The Way We Get Power Is About to Change Forever

MilkmanDan says...

No Netflix for me, and no luck on a quick search of torrents, but I'll keep my eye out for that show/series.

Many metrics to compare. Ecologically, that system sounds great for static locations with enough of an elevation gradient and reservoir areas to make it work. On the other hand it seems like the ecological damage done by constructing batteries, factories, and disposing of them is likely quite small compared to many other alternatives, particularly fossil fuels (which also have long-term scarcity concerns on top of plenty of other issues).

A major advantage of battery tech over hydro storage would be mobility. If the thing consuming energy doesn't sit in one place, hydro storage won't work. Another somewhat less significant advantage is the ability to install anywhere -- a battery farm recharged by mains and/or a solar/wind farm could be installed in places where hydro storage couldn't. And for one more item in favor of batteries, I'd wager that the land area footprint required for batteries is much smaller per kWH stored, although that might be wrong for extremely large reservoirs (ie. a hydroelectric dam, pretty much). But by the time you're getting to that large scale, the location requirements and ecological disruption are also much more extreme.

Anyway, I don't mean to pooh-pooh the idea of hydro storage -- it really does seem like a very good and ingenious idea where it would be applicable. But there's certainly room for improved battery tech, too. I don't think that we're going to get fully or even significantly weaned off of fossil fuels quite as fast as the video would have us hope for, either. Fossil fuels were the primary tool in our toolbox for a LONG time. And as the saying goes, since all we've had is that "hammer", we've started to think of everything as a nail.

There was a show, islands of the future, on Netflix now, that had a large scale demonstration and explanation of it, used to store wind energy and power an island.
Unfortunately, I don't know of a comparison with batteries with concrete numbers.
I think you hit the nail on the head with what you said about efficiency, but for large scale storage, it has to be better when you factor in the energy costs of making, replacing, and disposing batteries, even including the cost of replacing the turbines.
...and all that ignores the ecological issues, where ponds beat battery factories hands down.

The Little Mermaid 2017 - Official Trailer

poolcleaner says...

You're right but at the same time I have quite enjoyed television movies and low budget films with that special someone in the cast. For example, I thought the Amityville Horror with Patty Duke (the 4th movie, I believe) was pretty interesting, and not even despite its low budget, because of it.

Besides you're not 100% correct about how the single star drains the pool of resources. Oftentimes these stars act as investment magnets, so people are more willing to help produce the film if it has a star such as Shirley MacClaine. Look at Reservoir Dogs -- did Harvey Keitel detract or attract from the success of the film, and the long term successes of Quentin Tarrantino, Steve Buscemi, Tim Roth and Chris Penn? Like international acclaim -- for a low budget flick from a nobody.

I'm always very curious about these types of films. It requires, for me, an almost scientific, socioeconomic evaluation of the film making process to fully appreciate, or just a curiosity of film and social interactions portrayed in film and around film sets and the bureaucracy of generating the funds and jerryrigging devices to fulfill smaller budget scenarios which drive such a project as this to fruition.

I'm very interested in seeing this movie because it looks like it could actually be good and not just a thing to pan because of the limitations.

I had a film professor who wrote a couple Jean Claude Van Damme direct to DVD movies and his view of film projects was that they are nearly impossible to complete objectives that require self sacrifice and a warrior spirit to fully realize.

Films remind me of how different societies growths are based upon resource allocation, so some societies become empires and some remain scattered tribes and disparate families. Same as in film; this is like a missing link. Strange and curious to behold but human.

Besides, you don't give a fuck about mermaid movies. This is being made for kids that like mermaids lol -- I grew up watching Disney's Little Mermaid, had every word of the film memorized, but I'm certain it didn't matter that it had a better staff and bigger budget because I also had a made for tv dinosaur movie's rap song memorized and written down in phonetic child sound language.

This looks... absolutely terrible. And with that special someone in the cast, I think we all know where the majority of the budget went to.

There are now More Solar Panels than people in Australia

newtboy says...

Actually, the load shift problem has been solved. You use a dual reservoir small hydro system, pumping water uphill with surplus daytime power and generating it on demand. It takes space, but is relatively inexpensive and is essentially a near maintenance free battery that's as big as your reservoirs and pumps.

Asmo said:

Few points...

We have no options for serious load shifting to utilise all that solar power in the evenings when it would make a difference. And power companies refuse to trust it for baseload power, so they still generate what they estimate they need for base load,and pay for rapid generation to handle spikes. Most electricity generated from home solar in Aus is wasted.

Without battery backups, the best production of the day goes to the energy company for 8 cents, and we buy back power from them (generated by coal of course) at night for 36 cents. Our energy companies aren't going to pay a premium for power they really don't give a crap about.

Most panels in Aus face north/east, to generate the largest amount of energy. When most people aren't home to use it. Instead, panels should face north/west to generate the most power in the afternoon when we come home from work/fire up air conditioners/start cooking etc. And even then, the power than is generated is but a fraction of what is consumed during peak periods due to the setting sun.

Annnnd most people in Australia do not even check their systems to see if they're still doing anything... It's estimated 14% of all home solar systems are currently non-functional due to faulty panels, inverter or both.

Until the point in time comes when energy companies can create a way to load shift solar production to ensure continuity of power, or household power storage units pricing comes down enough to be viable, non industrial solar in Australia is mostly feel good propaganda.

