Exactly where my mind went too -
Will be curious to see the implementation!

I’m flattered, but really I just dabble in a bit of everything that catches my interest 🤓

I wouldn’t have guessed back in high school that my chemistry lessons would be making a comeback 20+ years later to try and work out carbon capture systems!

This means for one of our small ships with ~35 tonnes of CO2 emissions per day, for each day’s sailing we consume 10 tonnes of fuel and 100 tonnes of Ca(OH)2…

And are left with 135 tonnes of CaCO3.

They also said “Carbon capture is really the only thing that we can do.” so I suspect there’s some level of creative phrasing in there 🙃

Unless mistaken, going from Ca(OH)2 at 74.0927 g/mol to CaCO3 at 100.0869 g/mol is a 35% increase in mass - assuming you do actually get it perfectly dry.

Which part? The energy intensity, or the weight?

I’ll see if I can dig out my notes from when we spoke with them a while ago, I had put some numbers to the weight gain. Your article states ‘no major net gain’ which is a bit vague haha

This option has fairly low energy intensity onboard (compared with liquifying pure CO2 for example) but it does mean loading tonnes of what is essentially rock… which will get even heavier as it becomes saturated.

It’s an interesting concept.
As with many carbon capture options, it will depend on having global infrastructure to both support the shore/vessel transfer, and the local processing.

I do like this!
Miss standing on the bow with just the sea and stars, and the rush of the wind.

Especially today when our weather optimisation had predicted winds to become more favourable.

Seeing the Main Engine kW drop slightly as our WindWing kW picks up, and the ship’s speed increase, is very satisfying 🤓

Also available on Spotify and Apple Podcasts so please have a watch or listen, and share with anyone you think they might help.

(That’s practically everyone btw!)

4) simplified automations. I had some monster paths in NodeRed that can be handled far more gracefully now I know better!

Lots more of what I want to achieve can be configured in the HA UI now, no coding required. Both HA and my knowledge have improved in this since my last setup!

3) Backups. It’s embarrassing I didn’t have them more frequently… data is still there if I want to use it but I’m not importing anything into my fresh start.

HA have made backups ridiculously easy this year, including to google drive etc. for remote storage.

2) Loading devices and integrations into background ‘areas’ first.
I have some named ‘hardware’, ‘software’, ‘web services’ etc.

Then I can pull only those entities I want into actual areas like ‘kitchen’ and ‘bedroom’ to avoid clutter.

I set my friend up on HA Green a few weeks ago and that’s going strong.
Have a few key automations and it just carries on happily in the background.

My own is a bit more involved - currently at 750 entities and I’ve not added everything back yet 🤓

I’ve just been running HA OS to date - no idea how dividing up a system for something like this works haha

The intensity kicked up a notch when I started using Predbat for energy optimisation. The run time of the optimisation increases with tariff complexity. Never even made it to agile haha

The eMMC definitely can, and I have a couple of ideas I can use the micro computer for in the near future.

But at the same time giving home assistant a bit more room to breath probably isn’t a bad idea!
April 18, 2025 at 8:46 PM
It appears the little eMMC has given up.

The computer itself seems to be just fine, but it’s got nothing to run anymore 😅

Time for an upgrade to a £150 Intel NUC with a proper SSD perhaps.
