Tennessee was good as always (back soon). Now to “the Treasure State” of Montana. Never been, looking forward to it!

We’re two weeks away and things are coming together quite nicely for the inaugural Africa Bitcoin Mining Summit in Nairobi. It’s really about miners in Africa being able to meet up in-person, learn from each other, share, and to build a community. image

Geothermal is pretty amazing energy tech. Not just the massive 200MW locations, but the small “non-viable for commercial” ones too. image

Final thoughts on this. Installing medium sized bitcoin datacentres at generation stations could solve this. Any/All of the datacentres can be switched off in seconds and the power immediately made available. It’s like an inverse peaker plant that earns money + stabilizes the grid. This is what the Chair of Kenya Power had to say (image): image View quoted note →

12 hours with no power across Kenya due to a fault at a generation site. That’s bad, but not nearly as bad as the international airport not having any power due to the backup generation there being down and flights being sent 4 hours away to South Africa. Embarrassing. image

Kazi ni kazi. The team getting to it as we build the next container. image

Back in Kenya with a thousand and one things to catch up on. And it’s cold!

Ok, that’s a wrap here in Zambia. All checked out and running. I should probably do a more in-depth write up sometime. It might be best to say that there’s a lot more that goes into a bitcoin mining site than just running miners!

A decent day. Less crazy than the last few anyway. Fully load testing all the miners against the forebay water level sensor It should be noted that a sudden switch of all machines to high efficiency/low power settings on the miners does cause a generator crash… lesson learned! Dummy pool activated. This is why we test the scenarios while on site. Anyway. Onto celebration steaks by the Zambezi at our camp!

Good news is we’ve got full connectivity. Now testing all patch cables and PDUs. But a few miners are already hashing! This bonding service makes a huge difference on dropped packets.

Sunrise over the forebay. Zambia is a beautiful country.

We’ve been able to get good signal with LTE, but it has to be about 100m away up on the forebay. The point-to-point WiFi link has had some issues, but we think we know what’s wrong and will fix that today. Gotta get these miners live. image

Give a man a free mosquito net and eat for a lifetime… or something like that. :)

Some days are long… but we got the container maneuvered into place… after about 6 hours of doing things without all the right equipment. Next is electrical and miner installation. image
