  1. NBN recommendation

    Sometimes this doesn't exist - if you had an Optus mobile they'd bundle your broadband at $20 less per month. No such bundles with NBN, however.
  2. Liddell ironically was the site of a few clean coal innovations. We tried very hard to get viable cost estimates for carbon capture. Really really hard. Even firm project timelines were difficult. Capture was a first preference because it allowed coal to be used for energy streams other than pure combustion. Every time we looked at combustion to drive a thermal generator the emissions treatment costs became prohibitive. Baseload specialist would say - correctly - that for the current market a $/kWh metric isn't completely viable when considering grid reliability, but it did make the investment in 'well-treated' coal difficult, as the firms you'd ask for finance would have their own people pointing (usually then) to the falling cost of wind energy. High efficiency combustion is a possible avenue though really, I've not seen a quote. Ever. Maybe it doesn't exist, maybe (and more likely) no one's been game enough to ask. Stating an intention to invest in coal generation in the current political climate needs a strong argument. The LCOE quotations from overseas plants are high, this doesn't necessarily mean it'd be so here. It's a bigger risk that new tech and market rule changes might render such a thing less relevant/financially viable. Say it was 12c/kWh out of a HELE coal plant, this would be high against wind, PV etc but would it necessarily be bad? It'd not put prices through the roof, but they'd certainly be up a little on the wholesale median (we'd have less costly 'spikes'). Really depends on policy moving forwards. Note this isn't the same as supporting coal for the sheer sake of coal.

  4. In Melbourne. I try - and don't always succeed - to give a decently wide berth to how we might come across online. It's difficult to judge character with any great accuracy. Honestly that we're here is enough and those I've met in person on SNA are each nice people, and all bar one drank beer. There are a ton I've met through this thread that do and have worked in the energy indutry - you may be another - poking and prodding suits me just fine. My day job (for better or worse) is currently in the industry, and I've learnt more on SNA on a variety of matters salient to energy than I have in many industry forums. I don't think anyone here's a minnow - whether customer colleague or collaborator all are important. I may come across as direct though when I write to the effect of 'do you know what coal actually costs' rest assured I mean it. I don't think a superfast coal withdrawal is smart and I don't think the Left has all the answers either. There is no policy approach in Australia for Australia that isn't significantly flawed right now. We're trying to move energy forwards with no nuclear, with limited hydro (mainland) and at vastly reduced coal... this is something that hasn't been attempted anywhere else in the world. A few of us did our heads in a few jobs ago on trying to make coal cleaner and more affordable (as it suited our employer) and failed miserably. If things have changed I'd love to hear it. If you'd prefer to PM, do so.
  5. NBN recommendation

    Got an ABN you can use? Their business accounts cost the same, service is much, much better. On their 100/40 business and it's rock solid.
  6. It's not quite so hard to do a little research and work out what coal actually costs, rather than post stuff like this (which you've done a few times now): People actually research this stuff, quote on this work, invest in it etc daily. For a living. You're welcome to label simply being asked to put some substantiation against your claims as bullying, hectoring, making it up, quoting imaginative statistics etc... though really, data isn't hard to find. My current employer probably wouldn't have any interest in investing in coal even if the numbers added up though there are a ton of major energy industry players in Australia that would. You seem to assume that because it's ideological for you, it should be for anyone else holding a contrary opinion - not so. No conspiracies here. If the numbers work, it'll get investors. Simple. I personally/professionally haven't seen any numbers that work for coal, though you might have, so post 'em. I don't actually have a 'view' as you intimate. If the numbers add up, I'll support it. If they don't, won't. My honest opinions on coal might surprise you. If you label a bunch of people 'warmists', suggest Alan Finkel doesn't have a clue, that coal's a solution with zero substantiation in an open forum... whilst flattered you've made it personal, I'm hardly the only person here that'll call you out on that. If you've got some knowledge/opinions/views to share that show coal to be viable, I'll support you. FWIW this isn't how your post read. If you've got legitimate concerns around conduct, hit the report button and contact the forum mods. Certainly don't intend to bully anyone. Will concede the tone of your post had me a little riled and mine in response was a little sharp. If you're ever down here PM me and I'll happily offer beer. And you.
  7. electric cars

    We really don't know what the Roadster chassis is likely to be made of just yet. There's likely a good increase in density against base S. Wouldn't quite be i3 type construction (that'd be a bit soft for this) but yes, I'd mentioned this above. It's a lot of debt! They've bet the house big this time.
  8. Put down a price for one - or LCOE - and you (or anyone else) gets to talk about what would fix what. Right now there's a lot of 'HELE coal FTW' though not a lot of '$/kWh at $x capital cost'. Seriously - if the numbers add up then guess what, people will fund it. Haven't seen a proposal for a coal project that does just yet. Have you? In numbers? We have excess generation most of the time. If the storage is cheap enough, it's usable. At the right capital cost storage beats peaking plants and has good synchronous capacity in all markets... so it wins. Maths here is pretty simple.
  9. Kodi v Jriver

