I believe we've seen this article before? And my comments made then I won't repeat. I'll have more to say on the topic of energy, later.

The Australian government should support that hydro scheme.
By the time it is ready Australia will have realised that solar and
wind will never supply 100% x 100% electricity.
We will have run out of money trying to make it work.
A connection to PNG Hydro would be a life saver for both PNG & Aus.
The rule is for reliable electricity a wide geographical area is
essential unless you have total nuclear supply.

Andrew Forest is not a fool. And one can understand why he would back such a project, given the cost of land, housing and energy here. I believe Twiggy might carry the load there himself with an eye on the production of hydrogen? The estuary site is almost perfect for such a project?

And housing and land costs don't reflect Australia where they have risen through the roof in a massive bubble due to burst when interest rates rise as they must, given the debt we now carry, most of it created to support recurrent spending? And by a truly asinine government propping up its election prospects and its base. Not assisted by the albatross around its neck we know as the National Party and its coal loving ("highly moral") Christian leader?

But assisted by a lacklustre labor party completely out of step with public sentiment and still maintaining a no nuclear power stance, in spite of a 57% support for the same, in the general populous.

It'll probably call an early election in view of rising unemployment rates? All while never ever telling lies to the public while in office! And we all of us believe every word and promise uttered by coal-fired Ozzie pollies, don't we!?

I think Hydrogen is going to be another fizzer like airships. They thought that was the way to go and ignored so many drawbacks. This is the same as this Hydro project when every politician is looking to stripe us and Mr Forrest too! Just because he is successful with one iron ore project does not show an infallible judgement never mind good judgement.
I just want no Government money involved. If it is so clever you blokes buy shares and take the hit yourselves.

Why is Jeffery Young still here ? Shouldn't he be in PNG sorting things out ? Does he admit that Whitlam's involvement up there was the root cause of their problems today as it is here ?

Australia has no obligation to support a billionaire's schemes in a foreign country. We are are stuffing up our own energy, and scandalously subbing the same billionaire in a crackpot hydrogen production scheme which will blow up in all our faces, economically and, very possibly, literally.

Without question, hydrogen will be an exportable fuel of the future.

As will be, raw energy, piped via undersea, graphite cored cables. Graphene being both a superconductor and is 200 times stronger than steel!

But, particularly energy created by the burning of nuclear waste, burnt in MSR technology, where the possible margins will be huge, even at prices as low as 1 cent PKWH delivered. Using unspent fuel we're paid annual millions to take!

And as we burn then reburn it. Reduce the half-life to just three hundred years. With the tiny waste component around five per cent and eminently suitable as long-life batteries for unmanned space projects that end up in the sun or burn up with reentry.

Can anyone believe, any power reticulating authority would choose a much more expensive alternative, given the foregoing raw energy choice!?

I get that some folk don't want Twiggy to succeed! Given that could kill most if not all coal sales around the globe? And an outstanding brilliant result!
Alan B.

Cheap hydrogen would also support a local green steel industry and should Twiggy decide that's where he is going? That could generate enough billions from export sales to the world to more than pay for the hydro project!

And while I don't support committing taxpayer funds to support a foreign energy project, would continence some support for any domestic, jobs creating, green steel export project!

Given for every one dollar committed, there'd be at least two and a half returned to the economy via the usual economic flow-on factor!

The question on hydrogen is can it be cheap ?
My understanding is that the thermo dynamic rule is that when energy
is changed from one form to another there is a loss.
From a very hazy memory with electrolysis, ie electricity to hydrogen,
the loss is 30%. Is that correct ?
So we start with a 30%, or whatever it is, loss and then have
transport and all other losses in whatever the application intended.

Is all the hydrogen push just to avoid saying nuclear ?

Why is Jeffrey Young still here ?
Oops, that should of course be Jeffrey Wall. Why does Jeffrey not live in PNG where he could practise what he preaches for others to do ? Could it be that he was part of the crowd that steered PNG to where it is now ?

Yes, most energy conversions like electricity to hydrogen include some loss. Converting hydrogen to electricity in a fuel cell, as perfect as can be managed using current technology e.g., incorporates a 20% loss.

However, using my patent-pending method, the 80% recovery can be doubled through the same hydrogen production electrolysis mode to around 160%, with the additional 50%-60% channelled off to batteries or whatever.

I'll sell those rights rather than patent myself, given a patent is now the very best way to ensure somebody steals it. No names no pack drill but some nations are notorious for the blatant theft of other folks intellectual property. And I know you know who I mean.

Given the very best life expectancy to date of inoperable brain cancer, is 7 years from diagnosis, the statistical average, just 14 months. And given I've had six and a half birthdays since. Those who want it need to act with an offer too good to refuse, (50+ mill) save the new method/intellectual property be buried with me!

I require at least fifty mill to work on a vehicle that uses all the power produced to propel the vehicle forward. rather than spin flywheels or electric motors.

In fact, it could power VLT planes that use solid-state circuitry and electricity only. And where one could spend that aforementioned increase in hydrogen production in fuel cells, as the inexhaustible power source.

And way above the pay grades of all posters? So, I won't try to explain further except to the ultimate buyers, except to say. The science stacks up!

Once I've proven the new hydrogen production paradigm and the new propulsion system, both will be available exclusively to the west!
