📢📢📢 OpenAir joins 350+ companies and organizations from across the CDR sector to call for a method-neutral EU #CRCF 🇪🇺🇪🇺🇪🇺 docs.google.com/document/d/1…

I have been investigating the fine art of dishing out a wooden chair seat for comfort today, and made discoveries that can be readily condensed into a, imho miraculously easy formula. So here goes:...

quite a lot of captured CO2 can go into concrete. Maybe a cement (powder) producer is not able to tap into that method directly, but policy shifts will open it up. There are already several US states with low-embodied-carbon concrete laws creating markets for this purpose.

My rainwater collection begins with a first-flush and debris removal tank, but it is not ideal; all the water flows through it and in a big rain it can stay stirred up. So it has debris and because it is necessarily open to the roof this means some bugs in there. The outlet to the storage tank is wrapped with three layers of...

has anyone here ever experimented with an “electromagnetic” pump? If the pumped liquid is conductive and the piping is enclosed in a coil (think solenoid), and a current is passed across the fluid near the coil, then the magnetic field made by the coil should attract the fluid passing the transverse current (causing it to...

This is a bit tangential, but it is a well-framed commentary which applies when we think about CDR....

tldr several BILLION tons per year by 2050! Roughly equivalent to the total mass of all the cars in the world - every year.

Net Zero is when the bathtub quits overflowing, CDR is how we mop up the water and pump out the flooded basement.

These EG4 batteries from Signature Solar look like a pretty good deal to me; $265/kWh according to their calculation. I paid a little over $500/kWh for some 12V form-factor lithium batteries at the start of the year and thought those were a reasonable price.

Today’s adventure: a couple of rainy days caused low battery levels, but not too low I thought - still 30% or so; these are lithium batteries and can deep cycle. They are “smart” batteries and if one is full in series, none can charge further - so they should all be at the same charge level all the time. But a couple had...

The prospects for seaweed to be a key CDR method are still largely unknown. More investigation!
