Can Bitcoin help pay a firehall’s heating bill?
I put 2 Avalon Q miners to the test in a firehall garage. Two firetrucks full of water, near freezing outdoor temps, and I slept at the hall to monitor the situation

I've built a website I always wished existed: a collection of all the books written about Bitcoin.
I've found 110 of them. If I've missed any, let me know in the replies.

Ongoing experience with: @heatbit_com

its been 3 weeks since i requested a refund wtf is going on with this company

Had a little free time and a Waveshare Solar Power Manager D sitting around.
So naturally this happened. 😂☀️₿
Little solar Bitcoin desk build, designed and printed from scratch.
V1 needs a few tweaks, but I’m pretty damn happy with it.

A visualization in 15s resolution and a time span of about 18 months, plotted on a 24-hour day, of the grid demand on our Zambia community site.
(Not shown is the generation line ~500-700kW. Everything between that generation line and above the dark blue is usable by bitcoin mining)

BEHOLD THE PIZZAXE 🍕⛏️
I HAVE HARNESSED SHA-256d TO MAXIMIZE FRESHNESS.
A liquid-cooled Bitaxe GT 801 heats my pizza bag while mining bitcoin.
Not a product, just an engineer left unsupervised.
FRESH HASH. HOT CHEESE. ZERO RESTRAINT.

Every Bitcoin block ever mined has a constellation. You just couldn't see them.
betweenblocks.thesolomining.…
BETWEEN BLOCKS is something I created. It's a living portrait of the mempool, on live @mempool data. Watch transactions fight for space in the next block, then look up any block since 2009 and meet its stars.
Time delayed transactions is how we stopped ATM scammers in 2017. It works.

A small but mighty donation! $8.80 or 88 cans returned for 9942 satoshis. Added to our treasury.

JUST IN: new peer-reviewed research finds Bitcoin mining has the capacity to absorb 83% of the wind Ireland is forced to throw away, lifting wind farm revenues by 32%.
The paper is a wake-up call for grid operators, regulators and political leaders around the world whose grids are wasting large quantities of renewable energy, because the paper includes a head-to-head comparison with battery, finding 2 significant advantages, both which matter to the taxpayer.
1. No subsidy required:
"Compared with battery storage, hydrogen electrolysis, or transmission reinforcement, the co-investment is privately financed and operationally market-driven" and "...without requiring physical network upgrades or regulatory subsidy."
2. No performance degradation
"Unlike battery storage, mining incurs no round-trip efficiency losses or cycle degradation; unlike hydrogen electrolysis, it requires no downstream offtake infrastructure."
In layman's terms, this means that a battery gives back less power than it takes, and wears out with every cycle - whereas hydrogen needs a pipeline and a buyer at the far end. Bitcoin mining simply pays to use otherwise wasted power on the spot and needs nothing more after that.
Plus, Batteries, hydrogen and new wires are all paid for by the public. Bitcoin mining, uniquely, isn't.
To summarize: Together with previous papers on renewable energy monetization using Bitcoin mining, this technology is looking increasingly like the only tax-neutral way to keep renewable energy transition targets on track (or get them back on track).
The finding puts even more pressure on Ireland's neighbour, the UK, which continues to waste significant amounts of wind energy, to properly evaluate Bitcoin mining.

This paper is doubly-significant because prior studies were done on deregulated grids like ERCOT (Texas). This study shows that Bitcoin mining's benefits extend to islanded regulated grids with high renewable penetration.
The study comes at a time where Ireland is currently wasting11.4% of its available wind (source: cms.eirgrid.ie/sites/default…). Its Climate Action Plan targets <7% curtailment by 2030. But an independent estimate says it's currently going in the opposite direction, projected to increase to16% by 2030, even with storage and demand response built (source: seai.ie/sites/default/files/…).
The paper is published in Energy Economics which has an impact factor of 13.5 (top 2% of academic journals)

this is an abandoned industrial lot in Brazil.
i drew a shape on it and got back: 64 native species that would thrive there, where to buy each seedling (~$2), and a simulation of the forest it becomes by 2060.
works for any patch of land on earth. free, open source.

1351 cans/bottles/glass/cartons returned today, more than 5 different community members contributed to this block, our 12th donation. In total we got $135.1 giving us 149,478 satoshis towards our treasury and ultimately building the greenhouse. #bitcoin

Absolutamente increíble. Lo que hoy ha hecho Barcelona se recordará mucho tiempo. La Sagrada Familia, Gaudí y los que durante 140 años han creído en ello, lo merecían.
Wow cool, going to try this for our @TheSoloMiningCo ghost edition for @btcgreenhouse
Heard about zappool.org today at the @FreedomTechSum in Prague. Mixing small home miners with payments via Zap’s on Nostr.
There are others like Hydra Pool on Nostr from the @256FOUNDATION as well.
Which is bullish for continued decentralization of bitcoin mining!
