TIL the shiny metal coating on top of vacuum tubes is not an X-ray shield, but a reactive coating to scavenge any remaining molecules out of the vacuum.
That sounds like a great way to attract scammers and dissuade honest people, so if it's ever been tried it must have failed spectacularly (I also searched for variations of this idea but didn't turn up anything).
It probably worked for Romans because the taxes you were allowed to collect was so much more than you had to send back to Rome that you could get rich 'honestly'. That and you had options to prove the fraud that meant the other was unlikely to try.
Of course a 1960's design isn't adapted to current weather conditions. That doesn't mean the whole technology is useless, like so many commenters imply.
Any new build can and will include cooling adapted to hotter conditions.
Hungary had the highest share of produced solar electricity of all the countries in the world 27.3%.
And even with this results nuclear energy is usefull for them and plan to build new reactors. (with help from Russia, so there may be same changes in this plan)
Starting this year, in Romania you cannot put new PV capacity online without the storage for it, is mandatory. Possibly for existing ones, but I am not sure.
Yes, absolutely colossal amounts of batteries though - what if it’s quite hot but also cloudy for 5 days in a row?
You either have to significantly oversize the PV (easier said than done, when its energy density is already not that high per m2), or have enough batteries to last for multiple days of full load. If you do the maths that’s a lot of batteries
>what if it’s quite hot but also cloudy for 5 days in a row?
The main idea is to then import power from somewhere sunny and/or windy or mountainous, using money you saved when they had the rain and you had the sun.
Batteries and other storage mechanisms will gradually reduce the need for doing so, but aiming to entirely eliminate all need for cooperation with others seems a bit paranoid.
"According to the adopted act, devices with a capacity of up to 30 kWh are exempt from any construction procedures; only reporting to the grid operator (OSD) is mandatory. Those between 30 kWh and 300 kWh in a building and 30 kWh and 2000 kWh freestanding are obliged to prepare a land development plan and make fire safety arrangements."
AFAIK the mountains are about as high as Wales? It looks like there's a 600MW storage scheme in the planning stages. That's about a third of the capacity of Wales's largest system (which is the biggest in Europe) and about twice the capacity of the second system.
It's a meaningful contribution I would have thought.
Can't speak for Hungary specifically, but the problem with flat terrain wrt hydro storage isn't just elevation difference - which can be offset with flowrate - it's the large surface area to storage and to depth ratios.
Large lake means more losses, mainly due to evaporation, but seepage is also to be expected. Now put this fact in the thread's context: water shortage/stress...
"Most of the country has an elevation of less than 200 m. Although Hungary has several moderately high ranges of mountains, those reaching heights of 300 m or more cover less than 2% of the country."
"Hydroelectricity is not prevalent in Hungary due to unsuitable geographical conditions and civil resentment. The country's capacity of hydroelectricity was 57 MWs in 2015."
It depends on the water balance.
Reservoirs would help you smooth out variability/seasonality and mitigate infrequent, short term droughts, depending on its size. They would not help with a long term drought or if you are water stressed (i.e. you simply don't have enough to meet demand). Quite the opposite, they may exasperate the issue as they consume (or lose) water themselves.
I'm fairly sure that when it's dark where I am (because I'm in the shadow cast by Earth), it's also dark in orbit above me (because it's in the shadow cast by Earth).
That math leaves out externalities when pricing gas, oil and coal. You may have heard of a few fires going on in Europe in addition to nuclear plants shutting down?
Beyond that, those resources are also the lifeline for a dictatorship in the east causing increase defense spending.
There definitely is no such thing as cheap gas, oil or coal for Europeans, all things considered
You're probably going to struggle to come up with a motive for that behaviour. It is much more likely that they simply aren't very thoughtful. Complex webs of deception in a public argument are certainly possible, but it generally relies on some group having a clear financial incentive to misdirect. That doesn't exist in the nuclear debate.
Because HN was a forum for oil executives to gather and discuss prices? Big fossil isn't in the room here. It would surprise nobody if there were 0 people in the comments who even work in a fossil fuel company.
>You're probably going to struggle to come up with a motive for that behaviour.
No, I'm not. Not in the slightest.
Number in top right go up. Monkey brain feel goooooood when that happen. Monkey brain keep doing behavior that make that happen.
> It is much more likely that they simply aren't very thoughtful.
They're plenty thoughtful. They'll contrive all sorts of arcane logic, plausibly deniable lies and witty turns of phrase (some of which are quite impressive).
What they're not is self aware (the dishonesty is a byproduct of that).
> Complex webs of deception
Those are possible but I don't think that's what's happening here.
> but it generally relies on some group having a clear financial incentive to misdirect.
Internet fanboys work for free. They have no financial incentive. Therefore we fall back to the monkey brain incentive.
Yeah I'm not sure, just identifying that subjectively, this is the impression I get. Maybe I just associate any style which is especially fluent and avoids vernacular with AI at this point.
Yep, it's astoundingly inefficient. I've been meaning to pull the code back into working memory and do the things I mention in Future Considerations, but it took long enough just to do this write-up; could be years before I get around to it.
