I think we need to upgrade our Kbots to Adv kbots, start building a few fission reactors, maybe a few clocked ones to so we can build them in populated places without people seeing them, maybe build a grogoth for some shits and giggles _________________ https://www.halfdonethings.com/

Nuclear fusion is the only plausible answer to long term energy demands. Solar thermal might do it with vanadium redox batteries for storage but it wont lead to a "tech level 2" society i don't think.
How long would it take to completely replace all of our fossil fuel needs with nuclear power? What would be the cost of these nuclear stations?
Water could be split into hydrogen and oxygen and used to power a fuel cell in cars. Petrol stations could be modified for this purpose.
I would assume the spent nuclear fuel could go back to the mines when the mine site has finished it's usefulness.
One day a better and cleaner power source will come along to replace nuclear, but until that day, I think that is the only available option. _________________ So even the rain that falls isn't actually going to fill our dams and our river systems

The by product of a fusion reactor is helium.
Which by the way is a non-renewable resource of increasing scarcity.
Nobody as yet has built a fusion reactor, ITER is under construction but they are going to take 50 years to do anything useful with it.
With regards fission Australia has 28 coal fired power stations as far as I'm aware and something like 60% of the worlds uranium.
Hydrogen is an energy transport medium, you don't mine it anywhere and electrolysis of water currently uses assloads more power than is available in the end products. _________________ Mechanical engineers build weapons, civil engineers build targets

"However, an exclusive Newspoll survey has found many Australians want the Government to act immediately to phase out coal-fired electricity stations.
Some 86 per cent of Australians want action on emissions within the next three years according to the Newspoll commissioned by Greenpeace.
It found 77 per cent wanted coal-fired power stations phased out by 2010. And 73 per cent wanted coal exports capped or reduced in the same period."
What would people be prepared to pay for this? If this meant the price of energy such as petrol and electricity doubled, would people still want to cut emissions? If industry moved from Australia to other nations where they could still pollute, would Australia want this? If this meant that grocery prices were to double or triple, would people still want this?
Are people prepared to pay for emission reduction? _________________ So even the rain that falls isn't actually going to fill our dams and our river systems

So the majority of Australians want to cap or limit our top commodity export? Coal exports are worth around $22 billion dollars last year which means it is equal to 19% of all exports from Australia.
Australia is always made out to be the bad guy of global warming because we are the worlds top producer of coal. This means Australia is the top producer of greenhouse gasses and CO2 emissions according to people like Greenpeace.
While I agree that a solution needs to be found people need to remember the economic impact these changes will have and not just environmental. _________________ Get Some!!!

Are people prepared to pay the ultimate price, when it's too late?
So would you be prepared to pay any price required to reduce greenhouse gas emissions by 25 - 40% of 1990 levels by 2020? Would you count any price too high? _________________ So even the rain that falls isn't actually going to fill our dams and our river systems

Like anything you pay for, is it worth the cost? Could you put a price on you grand children's future?
It might suck paying for it now, but hey, it might just be worth it when in 100 years we still have a liveable planet maybe _________________ https://www.halfdonethings.com/

If we cant go outside and food is rearly hard to grow think of how much that will also cost.
