"It's complicated".

Many of the masterpiece films were filmed on 70mm which is about 4x the size of 35mm, plus better emulsion with a tighter grain.

So if we take your 4K number for a normal film and 4x it and double that for scanning we're waiting for 32K to master it digitally.

We're going to need faster storage!

Why ask why you need it?

Ever see a Jumbotron in 1080p? It's ridiculous.

I can totally see a wall-sized screen being useful for many businesses. Walk to one area, read what's there, move to another area to read something else. Analysts, factories, hospitals, military, theme parks, etc.

They already are doing this with walls of a dozen different screens, with that many video cards, cables, power supplies.

Or complex video splitters, muxers/demuxers, etc.

When they scale to 24K there will be customers too.

I'll be happy with low-cost 8K when all that hits the market.

Did you look at the map in the link?

Yes. It shows selected locations. It does not show "most of the world".

It shows >80% of the time for most locations around the world

Ah, not a native English speaker. When we say "24/7", it means 100% of the time, not 80%.

Quoting you:

Numerous studies have shown that if you combine solar PV with batteries you can have 24/7/365 power ...

...

... even in the far north latitudes (where wind can easily make up the difference).

The only significant north latitude shown the map was Birmingham, which was 62%, not ">80%".

Comment Re:Better on a boat than in someone's garage (Score 2, Interesting) 137

There's a retired couple in my town who had to tell everybody how virtuous they were to save the planet with their EV's and then their Volkswagen burned down their 1800's barn while charging, destroying the other EV and almost burned down their house (flame damage but saved by FD).

Billows of black smoke for half a day.

I have similar concerns with my solar batteries and need to figure something out.

Comment Re:You Proably would not notice for Petrol Pumps (Score 1) 159

Of course, many gas stations actually have these things called "employees" and sometimes they will put clearly-visible somethings (like a cone) at a downed pump. I see that very rarely, though.

So you do see them! ;-) That's what I was talking about. Yes, the broken rate is probably not quite as high as it is for chargers because pumps have been around for over a century so we have had time to really optimize the design. However, when you are going to a location with 4 chargers and one is broken and the other three are in use you really notice it because you have to wait 30 minutes or so to be able to charge. If that happened at a petrol station you'd just wait a few minutes and use the next free pump without thinking anything of it.

Did you read the text in your link?

01...On an average day in a sunny city like Las Vegas...
02 It is possible to get 97% of the way to constant solar electricity every hour of every day of the year (24/365) in the sunniest cities.
03 The economics are great in sunny cities

It is repeating what I just said: in the optimum location.

Depends on where they're made. Yeah, if your panels are manufactured in China, it's highly likely that there was a lot of pollution generate.

No, not even in China. Silicon array technology is way down the learning curve; they know how to neutralize the waste products (hint: neutralize HF with NaOH), and the process doesn't really produce toxic waste.

...
the greenies would want you to believe as they always base the calcs over the rated 20-year lifespan of a panel. And yeah, decent panels will give you 20 years of service.. But who the hell keeps panels for 20 years?

Pretty much everybody. You get a 20 to 25 year warranty on most solar arrays, and as much as a 40 year warranty on some of the top of the line arrays. Nobody throws them out after ten years; it makes no sense.

Comment Little toxic waste from solar array manufacturing (Score 1) 126

So called "green" tech like solar panels actually do produce vast quantities of incredibly toxic waste at every stage of their lifecycle that we have no viable way to deal with, unlike nuclear.

Incorrect. This is misinformation fed to you by think-tanks funded by the fossil fuel industry (and sometimes by paid nuclear-power lobbyists). The vast majority of solar arrays are single-crystal silicon, and the raw materials are sand, aluminum, and glass. None of these produce vast quantities of "incredibly toxic" waste to make or to recycle.

If you look at any of these claims that making solar arrays produces toxic waste, and drill down into what the solar array industry actually does, you'll find that all these reports on "OMG! Toxic waste!" are for processes that aren't actually used.
