Thank you Representative Hortman

Taniel @taniel.bsky.social · Jun 14

Melissa Hortman, who was assassinated last night, was the Speaker of the Minnesota House in the 2023-2024 session, when Democrats ran the state government.

That means she had a leading role in shepherding the many landmark reforms that Dems adopted in that period—an important legacy. Brief 🧵.

You can buy the cumulative power of human minds. The same technique that was able to differentiae ourselves from our animal brethren - civilization and knowledge.

Course, plenty of knowledge is dead end...but in the right hands, in an infinite world, most probably is something for someone.

Yes, Ambri, the liquid metal battery company, is bankrupt.

If you know someone who wants to start a battery company, the #Ambri_Inc physical and IP assets are up for auction, including patents, patent apps & trademarks.

Much appreciation, i guess ill use it as mental motivation.

But copper definitely isn't down, course the US dollar collapsing doesn't help...

Battery technology and maybe batteries themselves to be limited in exports. Though one interview says it is a paperwork process to get licenses to export, how ever others have suggested these limit could be strategically implemented to affect drone warfare.

Let’s call this what it is: the President of the United States directing federal prosecution for his personal political agenda.

I stand with AG James — as we all should, for the sake of our democracy.

New York Attorney General Letitia James @newyorkstateag.bsky.social · 17h

This is nothing more than a continuation of the president’s desperate weaponization of our justice system.

I am not fearful — I am fearless.

We will fight these baseless charges aggressively, and my office will continue to fiercely protect New Yorkers and their rights..

Cool to see that the solar panels I've installed on my balcony at the beginning of last year have already produced over 1.3MWh, in just 1.5 years!

Picture of the solar panels from the outside, you see two large panels (two grids per panel) hanging from the balcony rails

Real test of my solar panels was going to be how they performed over winter.

Got my bill.

They still provided a net return to the grid.

A green solvent enables precursor phase engineering of stable formamidinium lead triiodide perovskite solar cells - Nature Communications

The use of harmful solvents to fabricate stable devices hampers the commercialization of perovskite solar cells. Here, the authors introduce a biorenewable solvent system and precursor-phase engineering to realize stable formamidinium lead triiodide-based solar cells.

Silver nearing $50/oz. from <$20 less than two years ago.

A year old, but a standard commercial module uses 8,400 mg/<0.3 oz of silver, so ~$14.80/module.

Makes recycling viable, and older module used more silver per module.

It does increase silver per watt to 2.5-3¢/W if buying on open market.

Gold is up 54% this year in the US, but a lot less wvwrywhere else because the dollar is down 11%.

With an administration pumping money and international deflation though, expect more.

New study looks into stabilizing 100% renewable energy systems over multiple bad weather years.

It concludes that the best approach is a little more overcapacity (e.g. 3.5% extra) as that is much cheaper than excess seasonal storage.
