    One word to describe it

    FUGLY!

    Also the idea of hydrogen is stupid. You need to get it from somewhere, yes? Oh, let's use electricity! From coal burning power stations as there's nothing else around. It's little inefficient? Happens, in 30 years we will get there. And kill Earth in the process.

    Electric cars are slightly better. It's not that those are mighty effective, but at least are cleaner (on the spot, not general) and quieter. If only batteries were cheaper...

    £200 per month for 20 years?

    That's a bit ambitious isn't it? Do they really expect it to be worth £200 per month in 3-5 years time never mind 20?

    It's this reason the Ford Focus and not the tonka toy Smart car is the most popular car in Britain.

    Why bother with a 250 mile range when you can't even get a bloody suitcase in the boot.

    Capacitor charging

    Your article missed the good bit...

    The small fuel cell will charge the ultracapacitors during driving - so although the 6kW fuel cell alone will provide pitiful acceleration, it will be able to maintain a cruise, and charge the capacitors during lower power usage.

    So - you turn the car on - the fuel cell charges the capacitors, and then you hit the pedal and the capacitors provide a surge of power to get you moving. Once moving, the fuel cell keeps you there. And when you brake at the lights, the regenerative braking charges the capacitors, ready to move off with another surge of power when the lights go green.

    Which is basically a sensible answer to the "pitiful fuel cell power output" problem. Cool!

    Please tell me I read that wrong...

    "Instead of selling the RUC outright, Riversimple plans to lease out the car over a 20-year period for around £200 ($327/€236) per month – a price that will include the cost of the hydrogen."

    Thats £48000 by my calculation? And a 20 year contract? Thats worse than the iPhone!

  9. Simon Neill

    Expensive...

    £200 * 12 months * 20 years = £48,000. Even with fuel included that seems a little high for such a small car.

    6kw

    I don't want to sound negative, but 6kw (about 8bhp) isn't going to accelerate anthing very fast. If, with two adults and some luggage on board, this thing weighs (say) 500kg (assuming the ampty vehicle is about 320kg), then at 30mph that's almost 90KJ of kinetic enery, or about 15 seconds of acceleration at 6kw even with 100% efficiency and neglecting losses due to friction, drag and so on.

    So I very much hope that those capacitors have got the means to provide considerably more than 6kw peak power output, or we have something much like a G-Wiz in performance, albeit it considerably prettier.

    The peak output of bettery powered cars is something of an advantage in acceleration, not to mention the abilitiy to store off-peak and intermittent green power sources. Of course that can be done to generate hydrogen too, but the end-to-end thermodynamic efficiency of the hydrogen cycle is atrocious. By the time that losses in electrolysis and compression are taken into account, you'll be lucky to see 30% of that green electricity delivered at the wheels vs perhaps 80% using batteries.

    Anyway, not a bad idea as a city run-about and it does get over the range and kerbside charging issues of battery cars (assuming refill stations are available). However, surely nobody is going on a long journey with one of these. Show it a moderately steep hill and, two-up, you are going to be lucky to see 15-20mph. 6kw is enough to lift one of these things just over a metre per second. On a one-in-ten that equates to perhaps 25mph at most two-up. If it's one-in-six then halve that...

    The energy required to produced hydrogen is greater than what the hydrogen itself can produce. And the energy in their production comes from the national grid and other fossil fuels.

    ...they will have to add all the safety requirements, crumple zones and side impact bars that are required to make the car road legal, or at least crash survivable. After that, you can halve the range and accelleration. it can be done, re: the Smart car.

    Puzzled

    I'm puzzled by this.

    For a start is 6Kw really enough to ensure a 50mph top speed? Even if it is it doesn't sound like the acceleration will be up to much. With a couple of adults on board the weight will be 500kg or more, that gives a power to weight ratio of something like 16bhp/ton. Hardly enough to pull the skin of a rice pudding. If there's one thing that is necessary to keep you safe in a small vehicle in urban traffic it's sprightly acceleration, something that 16bhp/ton will not give you.

