The Way We Get Power Is About to Change Forever
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.
Inside the mind of white America
I'd have to beg to differ on America having similar Aboriginal/White conflict. IMO the divide between aboriginal/white in Canada is actually much deeper, and with a greater potential for future violence than even black/white relations in the US. The conditions on Canadian native reserves are MUCH worse than in the US. It's severe enough that the first time a Canadian is driving past an America aboriginal reserve they have to ask twice to confirm it really is one. The general state of broken down infrastructure, housing and in general is so bad it's even visibly unavoidable up here in Canada. In the US you can't tell you've gone past anything different unless something culturally relevant is posted up.
It's also made worse by systematic segregation that the reserve system in Canada creates so any seed of racism has lots of fertile ground and lacks any reference to counter balance it.
When a car is stolen is something goes missing on farms near a reserve the immediate default assumption is that someone 'aboriginal' took it. It's only made worse when more often than the statistical distribution should dictate, it actually was someone from a reserve that did it. Recently a car of young aboriginal kids pulled into a farmers yard and one of them was shot and killed. They said they had a flat and were just looking for help. The case is on going, but the courts have heard that the neighbour had already put a call in to police about a theft minutes before the shooting though. Of course, white folks on the internet made such helpful comments as suggesting the farmers mistake was 'leaving any witnesses'. It's also not just white racism against natives though, the racism against settlers(whites) amongst aboriginal populations can be just as ugly and rampant. When Canada decided to have our border crossing guards carry guns, we had to close a border crossing that was in a Mohawk reserve because they wouldn't allow it. The border station there was already riddled with bullet holes before this. If the government DID try and enforce the same law there as the rest of the border, people were going to die.
That's not a real difference. We have all that too, on top of the black/white, Mexican/white, Arab/white, non-white/white issues.
The main difference we have is reservations here have their own tribal courts instead of special treatment in normal courts. An alleged side effect of that is a white person can go to a reservation and attack a native, and never be charged because they can't get a fair trial in tribal courts and normal courts won't take a minor case from the reservation (I've never tried it myself).

What killed a federal job guarantee in 1945? Jim Crow.
Check out page 7.
"The Full Employment Bill had potential to change the prevailing system of racial and labor relations premised on the subordination of African Americans. Consequently, the bill faced opposition from business and farm lobbies, who sought to replace the bill with one that was less threatening."
Also, get a load of its details:
“all Americans able to work and seeking work have the right to useful, remunerative, regular and full-time employment. And it is the policy of the United States to assure the existence at all times of sufficient employment opportunities to enable all Americans [...] to freely exercise this right.”
That's part of what I mean when I laugh at the notion that policy proposals by Sanders/Corbyn are "radical". A federal job guarantee was accepted mainstream in 1945, yet a living wage is considered pie-in-the-sky utopian madness in 2017.
Millennial Home Buyer
Decentralization is the key. To almost everything city wise..... housing, transport, modern farming etc.
Especially with cars driving themselves soon and the interwebs.
But that will never happen when your president is a real-estate agent lol. The more people you can squeeze into cities the more Trumps buildings be worth.
Here's a thought, instead of adding $600 billion dollars to the US military budget, we could use some of that money to push broadband out to every home in the US.
When every struggling post-boom town has high speed internet, we just need to push the dinosaurs who resist "work from home" out of senior management positions in the corporate world and we'll have a migration towards the smaller, more remote communities, where property values are much lower.
It will mean that sprawl subdivisions will become the new slums...but that just provides incentive to bulldoze those warts off the map and return the lost farmland.
The paradigm shift would spark massive economic growth.
Naw...we need more tactical stealth fighters.
Kurzgesagt: Are GMOs Good or Bad?
Thank you for sharing your perspective, @MilkmanDan!
