Fascinating. I recently learned that clean creek water can be made drinkable with an RO system. The under sink variety is affordable! I intend to move to the 'edge of the grid' instead of 'off grid' and rather than digging a well, I'll be getting some of those 275g water jugs. A solar powered pump would hopefully be enough to fill it. I'm not worried about it being speedy. Then let an under-sink RO system handle making it potable. Technology is amazing.

This may actually be a good case for mechanical spinning power storage. Flywheel capacitors that can help regulate the power grid. They can be relatively cheap and can help buffer these issues out on a wind/solar farm. You could also connect them in series to stabilize things.

Over 8 min into a 14+ minute video and we still don't know the answer to the title of the video, "How long would society last during a total grid collapse"? I ended the video before making it to the end - I still don't know the answer.

One very important question is do you know JESUS CHRIST AS YOUR PERSONAL LORD AND SAVIOR?

People living less than half a mile have had material residuals in their houses that were not tested (there was one test for something that wasn't an issue), and houses and businesses are being abandoned. Wildlife has died at higher rates, the creek water has a rainbow, and people are showing higher incidences of illness. NS AFAIK has done nothing for the townspeople except oh, they set up a new city park!

Why don't they paint the rails silver or something similar to reflect some of the solar gain? Seems like a cheap way to get lower stress range, we did that with long piping runs.

was with a couple dozen cousins at our family cottages on lake erie ... fortunately, we had plenty of cold beer in coolers before the blackout occurred so we were good for the day ... great memory ...

Of all the risk and damage, the people who benefit from the dam only complained about a minor interruption in service. Those of us living in and around Oroville lived this.

999,666 views looks so funny.

It’s easier said than done. But we need engineers to utilize the powerful waves to power Hawaii

Yeah!! Guessed it! Whoo! (Hvac tech :) )

Fission reactor ?

We don't need them because they issue heat orders! 😂

Oh wow :( this is kinda sad, ... here in South Africa we've solved the same problem but used a very different system. no buckling, no metal fatigue inducing stresses, ... just a sliding joint every kilometer or so.

Very informative

Bad neighbors?

Nuclear power is the future

Here the solar charges a big DC battery and then an inverter supplies in the house and pushes to the grid. If the grid goes down, the pushing stops.

Sooooo, how do the sturgeon get through?

This is the same process with that sacrificial thing in my water heater, right?

Great video!

"just so happen i have an arcylic box in my garage full of sand to show these concepts" love all the garage tinkering. im very much the same

CIA says 2 weeks max

I like Grady, he’s a cool dude.

I lived by giant transformers that powered our town in Shaker Heights OH and heard a loud BOOM, we didnt know half the country went out of power at the time, had to use old radios with 6volt batteries to keep up with what was going on.....when it got dark...you couldnt even see in front of you.....crazy

5:45 this blew my mind

That's an incredible river model.

This video has certainly helped me relax a bit during construction delays.

I am that kinda person that looks at something and what is it and what does it do? So this really helps

So much work and so much man hours for these dam fish

i saw some issues were occurring in epoxy so i used ordinary iron oxide primer, anyone know how it does in structures ? it was all i had available and hope i did the right thing !

Lovely family dude

What about ice flows and freezing?!

They work... Well.

What if the treatment plant overflows?

What Hawaii could do to improve reliability is to have generators on barges that can be moved from one island to the next as needed. Most of Hawaii electricity comes from solar. The roof top solar makes more power than the state can use on normal days. That is why they have been some of the first who have invested in battery storage. They had battery storage thirty years ago.

Odd title for a video that only mentioned spillway gates once in a list of other things, then talked more about bridges

they need a nuclear power station

Is this a God Dam? -Beavis

Sounds Like trash under the surface and more expensiv when it needs to replaced

Fish ladders are great for getting fish up the river, but not for when they go back down…. As fish follow the main flow they usually go into the turbines ….

At last a steel with an expansion factor of Zero was developed.

When I was in college, I read a book called soil mechanics. The book was so interesting when compared to actual field itself.

Boiled one moment

Whoa! Ground News is sponsoring this?? SO COOL!!

I just want coal and cheap power! Hawaii is already low on pollution compared to anywhere else!

You should definitely do a video on horizontal drilling like we use here in the Marcellus shale in Pennsylvania. Same concept, an insane amount of technology in it now.

too much theory and blah,blah,blah. Simple people just don't understand.

Can sonic cannons used for seismic imaging or fracking have serious implications for aquifers and water flows ?

In France we're working to develop the collect of waste water and transform by a process in Gas. And then we inject again in pipeline network to supply homes with heating and cooking. Like we did the the same with farmers call biogas.
