OT: Batteries for the grid - cost

Oh PLEASE

That is absolute DRIVEL. everybody knows exactly what happened in Chernobyl.There was no explosion. It caught fire. Its core melted down, there was no secondary containment. End of.

Yes precisely, why don't people read it?

Yes, the efficiency of energy hydrogen storage is low. The benefit is that you can store a lot of energy for a reasonable time.

Don't be more stupid than you were born

None of that invalidates what I said.

Energy return on windmills is not enough to build more windmills and keep society going as well

You cant build windmill blades except with epoxy resin, and polystyrene foam - from oil drilling. You can't build steel towers without smelting iron ore using coal and you cant make the millions of tonnes of concrete for the bases without burning natural gas or coal.

If you try to using other methods, the energy requirements render it unsustainable.

No, you are just a 'concern troll'.

Everyone knows it blew up because of a runaway nuclear reaction. It is quite clear that it could have gone prompt critical. It is quite clear that prompt critical can cause nuclear explosions.

I think you will find that the hydrogen molecule is smaller than the helium atom.

Id id NOT blow up!

No, it could NOT have.

It is quite clear

Of course, in nuclear weapons, but it requires extremely close proximity of a lot of weapons grade material which the moment it starts to fission melts and drips away. That's why it has to be slammed together with a conventional explosive.

That is the whole reason behind how reactors - even chernobyl - are designed.

And the whole reason why we have what is called 'weapons grade' fissile material. because it needs to be that pure to explode. In a reactor it simply is not

Mostly because it was used for domestic lighting and cooking using appliances that didn't have safety thermocouples to prevent 'leakage'.

It blew its top and spread nasty stuff over a wide immediate area. The fire was secondary. End of.

Reactors use enriched uranium, i.e., 3% U235 and the rest U238. Bombs use weapons-grade which is enriched to some high %-age like 80%. The Manhattan Project was all about that enrichment, using centrifuges to spin uranium hexaflouride (just as the Iranians are trying now).

As the article says, there was a steam explosion followed by a fire. The heat for the steam explosion came from the (by then) uncontrolled reaction, made worse by an unfortunate design error in the control rods. Whether you call that a "nuclear explosion" or not is a matter of sematics.

Point of information here, it did for several millennia.

Not at our standard of living of course, nor our population density.

Seems to be stored at about 50 bar from the gas:cavern volume ratio.

OTOH only 1 bar from the claimed mass.

Which is one point and no, it didn't.

Our main source of energy was burning *wood*.

And the windmills then did not have concrete copper and iron in them

Perhaps I should have said 'wind turbine'...

A site worth monitoring, there have been days around a month or so ago there was sod all wind around the UK and the North sea Europe even...

Course we can line up old Boris and get him to start spouting bollix watts that worth in GW terms;?....

They can argue all the s**te they like if we're to go no or low carbon then we just have to have nuclear;

All to be done by fickle wind?.

Come on really?..

Well as long as you can generate enough "surplus! power to do it of course!...

Yes, of course. It is a huge undertaking, it is why we would need offshore wind, the concrete requirement is vast. The additional generation power we need for heating is vast. The additional generation to allow inefficient energy storage for windless periods is vast.

I've spent a lot of my professional life polishing turds. Clients come up with stupid ideas and after the event I find myself employed to help make them work. I think wind is a turd compared to nuclear, I'm just discussing how it *might* be made to work.

Yes, and there was a firewood crisis in 16th century England, prompting the move to coal.
