Building Ultra Cheap Energy Storage for Solar PV

Solar still needs storage cheap enough to move energy between seasons. I have been working on a startup to do this for the last two years.

Possible competition for Bitcoin mining heat reuse... If they can make this as cheap as they want it to be, mining might not be able to compete due to capital costs.

Possibly the highest elevation deployment of a naval mine:

Libre Relay v29.1rc2 is now available:

GitHub - petertodd/bitcoin at libre-relay-v29.1rc2

Bitcoin integration/staging tree. Contribute to petertodd/bitcoin development by creating an account on GitHub.

The main thing notable here is Bitcoin Core v29.1rc2 merged the lowering of the minimum relay fee-rates. So Libre Relay has that too. sub-1sat/vB summer! ⛱️ Interestingly in testing this, I manually checked propagation of a bunch of sub-1sat/vB transactions. Looks like I'm not the only one running Libre Relay nodes with sub-1sat/vB! Not just Libre Relay either. Lots of nodes seem to be doing this.

Some videos from inside Russia and occupied Ukraine showing the massive lines for fuel. Ukraine's campaign against Russian refineries and other oil infrastructure is becoming successful enough that fuel prices in Russia are rising and gas stations are rationing it. In some places you need Russian government approval to buy gasoline; ordinary civilians can't get it legally at any price. It's not hard. Russia's wars end when their economy is collapsed and they can't afford to fight.

“Peace must be lasting. Not like it was years ago, when Ukraine was forced to give up Crimea and part of our East—part of Donbas—and Putin simply used it as a springboard for a new attack. Or when Ukraine was given so called “security guarantees” in 1994, but they didn't work.” - Zelenskyy A rare example of low time preference thinking in politics. Trump is high time preference: he wants "peace" now. But it will inevitably result in a bigger war later. The only way to actually achieve a lasting peace is to actually win.

Russia Blocks Voice Calls on WhatsApp and Telegram

Russia’s grip on foreign tech tightens one feature at a time.

Russia just blocked voice calls on WhatsApp and Telegram. Notice how this is happening now, after a decade of war invading Ukraine. The latest in a long list of Russian invasions. Russia doesn't need to hide the realities of the war from its population: Russian culture is all for theft, rape, and murder. It's a popular war. Hell, Russian telegram is full of Russian units bragging about their drone strikes on Ukrainian civilians. What Russia needs to hide is the fact that they're gradually losing. Just this year Ukraine estimates that military strikes on the Russian economy have already cost them 4% of GDP. Not enough. But combined with all the other costs of war, their economy is in bad shape and there is no path to things getting better without coercing Ukraine into surrender. _That_ is what Russians care about. And we need to be doing a lot more to destroy Russia's economy and impoverish that psychopathic society. Killing Russians and blowing up their infrastructure means they can't kill you.

Lukoil oil reservoirs under drone in Ukhta, Komi region of Russia. 1700km from Ukraine: Amazing work. Apparently these drones are of a type not previously seen; I certainly don't recognize them. The wings look like they're designed for very long endurance: As always, the most likely path to a durable peace will be to cause Russia's economy to collapse, and keep it that way. If they can't pay for war, war won't happen. Starving men don't fight very effectively.
