Good grief. Starlink v2 satellites are generating 32 times more radio emission than previous generations! This is totally blinding to radio telescopes and will stop us doing science in this part of the spectrum.

Fun* fact in this video: the 'disposable' vapes thrown away in Britain alone contain enough lithium batteries to make 1.2 Million e-bikes.
I've been independently powering things with vape batteries that I've rescued before seeing this video. Pull out the cell, add a cheap usb charging module and you have a fully rechargeable 3.7v power source. If you need higher voltage you can put them in series and you can even get multi-cell balancing modules for next to nothing if you want to have a few in parallel for more current.
I don't trust them for anything critical, but they're great for low-budget projects as the cells are completely free. My bike lights are all powered by them (one can run a flashing bike light for a couple of weeks' use), as well as various other things that had their batteries die, or that didn't come with rechargeable batteries.
I also only charge them somewhere flameproof, though I haven't had any issues so far.
