is about plumbing, and it's not glamorous: keeping measurements trustworthy over years is harder than the chemistry itself. Our on-site rain gauge under-caught by nearly half against the official station. Anchor to an official reference, always.

A soil-CO₂ sensor sounds like the ultimate shortcut. Weathering consumes CO₂, so bury a probe and read carbon removal straight out of the ground. Part 5 of our XXL Lysimeter Experiment shows why that's not how it works, and what these sensors are actually good for instead.

Alkalinity is the number we actually care about, and it's slow and expensive: pump the leachate, ship it to a lab, titrate. Part 4 of our XXL Lysimeter Experiment asks a more practical question: can a sensor buried in the soil, logging continuously, stand in for that lab work?

Part 2 of our XXL Lysimeter Experiment left the leachate data flat. Part 3 turns to the buried sensors, and the picture changes.

Does more basalt mean more CO₂ removal? Our XXL Lysimeter Experiment says: not so fast. The intuition is a straight line. Spread twice as much rock, remove twice as much carbon. Over 1,400 days of our XXL Lysimeter Experiment, that line does not hold.

1,400 days. Four winters. Twenty pots of basalt-amended soil. That's our XXL Lysimeter Experiment, and the treated pots removed no more CO₂ than the untreated controls.

Enhanced rock weathering has a problem that doesn't get talked about enough. It's not the science. The science works. It's that finding the right fields is slow and expensive, and verifying that the rock did its job can eat up nearly half of total project costs.

Remy: Working in shared Google Docs with Claude made easy

Almost everything I write these days is written together with other people, in shared Google Docs — reports, papers, blog drafts. And for months there was one collaborator who couldn’t get in…

Wastewater treatment plants produce CO₂ continuously — inside enclosed, monitored reactors — as a natural byproduct of breaking down organic waste. CREW Carbon uses that process to remove carbon instead of releasing it.

What is the most important job of a CEO? I get asked this a lot. Here's my answer, after 20 years running Paessler:

In a desperate attempt to get my first AI agent to run reliably I tried to make it self-optimizing (after fighting with its unreliability for 6 weeks). I wrote a 10 page document (code name "Magna Carta") describing what the agent should and should not do.

Sixty years ago when we wanted to tell computers what we wanted them to do, we wrote machine code: literal CPU instructions. Then came BASIC. Then C, Java or Pascal (compiled code). Then Python and JavaScript (interpreted script languages).

Last week, DVNE — the German Association for Negative Emissions — chose our greenhouse for their CDR Experience Tour. I was proud to give the welcome talk to our visitors, and we're publishing it now for everyone who couldn't be there.

The speaker slides of the Carbon Drawdown Symposium (day 1) are now available on the event website: events.carbon-drawdown.de/p/symposium See the individual agenda items of the first day.

The first day of the Carbon Drawdown Symposium is over. We heard about sophisticated scientific measurements and got a lot of new insights, including some new questions. Thanks to all speakers!!! 50 people were in the room, more than 240 people watched the presentations online.

Tomorrow we open the dataset. I've been working with this data long enough to know which findings I think will be straightforward and which ones will generate real debate.
