Clean energy for Australia: the elegant solution : Comments

By Tom Biegler, published 13/1/2025

Long ago, in high school maths, I was taught about the value of 'elegant solutions'. A correct answer might be good; an elegant correct one is better.

I wonder what happens to the floor mounted battery when an EV comes down hard on a sharp rock. Also creek crosssings where the vehicle is submerged say half a metre. That other form of energy storage pumped hydro went from $2bn to $12bn in the case of Snowy 2 so nuclear is not unique in cost overruns.

My fear is that the public will warm to nuclear when it is getting too late to replace coal. It's hard to see just 7 sites housing 35GW of generation i.e. averaging 5GW per site. It's not just EVs adding to electricity demand but population growth, data centres, desalination and synfuel for planes and farm machinery. The clean energy shortage will hit us like a brick wall.

I would like just one single example of "clean energy" if someone could post a link to it please !

One where no oil is required to either produce or use. Coal has thick smoke that will eventually clear itself. Aluminium, plastic,carbon fibre, fibreglass etc are most definitely not clean & in the long run way more polluting than coal or Diesel..
If people are so worried about emission then they should adapt a less demanding lifestyle !
To waffle on about clean energy is as stupid & ignorant as humans get !
As it stands, present clean energy is part of the dirtiest & most polluting ways to produce power.

Clean energy along with sustainable development are both oxymorons....

"Nuclear energy is the elegant solution to cutting carbon emissions. It should have been adopted as soon as it was clear that coal generation was headed for closure. It's too late for that now. But the solution that was adopted is failing and not working as claimed. Steps should immediately begin to enable that first decision to be reversed. It's certainly not too late."

The energy problem is not actually an energy problem.
It's an 'incompetent leadership' problem, borne from politicians who get paid to constantly disagree with each other and achieve nothing except make things worse and cost us all a fortune in the process.

If you can fix that problem, fixing the energy problem would be simple.

"The energy problem" is a follow on affect of the overpopulation problem.
Much as is the housing crisis.

"The energy problem" isn't an energy problem. Only idiotic people view it that way !

A- Kudos Ateday- I agree.

Nuclear seems to be the only option until Inertial Confinement Fusion becomes available. But modular reactors appear safer due to lifecycle containment. Over time it might be possible to miniaturize fusion for cars.

We probably don't have enough Lithium in the world and batteries are something like 10x less energy dense than gasoline.

Maybe installing electromagnets in roads will help with the recharge time and enable smaller batteries (or perhaps supercapacitors or Hydrogen fuel cells). Definitely an expensive problematic solution.

If we could mine CO2 from the atmosphere for gasoline we wouldn't need to replace the car infrastructure. Recycle/ Reuse/ Reduce.

Offroad applications will probably always require petrol.

If we don't need to rely as much on the mideast for oil it will have geopolitical benefits

Apparently, BMW have made some interesting progress with Hydrogen engines. 4x4 Zeppelin cars anyone perhaps ?
The electric car could work ok within Suburbia but for interstate driving & boating & farm machinery etc. I think it'd be wiser to back Hydrogen rather than the pollution driving batteries !

Electric cares are pushed by those who already made them but can't sell them to get their investment back.
Germany is already having huge problems with windfarms. And, America ? Geez, just read the following from someone in LA;
The devastating Los Angeles fires were entirely the fault of Climate Change.
1. If only Climate Change hadn’t failed to clear the undergrowth.
2. If only Climate Change hadn’t failed to perform controlled burns around residential estates before the fire season started.
3. If only Climate Change hadn’t failed to build the water reservoirs that Los Angeles residents voted for in a referendum about ten years ago.
4. If only Climate Change hadn’t cut the fire department’s budget by millions of dollars just months before the fires started.
5. If only Climate Change hadn’t forgotten to ensure fire hydrants around Los Angeles could actually pump water.
6. If only Climate Change hadn’t stopped the Los Angeles Fire Department from hiring firefighters based on merit.
7. If only Climate Change hadn’t fired more than 100 firefighters for not taking the experimental Covid vaccine.
8. If only Climate Change hadn’t allowed arsonists to walk around lighting fires.
9. If only we could find this Climate Change person and arrest him.

It's interesting that the Californian Fire Officer said that the most important thing in the fire service is diversity, not fighting fires. Maybe that's why the fires are so bad.

Canem Malum,
The real worry is the panel that selected this Fire chief. The Woke movement has contributed to the mayhem modern society has morphed into ! The sooner we get a form of national Service the more chance we give our survival !
