Electric car?
Jump to: Newest in thread
It will be an electric car or nothing in a couple of decades. And EVs will likely be cheaper (overall) than regular cars way sooner than that.
Have you considered getting one sooner rather than later?
Or have you already got one and if so are you impressed? |

"Not as environmentally friendly as they claim to be and they’re fucking dangerous to pedestrians as they suddenly move with no warning. "
They're more environmentally friendly than regular cars.
Can't wait til they become the norm. |

Mr N nearly got run over by one yesterday. The driver wound his window down and apologised for it being silent. They need to make them noisy, partially sited people like my father will be in danger.
Their environmental credentials are surely dependent on how the electricity that powers them is generated. |

They are required (by EU law) to make an artificial noise up to 40mph to alert pedestrians. But you can turn the noise off. Certainly shouldn’t where folk are around.
They are absolutely more green than normal cars.
And if green credentials concern you, there are plenty of renewable-only energy suppliers.
A lots have really good safety features, too like autonomous emergency braking. |

This one yesterday wasn't making enough noise to ber heard on a busy street.
Yes, I onow about renewable only suppliers. |

What happened to cars being powered by hydrogen? It was on Top Gear years ago all that comes out of the exhaust was water vapour. But for some reason it was dropped. |

We’ve test driven a few and they are so good to drive. Nothing else I have driven has as smooth a drive as an EV. Our fave was the BMW i3, sadly out of our price range. I think they’re a viable option for city living, but not for us right now due to the distances we do. We’re holding on for better batteries. An EV is definitely on our wish list for the future.
We also have solar panels, which would make driving one definitely the eco-friendly option in our case. |

"What happened to cars being powered by hydrogen? It was on Top Gear years ago all that comes out of the exhaust was water vapour. But for some reason it was dropped."
Because hydrogen can't (currently) be effectively stored for any real length of time. The molecules are to small so they essentially leak through whatever material the tank is made of.
Plus, although it's the most abundant element in the universe, annoyingly it's almost always stuck to other elements, oxygen in the case of water. To unstick it uses more energy than the hydrogen releases, so it's not efficient to do so. |

The hyundai Kona does 300 miles and charges from 20 to 80% in about 40 minutes.
My hyundai ioniq does 120 miles and charges in 20 minutes.
Since the majority of cars do less than 100 miles a day, it makes sense to get one most suited to the job.
Having said that, relying on the public rapid CCS chargers is a nightmare as they are too often out of service.
The Zappi charger can use only excess energy from your solar panels to charge the car. |

All mass generated electricity is massivly more efficient than an internal combustion engine that doesnt even get 30%
Its more battery production and the scrapping of an existing serviceable car to replace with an ev that makes up the difference.
But electric motors are far more suited to vehicles than combustion engines as they produce peak torque at 0rpm, the point you actually need torque |

Quick swap batteries at fuel stations is the expected route prototypes are already being tested.
Basically you park at the "pump" and a robot arm removes your battery and puts it in a charging dock and fits a fully charged one to yours.
Batteries would be a service contract rather than part of the car |

What gets me with electric cars is this charging up its a scam . Fariday prooved in 18 hundreds anything with a shaf turning in a housing can generate electricity using magnates . So everything on wheels that moovs can re charge itself constantly |

It would be no use to me currently - the nearest I can park to my house is about a hundred yards - across two other streets, so no chance of charging from home |

Errr thst takes energy
So if your battery turns a motor that is connected to an equally rated generator it wouldn't move and at best just slowly lose power to heat through friction or resistance.
But stalling a motor like that would just burn it out |

That’s pretty much the situation I find myself in. There are schemes running where the council provide charge points on street lamps.
And there are chargers being installed at a lot of venues like health clubs (Bannatynes) and retail outlets (Ikea, Sainsbury, Tesco etc), and almost all motorway services.
There is a charger at Sheffield Technology Centre which is free to use, which I’ve found handy.
Still, coverage isn’t going to be convenient for everyone. It will be, though. |

I used a Nissan leaf as a work car on Gatwick they were awful, they couldn't last a 12 hour shift that is without the heaters being on.
The car had a 100 mile range as well, they are not bad for city driving not long journeys. |

I am waiting for the injury compensation phone calls "tripped over an extension cable crossing the pavement?" 
I don't know if electric cars are the answer, the UK has 70 people per square mile which means we live in high density pretty much everywhere, houses with private drives / garages are going to be a minority of people.
I think we need a different plan, just not sure what that can be. |

Not yet, But it is now possible to have an LED light that uses so little current that it can shine on a solar panel and keep itself powered. With a little extra current produced for other uses...
Therefore in theory if you have lots of them inside small cubes of solar panels it may make enough surplus to charge a battery.
Which could approximate perpetual motion or at least free energy, one day. |

Ridesharing, charging at workplaces instead of at home, plugging in to lampposts / parking meters. Induction charging is also clearly a capability, it "just" needs to be scaled up.
I agree there are details to sort out, and many of them, but there are plenty of ways for a dense population to charge EVs. |

Where's the extra energy coming from? Especially as solar panels aren't 100% efficient when they're made, and degrade over time. |

Battery’s and the magnets for the motor are made from rare earth.
Rare earth material is mostly produced in China. Big downside mining and settling lagoons are major polluters poisoning water tables.
Cleaning up here but crapping elsware.
There is always a price to be paid.