Here is a link from a farmer detailing what is in one of those license agreements, including a copy of one:
http://thefarmerslife.com/whats-in-a-monsanto-contract/
"That’s what we have to agree to in order to make use of Monsanto’s biotechnology on our farm. I don’t see anything in there that hurts my farm. Neither does Iowa farmer Dave Walton. I don’t have to buy their herbicides, and I don’t have to buy anything from them next year if I don’t want to. The biggest problem I have with seed companies is that it seems like they phase out a variety from time to time that is a really strong performer on our farm. "
Kurzgesagt: Are GMOs Good or Bad?
**EDIT**
I'm finding other sources that say that sterile "terminator seeds" are a patented technique, but that Monsanto has promised not to use it. Straight from the horse's mouth:
http://www.monsanto.com/newsviews/pages/terminator-seeds.aspx
So it appears that my info below is wrong. I will try to talk with my family and get the full story. That being said, I'll leave my original comment and the followup below unaltered.
*********
My firsthand knowledge of this stuff was from more than 10 years ago, and also when I was pretty young (early 20's). So I did some web searching to try to get updated since your question is a very interesting one:
http://web.mit.edu/demoscience/Monsanto/about.html
According to that, Monsanto is the company behind "Roundup Ready", and their corn (and other crops in the line) do use sterile "terminator seeds". It also mentions that farmers "must purchase the most recent strain of seed from Monsanto" each year.
I was never in the decision-making structure of my family farm, but I did remember that we couldn't just buy the Roundup Ready seed *once* and then hold a small amount back as seed for the next year and continue to get the benefits.
I'm not 100% sure exactly how the modification for sterility works -- I don't know if the plant will sprout if you plant the sterile seeds and just fail to produce any ears / fruit, or if it just won't germinate at all. I do remember that we had to be quite careful to fully clean out the corn grown from the GM seeds from our storage bins, and better yet to store our non-GM corn to be used for future seed in entirely different bins. That was done to make sure that we didn't end up planting any of the sterile stuff.
I'm sure that the seed dealers that sell the GM stuff really push farmers to buy and plant it every year, as hinted to in that link. But you certainly don't *have* to. On the other hand, if you go back to non-GM seed for a year or two or more, you can't use a strong herbicide like Roundup if you have an unexpected outbreak of weeds or other pest plants -- the Roundup would kill the non-GM crop along with everything else.
Basically, I don't specifically begrudge companies like Monsanto for their practices concerning these GM crops. The "terminator seeds" are controversial, but don't seem like a big deal to me. If you could buy GM seeds once and then just hold back some of your harvest for next season's seed, they'd only get your money once AND we'd probably lose the original strains. So I see that as kinda win-win, especially if you don't 100% buy into their sales department urging you to use GM seed every single year.
I don't want to sound like a shill for Monsanto -- some of their other practices are pretty shady, particularly political lobbying. But from the perspective of my family farm, the GM corn that we use was/is a real beneficial thing. Significantly less pesticide/herbicide use over time, and it allows for expanded low/no till farming. Before herbicides, tilling was one of the only ways to kill off pest plants. But, it also makes the fields lose some moisture and nutrients. Expanded farming and ubiquitous tilling was largely the cause of the "dust bowl" dirty 30's. Anyway, I'd say that a lot of good has come out of modernized techniques and technology like GM crops.
I think many people don't realize how GMOs have made farmers' lives so much easier.
I'm surprised to read what you said about your family's GM seeds being modified to be sterile though; the video states that terminator seeds were never commercialized. Since you're talking about corn, maybe it was just hybrid?
Kurzgesagt: Are GMOs Good or Bad?
Some additional notes based on growing up in a wheat / corn farming family:
My family uses GMO herbicide/pesticide-resistant corn seed (Roundup Ready). It's a tradeoff, because:
1) Roundup Ready seed is somewhat expensive, especially compared to just holding on to a small amount of your own harvested crop as next year's seed.
2) Like the video mentioned, the GM seeds we used have been modified to be sterile, so the grain they produce can't be replanted. Part of the justification for that is not wanting the GM version to intermingle with unmodified strains. But, most is pure profit motivation -- they want you to be forced to buy that GM seed. I don't really see that as nefarious, just business -- but opinions differ.
3) My family discovered that for corn, we could us the GM Roundup Ready seed roughly once every 5 years while still benefiting from drastically reduced insect / plant pests. If corn is within pollination range of another less known crop plant called milo, the plants can hybridize and produce a plant called shattercane. Shattercane is essentially worthless as a food crop, but is very hardy, and can spread and in many cases outcompete the corn or milo that you really want.
Getting rid of it was a very difficult and intensive process -- until the GM seed came along. Now if we see shattercane starting to make incursions, we can plant the GM seeds the next year and then hit the field with a herbicide that kills the shattercane. It works so well that the field remains clear of the pest plants / insects for several years after that without having to use much if any herbicides / pesticides.
4) In our situation, we found that we used way less herbicide / pesticide per year on average once we started rotating in the GM seeds once every several years. That would be close to a wash, but still likely a net savings even if we used the GM seeds every year (seed companies will try to sell it to you every year). Factor in increased crop yields because of the reduced/eliminated pests, and it is a clear win.
5) I'm sort of worried about the potential for a "superbug" effect, similar to overusing / misusing antibiotics. If farmers buy into the GM seed thing 100% and use it every year, I think it will increase the chances / rate of the pests becoming resistant to the pesticides / herbicides used. That's a long-term concern, and in my opinion doesn't even come close to outweighing the "pro" side of the GM argument (at least from the perspective of my family's farm), but it is something to think about.
Dog Feels Petting Instead of Abuse For The First Time
Yes, we must all go full vegan, for no farm animals have ever been treated well.
Dog Feels Petting Instead of Abuse For The First Time
I'm not sure I could ever stop eating meat (primarily chicken), but I understand that there is serious mistreatment and mismanagement of farm animals. I think a greater adoption in North America of CAK (controlled atmosphere killing) via something like high concentrations of nitrogen gas would be a great improvement, especially if it could be extended to pigs and cows. The old stun bolt or electric immobilization (for poultry) and throat-cut method seems so barbaric and I find it hard to believe that it doesn't result in pain.
Dog Feels Petting Instead of Abuse For The First Time
I'm trying to point out(and failing obviously lol): If we feel so bad for this poor dog, why do we turn a blind eye to farm animals that are mistreated and killed? They all feel pain and have emotional responses just the same.
We all like eating meat and butter, but is that worth the animals suffering and dying for it? (especially when there are some great alternatives. Nut butters, coconut butters, cashew spreads you name it, margarine at worst case) That's a decision for you to make. :-)
If a dog beater told you that "animals kill each other in nature all the time" would you accept that answer? Would that stop you from feeling bad for the dog?
When someone at the Yulin dog festival says "it's my tradition" or "I like the taste" do you accept that?
Then why do we make the same statements for cows? (don't worry, I remember yelling "lions tho" at vegans, so I'm not pointing fingers)
I just want to raise awareness about the horrors of animal agriculture and it's knock-on effects to the planet. And that we have a choice, and the power to change the world. We don't need to wait for governments or laws, we can make this change now, ourselves and there are no down sides, only wins.
It's just a matter of changing a few ingredients

Dogs = good
Trying to make me eat hummus instead of butter? = bad?
Idk, I don't think the two are as related as you imply. Either way, animals kill each other in nature all the time. You think if I didn't throw a lobster into a pot of water it'd die of old age? He'd probably get ripped apart slowly by a sea turtle.
^see how that doesn't sound like a conversation about abusing dogs anymore?
Post script: for the record, I believe the most humane way to kill a lobster is by driving a knife through the head quickly, NOT throwing it into the pot of water alive. I'm not for animals suffering, but I like eating meat and butter. The artery clogging is the animals paying me back. So it's all even.
