Today you can already get 51.2 V, 16 kWh batteries complete with balancer and BMS from a European supplier for 1200 € (1400 US$): https://www.nkon.nl/novat/nkon-ess-eco-s-51-2v-16-1kwh-thuis...

And the nice thing is, prices will only get lower. They also have a 32.15kWh system for €3500,- which is insane.

But these new amazing AI image generators lets you just say "It wasn't me, it is an AI fake". Long term they will seriously devalue blackmail material.

I read a scifi novel where they invented a wormhole that only light could pass through but it could be used as a camera that could go anywhere and eventually anytime and there was absolutely no way to block it. So some people adapted to this fact by not wearing clothes anymore.

The light of other days, by Arthur C. Clarke and Stephen Baxter. Really cool book.

EV can grid cooperate without adding charge/discharge cycles. You just intelligently schedule the charging.

This is how most Time-of-Use metering already works. The driver sets a minimum battery percentage to charge immediately (eg 40% range, enough to reach the local hospital), and then schedule a time when the car should be fully charged (eg 80% by 7AM). The software just Does The Right Thing, using the same prediction and bidding algorithms as stationary batteries.

The search term is "V1G" (a cheeky reference to unidirectional V2G).

Indeed. I live in The Netherlands and use the Jedlix app to schedule charging, which works in this way. The grid operator can use this to selectively create or shed load in a specific area, which helps to stabilize the grid. Really nifty.

Ha, never knew the Dutch word 'stoep' had an English equivalent in 'stoop'!

This is a side project I started nearly 2 months ago: an online PDF converter at https://quicklypdf.com. Over time, I’ve made various improvements, but I’m still looking for feedback and new users.

I’m aware there are many similar tools (e.g., smallpdf, ilovepdf) and competition is tough, but here’s what makes https://quicklypdf.com stand out:

1. Simplicity: No email sign-up, no user account needed. Just upload and convert.

2. Unlimited and Free: Unlike some services that require subscriptions or have daily limits, https://quicklypdf.com allows unlimited conversions, 100% free of charge.

3. High-Quality Output: Despite being free and straightforward, the conversion quality is intended to match or exceed that of paid alternatives.

4. Privacy-Focused: Uploaded files are deleted from the server within one hour for privacy. Additionally, certain features (like PDF merging or converting images to PDF) run locally in your browser—no upload needed—so you can even use them offline once the page is loaded.

I’d love any suggestions or feedback you might have. If you need an online PDF converter, please give https://quicklypdf.com a try. Thank you!

I do like the about, privacy policy and terms and contions sections of the site :)

I'm reading here on local news there were multiple construction vehicles on the bridge when it collapsed.
SirFredman · 2 years ago
You can see the construction vehicles on the bridge on te right of the container ship, they are standing still and are running flashing lights. And they go down into the river ...

Oh yeah, this will work out great.

Elon designed it himself, didn't he?

He also designed the windshield wiper of doom. Which is ridiculous as well.

I've been using this app for a few weeks now and it is awesome, it really makes you aware of the amount of plumage in the area. Highly recommended!