No its not. An Led powering a solar pannel with 20% efficiency will turn off instantly as its gping to be losing greater than 80% of its out put not even considering resistive loses
Perpetual motion or free energy doesnt exist |

"We can’t produce enough electricity to do this plus the battery’s these vehicles use aren’t environmentally friendly hydrogen should be the future "
Of course we can produce enough electricity to do this. Mass generation of electricity is fairy easy.
How is hydrogen the answer when its less efficient and would require far more electricity to produce and transport than just sending electricity through wires |

Plus when we all have to drive them you will be paying road tax then not car tax so you won't gain anything. The range of these electric cars is pathetic. These batteries are94%non recycleble
Wait till there's a mountain of these piling up in the future. People moan about the plastic issue. There's a whole new challenge lurking in the distance. If man is as clever as he claims to be why does he keep making things you can't get rid of. Well done |

Because of economy of scale and improvements in technology, wind farms are now producing electricity at half the cost of the subsidised new hinkley nuclear power station.
Solar, wind and wave could easily produce all the power we need. Was it 2017 or 2018 that we didn’t burn any coal for the first time for extended periods because it was sunny and there are enough solar installations to generate a significant chunk of needed juice?
Electric is the way. |

the right frame of mind -London |
I think the future has less to do with the propulsion system than the ownership model. i would foresee that autonomous/ driverless cars will more and more become the norm and that the natural consequence of this will be that there will be less and less of a demand for ownership / that people will start switching to a pay by use model. After all, most cars spend the vast majority of their life parked. If you no longer are physically in control of the vehicle, you start to see it less as an extension of yourself and rather see it as a service much like your utilities. Car clubs are an interesting step in this direction too. |

It is being done, differentials are tiny at the moment, and obviously a start up light source is needed, but once lit the LED doesnt go out, and there is a measurable excess. It may one day be usable.
It is about time we changed from rotation being the only source of energy. Maybe a surplus generating cube makes it time to think inside the box

No its not been done. For it to work it would require an LED with more than 100% efficiency at turning electricity to light with no loses, no heat produced.
Then it would require a solar panel with 100% efficency with no losses turning every photon to electricity
.then it would require wires with no resistance losing nothing to heat.
Closest of those 3 things we can do is super conductors for the wires but they require a massive ampunt of energy input for thier cryogenic cooling.
Energy csnnot be created or destroyed merely transformed for your device to produce excess energy it would have to be converting matter into energy directly which would be extraordinary and kill it as a tech as it would be a portable nuclear weapon |

Why not?
An adequately sized electric motor could produce way more torque than youd ever get out of a combustion engine in one the low range for off roading would be immense

Just something i feel. Besides the energy consumption of an electric vehicle depends on it's weight, values are always given for an empty vehicle over level terrain. I know i can get over 400 miles out of a tank regardless of what i'm carrying, how i'm driving or the terrain i'm crossing. |

There are vast trucks which move boulders from the top of a quarry to the bottom. They regenerate so much energy driving down that they have enough to feed power in to the grid before driving back up.
It’s possible to produce an electric version of your truck. |

Perhaps. Interestingly i've been advised to keep my old truck on the road for as long as possible by my garage rather than buy a newer more efficient one.
Also, if you believe as i do, that the environmental cost of building a new car and scrapping an old one far outstrips the saving made by a new vehicle it doesn't make sense.
Also there's the environmental cost of mining the materials needed to make batteries, of which i'm led to believe are an insufficient resource, the manufacture of new and disposal of old batteries which are themselves extremely toxic. |

Yeah for ling distance off roading its going to take some time.
Theres an interesting area in hybrids in this regard though.
Engines work best if they are designed to run at one specific speed and load not the varying loads we put them under
Generators the same they csn be designed to work very efficiently with a fixed input.
Electric motors work far better over a range than a combustion engine.
So we will likley be seeing a combustion engine paired to a generator that provides the power to run the kotors that provides thw drive (not nessercirly piston, theres some wave type ones that would be useless for a range like a car but ideal for a generator)
Torque characteristics of electric motors with the fuel ease of combustion engine.
Its already common on ships etc the main drawback for using them in cars is the most efficient engine for a generator is a jet turbine but very hot exhaust and very loud operation mean they arent comming to the street any time soon. Not an issue on a ship where you can have massive heat exchangers and turbines to recover that wasted heat and noise |

