  1. We will see. It is going to get harder as the penetration of renewables increase. There will be more machine contrained during the windy and sunny days meaning that prices will go up to pay for these machines. Underutilised plant cost $$$$$. The fact that labour has subsidised batterys has taken customers away from paying for grid infrastructure. People can off set there whole bill meaning other people who cant afford batterys or rent accomodation have to subsidise these peoplesbills as well as the batterys. I think we will end up paying a subscription type cost like we do for phones. (after everyone is sucked in to get batterys)
  2. France will be and I would say all ready are looking at wind and solar, but they will always have their NP to do the heavy lifting. The reason they are curtailing nuclear generation is because of environmental issues that weren't thought of at the time. I would think this would not happen with their new builds. Are they really cheaper then Nuclear over 80 years, Really? Currently France exporting about 12GW with a green grid. Germany, not so much! https://world-nuclear.org/information-library/country-profiles/countries-a-f/france https://app.electricitymaps.com/map/zone/FR/72h/hourly
  3. So windfarms in city parklands? Was in Europe recently, Quite a few in Amsterdam and could see a WTG from the London Eye. The ones in Amsterdam that I saw close were 3MW machine, so reasonably large.
  4. With electricty (I'm a fan by the way) we need to remember transmission losses as well.
  5. Electric motors and converters still release heat as does anything that makes the electricity to power them. Would be interesting to see how much a WTG releases with gearboxes, muliple electric motors converters and hydraulic systems/ MWh.
  6. Do you guys really think the other partys are tied to billionaires?
  7. Do you think Albo is a leader?
  8. Never say never!
  9. Apparently doesn't matter what you promise with the current mob just say it to get voted in and then do what you want. But the sheep will still vote for them
  10. As I understand, submarines use weapons grade enrichment. Heaps of spare current reactor fuel by the time it is down blended. Sweden have recently started building underground storage as well.
  11. Interesting video on the make up of spent fuel. This bloke also has interesting videos.
  12. As far as the grid forming inverters go, I was talking about black start capability as in at Broken Hill when they had the blackout. They had all the wind and solar but the part on the inverters for black start hadn't been commissioned. It would have been a good opportunity to test it. We can store the waste, the facilities still need to be built. Again the more we do the better we will get. Meanwhile it is just sitting on site getting less dangerous every day. I enjoy this blokes videos even though he exaggerates how dangerous the long lived waste is. A uranium fuel pellet can be held in your hand with no protection. Technicians wear cotton gloves to protect the pellet from the oils on your hand. These 2 elements have half lives of millions of years as was quoted in the video. Generally the longer the half life the less dangerous it is. I wouldn't eat it though. The amount is always quoted in tonnes. A lot of the spent fuel is still U238 which weighs approx. 20 times the weight of water so the actual volume is a lot less than you would think.
  13. Decommissioning and waste disposal has been solved. It is a political and public perception problem. Most of the waste is long lived waste. Easily managed by deep geological storage or for fuel in a fast reactor. Long lived because it is not very radioactive. The deep storage completed in Finland is costing a part of a c/kWh. Having looked for an update, the 500MW test reactor in India went critical in April this year. Most of the shorter lived waste is dangerous for between 300 and 500 years depending on who you asks. Can also be stored under ground. Shorter life because it is more radioactive. If something happens on the earth that this becomes an issue, I reckon there will be other things to worry about. The big ones as far as decommissioning goes in the west are Sellafield and Hanford. These were built to supply bombmaking material during and after the war. Decommissioning would not even have been thought of. I would think new builds would be built with this in mind. and there is so little of this waste. Synchronous generation does this as a part of it design so it is essentially free. Traditional hydro does this as it is synchronous generation. Not sure about pumped hydro though. It may have inverters to allow reversing pumps etc. Not sure grid forming battery have really been proved yet. We had an opportunity in Broken Hill last year but the inverters didn't have that part commissioned I believe.
  14. You are right, India is building a lot of renewables along with their nuclear. Look at Germany as well. Lots of renewables but still have the interconnectors with the countries that have synchronous generation. The Baltic states are the same. India have also loaded fuel into a 500MW fast reactor which will lead to being able to breed fuel from Thorium and U238.(not sure how they are progresing) They are looking at this because they have limited access to Uranium. Australia isn't even looking at having any synchronous generation apart from gas for backing up the intermittents. It would be good to replace the black and brown line with Nuclear and let wind, solar and gas play with the rest of it. It wouldn't be easy, but not much is. Snap shot of Europe today as well.
