I find you need to look at a lot of news sites and sort the wheat from the chaff including Sky and the abc

Uranium is also available in seawater. More of it as rivers erode the earth and dump it in the sea. technology exists to extract it.

Except we need to drive 80km to use public transport in my case. Have been in rural Europe a couple of times in the last few years, pretty well public transport on any sealed road, even in the back blocks. Trains as well between city's for very reasonable prices. A$58 Warsaw to Berlin. Makes the whole comparing the price of petrol between Europe and Australia like comparing apples and oranges. Same with CO2 emissions when it comes to transport.

I was thinking of a small generator powered by a 13 hp honda so probably on 5 KVA. while they seem heave, so are the batterys Ianthe car making the whole car heavy so 100kg would be a smaller % than it would be in an IC car. It would only be for a couple of times a year and I was talking about relatively flat going like heading to Alice Springs from Adelaide.

The inverter is used for speed control. They use pulse width modulation to control the amount of current that goes into the motor. uses a square wave. I think the speed control on cordless power tool use the same system. Something that would be cool would be a towbar mount like they do for motorbikes for a 10KW generator to run while you are driving to extend your range for that 1 or 2 time a year when you need it. Could use it for blackouts or your business in other times of the year. 10kW running for 3 hours would give an extra 100 km plus?

Not to sure. Would depend on max demand of inverter. Looks as if motors in a tesla may be liquid cooled as well. Quick google found this info. https://www.evcreate.com/using-tesla-thermal-management-system-parts/ . Looks like the Pipestral electric plane also has liquid cooling for the inverter. WTG's also have large radiators for converter cooling.

There is a cooling system for the inverter

It seems the governments all over the world are pushing for universal EV use almost immediately. This is what I am saying. By all means do a transition but we need to do it at a pace that is not going to cause the country to go broke and cause undue hardship for its citizens. There is all this pressure(82% 2030, 100% 2050) which is costing a lot of money and making it hard for people to maintain an acceptable way of life. By the way, there is no way we will be at 82% in less than 5 years.

We are rushing, 82% by 2030. We need to remember the first 30% is extremely easy. Just throw it on the grid, still enough inertia to compensate for it, all the other generators just need to wind back a little to accommodate it. Now we are getting up a bit it is going to get a lot harder, a lot more expensive. We need storage syn cons, transmission. There is a lot more that happens to get electricity to the consumer than you would think. It is a very finely balanced machine with lots of components. Bluescope is also asking for a hand out from the government to help. Tasmania is importing 447MW at the moment(https://aemo.com.au/energy-systems/electricity/national-electricity-market-nem/data-nem/data-dashboard-nem), so to say they are 100%renewable is a bit misleading. Same as the ACT saying they are 100% renewable when they get/buy some of that from Hornesdale in SA while being next to all the thermal generation in NSW. SA than goes to say it is 70 something % renewables, double dipping the same energy. You are right about the other country's. If they all tried to clean up their grids in a steady sustainable way, we all would make quite a contribution, but it doesn't seem to be happening. We are cutting of our noses to spite our faces. Like I said, transition by all means, but do it so the poorer in the community don't suffer. The battery subsidy is a direct tax on the people that can't afford batterys and the way industry is happening we are going to have more people unemployed and those of us that can afford it are going to pay more tax to help them.

My take is if we try to go as fast as we are with a transition, power is going to get really expensive. More people are going to make big decisions whether they eat or keep warm at night. Blue scope steel CEO has commented on the power prices in Australia. There goes more jobs for people to make that decision. By all means transition away to a more green grid but for crying out load, do it sustainably. A 1.5% of global emissions, what we do here is going to make no difference, especially with China and India's emissions still rising. You can't blame them as they are developing their economy's like every other first world country has. As we know China are installing a lot of renewables and nuclear and are seriously developing new nuclear. Looks like a heap of solar tripped off first after a transformer blew in spain. https://wattclarity.com.au/articles/2025/06/18june-ree-report-spanishblackout/ By the way, I like electric cars a lot and would own one if I was a bit closer to Adelaide. If I was within 80km of the city it would be a no brainer. Just on them as charging stations increase, a lot of work is going to be needed with suppling them. If you have a 10 place 100KW station, That is a MW of demand which means a large cable to feed it and possibly a transformer. I realise the power output of the charger can be dialed down as load increases but are people going to accept that when they thought there car would be charged in half an hour , it is actually going to take 2.

Having worked for a renewable company for over 10 years and now working at a synchronous plant I know a bit but some people aren't interested in information they may not agree with.

But not reliable though. ho hum

So we make it someone else's problem. a bit selfish and we have better environmental and HSE practices than some other country's that supply us as well.

we probably could know if we had the will to develop our own resources.

some figures on what it would take to power a large tractor on batterys
