      While I too do enjoy eco-friendly technologies, I do have to wonder if this will actually pan out. Given your average joe goes to work between 9-5 (the hours the sun is up), the solar concentrator would have to be at a place of business to be of any use other than on the weekend. I cant imagine what the interior of that car must be like or even the door handles, steering wheel after sitting for several hours. While the concentrator is certainly a way to improve the collection of energy, I have to wonder how long those panels will last at the higher operating temperature. All in all it's nice to see an automotive giant like ford producing eco-friendly vehicles, but it seems a bit half baked.

          The enormous expense of the solar panels and the lens system, to get the propulsion equivalent of £2 of petrol? (Assuming 60mpg). Presumably not on dark winter days either.

          And even if you want to go electric, you could get the juice more quickly and cheaply from the mains - government renewable subsidies notwithstanding. And to get the subsidies, you need the solar panels on your house, not your car.

    Concentrator? Why bother?

    If you're going to go to all the trouble of building a shelter with lenses etc, why not just put PV panels on the shelter and then plug in the car? That way any leccy car can use it and when you're not charging cars you can feed the power generated back into the grid?

    1. Charles 9 Silver badge

      Re: Concentrator? Why bother?

      I imagine, for one thing, that would require larger and more expensive panels instead of employing physics to make do with less raw materials. Then again, perhaps take both ideas: put a large collector on the roof AND place a Fresnel concentrator on top. Nice thing is, since this is a fixed installation, you can make sure it's optimally oriented for a given location and allow one or both to track the sun through the day.

      Having said that, has anyone got news of progress of handling the big problem of NIGHT operations?

      Fresnel concentrators are embossed plastic.

        Re: Concentrator? Why bother?

        Er - no. You put the panels on the roof of your house. You put the lenses on the panels.

        You run passive solar pipes under the panels to heat your water and keep your roof from catching fire.

        If you're really adventurous, you pump the heat to a store in the ground under the house for winter.

        You run the panels to the usual battery, which not only turbo-powers your house because your PVs are producing something 2-3X the usual W on average, but can also charge your car at night.

        Putting fresnel PVs on just the garage for a car with a range of 21 miles makes no sense at all.

          "You run the panels to the usual battery, which not only turbo-powers your house because your PVs are producing something 2-3X the usual W on average, but can also charge your car at night."

          The problem with that is there is NO such thing as "the usual battery" when it comes to powering a whole house for say 16 hours at a time (dead of winter in northern latitudes = reduced sun hours, and those sun hours are oblique and weak by comparison). Current tech is either too risky (Lithium-based batteries run the risk of spontaneous combustion, lead-acid ones can distort and/or leak, and NiMHs suffer memory) or too bulky (again, the lead-acid situation). And since compact, safe, powerful solid-state storage has been in demand since the invention of the laptop computer, there's been no shortage of attempts to build a better battery: with only incremental steps to show for it when a giant leap is needed now to make powering a house without a generator practical.

            But why are you evaluating the fitness for purpose based on the far end of the usage curve? Thats the ending point not the starting point. If you get to a solution that works reasonably in summer but only partially well in winter - providing the econimics stack up its still a win.

                Re: Concentrator? Why bother? @ Charles 9

                Not just a car, but a house, too. In such a scenario when the basic goal is 100% power coverage throughout the day (a fully self-powered house, IOW), the primary design philosophy would be, "Plan for the worst." In other words, plan conservative and base your situation on the worst-case scenario.

                In that case, the worst case would be a blizzard on the winter solstice (shortest day of the year and most oblique sunlight which is in turn obscured by thick clouds and lots of snow, some of which is bound to cover the panels) plus one adjacent day. If the combination of solar collector and battery storage tech can handle that scenario, than any other scenario it encounters is likely to be easier, making the entire system viable long-term.

            Lead-acid batteries have a long history of working with home solar and wind systems (and they're popular on sail boats, too). And while lead acid batteries heavy, they're not bulky for the kilowatt-hours they store. A battery box about the size of a standard server rack could easily store 30 to 40kWh of lead-acid batteries, and house the switching gear for a whole-home UPS / solar charging system. The following link is a typical selection of lead-acid batteries for solar systems. You can Google up plenty of other lead-acid batteries for renewable home power storage with searches like: solar lead acid; solar deep cycle battery; solar battery box; etc. There are lots of vendors out there.

            http://www.sunwize.com/documents/sunwize_solarready-nomod_8-08.pdf

            A 26kWh battery box, as offered by Sunwize, will deliver 1.625kW continuously over 16 hours. Homes are typically approximated as using 1kW on average, so that's enough to cover 16 hours of darkness. (Despite the name, I'm sure Sunwize's switch and charging system will work fine with home wind turbines, too, so you don't necessarily stop battery charging when it gets dark and stormy.) Just make sure your foundations are up to the task because the lead-acid rack will put nearly a ton on a small 58" x 15" footprint.

        My old XMs had plastic fresnel lenses in the headlamps to achieve the then-mandated beam cutoff.

        They're absolutely excellent - for about 3 years, then the plastic becomes increasingly opaque.