And while a number of coal plants have closed recently, it's not due to lack of demand as solar take up reduces requirement for coal fired power... It's because the plants are not viable any more to run and owners do not want to run at a loss. Each one that closes represents a significant portion of our overall generation being lost, with no core plan for continuity (wind and solar are not being considered as a core strategy currently).

I'm all for saving the planet, but the science/facts on solar outweigh the feel goods. Perhaps instead of patting ourselves on the back, we should be thinking about a better plan.

quentin tarrantino talks about reservoir dogs 1992

kingmob says...

I love the reservoir dogs...
I was struggling to get by....working a late shift to leave the day open for job interviews.

and I watched a lot of late night television.
and when this movie came out Conan had every person in the movie on...and then I rented it.

I don't anyone quite does the ultra-violence like Quentin does...but the dialog keeps it moving.

Epic Rap Battles of History Deadpool Versus Bobba Fett

00Scud00 says...

Really? Stony silence vs Merc With the Mouth in a rap battle? Barely a contest. And considering Deadpool's mutant healing factor, you'd have to disintegrate his ass to stop him.
That mask they have on Deadpool in the video though, it looks like it has a reservoir tip.

Nuclear energy is terrible

bremnet says...

Sorry to jump the thread here; not sure if dubious is the word either, but pretty amateur and more fear mongering with no supporting data.

First, the suggestion that no more reactors should be built because people use them to aid in production of nuclear weapons. Well kids, that ship has already sailed: In June 2014, the Stockholm International Peace Research Institute reported that nine nations (United States, Russia, United Kingdom, France, China, India, Pakistan, Israel and North Korea) possessed approx. 16,300 nuclear weapons in total. So someone builds one or 10 more? Yeah, that will matter. Someone needs to read up on the concept of deterrence.

When talking about waste: "Germany has literally tons of the stuff just laying around" - well, that's just horseshit.

Regarding accidents and number of deaths due to nuclear reactors: "devastating disasters every 30 years" - devastating? Come on, people died, but compared to other sources of energy, according to the WHO, it is by far the safest. Consider:

Energy Source Mortality Rates; Deaths/yr/TWh

Coal - world average, 161
Coal - China, 278
Coal - USA, 15
Oil - 36
Natural Gas - 4
Biofuel/Biomass - 12
Peat - 12
Solar/rooftop - 0.44-0.83
Wind - 0.15
Hydro - world, 0.10
Hydro - world*, 1.4
Nuclear - 0.04

* Includes the 170,000 deaths from the failure of the Banquao Reservoir Dam in China in 1975

So, if not dubious, certainly cheap and pedantic.

Can you provide a bit more detail than that?

What is dubious? Why is it dubious? Do you have any evidence to back up what you're saying?

Reservoir No. 2 - Shade Balls

rdavis184 says...

It would be good to see some empirical studies confirming that covering the surface of a body of water with black colored balls slows evaporation.

LA Water Manager: So, covering the surface of our reservoirs with black plastic balls will slow evaporation?

Ball Company: Yes.

LA Water Manager: Good! We'll take 100 million please.

Ball Company: Thanks!

Why Tipping Should Be Banned

Brazil drought linked to Amazon deforestation - BBC News

newtboy says...

Well, that's bad and is only getting worse, but they are FAR from alone.
For instance, while the reservoir they showed looked to be about 40-50ft below full, I recently drove over Lake Shasta in N California, and it looks to be 200-250ft low! This is also due to 'climate change', which is turning what has historically been a wet rain forest into a desert.
We are already having water wars in our state. They WILL become violent eventually. Our dwindling sources of water in the North are being diverted to the far south...and somehow they pay less for our water than WE do! WTF?!?
And we are quickly draining aquifers nation wide, making it harder and harder to drill a well IF you are allowed to.
And insanely, where fresh water is not becoming scarce, we seem to be intentionally contaminating it so it's unusable, both above and below ground.
Just don't fool yourselves into thinking this is only a third world problem...it is not. First worlders use MORE water than those in the third world.

The world's most beautiful sustainable font

MilkmanDan says...

The tank mods are added by retailers and print shops. You're right about how the system works -- the lines run from the big tanks and are inserted through a hole drilled into the carts small reservoir.

One issue with that is that most cartridges have a software page count that is used to tell you that the ink is running low / empty after a certain number of prints. So, along with the tank install, most shops will put in an aftermarket chip or PCB that resets or bypasses that counter.

For the other question, I think that Thailand still relies on printed documents more than in the US, but it is going down. I undoubtedly have a somewhat skewed opinion on things since I am a teacher, though. I teach 18 different classes of roughly 40 kids once a week, with a worksheet or some other printout being used nearly every week -- so I probably burn 700+ pages each week through my school's copy machines. Then I teach smaller private classes at home, with maybe 100 or so pages a week on my own printer(s). I have one inkjet with those tanks installed, 2 mono lasers, and 1 color laser... So yeah, I probably am a much heavier user of printed stuff than your average person.

Fairbs said:

Who is adding the tanks to the printer? The people selling them to retailers, the retailer, or is it a DIY? I'm guessing the lines connect to the cartridges in the printer and just kind of keep them full? Or do they tap directly into where the print cartridge connect to the heads? I think it's cool. Thanks for sharing.

Another question is do people in Thailand have a need for lots of printing? I'm in the U.S. and would say that personally, my printing needs have gone down 90% say over the last 10 years. At home, I print maybe 5 pages a month.
