A hydrogen vehicle is a vehicle that uses hydrogen fuel for motive power. Hydrogen vehicles include hydrogen-fueled space rockets, as well as automobiles and other transportation vehicles. The power plants of such vehicles convert the chemical energy of hydrogen to mechanical energy either by burning hydrogen in an internal combustion engine, or, more commonly, by reacting hydrogen with oxygen in a fuel cell to run electric motors. Widespread use of hydrogen for fueling transportation is a key element of a proposed hydrogen economy.[2]

As of 2016, there are three models of hydrogen cars publicly available in select markets: the Toyota Mirai, the Hyundai Nexo, and the Honda Clarity. Several other companies are working to develop hydrogen cars. As of 2014, 95% of hydrogen is made from natural gas. It can be produced by thermochemical or pyrolytic means using renewable feedstocks, but that is an expensive process.[3] Renewable electricity can however be used to power the conversion of water into hydrogen: Integrated wind-to-hydrogen (power-to-gas) plants, using electrolysis of water, are exploring technologies to deliver costs low enough, and quantities great enough, to compete with hydrogen production using natural gas.[4] The drawbacks of hydrogen use are high carbon emissions intensity when produced from natural gas, capital cost burden, low energy content per unit volume at ambient conditions, production and compression of hydrogen, and the investment required in filling stations to dispense hydrogen

I have since read in the New Scientist (June 9th) that reported that the electric car noise law will become mandatory on all new cars sold in the EU in 2020 (or was it 2021?).

Because of the multifarious regulations re cars in many different countries, most cars have all the various requirements where they don't conflict. So regardless of the Brexshit mess, they will probably have the noises in the UK. I do seriously expect there to be custom retro-fit kits and personalised noises. And bloody volume!

Regarding driving through car parks. Well, I show up daily at a coffee establishment in front of a mini-mall. There is 90 degree parking on both sides of the access 'street' which bears no name yet is treated as a street because it is open at each end. 90% of the folks there ae slow and careful, but those who treat it like a street are not on a schedule and there are near misses all the time.

Come to think of it, there are parking areas where people drive through at street speeds as well.

So yes, pedestrians have priority. But at their peril!

And I just remembered that horror story about the kid in a pickup truck who drove into about ten motorcycles, and killed seven. Being right doesn't lead to staying alive.

I refer you to John B Goodenough - Watch this space.

And petrol cars driven in car parks are a menace. Car parks are for stationary cars, pedestrians have priority, but not in the minds of some. Some self centred idiots. Artificial noises are not beyond the bounds of technology, marketing or the legislature.

Don't forget that it was an electric car that held the world speed record when petrol engines were still pre-adolescent.
Petrol engine design is mature now, the exponential improvements thereto are close to the asymptote. Electric cars have been given a new avenue of improvement with a new asymptote.

It all depends what timescale you are envisioning. Give it 10 years, I fully intend being around to see if I am right.

I can see potential for an entrepreneur to have electric hire cars at intervals fully charged. Leave the empty one to charge for the next person. Not a cheap solution but how cheap is boiling water to extract fuel from tar sands, then ferrying petrol around the country? Look to the total cost, and then look to the environment and pollution in the hinterlands of Canada.

FWIW I see the mix of driven and driverless cars far more of concern. And there is momentum building in that genre!

Mr Red, the majority of collisions happen at low speed. Parking lots, for example, are veritable hot-beds of collision risk, with vehicles and pedestrians starting abruptly without warning and wandering around at unpredictable angles, all at low speed. What low-speed collisions are not is, typically, likely to cause a fatal injury -- unless, of course, the slowly moving vehicle knocks a pedestrian down and then proceeds to roll over her. Which happens.

Until the car industry can produce an electric vehicle that can cover typical inter-urban distances in Canada, in winter, in the same time and at about the same cost as a petrol- or diesel-fired vehicle, sales in this country will be paltry.

