You reckon?

I have to disagree. Notwithstanding that at some point we may all be forced to do this to our cars if we want to keep driving them, there is absolutely nothing about an electric-converted-previously-IC-car that is ever good. EVs that are built by OEMs on platforms that were originally IC already suck, let alone the shitty outcomes that result from doing it as a retro to something that was actually built as an IC car. This is because the platform really needs to be designed to house the battery in a useful place (ie, down as low as possible) and the motors are properly located relative to the wheels that they have to drive. Converted platforms already suck at this. But when you try to shove sufficient battery capacity into a previously IC car, you can't put it down on/in the floor, because that space doesn't exist. You can't find enough space where the fuel tank used to be (if it is an inboard fuel tank) and you don't want to hang it out behind the rear axle line if you had a rear fuel tank. And there's not enough space in the tunnel if you still want to use it for anything remotely like what it was originally used for. The engine bay is too big for a motor, and you'd really prefer that the motor for the rear wheels wasn't in the front engine bay anyway. And there's not enough room where the diff was for a proper man-sized E motor.

And then.... there is the complete lack of soul and emotion that is provided by EVs.

There are some cracking restomods out there. Like the Alfaholics GTA thingo. But it is petrol powered. Look at the alternative EV version of a GTA restomod by Totem. it is jaw droppingly beautiful. But by all reports is is objectively awful to drive, despite having 600 HP or something, simply because there is nothing there. It sounds like a sewing machine or a leaf blower. It should scream and wail and make the hairs on your neck stand up.

Oh, and it's 1500 bloody kg in a car that was <900kg when new. GTRs are heavy enough as it is without pushing them up to 2tonnes worth of pork.

Hahaha yep, point(s) taken.

I just like seeing different things and an EV in an R32 is pretty different.

I'm not on the EV band wagon, I'm waiting for synthetic fuels or hydrogen personally. 

H2 (for cars) will never happen. It's not reasonable for any number of reasons. It's also not reasonable for almost all of the industrial uses that the fanbois say that it will be used for, again for a large number of reasons. There are some cases where it will be good. But, even those will be massively hampered by the economics. The only way that H2 can be economic is if we somehow manage to get from where we are to the other side of the economic-valley-of-death in which no-one can operate. You need there to be sufficient renewable generated electricity to be available so that it is effectively free. Once you are there, you can do whatever the hell you want and hang the efficiency. But until you get there, the ever diminishing value of electricity makes it harder and harder to encourage businesses to build the new generation capacity, and they will simply stop investing in generation projects. (I kinda think there needs to be just government money spent on building the required capacity in a non-commercial way, similar to how the first fossil fueled grids were built, as national-government owned utilities. And probably some nuclear in there to start. But this all should have started 10-15 years ago to avoid the chasm of death that we face right now).

Synth fuels will be much more likely, but will only occur is there is at least some renewable H2 production, because you need H2 to do it. And you need stacks of free (or at least extraordinarily cheap) energy because assembling molecules back into fuels is exactly the opposite process to burning the fuel, and the reason we burn fuels is because there is so much energy squeezed into each molecule. So you're somewhat subject to the same economic valley of death problem as above anyway. That is unless people are willing to pay the current equivalent of $5 or $6 per litre of petrol-ish liquid fuels. Can you imagine it? The squealing at $2 now is bad enough.

And at over $2 per litre I'm starting to consider setting up a corn mash still and converting over to alcohol and running mine on it ! 

Up side of that is it all doesn't have to go into the car !

I can't agree. If we hadn't all been brought up with the noise caused by the inefficiency of an ICE, no-one would actually ask for all that.

An EV is like any other car, it just goes better.

What about renewable diesel and/or gasoline? I see some projects spinning up like de-oxygenating ethanol to make drop-in compatible bio-gasoline especially in CA. I still think the future is EVs and we should've all gone full throttle on nuclear power after the 1973 oil crisis like France. Despite 15 years of work in CA to reduce the CO2 intensity of generation with renewables our electric grid is still far worse than even "low carbon" nuclear power.

ICE is pretty cool when you aren't depending on the stupid thing to be practical and reliable and cheap as possible to get you to work every day. It's kind of like mechanical watches or vacuum tube amps.

Well.... it's not just "de-oxygenating". If you do that you just have, most likely, ethane. So you still need to do a synthesis step to combine a number of ethanes/ethanols to make circa-8-chain hydrocarbons. And of course you don't want straight chain HCs, because n-octane actually has a negative octane rating (ie, it's worse even than the n-heptane which sets the zero on the octane scale!), so you have to do some tricky catalytic chemistry to synthesise branched HCs.

That's all doable - but it doesn't come for free. And.... it starts with ethanol, which is an agricultural product, and there will almost certainly never be enough of that as a base stock to replace the liquid fuels that are in use. You really wouldn't want to be planning to be using any more ethanol for fuels than is currently already used (in E10, E85s, etc). And ideally you'd be looking to reduce such usage, as it is largely wasteful, particularly in the stupid-ole'US-of-A where the corn lobby has organised it so that it's actually primary production corn that is used to make a lot of the ethanol, not by-products and waste, like it is (mostly) elsewhere.

So, what I said about needing free-ish energy probably still applies.

True synth fuels would be made from H2 and CO2, in a near reversal of the combustion process. In fact, given that the H2 would be split from water first, it actually is a complete reversal of the combustion process. But...energy intensive.

The human race burns something like 1 cubic MILE of crude oil, after it has been made into various fuels. Every year. That's a simply stupendous amount of energy. Just assume that the density is 900 kg/m3, and that the calorific value is 45 MJ/kg, then that is 165.9 x10^12 MJ of energy. Or more than 10^19 Joules.

