I think that is a bit of a mis-direct. We don't need that now, but we do need to develop it. There are plenty of electricity sources that provide enough for industry (plenty of hydro as a simple example).
The chemical processes require research and subsequent change, but removing thermal coal and just using coking coal is a massive reduction in coal usage. Maybe that is ok to get us over the hump. There is a lot of research into direct reduced iron, which is an example of removing coal from that particular process. It is not impossible, but currently maybe not too easy.
Me too! And with a Jonsbo N4. I'm going something like the perfect home media server, with proxmox, mergerfs and snapraid.
Then I'll run any containers locally for things like media serving.
Now I need to start collecting disks, I'm going to start with 8tb ones.
Have fun!