    The next puzzle is the use of the word "recyclable". It's a marketing weasel word if ever I heard one. While these materials may be recyclable, so are most materials if you try hard enough. Saying they are recyclable tells us nothing about the damge done to the environment by their manufacture. If this thing wants to claim to be truly green then it should be made from recycled materials. It's interesting that most of the steel used in the world these days is recycled in as much as scrap metal is the main constituent in it's making. Wasn't there a story years ago that Fiat used steel from salvaged shipwrecks bought from the USSR? We don't hear car manufacturers shouting about their green credentials in using recycled materials do we? On reason for this could that the biggest harm done to the environment in making steel is in the smelting, not digging the raw materials out of the ground. So the question that needs to be asked is: What are these "recyclable" composites and what harm is done to the environment by their manufacture? If they are not willing to tell us then they can shut up about the materials being recyclable, it means next to cock all.

    Another puzzle is the spec. It's designed for urban transport and it's pigging slow. So why brag about the 240 mile range? Surely that's not something their chosen target market will be bothered about.

    My final puzzle is who they think their customer base is. Economical two seater vehicles are available today, but they are hardly popular. So have they discovered a large untapped market or are they deluding themselves?

    Re: Looks nice but it is NOT GREEN

    "The energy required to produced hydrogen is greater than what the hydrogen itself can produce."

    ...well, duh?

    "And the energy in their production comes from the national grid and other fossil fuels."

    ...again, well duh?

    What were you expecting from the poor molecule - a violation of thermodynamics?

    Both hydrogen AND battery-powered cars are intrinsically useless unless the power grid makes a massive switch away from fossils. But this fact is not new, not surprising, not fixable by tech advances, and not a sufficient reason to reject hydrogen or battery-powered cars. Build the damn nuke plants already, then truly green cars will be actually possible.

    To Little Too Late

    The car is too small, too slow, hauls too little and as Honda found out with their Insight hydrogen car, can't go very far if the fuel isn't available.

    Again a company spends a ton of money on the body design when the drive system is what really counts and they messed up on both counts.

    Pity

    About the lease, that's a sad deal breaker for many as it's just too expensive. As for missing some boot space, the average working person can live with that as they only carry a briefcase and laptop around. For them this vehicle is a nice city hopper.

    I'm personally more interested in the generator part of this vehicle, and wouldn't mind seeing a similar, slightly scaled up (in relation to vehicle purpose) version appear in more electric vehicles.

    Fuel fools

    This is cool, but will flop because as much as we'd like nice economical cars, we like acceleration and lots of space.

    The landrover brigade will always get the next 4.6L eco smashing monster, then will never put anything bigger than a pair of (mud free) hunters in the boot and claim they need it tat big so little tarquin and his friends have plenty of space in the back.

    But this is just everybody else on a smaller scale, we don't want the inconvienience of having the £29.99 B&Q BBQ delivered because we can fit it in to the car etc.

    I don't run a car (I have a motorbike), I get shopping delivered and hire a car when I really need to (taking daughter to Uni etc.), quite frankly it's a pain in the arse, and if I could afford it I'd get a nice mazda 3 or 3 series BM, £200 a month (all in? insurance?) is OK but when you can pick up a car that will last 12 months for less than a grand, why bother?

    This car will be bought by people as a second car for work commutes (instead of sharing or using the bus/train), this won't help the environment in any way, and will probably make it worse, it will only become a good idea when it becomes the ONLY choice.

    20 years is insane

    Hands up how many have got a car that's lasted 20 years? If it really goes it looks like it might last 10 - of course by then it'll be totally outclassed by other cars in development, so won't be particularly efficient or clever by then.

    Just imagine yourself in 20 years driving on this thing that can manage 15mph on a steep hill, being shouted at by all the younger drivers doing 40+ in their nuclear powered hover cars. It aint pretty.

    Electricity->Hydrogen->Electricity.

    Less efficient that

    Electricity->Chemical Potential in Battery->Electricity.

    So more expensive, less opportunities to fill up, less efficient and clearly a death trap in an accident.

    I admire the attempt, but until those crazy nanotube hydrogen storage materials are commercially viable then hydrogen is not going to work for anyone. Already have a majority of the infrastructure needed for electricity.

