The Unreasonable Power Density of Lithium-Ion
We’re all used to it by now, but I’d just like to reflect on how insanely power-packed lithium ion batteries are, and everything that’s afforded us. I’m trying to think of a gadget, a hobby, or nearly anything in my house that’s not touched by the battery chemistry.
I’m looking at my portable wireless keyboard in front of me, with a LiPo pack inside. Oddly enough, I’m charging it with a LiPo-based power bank, simply because the cable to the nearest USB-C adapter is too short. A gaming console, cell phone, and a DSLR camera are all within arms reach and powered with lithium.
It’s not just consumer stuff either. I fly FPV quads and airplanes for fun when I can, and of course those are made entirely possible by the combination of smaller brushless DC motors and their drivers, and the high-power-density LiPo packs that power them. For field recharging, I have a huge self-made LiIon pack that can keep them all in the air all day. These days, LiPo and LiIon tech is the heart of hacker projects big and small. Heck, we even powered this year’s Hackaday Supercon badge with a LiPo that allowed it to run all weekend on a charge for many folks, where in the past swapping out AAs during the event was commonplace.
The application that still blows my mind is that we recently got a solar installation on our roof, which means a huge LiFePo battery in the basement. And while it’s one thing to power noisy little quads on the battery tech, it somehow seems another to power our entire house, for multiple hours per day, from a battery. Granted it’s not a couple of AAA cells in a little black plastic box, but it’s simply amazing to run a washing machine, the fridge, the stove, and even the heating off of what amounts to a battery pack.
Of course, I’m aware of the costs of producing the cells, both in terms of money and the environmental damage. It’s not a free lunch, and I’m looking forward to both cleaner and cheaper energy storage chemistries in the future. But for now, I’m still in awe of the many options that lithium-based battery chemistry has brought us. May your pillows remain non-spicy!

翻訳というのが軽視されすぎというのもあるかも知れないな。言語ごとに文章構成の癖とかも違うから、実際は母国語で書いてから翻訳すれば良いというものでもないよね。
例えば英語のニュースとかで、日本についての記事で“the Asian country”とか指したりしがちだと思うけど、日本語だったら「そのアジアの国」なんて書き方は翻訳でもない限りまずやらないよね（そもそもこの書き方は偏見とかをエンコードしやすそうだから個人的に好きでない）。こういうこともあって、母国語を経由するよりそのまま対象の言語で書いた方が良かったりしがちだと思っている

Asini e umani: un sardo sfida Trump per…
@anarchia
… il Nobel della pace 2026. La “bottega” ringrazia Ignazio Sanna per questo scoop. Un evento imprevisto potrebbe impedire l’assegnazione del Nobel per la pace 2026 a Donald Trump. Infatti, il fulgido astro del principale pretendente pare improvvisamente oscurato https://www.rivoluzioneanarchica.it/asini-e-umani-un-sardo-sfida-trump-per/
