hi mehdi

Sup mehdi

I almost feel bad about installing 9 solar panels this summer.

Ha ! I got you Mehdi ! I knew about this heheheh.

Hi mehdi

Exactly my thought. 😂😂😂

Also lost energy due to evaporation when it is sunny...

@@stephenshumaker8444 Rain compensate evaporation and infiltration.

@@agustinruizmoreno524 Yep, in a rainy area it does! Probably won't with Hoover Dam in Nevada.

Dinorwig www.electricmountain.co.uk/Dinorwig-Power-Station is reported to manage 75%

@Claptrap Jesus Its usually used to stabilise the grid so i would say yes ineficcient, but very important and well worth it.

As the video says, if you can get money more than you lose with all things considered. It's feasible to build

Lithium ion is 80-90% efficiency, but it’s also terrible for grid level storage. Grid batteries like iron- or aluminum-air have much lower energy efficiencies, though also require much less space. Pros and cons.

Its horrible in an absolute sense but pretty good in a relative sense

Whatever you can do on the bike test, you are then allowed 5\8 of 48-minute test, for a constant 24 hours flow. You can use a local battery to supplement and local buffer peak usage.

Assuming everyone has a car connected to their house, and quality of service #smartmeters, #smartgrids exist, the local buffers, should allow a pleasant much closer to #stepladder power control model. Sort of .... no definitely very surprised and impressed that automatics now surpass fixed ration gears for fuel-efficiency. Your video mentioned dynamic power output, while also stating a single power output exists as ideal, same logic from fixed ratio gear days (i know the gears are still fixed, and i do like continuous variable more, even if there is more slippage and wear, or torque limits, in power generation, is this an issue, or would consumables be too expensive=my answer is year yes, i prefer shaft drive to belt, even if belt is a more pleasurable experience).

Didn't know that you also watch his channel I love you guys both Real engineering

@@keviloltsukru1278 I watch both channels, I love how Practical engineering focuses mostly on civic engineering, and real engineering is more about mechanical/aerospace engineering. They actually complement each other really well.

First time I’m realizing that these are two different channels.

Well university lecturers have to give you the details, which are not so fun no matter which way you spin them. He just goes over the basics which anyone could get

It's once a formula gets written down, is when the lecture always starts getting uninteresting.

@@electron2601 that is why you should study with people, and talk about interesting implementations on your "free time".

Congratulations my friend! Not only is it environmentally friendly, but it can be constructed out of materials, mostly from a hardware store. Don't think most people can build a lithium battery from scratch. Massive respect all around.

You should make a video of it. Sounds cool

It's very inefficient compared to battery 🔋

For my fellow americans, its around 984~ feet

I heard you need at least 300 m or 1000 ft to make pumped storage practical and of course a good reeervoir.

@@awhahoo lol

Hahaha , it’s a bit like filling yr car up to go on holidays, then returning to the same bowser when yr need to fill up again.

wait, where? i thought we had none. auserdem: hallo.

Pumped up lips. I had to do it hehe

Aaaall the other engineers with the pumped up machines, better run better run, outrun my innovation.

Actually you can store electricity in bottles, it is called batteries and you can buy them in any stores ;)

@@a64738 AC. vs DC.

@@hairybass480 Inverter exist... The best ones have about 10% loss in the process of converting DC to AC from 12-24 or 48V. I have a small 150W in my car for charging laptop but plan on installing full 48V system with large battery bank, solar panels (as much that can fit on the roof of my box car van) and 2000 - 3000W inverter so I have 220V AC that can run anything up to 16A :)

Hi, I'm a bait fish, I need water to exist for no reason, flush all your potable water out to sea...

@@Edwardmodos hi, I’m flint Michigan. What’s potable water again?

@@trash_mountain ouch :D

PHES systems reuse the same water over and over again - depending on the upper and lower reservoir. They require little make-up water - only for evaporation and leakage losses.

Someone with the last name Gutierréz(sp) too,

grischard? from osm! fancy seeing you here

Erik Språng I recon.

Just play it at 2x speed

Even less efficient - pumpstorage has a roundtrip efficiency of roughly 70% (or higher), P2gas so far the best lab results where ~70% - ONE Way. There exists quit a few already out in the wild, but their roundtrip efficiency is often lower than 30% even. It is one way, but one that, with the current technology, is only viable because of the extreme volatility of wind and solar as well as the unreasonable push of those technologies. Yes - unreasonable as they are so volatile that the endanger the electric power grid of whole countries and in total even increase pollution - great case study for that is germany (where they have many p2Gas facilities because of that). It is an interesting technology, but imo it should be use for energy storage but rather for energy conversion - there are applications where you do need those chemical fuels and on the long run it is a lot better for the environment to generate the gasses needed from air than pumping them out of the ground.

@@ABaumstumpf yeah

@@ABaumstumpf Wasn't Germany's emissions increase from shutting down nuclear and booting up the coal power again?