    Welcome to the Second Law of Thermodynamics. If only we could invent the perpetual motion machine.

    The thermodynamic efficiency of the hydrogen economy is disastrously bad. It only works if the electricity is available really, really cheaply, and if you can use batteries then it's generally more efficient.

    Horses for courses...

    According to the press release:

    0-60 time = err, never (top speed is supposed to be 50 mph)

    But then driving a sports car through rush hour London traffic results in a larger than necessary petrol bill, a sore ankle and never attaining more than 25mph so 0-60 is pretty irrelevant. Perhaps that's why they called it an 'urban demonstrator'.

    Riversimple suggest that the 'well-to-wheel' emissions should be ~30g/km including all the conversion losses (based on forming hydrogen from natural gas) which still compares well with just the tailpipe emissions of a Smart or similar.

    Minimum lease term is suggested to be three years (not 20). However, the cars are designed with a minimum 20 year life expectancy.

    But perhaps we should not let the facts get in the way of a good moan.

    The real answer...

    Is to keep the chasis and wheel motors, sell it outright instead of lease it, and allow the buyer to drop whatever power source in it they want, batteries, fuel cell, whatever. I, for the forseeable future would guess a conventional (or turbine) engine and generator would be best.

    Bunk

    First, the fuel cell alone costs more than 48,000. This can only exist with that MASSIVE government subsidy of $20M to build the 10 cars....

    Next, great, it included H2... But how about those membrane replacements for the fuel cell?

    I'm assuming it's using liquid H2 as well, either pressure compressed or frozen to rediculous temps. It's going to take a lot of electricy to maintain that density of H2, or 6-10 hours at a pump to fill it up. (a common issue with ALL H2 powered vehicles).

    50MPH is barely usable as a commuter car, on city streets only, no freeways. It can only go where mopeds go... Why have a 240 mile range? ...and how are you going to get to the pumping station without getting on freeways in most places? The car will never be able to go more than 50 miles from it;s home in most cases....

    Scientific Illiteracy

    Not just the makers, not just the journalists but also a significant number of those commenting here. Hydrogen is not produced by electrolysis from water.in significant quantities. It is produced by passing hydrocarbons and steam over a catalyst ro produce hydrogen and that good old favourite carbon dioxide which is vented at the production site. The car may emit no CO2 at the point of use, but it emits just as much as any other vehicle of the same size/weight/power.

    As to the value of this car, it's hype, hype and more hype. For the £200 a month touted as the lease cost for this car one could have either a proper car suitable for four to five adults or a Smart CDi with sufficient fuel for 3000km of driving. The Smart car is functionally identical, except it's faster can be driven safely on a motorway and I suspect that an environmental audit would favour the Smart car.

    -Bracket to gearbox casing to 'bolt on electric motor'

    -A standard modular based lithium battery pack(s) (ideally where individual cells can be replaced).

    -Welded or bolted bracket(s) for holding said batteries.

    Seriously how differiult is it to replace engine with motor (say 6 - 10KW motor), DC to DC control box, regen braking system and batteries and if there were a standard size battery packs used by all manufacturers then the prices would be driven down - I suspect though that electric car prices will be kept artifically high for a while though.

    1) by cleverly using ultracapacitors, one avoids the need to haul around a 500+ kg propulsion or energy storage unit - as with a normal or a battery car. Through this and the general light weight, energy demand is minimised.

    2) can one not make hydrogen using off-peak electricity output, which I vaguely gather is cheaper because it's surplus?

    My car gets well over 360 miles on a single fill-up. And it has good acceleration, a max speed in excess of 120 MPH (not that I've ever gone that fast, too many radar-equipped coppers around here), it costs a whole lot less than £200/month, and can carry five adults (six with some squeezing) and a fair amount of stuff in the back... but it's an Evil Petrol-Burning Anti-Gaia Device. I'd bet that it actually produces less CO2, though, once you allow for the real costs of generating that hydrogen.

    Hydrogen will always be a better option than batteries if the infractstructure is built to exisiting petrol filling station to provide hydrogen, fill a hydrogen cars tank will take a few minutes and you off on your journey again.
