No. Not that mermaid.

 

[I'm a loser baby...]

No.
No two lumps of coal are unalike

Truly magical.

 

[Gary Gutful]

Amazing even, according to the Minerals Council of Australia.

So you do believe we should supply other countries? Because that kinda goes against what you said when you said "why should we supply other countries?"

no, I said why should we supply the world, as you asserted we should so we dont trash the economy

look at the problems we are experiencing with LPG, we are supplying the world and we got f**k all for our own people and the price we pay for what is mined here is ridiculous

every one is fighting over what little is left for our own market and if we supply the world with our coal we will no doubt go the same way

that said I agree with the rest of your post

 

[Twizzle]

Is it just me or did @Twizzle very clearly suggest that there were alternatives to using coal for steel production and then later distance himself from such claims?

Show of hands please.

I think you are mistaking where the power comes from, which was my point or it was supposed to be, rather then the use of raw materials (coal) for the making of steel. You cant make steel without coal, as I said we all went to high school,

there is no reason why renewables cant be used to power steel manufacturing, I'm not really sure why that is so difficult to get your head around

I am not in favour of people like Adani raping our country for tax payer dollars so they can pollute the GBR,and central Qld. Coal is a very inefficient way of producing power, its a 5 step process and the second stage, burning of the coal to make steam is very inefficient as we see a lot of energy wasted and is discharged out those huge stacks and pollute the environment

if we are going to pout money into upgrading infrastructure we should invest in hydro and renewables as hydro is dispatchable power and doesn't pollute

If energy can neither be created nor destroyed, then how do you explain hydroelectric power?

 

[Bazal]

Hydro totally wrecks ecosystems though. Even renewables can have huge environmental impacts, which is something a lot of the kind of people I was talking about before seem to miss.

But theoretically, a paddle wheel stuck halfway up a waterfall, where the water has far enough to fall after it leaves the wheel to again reach terminal velocity.... isn't that basically creating energy? Or at least creating more than you are expending?

 

[Twizzle]

mainly potential energy and some kinetic energy being converted to electrical energy,

transferred not created

wind has some acoutic issues in harmonics but generally they are located from occupied areas, but yeh, even a nice cab sav has its drawbacks, normally he next day

we dont live in a perfect world, if we did we would have beaten the Storm and wouldn't have had to play the cowpats

The wheel takes the energy from the water, then the water is still subject to gravity. It still has mass, so gravity can act on it.

Actually given gravity can act on light it theoretically doesn't even need mass. But that's more physics than I'm qualified to bullshit about

impossible to create energy, it can only be transferred from one form to another, or one form to others

the trick is to transfer it efficiently which probabaly only happens with wind and hydro

solar and coal fired suck balls as far as efficiency goes

 

[I'm a loser baby...]

Right, but if the water continues to fall doesn't it have the same potential energy? So is gravity taking the hit?

No we don't and that's my point. Everything we do impacts the environment, so it becomes about trade offs. Hydro probably is too destructive, on a large scale anyway, to be a worthwhile solution.

Realistically for Australia, solar and wind are probably the best options. Which is why there's now a billion solar panels up the road from my place. But even they have downsides. Especially if you're a bird.

EDIT I say wind and solar because unfortunately the Greens have put paid to nuclear power, which is easily the best option

 

[Twizzle]

gravity is what causes it to fall and is fixed, its is responsible for the water having potential

the water has x amount of potential based on its height, so generally the hydro plants are closer to the bottom, as it leaves the plant it may still have some potential but not much as its nearer its terminal velocity

there are other issues which determine it viability like economics of building the merkin in a dangerous environment like a waterfall, hence its all done in a sealed pipe systems behind a huge wall

So hydro is lowering the earth's gravity? Now that I think about it, that's probably why they call it 'getting high'.

Gravity is a constant result of mass. You and I have gravity, it's just miniscule compared to the moon, or a planet, or the last manatee Gary had relations with.

So no, it's not lowering gravity. Gravity is acting on the potential energy in the water and converting it to kinetic energy

solar is only about 30% efficient but it has no moving parts and cant break down and its reasonably cheap

, wind will work of a night and solar wont, they all have different aspects

problem with renewables is they are not dispatchable, they need to have their change stored, we used to have the best storage system in the world (Vernadium Radox) developed in Melbourne, sold the patent to the Japs and they have done f**k all with it, so all we can do now is pump it into the grid

 

[Twizzle]

Gravity is the moons pull on the earth. Its only relevant when discussing how potential energy works. No gravity, no potential energy.

Enter Elon Musk!

Eventually we're going to need storage of some kind anyway. Or we could shoot all the Greenies and build a couple of nuclear plants...
