Isn't OpenCV mostly developed/funded by Intel?
voqv · 2 years ago
Yes, same impression here. I remember trying to get some documentation fixes into the codebase and felt like it all got shelved because the Intel team didn't see those things as necessary. Some community PRs/fixes just went stale like that too. Kind of now hard to merge that in my head that they now need to crowdfund.

I tried searching this strange string of nouns but was met with some strange results.

> You can see here [1] that on a time frame of 2000 to 2022 Germany is yet to replace reduction of nuclear generation (Kernkraft) with renewables

Which is another misrepresentation of statistics given that we use less electricity today than 20 years ago.

See this page for "all varieties" of the same graphs. Generally coal is on a downward trajectory, except the blip for the Covid years.

I'm not sure at which one of those graphs I should be looking at. The gross power consumption one seems to refute your own claim. The total gross electricity usage of Germany in 1990 was 551 Twh, 587 twh in 2003 and is currently around 550 Twh. Current expectations is that usage will grow to 650 Twh in 2030 and to 750+ Twh in 2050.

Your comment is wrong and malicious and looking at the data proves you wrong.

Using lignite only slowed the reduction of coal, nuclear was almost completely replaced by renewables.

Just selecting 2023 as a timeframe isn't good data.

You can see here [1] that on a time frame of 2000 to 2022 Germany is yet to replace reduction of nuclear generation (Kernkraft) with renewables. Construction of renewables in 2023 has only accelerated 50% relative to 2022 [2].

Sure, there's plenty of reasons not to build nuclear. Firstly, it's not cheap compared to modern solar and that trend is likely to continue. Secondly, it's not a responsive source of electricity - so you can't modulate the output easily. Thirdly, it takes a long time to bring on line, especially the more modern reactors have been prone to massive delays with an EPR reactor in Finland being over a decade late and Hinkley Point C in the UK, and Flamanville in France both being massively late, massively over budget and still unfinished. Fourthly, as we found last year, during heat waves rivers can run dry causing a shortage of water to cool the plants forcing them to go offline.

I'm not saying there's no benefit to Nuclear, there definitely is, and it should be part of the mix, but it's not a replacement for a decent investment in Solar.

Only if you omit cost of energy storage infrastructure and grid upgrades necessary for VRE.

Repeated often by nuclear critics even though there's evidence out there of German nuclear modulating load within 24 hours.

French powerplants did not go offline last summer, a few of them that lack sufficient cooling tower infrastructure had to eject hotter than usual water into rivers.

In Germany, the main function of LNG long term will be to smooth the transition of households from burning gas for heating to using heat pumps. As LNG is expensive, people who can will switch sooner than later. Also, rolling out heat pumps is going to take a long time and some people will be dependent on gas for as long as that is going to take.

A secondary role for LNG is to power gas peaker plants when renewables fall short. Mainly this can be done with existing gas plants. There's very little need for building more of those. Also, coal plants remain popular for this. Before the war the plan was replacing coal with gas plants. With current gas prices, that plan is out of the window and we're now looking at increased speed of the rollout of wind, solar, and batteries instead.

Germany's steel and chemistry sector require large amounts of natural gas. In general, natural gas (currently LNG) was also to smooth a transition towards green hydrogen, the plan being to build infrastructure that can burn/store/use both, as explicitly stated by Federal ministries/agencies.

> that plan is out of the window

There hasn't been officially confirmed, soon there will be a report called "Power plant strategy 2026" that will give a better outlook as to what is gonna happen this decade.

Germany has an overabundance of hills. Most places do. But pumped storage is just one of many options

Modern batteries do not burn. Teslas do.

> an overabundance of hills.

That's not sufficient for pumped storage at scale, but Germany is mostly focusing on hydrogen for now.

Germany can has and will very well be building hydrogen and compressed air storage.
voqv · 3 years ago
Well they certainly say they will, not sure about the rest.

Not if fusion would cost orders of magnitude more than storage.

"All the problems associated with" what? Modern batteries don't burst into flame. Anyway the overwhelming bulk of storage is not and will not be chemical batteries.

> "All the problems associated with" what?

Economic challenges of quickly building grid-scale battery storage , battery production for the entire globe, NIMBY's etc.

> Modern batteries don't burst into flame

they literally do

> the overwhelming bulk of storage is not batteries

Well overwhelming bulk is a high bar and storage is geography dependent. Germany f.e. can't build as much pumped storage as Australia and Australia built a large amount of battery storage vs PSH.

Related, so I'd like to give a shout out to the guys who made meta-tegra[1] possible so that I don't have to use NVidia's garbage software, which barely resembles something you get out of a proper SBC.

Just curious, what problems of L4T does Yocto solve? Except for the ones mentioned here[0] ?
