@knowak In objective terms, even Gazprom hasn't done as much to increase fossil gas share in world's energy mix as Greenpeace did 🤷 They say "necessary evil" but at the end of the day fossil gas goes brrrr directly as result of their lobbying.

GrapheneOS developer now seems to be running around on Twitter and threatening people with unspecified "response" when they post any less than ecstatic comments about his project.

Around half year ago I engaged in a discussion with him on Matrix, after which he quite unexpectedly deleted all my comments and kicked me out of the channel.

Today I had the (doubtful) pleasure of blocking him after he came to my DM with a long rant in response to an one-line comment...

🤷

@knowak The background is that if countries like Germany weren't shutting down their *existing* and fully operational nuclear power plants since 2010, the question of whether fossil gas is "less evil" wouldn't even arise. The only reason why they need to consider fossil gas is because they're losing the energy output as result of nuclear power plant closures and renewables cannot replace them.

@knowak True, and fossil gas produces ~50% of the CO2 per kWh as compared to coal.

The point is however that Greenpeace prefers energy source that produces 170 gCO2eq/kWh over one that produces 12 gCO2eq/kWh and does so entirely for ideological and anti-scientific reasons, while still pretending as if decarbonisation was important for them.

@freemo @2ck

100% agreed with the former postulate and this is partly captured by surface power density and GHG emissions because both indicators are calculated for life cycle, which includes mining, operations and decommissioning, each stage producing waste. Indirect, but I think it's strongly correlated.

@freemo @2ck

And when they become visible people suddenly start protesting against wind and PV farms simply because they are noisy and take vast amount of space, much larger than any other power plants.

I think a honest comparison of energy sources today should be only done based on the best estimation of the following parameters:

* lifecycle surface power density
* lifecycle greenhouse gas emissions
* capacity factor
* levelized cost of energy (but not top priority)

@freemo @2ck

> obviously is miniscule

This is a tempting heuristic, but nothing is obvious in the energy industry.

The reason is we're now comparing terawatt-scale nuclear and fossil installations with megawatt-scale PV and wind installations.

While issues such as air pollution or coal ash are widely visible at the terawatt scale - because of the scale - they only start becoming visible for the emerging technologies.

@freemo @2ck

In such case some PV panels certainly count as "toxic waste" when large PV farms were abandoned and contaminated ground with cadmium specifically

And a large gearbox filled with a few hundreds of liters of gearbox fluid that needs to be replaced and recycled.

> regular old waste here, not toxic waste

Define toxic :)

@freemo @2ck

We need to look at lifecycle outputs, just as with CO2. This article for example models material inputs for theoretical PV, wind and battery scenarios and the required increases in metal supplies (=which means in mining) are quite shocking. This is purely because of very low surface power density and capacity factor of both energy sources and cannot be improved significantly by technology improvements.

@2ck @freemo

I absolutely believe we should be investing in PV and any other low-carbon technologies.

My critique is primarily targeted at the attitude of some proponents of PV and wind who always assume the best case, highest efficiency and zero waste from their preferred technology while assuming the worst case scenario and total disaster for alternatives they dislike.

But engineering doesn't work this way...

@freemo @2ck

Actually, I missed a number of replies in completely unrelated threads - they just didn't appear in notifications - so just wondering if this isn't a more widespread problem with the Mastodon instance.

O właśnie, cenzura Internetu, karalność obrażania urzędników państwowych - chyba takie pomysły tez się pojawiały. To już 100% kalka z Rosji. Natomiast ogólna pogarda dla praworządności to już akurat endemiczna cecha polskiej kultury prawnej, tak samo było za SLD i PO, więc PiS tu niczym nie odstaje (poza tym, że nazywa się "Prawo i Sprawiedliwość" :)

@lukaso666 No bo prawda jest taka, że 90% publicystów i politologów w Polsce ma głęboko wywalone na wszystko co się dzieje na wschodzie, więc moim zdaniem nie są nawet w stanie takiej analogii zauważyć.

@lukaso666 Nie wiem czy to jest jakaś bezpośrednia inspiracja czy po prostu cyniczne adaptowanie "technologii politycznych" wypracowanych przez sąsiada. W warunkach polskich jest to średnio skuteczne (Polaków ciężko zastraszyć, inny poziom ekonomiczny no i UE) ale ma tragiczny wpływ na zaufanie społeczne. To idioci, tym sposobem doprowadzą konflikt polsko-polski do takiego stopnia, że skończy się jakąś nową Targowicą.

@lukaso666

To już było zauważalne od dawna - oni robili w 100% to samo co Putin po 1999, a przynajmniej próbowali w tych ramach, na które pozwalało im członkostwo Polski w UE. Wymiar sprawiedliwości, TK, kontrola nad mediami publicznymi i zamiana ich w agresywną maszynę propagandową - to wszystko są dokładnie kroki Putina do zbudowania "wertikału własti".

One of UK's two nuclear fusion reactors - MAST tokamak - is going first plasma today after massive upgrade as part of UK research project into fusion energy. Sadly no presence on Mastodon so best watching this on Twitter https://twitter.com/UKAEAofficial

LetsEncrypt recently reiterated the need for setting TLSA records for all of their certificates, including backup ones, not just the current X3. Here you can find convenient cheat-sheet with ready-to-use DNS records and appropriate hashes:
