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.

Making Solar Panels With A Particle Accelerator

The Only Handheld Printer You'll Ever Need

Asmo says...

Yup, so instead of using the ink carts, you can use a laser printer + all the various types of adhesive stock you need, then you need to make sure the serial numbers you're carrying out match the items you're applying them to, deal with waste etc...

There's being a devil's advocate and then there's just being a douche...

Why is attaching an ink jet head to a hand scanner from the 90's special? call me when they stop robbing you blind with ink refill prices.

Trump Is Under Spiritual Attack Because from Demons

Drachen_Jager says...

So, just fount out, Paula White, who is considered to be Trump's "spiritual advisor" used to run a church in Orlando where most of the congregants were poor and black.

She demanded they tithe at a really high level, sometimes insisting they give a whole month's salary. Other times she'd encourage them to donate jewelery, watches, anything of value they had on them. Afterwards she'd go through the collected items and pick out the ones she liked for herself.

She's not Christian, she's the Antichrist.

Top 10 Most Viewed YouTube Videos of All Time

MilkmanDan says...

Hmm. Trends among my Thai high school students seem to be excellent predictors of YouTube views. Despacito is too new, and Bailando in a language that they have no exposure to, but other than those two every single item on that list is pretty commonly mentioned in my classes. Even Masha and the Bear, which I knew nothing about myself.

Grandpas Smoking Weed for the First Time

bobknight33 says...

Being 55 / non smoker this vape thing has passed me by so I got to ask.

Why is a Vape better than a pipe/ bong?

Why does this PAX Vape have different temp settings? For a smother smoke or for different items to vape like weed or hash or such?

enoch (Member Profile)

radx says...

Remember Scott Ritter? Arms inspector, made the rounds with Seymour Hersh about a decade ago with "Target Iran", when the Bush administration was in a very bellicose posture vis-a-vis Iran.

Interesting guy, often amongst the first to call out attempts to fabricate a casus belli on Middle Eastern nations.

He had a go at the NSA document supposedly leaked by Leigh Winner. Check it out: Leaked NSA Report Short on Facts, Proves Little in ‘Russiagate’ Case

"In many ways, the rush to blame Russia for attempting to undermine American democracy by meddling in our election system has become a self-fulfilling prophesy. The damage done to the credibility of our democratic institutions as a result of the politicized congressional proceedings has been incalculable, and by all accounts the worst is yet to come.

The Russians barely had to lift a finger—the wounds derived from this political maelstrom have all been self-inflicted. The fact that the mainstream media have been unable to accurately report on the issue only underscores the depths to which institutions and agencies will fall to deride and destroy that which they detest and abhor, namely President Trump."

Purple Mattress Sues Over These 4 Safety Questions

RFlagg says...

Skimming through things there, things start becoming fishy. He's a social media specialist, and certainly mis-represents the lawsuit in his videos, and given he had a ghostbed email address at one point, seems to indicate a rather comfortable relationship with GB (who carefully worded the point on the email issue, leaving it open to admit that the guy did have an email with them, just doesn't presently).

At the same time, I think there is some valid concern over the powder, which I'd guess is to help release it from the mold and aid in keeping it from sticking while rolled. It'll be interesting to see some more independent lab reports than the ones we've seen so far. Also, how much of said powder actually gets out if you, like most people, don't rip off the sock and cover (aside to occasionally wash the cover)? I understand micro-beads can be unsafe to inhale, but in typical use, how much gets from the bed into the air compared to other items used on a daily basis gets in the air?

Also, not sure the Streisand Effect is going on, as Purple was really well known before. Almost every mattress commercial I've seen on the Internet has been for Purple. So I don't think this is spreading their brand... unless this about spreading his brand, in which case it could be.

Okay, so I started going on about the Streisand Effect and jumped subjects to some comments in the Reddit thread about people who've never heard of Purple, then back to the effect. I'll blame that on the fact I was running late for work.

Anyhow, as to said effect, given that Purple isn't suing because he asked about the safety issues, but is instead being sued for not disclosing his relationship with a competitor, I don't know if it applies. Now it probably is bringing far more attention to the plastic beads than otherwise would be there. Now he however is being exposed for his relationships with GhostBed, and lots of questions are being raised about him, which is why I said it might apply to him.

Meanwhile, as I noted in the original paragraph, some people are saying they never heard of Purple, so I was doubting this spreads the brand, nor improves GhostBed's standing.

I had more, but I can't recall all I was going to say as the comment system crashed beyond the point I could come back and edit.

Fixperts - A Button Fastener for 82 year old Tom

bremnet says...

I continue to be amused by the long lines of "inventors" of new gadgets, gizmos and things that go bing that are very simply re-discovering items that already exist. Case in point, the button hook, the button loop, the fastener loop or other names as it was known being rediscovered here. The original button hook, serving the same purpose as this device, was patented in 1851, with many variants following. Give yourself a pat on the back kids, and don't forget to pick up your trophy.

How we feel about modern art most of the time

yellowc says...

You're probably looking for "Contemporary Art" but this piece might well be "Modern" by definition.

Anyway read this book: https://www.amazon.com/Million-Stuffed-Shark-Economics-Contemporary/dp/0230620590

Spoiler Alert: Rich people scamming other rich people who then scam other rich people later. It's a cycle of perpetuating false value because unless you're the very last person ever to hold the item, it benefits everyone to keep the false value alive.

The nuisances allude me as I read this book quite some time ago but it's fairly interesting.

Ending Free Speech-Elizabeth Warren Silenced In Senate

dannym3141 says...

It's that balance between decent people and arseholes - it's always favourable to the arseholes.

In politics or any serious consideration, if an opportunist cheats there will be a small scandal - but it's to be expected of them, time passes and eventually they're credited for their ingenuity and resourcefulness. If a decent person cheats once, it can be held against them forever, a lifelong symbol of moral bankruptcy.

That's the difference between an arsehole and a decent person. Both types of people have some kind of moral balance, with "good" on one side of the see-saw and "bad" on the other side. The problem is, arseholes move the pivot closer to the "good" side when they're talking about someone virtuous - any bad counts double.

Before i get accused of insulting some group or other, the left and right and centre all have arseholes, it applies to every group. If someone wants to say that I'm biased, and "arseholes" say the exact same thing about me, only i'm the arsehole. Well i can certainly consider that, but if we were to search through all news items in the western world to see how the 'virtuous' are held to account compared to the 'non-virtuous', does anyone doubt which way that would go? For whatever agreed definition of virtuous.

I think it's about time the left started fighting dirty, personally. Go ahead and punch a nazi - i won't criticise you for violence. The little bastard wouldn't care if one of his mates punched me.

If something bad happens to them, they want you to moralise. If something bad happens to you, lol you're a fucking snowflake.

But at this point I think we're too deep in the shit to expect to get out without getting a little dirty.

Running the Numbers - Chris Jordan on Colbert Report

Irish People Taste Test Weird American Food

Phreezdryd says...

It would be interesting to know what regions of the U.S. consume these odd food items I've not heard of before. Where is the PB&M sandwich popular?

Is this a negligent or accidental discharge of a gun?

harlequinn says...

That's not true either. Following their directions doesn't mean you won't be negligent. Not following their direction doesn't mean you are negligent. You're conflating things. Each situation needs to be judged on it's own merits.

Removing safety features is not negligence unless you make the firearm unsafe. None of my firearms have a firing pin block from the factory. They're all safe firearms. My triggers have been lightened - they're still safe firearms. I've seen triggers lightened so much that they are unsafe. As before, each instance is judged on it's own merits.

I'll soon finish my mechanical engineering degree (and don't you know it, I'm looking for a job in firearm designing), so I do know a little about this stuff. Whilst with the proper equipment you can detect crack propagation or premature wear, this is not done on consumer products like firearms. That's why I wrote "this sort of item". Unless you're going to spend more money than the firearm is worth trying to detect cracks, you won't know it has cracked until you visually identify it.

Sure proper cleaning and gun inspection is part of having a safe, well functioning firearm. But don't fool yourself into thinking it's an aeroplane or space shuttle in inspections. Go ask your local gunsmith - the best one you can find - how many times he's done x-ray diffraction on a firearm for preventative maintenance. Chances are he's going to say zero.

Spend 5 seconds on google and I know you will find multiple videos of factory condition firearms discharging unintentionally. You'll also find recall information affecting millions of firearms - firearms at risk of unintentional discharge.

I should have qualified "much". More or less than 2500 rounds a year?

newtboy said:

You're only obliged to follow directions if you don't want to be negligent.
No injury does not mean no negligence. Not following safety instructions is negligent, as is removing safety features, why you do it or the fact that others are also negligent does not erase the negligence.
You can certainly identify wear patterns and or cracks before this type of discharge occurs in 99.9999999% of cases. Proper cleaning and inspections are part of gun safety.
Not lately, but in the past, yes. I've never seen an unmodified gun fire unintentionally, but I have seen poorly modified guns 'misfire' on many occasions.

Is this a negligent or accidental discharge of a gun?

harlequinn says...

You're not obliged under any circumstances to follow manufacturers warnings or instructions. They are liability limiting instructions (they are for the manufacturers safety against being sued).

Firing pin safety blocks and other "don't sue me" "safety" features are often disabled in competition guns. When something safely fails and nobody is in danger then no negligence has occurred. If you don't get it fixed after the failure then you're negligent at that point.

You don't know if it was a (preventative) maintenance issue. Faulty parts aren't a preventative maintenance issue in this sort of item (since you can't identify a fault until something like this happens - that's when you know it's faulty).

Do you shoot much?

newtboy said:

Because he ignored the manufacturers warnings/instructions AND disabled a safety feature, I can certainly say he was negligent. I can't be certain that negligence was the cause of the discharge, but I can be almost certain.
As to the 'it worked for 1000 rounds' argument...maintenance is 100% the owners responsibility.
