Florian- I like the prompting of this premise to think of conditions that haven’t thought of and haven’t existed before. The large scale blackout could end so many different ways. Stunningly interesting writing. Thanks-

https://hackaday.io/project/177716-the-femtotx-motherboard-standard/discussion-20017 solar powerable phones and laptops can be developed. Companies and universities could develop them but they fall on deaf ears for 4 years whenever I ask them about it.

Interesting, thanks. Though, I am a bit unsure how much those would in general. I don't think it would make sense to replace all the hardware the currently maintains our infrastructure with such devices. Private citizens might get some use out of solar powered devices, but if you own a house, it probably is the better solution to put some solar power on your roof.

Sorry, you have not done enough research in solar. A cell phone is not practical if it's power source is tethered to a rooftop. people are mobile. No one is saying hardware needs to be replaced in a cell phone. Our society has been programmed to converge tens of hardware, such as film cameras, analog watches onto a single hardware with lots of antennas - the cell phone. This is like having a wearable- Samsung Galaxy Watch that supplements the android or iOS ecosystem cell. It requires technological deconvergence to conceptualize. I wrote a post in 2022 about it: https://drive.google.com/file/d/1r63w_AZi0myfbrHzgzBZSHz2TrVRBPkq/view?usp=sharing

The infrastructure you're referring to does not require replacing 4g towers and 5g. The reason more bandwidth is needed for modern phones is because they require so much html/JavaScript and media. In an emergency, an SOS text message is 160 characters or 1.2KB. That can be sent on an IoT modem that transmits, while consuming a few milliwatts. That doesn't require a rooftop solar. A fast 90s cell phone that can make calls might only need an 4kbps codec to have clear sounding voice. also, when Steve Jobs built his Apple I in 1977, it was considered portable. The 1984 Macintosh had a handle. Compared to the PDP-7, it was portable.

You can consider this a portable solar panel, because I did the math. I designed the power consumption to work under the average sunlight a tiny postage stamp can collect, with a buffer of 24-48 hrs. The chip consumes 1mA and the hybrid capacitors charge quickly up to 90mAh, which is 80+ hours. 40 if the screen uses just 1mA and is frequently on.

This idea was actually suggested by an OLPC developer as early as 2011: https://github.com/EI2030/Low-power-E-Paper-OS?tab=readme-ov-file#origins-of-this-project---to-my-best-recollection-and-occasionally-updated-as-recently-done-here
