Now that fuel sourcing from waste plastic has been finalised and proven, there is an enourmous sourceof fuel available. ICE vehicles are (at present) longer lasting with a much smaller carbon hole, than EV's (and EV's carbon hole is huge). But that doesn't demonstrate that ICE is sustainable. Its proven again and again that extracting stuff from the ground and burning it is not sustainable. Even IF fuel were to be sourced from plastic, it is still ultimately coming from oil which is a finite resource. Yes EVs have their own issues to be addressed, but this is a completely separate question to the sustainability of ICE. Quote Link to comment Share on other sites More sharing options...
Snagger Posted September 9, 2022 Share Posted September 9, 2022 Using waste plastics to create fuel will be an enormous feather in the cap of ICE sustainability, along with biofuels and synthetic fuels. They don’t need to compete with EVs - the two systems can complement each other, EVs being so well suited to cities and towns where they are most efficient and where air quality and noise are important considerations, and helping to reduce the need for fuels, while ICE running on the later fuels will reduce grid demand, provide the long range and heavy transport needs and also allow for flexibility when there are grid problems, like EVs can provide options when there are fuel distribution issues. They should be seen as a symbiotic solution, not a cut throat binary decision. I saw this last night and though it interesting. It is in the western US, but seems to match what I hear from the UK and presents a similar debate. It’s by an ardent EV supporter (who used to present some videos for Fully Charged), so is not anti EV at all, but it highlights a big issue.

reb78 Posted September 9, 2022 Share Posted September 9, 2022 (edited) At least using waste plastic for fuel production should mean that less of the damn stuff ends up polluting the oceans. I despair at the impossible task of not using plastic. Its everywhere! So much of it just gets sent of for incineration anyway (labelled as recycling ) that we may as well convert it to fuel and burn it that way.

FridgeFreezer Posted September 9, 2022 Share Posted September 9, 2022 Burning plastic to generate power to run EV's would be more efficient, ICE engines are very poor at converting energy to motion - I think it's been said it's more efficient / friendly to run an EV on energy produced from fossil fuels than it is to pour it directly into the tank and run an ICE vehicle on it, even accounting for losses in transmission etc. Also not sure where the idea that EV's aren't as long-lived as ICE vehicles comes from, surely it's a bit early to really tell? 1 Quote Link to comment Share on other sites More sharing options...
monkie Posted September 9, 2022 Share Posted September 9, 2022 I agree totally with stopping as much plastic as possible getting into the oceans and also the ability to repurpose things rather than dumping them where ever possible is great and I think we should be doing this... But, do we not all agree that burning things is ultimately not sustainable in the long term? I don't think it is, which is why I wanted to highlight that statement. Surely as a species, we ultimately need to go down a path that leads to the ability to source our energy from not burning resources and releasing the waste poducts into the atmosphere? 1 Quote Link to comment Share on other sites More sharing options...

One of the benefits of "static" ICE generation is that you can tune the engine for optimal efficiency and you can better capture "waste" energy. For example (my memory is a little hazy so bear with me) my old department at Imperial achieved >90% efficient ICE electricity generation because they used I think it was gas inside (what used to be a) diesel engine. But all the excess heat was captured and used for central heating within the campus and the Royal Albert Hall which accounts for most of the inefficiency of vehicle based systems.

From what I understand, it’s quite the opposite. Apart from the fact that most EVs are pretty new and so their body shells have more modern anti corrosion remedies, electric motors have very few moving parts to wear, many not even using brushes or contacts, no coolant in the motors to cause corrosion and simpler, more robust transmissions. There really is a lot to admire about them. 2 Quote Link to comment Share on other sites More sharing options...

I lived in the south of England for a few months many years ago and was appalled at the situation country workers found themselves in. You should be reassured that, just by caring and thinking about the future consequences of how we live, you are doing better than most and something will definitely stick with your kids. Just watch it happen! I've decided my dire current circumstances also have given me an opportunity. I am standing for regional council in our local elections. Regional councils here are tasked with certain aspects of environmental management and public transport. I really hope I can get voted on, so that I can help steer public thinking to less trendy and more logical solutions, not to mention towards a more cooperative and less blame-slinging culture. We will see! Inevitably, the topic of electric vehicles will come up for debate... Can you imagine local authorities considering electric conversions rather than full-on vehicle replacement for short run transport? These ideas must be rattling around thousands of authorities across our planet these days. Quote Link to comment Share on other sites More sharing options...

simonr Posted September 23, 2022 Share Posted September 23, 2022 1 hour ago, FridgeFreezer said: Can I ask what sort of costs are involved in something like this these days? I spent about £7.5k. Batteries were £2k of that, for 13.5kWh. For a regular vehicle (heavier than this, Actually Don Incol's Lightweight LR) a rule of thumb seems to be Pack kWh x 2.5 = Range in miles. Based on being half the weight, but about the same drag coefficient, I'm betting on 50m+ range at 30mph & 30m range at 50mph. So, for a 100m range in a Land Rover using new batteries, I would expect to pay about £15k for the bits. If you use 'pre-loved' batteries and maybe a Nissan Leaf motor (which has been thoroughly hacked now, using a 'Thunderstruck' controller), a bit less maybe. The main thing I would change is I were starting over would be to use pre-made battery modules. The amount of extra thinking & construction that needs to go into making your own with heating, cooling & management - isn't worth it! 1 1 Quote Link to comment Share on other sites More sharing options...
