Noisy morning, pile driving nearby again, just as last week. The perks of working at home..
that put a smile on my face simpler times
(not really, I know; just for me)
I had some version of it on the PS1 in simpler times, so can relate. Actually seems like they might be done, haven't heard it for a few hours now.
getting some thunderstorms coming up. Hoping it doesn't bring the same flash floods that other storms seem to be doing atm
how much electrical energy is released globally in thunderstorms? compared to human elecrticity generation?
oooh a gigajoule in every bolt
didn't realise Back to the Future
had done their research...
that's 27 tonnes of lard per bolt
maybe we just need to install wave power generators in every underground railway station
I've read about it several weeks ago. It's not how much is generated that counts but how much we can gather. The thunderbolt is very brief and it's hard to construct infrastructure that gathers even a fraction of it. So yeah. Even though the earth is moving we can't put it onto a cogwheel...
But well... if you have an idea, go for it.
@U793EL04V funny you mention Back to the Future. Watched a documentary yesterday, originally it was supposed to be the energy from a nuclear test. It was changed to be able to stick to the budget.
Oh right, I read it here, so it's not a scientific proof: https://en.wikipedia.org/wiki/Harvesting_lightning_energy "the energy in a https://en.wikipedia.org/wiki/Thunderstorm is comparable to that of an https://en.wikipedia.org/wiki/Atomic_bomb, but trying to harvest the energy of lightning from the ground is hopeless" But it's wikipedia.
hopeless
does not sound like a scientifically calibrated term
@U793EL04V it is wikipedia, after all. And it's an interview with a PRIVATE owned company which may want to protect their newly acquired technology. And he said not "hopeless" but he said "hopeless from the ground".
I think in some Frankenstein things they use a kite to capture it? Still it seems the investment to handle the peak would be huge compared to the gain with how often it will be hit.
Something tells me that if you set up too much energy capture, the bolt will want to hit somewhere else
Maybe the idea is to use the bolt to light some treen and then use the heat to turn water to steam and finally electricity. You know, efficiency doesn't matter because thunderstorms are free!!! 😈
@U054UD60U why not just use photovoltaics then ;)
Hahahahaha
> So yeah. Even though the earth is moving we can’t put it onto a cogwheel... @invertisment_clojuria This reminds me of the concept of a Dyson Sphere, which I encountered in some sci fi novel. Fun thought experiment, and I loved the depiction in the novel.
Ah, the sphere which captures whole planet... Well I think that if this kind of sphere would be constructed just to gather lightning then we'd have some immediate environmental consequences. For lightning I imagined something less intrusive. Like a drone which flies to charge up a battery. (internet drones may be onto something here)
There's a really really good series on youtube called "Kurzgesagt – In a Nutshell". Here's a link "https://www.youtube.com/c/inanutshell/videos". They have one on building a dyson sphere:
https://www.youtube.com/c/inanutshell/search?query=dyson. Should be top hit.
Which captures a sun, right? To harvest its energy.
I’ll have to listen to those Kurzgesagt peeps at some point

Särö Västskog, Swedish west coast (less than an hour's drive south from Gothenburg). Morning!
It is a nature reserve (if that's the term). Quite a gem, if you're ever in the vicinity.