It will be easy to not hear them .... at low speeds, when danger is at its least. At 30 mph the tyre noise is way up cf normal cars (not pimped megaphonies). And they will market special loudspeakers to make a noise, and then it will be the fashion to make non-car type noises. Goddamit they make trucks that shout "stand clear" just when they are stopped at traffic lights, let alone reversing!

In the northern climes ..... AFAIK, all batteries loose capacity at lower temperatures, through capacity & internal resistance. Then there is the need for a heater. I well remember going for a job at Lucas Industries in the 70s. They had two prototype electric vehicles and they were fast. Then I noticed the filler cap and wondered why they had left it on there. "Paraffin for heating" says the man!

There are battery life issues, but there are end of life solutions like home storage, which is not as wearing on the battery. And in 10 years the efforts of the father of the Lithium Ion battery John_B._Goodenough (and team) will have perfected his new idea. He is still working on it in his 90s. And the race is on elsewhere because of all the battery gadgets around.

If it's Betamax v VHS all over again, the momentum is obvious, apart from sheer cost comparisons.

Well, what's most likely to happen is what's happened in the past. Those who wish to spend the money form the leading edge of new-tech consumers. I've been on the highways of California and noticed the sleek Teslas gliding through traffic, and I've noticed people noticing them. I've seen exactly one Tesla in Anchorage, and full of old fashioned ideas of how things get done, I followed the car until I had an opportunity of asking the driver who owned the Tesla dealership? Silly OLD me. You buy them off the internet!
And what will really sell them in America is that electric motors have ultimate low end torque and, if made properly will be extremely low wear and maintenance, kinda the motor equivalent of the LED lightbulb (although my bedside LED lamp just died). Whether powered directly by batteries or fuel cells, or hybrid, electric motors will have their own appeal.

In the northern climes, or for anywhere that still gets cold after the planet has warmed up, there will be a slight electric disadvantage in that it is expensive to use electricty as a heat source. Reason being, unless you're using hydroelectric or nuclear sources for your electrical generation, chances are high in America anyway that you've burned something somewhere for that electricity. So using electricty as a heater source, although typically safe and clean, means that you've burned fuel to be turned to electricity to be turned into heat, when you could've simply burned the fuel for heat to begin with. Nevertheless, for a large part of the modern world, the freedom from exhaust pollution in crowded cities and suburbs and the ability to charge one's vehicle overnight when the electric rates might be lower will be liberating.

Also, in theory AND practice, movement through electric motors will be more efficient than through internal combustion and transmission systems. There are even some electric aircraft on the market.

Now, everyone should know that you don't use technology without tradeoffs. One of them will be that the damn things are way quieter than traditional auto engines. It will be easy to not hear them when you're crossing the street reading your phone....So there will have to be car announcers that are always on if the engine is on and the vehicle is moving. You can have the traditional back-up beep that so many trucks and delivery vehicles have, plus a somewhat smoother or purrier sound for forward motion. Maybe even a warning rattle for 'not moving, but not off'. And the approaching car might be able to bluetooth you on your phone you're reading and warn you explicitly to get out of the way. Or it could slow down while your phone prepares to file a suit in preparation for your anticipated injuries.

And like I writted earlier, for certain maintenance or repair the electromechanic will have to go through a grounding procedure before sticking his low-resistance digits where they might be fried off (in the electrical business the technical term for this effect is 'crispy critters'). And batteries under impact may short out and lead to electrocuted people and flash fires. Likewise with fuel cells.

It's a Brave New World all over again.

Gyroscopic forces are quite distinct from torque reaction. On motorcycles you would not normally notice gyroscopic forces, unless racing at modern speeds (over 200 mph at the top level).

FWIW even MotoGP has an electric race series. And there has been an electric TT for 9 years, now lapping at 120 mph but they only do one lap because of battery capacity. Top electric speeds must be near 200 mph now, on (closed) public roads.

50 E-Bikes though some may never make it into production of any volume. The French Postal Service seem to be using E-trikes in Cities like Vichy. Delivery vehicles are an obvious choice - and we did it years ago with Milk Floats. Lundun should lead the way, but Lundun does wot Lundun wants!