@@firstname405 Yes, significantly even so, because while wind and solar are renewable power sources, they are way too volatile and so they now have to run way more fossil-fuel-plants on standby. Most of the time not even producing energy but they need to be kept running to be able to deliver the power when needed. The nuclear power was great at providing the base-load very consistently and cheap (and still better for the environment funnily enough) Better storage methods are needed, but the governments follow the blinded Eco-groups that are driven by outrage and not facts. There is a nice article on the impact of different energy-sources done by greenpeace - despite their own numbers showing that even Chernobyl is better than Wind-power they say it is evil and should be banned...............

@@ABaumstumpf woah, that's crazy! Do you have a link for the coal plants running as back up but not providing energy? I'm aware of the benefits of nuclear energy but didn't realise they had to stoop THAT low

Yup... beautiful summer vacation area... great hunting and fishing and lots of Lake Michigan beaches. Hope to retire there some day.

I'm glad I found someone in the comments talking about the Ludington Pumped Storage Facility! I was disappointed when it wasn't mentioned in the video. My dad and I spent some vacation weekends about an hour east of there when I was younger, and one day when we were out on the beach near the Ludington pier, he pointed south along the shore at some strange structure in the distance. It looked like a giant four-legged creature standing on the shoreline. I made a lot of very wrong guesses, and he wouldn't tell me what it was. Then we got in the car and drove south, parked, and then climbed a hill for a bit. When we got to the top, I was awestruck. Nearly 3.5-square-kilometers of water, on a hill. The weird structure he had pointed out in the distance was the crane that sits on top of the outflow gantry, so that water can be drained from various depths. If you ever happen to be in the area, it is an awesome place to visit. Seeing it in person, its sheer size is almost incomprehensible.

China Japan and the US have the most PHES capacity for above 1GW sized installations.

Works great if you're on a reliably-flowing river. Can't always count on that, though.

What if we use space solar. The only prob I can think of is transmission then.

@@mohammedraheem6288 Just that pesky lil transmission kerfluffle... Haha, that's kind of a massive issue particularly considering the Earth rotates while orbiting our star, while tilted. I mean I'd be all for it, but... We aren't close to an applicable technological solution.

@Claptrap Jesus well if we can find all the materials to produce the photovoltaic panels in outer space, then we would not need to send every panel from Earth's surface.

I built a solar power plaant with molten salt storage a few years ago. A government funded billion dollar project. It's a total failure. They're declaring bankruptcy.

Fairly small cf. what one group in Australia is promoting: two hundred sites, each with 200MW and ~10 hours storage , for a grand total in Eastern Australia's "National" Electricity Market of 400,000 MWh or 400 Gigawatt hours.

Love going down to Johnson shut-ins and hiking around there. Once did the hike from Taum Sauk to the shut-ins. The scar is one of the most impressive things I've ever seen on the destructive power of water... Especially 1 billion gallons in 30 minutes according to Wikipedia. That accident is definitely one of those hindsight is 20/20 kind of things.

Yes I walked the tunnels briefly on a visit to Bath when it was under construction. An 18 wheeler could have been rolled into one.

Also very close to an ancestral family cottage on the coast which is still in the family, there is some remains of a tidal pool that was dammed off, and documents describe a waterwheel which would close off and use the seawater every time the tide went out to grind grain. So that's an oldschool example of the seawater application of the energy use.

Agreed. The Taum Sauk Mtn reservoir was extremely dangerous due to negligent engineering & operation by Ameren-Union Electric. It nearly killed the Park Ranger & his family at Johnson's Shut Ins below the break. It destoyed a natural Fen ecosystem that might never return.

I was under the impression that all other things being equal, 70% efficiency was still pretty dang good. I'm under the impression cars were like... 25%?

The efficiency for pumping up water is around 80% and 90% for power generation when letting the water flow back down. Multiplying those two numbers gets you 72%. It's way better than many alternatives to regulate the powergrid.

@@ChemistyStudent You have to look at the complete picture and 25% is the efficiency of the whole car, meaning 25% of the energy stored in the gasoline is converted into mechanical power at the wheels. Now, if you look at transmission efficiency you have to multiply the 70% with 96% squared, one for transmission to the plant and once for transmission from the plant, meaning you have a complete efficiency of around 66%. Still better than coal plants, who have a maximum electric efficiency of around 45%. Gas and Steam Combi-powerplants are a little bit better and widely used for medium to fast load regulation, they have a combined peak electric efficiency of around 60%. Thermal efficiencies are naturally higher, around 85% for coal for example.

Pumped storage develops relatively high efficiencies, partly thanks to economics of scale, specially designed components (pump-turbines, rather than machines designed specifically to be pumps or turbines, or very smooth penstocks to minimize friction losses), automated controls and operation at higher current and voltage levels (easier to overcome electrical resistance of wiring and magnetic components). If you want to know about a place that truly leverages pumped storage, look at Japan. Despite its proportionately small land area for its huge 127 million and highly industrialized population, a lot of the hydroelectric plants of Japan have nominal power ranging from 100 MW to 3,000 MW. The reality is that almost all of these big facilities are pumped storage. Given that most of the water is cycled between the upper and lower reservoir (rest lost to evaporation and leaks), the flow that can be sustained is far bigger than what can be sustained if relying only on the river discharge feeding the reservoir. This means that, conventionally, pumped storage can usually deliver peak power 8-10x greater than the power of an equivalent conventional hydro facility having the same head.

70% isn't all that low.