    They are, but... Winner Unless you're keen to put work into it on a Linux install, I wouldn't pretend Kodi is a better audiophile platform than JRiver (this from a daily Kodi user).
  10. electric cars

    Nope. It really isn't the battery (though I could think of a few ways of cooling the car rapidly on an ice bath exposed to the battery - which some hillclimb S's do). Don't know. They'll probably be 2170's so at least 25 Wh/cell for a start (roughly double what you'd get from 18650s). The nice thing about a really big capacity is that you could use it effectively for ballast, so you can run that mass wherever you like for packaging and/or mass distribution, and theoretically you could stack vertically - remember, cells don't heat uniformly and it's not as though you'll be drawing on all of the battery capacity all of the time, so a good BMS can manage this stuff accordingly (lots of temperature sensing). It could be done for around 1000kg, maybe (even) less depending on material, voltages, cooling architecture (something other than the 'snake' in the 18650 packs), some packaging optimisation, etc. For reference, S is around ~550kg per ~100kWh. We also don't really now what the rest of the car's intended to be made of. A Bugatti Chiron is around 2,000kg mass; I wouldn't imagine this to be far off... just with better packaging. $250k/car allows a lot of possibility. The knock-down cost for the pack isn't going to exceed $40k and probably a lot less by the time it goes into production (if made conventionally). It's a very (very!) competitive powertrain cost for a hypercar, and they'll probably reuse bits of the design in other things too. Might also consider that with almost infinite torque possibilities at very fast reaction times don't make the car lighter though they do atone for the impact of excess mass to some degree. I'd hope it's the EV that rips out a 'ring lap time enough to make the established supercar elite s**t themselves. I'd be sad if it was just 'point and squirt' fast. Some of the data is a little worrying; no one needs a 400km/h car and engineering safe for those speeds is... ridiculous work. It's a large reason why a Bugatti costs what it does and still isn't profitable. I thought Roadster redux was the more exciting part of the reveal, as it's genuine next-gen platform stuff for Tesla. I hope they sort their manufacturing dramas and last long enough to develop the Roadster properly and build it. Takes more cash to develop a new car for production than Tesla is losing in each quarter right now... hoping they get on top of it. I've got faith

    'Battery thermal management' is not 'the issue' limiting sustained performance for S/X. It is different. The cooling required goes beyond usual refrigerant/WEG (water ethylene glycol). Oil cooling is required for drivetrain components, unless Tesla has discovered something new there (unlikely). It's possible (but not guaranteed) that some key components are from a new, higher-voltage architecture. In a general sense bigger packs require less cooling overhead per kWh as there's less current per pack energy involved. Anecdotally it's not hard to make a car that will do a 9 sec quarter on a 200kWh pack. It's very hard to make one that'll do it on a 60kWh pack. It's harder to do so on a car that'll do a 'ring lap, though that's not max power out of pack at all times, and with 200kWh there's a lot of energy reserve that can be thrown into active cooling.
  12. Yes - don't do it. And skip the Redback... Goodwe inverter. Stay away. If you really want something like the Redback (modular, local, islandable, li-ion) look into SolarJuice Opal Storage. You can go to 13kWh (LG Chem) at decent power. Can also be had with Reposit integrated. Price is reasonable and your cash isn't in part going to Energy Australia but instead to people that were never in coal and always in solar. Runs SolaX kit which is among the best of the Chinese-made somewhere-else-designed kit. Next steps up get considerably more expensive - SolarEdge at 400V with limited battery choice (if single-phase), big German inverter/chargers (SMA etc) and whatever you like at 48VDC. Those options can get pretty hardy depending what ambient you need to throw at it (@125dBmonster can attest). You could go off the wall with a few Victrons at real low voltage and some Z-Cells... but I wouldn't. If the batteries going to be depended on under emergency conditions, think hard about the li-ion options. PM me if you want further details or a direct contact at SJ to talk about it. Would be happy to help.

    Got it in one.

    Nice pickup. Embodied carbon in the Tesla isn't small though, though comments over life cycle are about right. You could reasonably expect, over the life of your Tesla, grid power carbon intensity to drop 20-40% in VIC. It's not a huge amount relative to some of the regions cited though - most have nuclear baseload (counted at zero carbon), we don't - and the big Tesla does chew electrons at a decent clip... but it's not the only EV going, and there are big ICE cars too. Comparing carbon equivalency for FCVs as a means to green credentials is somewhat disingenuous. It's not completely the point of hydrogen storage.