Mr. Red.
I'm just saying that torque reaction is a different phenomenon from gyroscopic forces and dealing with them.
For instance in a 4 wheel car, you can (and do) notice torque reaction when accelerating. But I doubt that anyone other than possibly a formula one racer, is going to notice gyroscopic forces because vehicle weight is far above spinning mass of the wheels and tires. On a motorcycle particularly a racing motorcycle, I expect there will be a noticeable gyroscopic effect. Torque reaction direction will depend on whether the drive is a shaft, such as BMW, Moto-Guzzi and some Hondas, and a chain drive like almost anything else.

I remember seeing a tractor trailer with a heavy load trying to get into motion after a light turned green. As the driver let out the clutch you could see the left front tire rise up by inches, then pound the pavement, up down up down as the drive shaft contributed great torque from the engie to the drive differential.

I'm a little confused, Mr. Red.

You habituate to it. Taking nuerologically: your system 1 just does it and doesn't trouble system 2.

If you accelerated hard at the apex you would notice it when the bike was new to you, because your system 1 had not habituated. And any new machine puts your system 2 on alert to reason what is happening.

FWIW the brain operates on two levels which psychologists refer to as System 1, the intuitive brain which runs on experience and System 2 is the much slower logical, reasoning part of the brain that collects and figures new experiences, unless system 1 has already dealt with the problem. And con men know this and prime peoples' system 1 with words and actions.

Torque reaction on front wheel drive cars can be easily felt on loose road surfaces, but I think that is caused by the joint that allows the drive wheels to point left & right (eg Universal Joint). It is the acceleration that does it, not constant speeds. Much like traveling at 100 miles an hour is not felt but accelerating or breaking is noticed.

I'm a little confused, Mr. Red. I was on a BMW with a shaft drive, there was undoubtedly some sort of torque reaction when feeding the engine gas, but in a banking motorcycle turn this is usually minimal, and I can't recall noticing it. When banking spinning wheels, there is a gyroscopic counter force, but I never was able to separate it out. After all, the engine frame and transmission were together far more massive than the wheels, and the reaction there was too subtle for me.

There have been and may still be flywheel temporary power systems, the presentation I saw over ten years ago was for an industrial quality unit, quite heavy of course, which could provide power to supply peak electrical demands. It was useful for a few minutes at most to accomplish what is called 'peak shaving'. As a means of mass automotive power, it is a non-starter, pun intended.

flywheel ....... It could also tilt for corners.

The Swiss tried that, spin topped-up at bus stops. Bus, had 2 contra-rotating flywheels to avoid the tilt in the wrong directions. Broke its back on a hump-backed bridge. AFAIK they only made one in the 50/60s. Probably fatigue from many similar changes of pitch &/or turning at speed.

Torquing of flywheels. Ever driven a boxer motorbike (shaft drive - engine & shaft longitudinal)? Accelerating round a corner causes a torque reaction - either into or against the corner. You do get used to it. Walter Villa campaigned a BMW boxer with the engine upside down, early on. He was good enough to be a 250 & 350 World Champ on a more conventional bike. 60's/70's era.

There was a British bike that had the (transverse) engine rotate the non-conventional way and the flywheel effect either worked against corners at racing speeds - &/or riders never got used to it.

Flywheels can exert a lot of force in the "normal" direction, if they are used to extract energy.

The hydrogen fuel cell is the future.

On that logic, Betamax was a better format. So what happened?

The answer is "content", it produced momentum. Better is not always the way the world works. The world wants it** NOW. And they have it in their own home. The distribution is already in place across the world. And with existing technology/manufacturing PV is available NOW at reasonable cost in areas where distribution petrol &/or electricity is expensive. And Electric cars might serve as a reservoir of electricity for the home &/or grid. Something hydrogen can't do. And hydrogen needs energy to manufacture, which will be electric. And power is power, why add one more translation and, an as yet not available, distribution network, with many caveats on storage/safety.