Well no you'd nees far less than 2 sets per car, as not every car would be swapping battery at exactly the same time. And it doesnt have to be the main one it can be a supplemental one.
But youd save mountains of co2 and waste simply by removing the need to refine petrol.
Personally as a biker i cant wait for electric to take over so i dont have to play "dodge the oil and diesel" every day rather than the environmental concerns.
But lithium batteries can be recycled they arent currently as its not in demand just like lead acid ones didnt used to be recycled but not they are at something like 98% in developed countries (and we produce hundreds of thousands of tonnes of them a year as waste) |

There are plenty of petrol cars that are almost totally silent when pulling away gently and wouldn't be heard over the general noise of a street.
Once it is the norm to have an electric car, people will become used to them..
For pedestrians there is the green cross code, stop, look and listen.. for those with hearing problems, its a case of stop, look and look again.. for the blind, unfortunately I fear a more Darwinian approach may be the case..
New cars do come with a plethora of safety features and it may be the case that 360' automatic pedestrian monitoring is fitted to all cars by law, the technology already exists and is relatively cheap in comparison to some safety features we take for granted. |

I'm afraid i'm not buying the argument. From a personal perspective it all seems so hugely impractical.
I agree that something needs to be done but for anything beyond a city commute i can't see it working. There are too many issues that haven't been addressed. |

More impractical than diging ancient compressed algee out from under the ground or sea, negotiating with some of the worlds most oppressive regimes to do so.
Loading it up on to tankers and into pipelines to ship it tens of thousands of kilometers to then expend vast amounts of energy boiling distilling and fractioning it before adding detergents and other aditives.
Loading it on to lorries and shipping it 24/7 across whole countries to tiny distribution centers?
The practicalities and logistics of battaries are a cake walk in comparison to fuels the issue is simply energy density.
As tjat increases to parity fuel becomes an expensive luxuary for us petrol heads.
The hot swap stations tested so far are just automated park pay and drive off.
The other option is hondas one theyre about the size of a cooler box with a handle.
Park open bonnet lift it out and swap it close bonnet and drive off. |

I hear what you're saying but that system is already in place. What's being suggested will require a massive shift in both mindset and infrastructure. I was actually looking closer to home.
The biggest problem i have with going electric is where we're supposed to be getting it from. Our electricity grid is already stretched, how is it supposed to cope with the extra burden? We will have to rely on nuclear more and more, switching one problem for another. We think we can just bury this toxic waste in the ground and forget about it like burying our heads in the sand knowing full well the risk that lasts thousands of years. Not to mention the current farces of Hinckley and Anglesey. |

"Also there's the environmental cost of mining the materials needed to make batteries, of which i'm led to believe are an insufficient resource, the manufacture of new and disposal of old batteries which are themselves extremely toxic."
Old batteries are very often recycled. Nissan Leaf batteries, for example are used in some schemes I've seen for storage systems.
Also I'm not suggesting that we should scap perfectly working ICE cars ahead of their natural end of life.
"Personally as a biker i cant wait for electric to take over so i dont have to play "dodge the oil and diesel" every day rather than the environmental concerns."
This. Has had me off a bike.
Re getting used to silent cars, as anyone gone for a walk in Amsterdam for the first time without annoying cyclists?
Been said a few times that they are dangerous because they are quiet. The EU states that EVs have to have a sound system for pedestrian safety.
"The biggest problem i have with going electric is where we're supposed to be getting it from. Our electricity grid is already stretched, how is it supposed to cope with the extra burden? "
There are ways to mitigate spikes in power like storing energy when it's abundant and storing in big batteries for later use.
Didn't Elon Musk install a system like this in Australia?

"It is being done, differentials are tiny at the moment, and obviously a start up light source is needed, but once lit the LED doesnt go out, and there is a measurable excess. It may one day be usable.

Under the laws of physics, where is this extra energy coming from? You have, according to the description you've given, a closed loop that is producing spontaneous energy (ignoring inefficiencies in production). |

"Mr N nearly got run over by one yesterday. The driver wound his window down and apologised for it being silent. They need to make them noisy, partially sited people like my father will be in danger.
Their environmental credentials are surely dependent on how the electricity that powers them is generated."
Not to mention how the lithium for the batteries is obtained... my worry is about these being filled with conflict minerals and also becoming an environmental hazard to dispose of! |

I did say may be one day... I saw it demonstrated when searching potential uses of graphine. I can't remember the numbers but the surplus was microscopic, but give it time and enough of them and it has potential. It will possibly be invented before brexit is agreed |

OK, I'll rephrase.
Where, one day, will the microscopic surplus come from, according to these scientists?
Note, I'm not holding you responsible for this at all, I'm just curious as to the precise bullshit that must underpin that claim. |