You get a maximum of 1 kJ/s per square meter solar radiation falling on the planet's surface, and so if you halve that for daylight, and halve it again for average weather (highly optimistic) and then take ~25% for the very best efficiency of solar panels, then you need about 85.7 billion square metres of solar panels to generate enough electricity to replace that liquid fuel energy consumption. Each panel is about 1m2. That's a rather large number of panels.

We also burn about a cubic mile of coal.

We also use hydroelectric power. We also use nuclear. We also use a number of other sources, both "renewable" and not. You can kind of ignore the renewable ones (except for hydro, because it will all end up getting subsumed into pumped hydro for storing other renewables, and so it won't be the standalone renewable that it originally was), so we end up needing a multiple of the ground area number that I just arrived at.

Somehow Vertimass/Oak Ridge National Labs has figured out a catalyst that can convert ethanol into C9-C10 hydrocarbons in basically a single step without ending up with a bunch of ethylene or similar waste products: https://patents.google.com/patent/WO2023224867A1/en

I still don't think anything like this will keep us from needing to transition to EVs regardless along with all kinds of other electrification, but things like this will go a long way towards alleviating the problem of how to electrify things like planes. Renewable diesel is seemingly an easier problem as well, Chevron is already running refineries for the stuff and the primary feedstock is tallow and other waste fats from agriculture.

Yes...but look at the numbers. There is a tiny tiny fraction of the number of Joules available, compared to what is used/needed.

Just because things are "possible" doesn't make them meaningful.

As somebody who works in the energy sector and lives in a subzero climate, i'm convinced EV's will never be the bulk of our transport. 

EV battery and vehicle companies over here have been going bankrupt on a weekly basis the last year.

@GTSBoy out of the cubic mile of crude oil we burn each year, I wonder how much of that is actually used for providing petrol and diesel.

 

From memory the figure for cars in Australia, is that they only add up to about 2 to 3% of our CO2 production. Which means something else here is burning a shit tonne of stuff to make CO2, and we're not really straight up burning oil everywhere, so our CO2 production is coming from elsewhere too.

 

Also we should totally just run thermal energy from deep in the ground. That way we can start to cool the inside of the planet and reverse global warming (PS, this last paragraph is a total piss take)

Yeah, all the crude is used for fuels and petrochem feedstocks (pesticides, many other chemicals, etc etc). But increasingly over the last few decades, much of the petrochem synthessis has started with methane because NG has been cheaper than oil, cleaner and easier and more consistent to work with, etc etc etc. So it's really had to say what the fraction either way is.

Suffice to say - the direct fuels fraction is not insigificant. Heavy transport uses excruciatingly large amounts. Diesel is wasted in jet heaters in North American garages and workshops, thrown down drill holes in quarries, pissed all over the wall to provide electricity to certain outback communities, etc etc. Obviously road transport, and our pet project, recreational consumption camouflaged as road transport, is a smaller fraction of the total liquid HC consumption again.

If you're talking aboust Aussie cars' contribution to the absolute total CO2 production of the country, then of course our share of the cubic mile of coal that is used for power generation, metallurgy, etc adds up to a big chunk. Then there is the consumption of timber. Did you know that the production of silicon metal, for example, is done in Australia by using hardwood? And f**king lots and lots and lots of hardwood at that. Until recently, it was f**king jarrah! There are many such sneaky contributors to CO2 production in industry and farming.

NG is used in massive quantities in Australia, for power gen, for running huge water pumps (like, 1-2MW sized caterpillar V16 engines running flat out pumping water) for places like mine sites and minerals/metals refineries. And there are just a huge number of those sort of things going on quietly in the background. So NG use is a big fraction of total CO2 production here. I mean, shit, I personally design burners that are used in furnaces here in Oz that use multiple MW of gas all day every day. The largest such that I've done (not here in Oz) was rated to 150MW. One. Single. Gas burner. In a cement clinker kiln. There are thousands of such things out there in the world. There are double digits of them just here in Oz. (OK< just barely double digits now that a lot of them have shut - and they are all <100MW).

But it's all the same to me. People in the car world (like this forum's users) would like to think that you only have to create an industrial capability to replace the fuel that they will be using in 10 years time, and imagine that everyone else will be driving EVs. And while the latter part of that is largely true, the liquid HC fuel industry as a whole is so much more massive than the bit used for cars, that there will be no commercial pressure to produce "renewable" "synthetic" fuels just for cars, when 100x that much would still be being burnt straight from the well. You have to replace it all, or you're not doing what is required.

And then you get back to my massive numbers. People don't handle massive numbers at all well. Once you get past about 7 or 8 zeros, it becomes meaningless for most people.

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.

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

I am not sure how many of his original team krazy friends are still on here or active but thought it reasonable to let the forum know.    if you have any photos or pictures it would be great if you could share them.    it took me a while to work out he was active on here.    thanks so much

    • 😜 hopefully we get this instead of a new R36 GTR due to recent financial problems at Nissan. Nismo to sell a complete kit with RB26 and driveline. All starts making sense (ok maybe not) once the Nissan Leaf's (Leaves?) with stuffed EV motors/batteries hit the market cheap
    • Hi guys , have had allot of time for SAU and has helped me out heaps in the past so I thought I would give it a go , I have my QM1 white NUR for sale 1 of 156 examples built by Nissan. Serious personal messages please if interested and details will be provided , asking 500k 
    • Oof. Could be worse I guess. I suppose they haven't put any effort into ally suspension parts or CF panels, seats, etc. So they could probably pull about half of that back out of the car. Not like a bunch of other EVs that already have CF everything and roll the scales at ~2t.