Hydrogen has a lot going for it, except for a soupçon of reality and sheer momentum of the competition. Electric has issues but it has the NOW factor. Compressed air has a lot of pluses, not the least the tech is understood & there (ish) in every filling station, but no momentum.

If anyone here can predict the future - would you PM me with some sure fire lottery numbers.............

Hydrogen can be produced by the electrolysation of water. You know that all that renewable electric power that is produced when nobody wants to use it? It could be used to produce hydrogen which could be used to power personal transport. If there is not a will there wont be a way.

I don't do many gigs at all these days. I've always only done gigs I can get home to at night. I did a few tours when I was younger -but that life doesn't suit me at all.

No, my main need of a car is for my wife who is disabled with fheumatoid arthritis. I need it for shopping; for little outings for her and hospital and doctor's visits.

Nowadays I do less than ten thousand miles a year.

I buy my cars at the auction block these days, as cheaply as I can. This present car is fourtenn years old - although some of that time - I ran two cars - and a campervan at one point.

I just wondered if I bought a car that was non-hybid, or electric - an ordinary petrol car - if it stands to be made illegal anytime in the next few years.

The only thing against the all electric for someone who wants to be 'seen out' is: it requires some adapting/ learning/ familiarization. Electric cars have a different feel, and are so quiet you might not know they're on. Since they are all automatic, one has to become accustomed to the digital interface which behaves differently than the old style. For instance, in the old days, a few years back the individual switched the headlights on or off. I've been driving a Chevy which automatically turns the lights on when it thinks they're needed. One can control the overall on or off by knowing where the master light switch is, otherwise the Chevy defaults to automatic. Now I've got a Toyota which has the manual 'on', manual 'off' AND automatic setting all on the same control stalk. When one gets their car serviced, the shop may not leave the controls the same way. All through the winter I saw cars driving with no headlights, and this is because the folks inside were depending on the automatic setting which was no longer set to automatic. Hope this makes sense.

Stanron, where do you think hydrogen fuel comes from? Most of the time it comes from natural gas which has been passed through a reformer. That means all that waste material in the non-hydrogen part of the gas still needs to be dealth with. You need to research why the world has not gone to fuel cells if they're as ready as you say. They are not. And if they're ready, they're not clean.

It IS a great time to be an engineer!

Big Al, how much do you drive?

A friend in her early 80s is thinking the same way as you; she's considering something like a Leaf +2, I think it's called. Her logic is that the tax, insurance, NCT (=MOT), maintenance and parts, parking and petrol - even for the very little driving she does - on her big old car is around €8,000 a year, and so it's worth her paying over €30,000 for an electrical car which will have no NCT, free fuel and relatively little maintenance (because new).

However, she'll in fact be replacing two diesel cars with one electric, making the cost/benefit even better.

And she figures an electric car will, as she depressingly puts it, "see her out".

The other advantage of getting an electric car when one's becoming old and decrepit is that it's effectively an automatic, so you learn how to work it fairly easily, and have less in the way of complex unconscious decisions to distract you while driving.

If the decision were mine (I've long since given up cars; I can hire a car if I really need one, but mostly ride the bike and on the rare occasions when I really need a lift, kind friends help me out) there's a system called Go Car in Ireland - I suppose it's probably international - which allows for occasional hires that aren't too dear.

But it depends on what you want to drive for. If you're going to late-night gigs far away, yes, you need it. If it's shopping, you can ride the bike for some and get deliveries for other shops. I'd really be inclined to plan out exactly when, where and why you drive every week before making this decision.

Diesel electric has been a standard in UK trains for what seems to be forever. The Top Gear team under Jeremy Clarkson made one and, of course, it wasn't a thing of beauty. It would enable an electric car to travel more than fifty miles, and it would allow a viable heater in winter but it would be a polluter, it would have to have a fuel tank and a radiator, a starter motor, all the stuff that an electric motor doesn't need.

The hydrogen fuel cell is the answer. It's obvious.
