Cool to see you're on the forum man, think you've met my twin brother a few times (Brent). -

Yeah everyone always seems to refer to them as S13 wheels however they came on R32 Skyline, A31 Cefiro, C33 Laurel etc., and also came polished diamond cut or painted depending on the model. Congrats on your GTS purchase! I'd personally leave it NA.

In this thing about this 100% renewal energy stuff I hear no one really talking about anything other than power and fuel really Power and fuel, whilst being a huge part of how we use the billion year old Dinosaur juices, are only 2, of the probably thousands of things that we need to use it for in the chemicals industries for making nearly everything we use nowadays I'm all for a clean planet, but if we want to continue to have all the day to day appliances and stuff that we rely on everyday we will still need fossil fuels Whilst I do love science, and how it can bring innovation, there's really a limit to how far it can go in relation to "going green" As for EV's, unless your charging of your own solar panels, it isn't helping the environment when you consider the the batteries, the mining processes required, the manufacturing process required, and how long a batteries (read: the vehicle) lasts long term If I was supreme dictator of the world, I would ban the use of sugar for fizzy drinks and food additives and use that for ethanol manufacturing, petrol engines would be happier, and people would be alot healthier Disclaimer: Whiskey manufacturing would still be required, so says the supreme dictator of the world Same same for all the vegetable oils that get pumped into all our food, use that for bio diesel Disclaimer: the supreme dictator would still require olive oil to dip his bread in This would take some of heat off the use of the use of fossil fuels which are required for everything we use, unless you want to go back to pre 1800 for heat and power, or the early 1900's for plastics and every thing else that has come from cracking ethylene Would I be a fair and just dictator, nope, and I would probably be assassinated within my first few months, but would my cunning plan work, maybe, for a while, maybe not Meh, in the end in an over opinionated mildly educated arsehole typing out my vomit on my mobile phone, which wouldn't be possible without fossil fuels And if your into conspiracies, we only need the fossil fuels to last until a meteor hits, or thermonuclear annihilation, that would definitely fix our need for fossil fuels for manufacturing and power issues for quite some time Meh, time for this boomer to cook his lunch on his electric stove and then maybe go for a drive in my petrol car, for fun -

It really helps that light duty vehicles have absolutely appalling average efficiency due to poor average load. Like 25% average brake thermal efficiency when peak is somewhere around 38% these days. So even a 60% BTE stationary natural gas plant + transmission and charging losses still doing much better with an EV than conventional ICE. And that's before we get into renewables or "low carbon nonrenewable" nuclear which makes it a no-brainer, basically. In commercial aircraft or heavy duty diesel pulling some ridiculous amount of weight across a continent the numbers are much more difficult to make work. I honestly think in 5-10 years we will still be seeing something like the Achates opposed piston diesels in most semi trucks running on a blend of renewable/biodiesel. Applications where the energy density of diesel is just too critical to compromise. CARB is running trials of those engines right now to evaluate in real world drayage ops, probably because they're noticing that the numbers just don't work for electrification unless our plan is to make glorified electric trains with high voltage wires running along every major highway and only a token amount of battery to make it 30 miles or something like that after detaching. Transport emissions is not insignificant especially in the US, but yes there's a lot of industrial processes that also need to be decarbonized. I agree the scale of the problem is pretty insane but EDF managed to generate ~360 TWh from their nuclear reactors last year and this is with decades of underinvestment after the initial big push in the 70s and 80s. I don't think the frame of reference should be solar-limited. France is not exactly a big country either. Maybe it doesn't work everywhere, but it doesn't have to either. We just can't live off of fracking forever and expect things to be ok.