        In Spain

        The problems in Spain are: Very few people have access to parking that can see the sky. Normally you are all shoe-horned into a skyscraper with underground parking. There are some people living in villages that still have individual housing, but normally their disposable income prohibits buying cars like this.

        If you do have above-ground parking, it has a shade, because otherwise the paint on the car doesn't last 5 years, and your hands melt on the steering wheel. You could possibly remove the sunshade for this car, but then you'd use a lot of your 8*300w of "free eleccy" running the aircon to cool-down the car. (Sunpower claim that their best panels are 21.5% efficient, so in Spain you are looking at 8kw*0.885 = 7kw of heating!! a fair amount of that will probably end up inside the car)

        You pay through the nose to have an electrical supply to your dwelling that can push more than 3kW. If you actaully have more than 10kW available, you are effectively non-domestic and can't get a tarrif which is limited by the government, so the leccy companies can charge you whatever they want. Also you probably don't have any way of getting your electrical supply down to your parking space in the garage. I hope that the charger is intelligent to only consume as much power as you have available at any moment in time.

    21 miles from a full day's charging while having to put up with a fugly and pricey roof-full of PV and also having to build a car-sized lens in your garden? And this is progress how, exactly?

    1. lurker

      Look at it this way, if you typically used this car only for short journeys - e.g. the school run, it could effectively be free to run. Pretty sure you can see the point of a car which doesn't require petrol?

      Obviously, it's not going to work for everyone.

      1. Andy Mc

        But if solar is the answer, then surely the way to do that is centralised, large-scale, high-efficiency with distribution, allowing individual peaks and troughs in demand to be absorbed. If it charges within a day and you don't use it for 3 days then you've wasted 67% of the generation potential because you don't have the batteries to store the energy. (Perhaps you should go for a drive, just to justify it). If you're only using it for small distances then it seems unlikely it'll pay back vs. getting someone else to generate the energy efficiently for you.

        I really can't see how this wins vs. a plug-in?

        (oh and for the school run, the answer is walking)

        1. Charles 9 Silver badge

          The problem is that distribution can itself be inefficient. Plus it introduces the points of failure and failure cascades that our current centralized system can bring. The idea behind solar-panel houses is to DEcentralize the grid and allow each unit to be capable of powering itself if need be, plus if any one unit fails, none of the others have to rely on that one, helping to prevent a failure cascade.

  8. imanidiot Silver badge

    It's clearly a concept developed without bothering to take practicality or cost into account. As said, why bother building a big heavy expensive shelter that can only charge that particular car? Putting more surface area of cheaper panels on the whole roof of the house and/or shelter is going to be much more efficient.

    I know The Reg is based in the UK, but this is a Ford concept out of the USA, where there's no shortage of space (in most, but not all places) for parking & building concentrators at home or at work. There's also no shortage of sunlight for millions of potential buyers there.

      Mnay US residents, like many UK residents, live in heavily urbanized areas. In these areas most people can't street park their cars even assuming they've got sufficient sunlight vis-a-vie the weather. If you're not in an urbanized area the 21 mile range kills it. What you've got is a market for maybe 100,000 people all across the US, including greenies with too much money on their hands.

      I am curious why you don't see the train technology in hybrid cars. There doesn't seem to be any 'proper' diesel electric cars; they are all encumbered by complex and heavy drive trains.

      Hook a diesel engine running at optimum revs to a generator and a small battery. Wire this to wheel hub motors. You can ditch the whole transmission system and you get regenerative braking and a serious range of traction control options.

      I suspect that someone has a patent somewhere that's buggering the whole thing up. Or I have missed something obvious...

        http://en.wikipedia.org/wiki/Hybrid_vehicle#Series_hybrid

        I believe the existing issue is powerful enough electric motors that can completely replace mechanical drive train. I believe in the current generation of cars, combustion engine cuts in above a certain speed.

      2. Tom 13

        Re: Or I have missed something obvious...

        Yeah, you did.

        Most importantly: The diesel still puts CO2 in the air, which is what this is really all about. And any CO2 in the air doesn't meet the pure Ikarran definition.

        On the business end you have issues with retooling, gathering new vendors, and updating all of your existing lines of vehicles. It might be possible for a start-up to try that route, but a start-up won't have the distribution channel. So it becomes a chicken and egg problem.

    2. ForthIsNotDead

      Re: Would like to see this tried on a train

      I wouldn't recommend that. Without something to secure the car to the roof of train it would almost certainly fall off. And even if you could secure it, you're going to be on a sticky wicket as soon as you encounter a tunnel of any kind.

      I'd leave it if I were you.

      Re: Would like to see this tried on a train

      I think scale's the big problem. Trying to scale down the D-E train tech down to a car's frame seems to reduce its power too much. Most cars have only two axles whereas the average locomotive has four or six, plus most cars only power one axle (more power axles = more power at the expense of needing more space for the motors). The shape of the car would help determine if you could do two direct-driven power axles as well as how big you can make them (larger motors allow more electromagnetic force, equaling more power).

      And that's assuming axle motors (which is what trains use). Individual wheel motors change the math such that you can't rely on train tech as an analogue.

          Porsche was making a petrol-electric car with hubcap motors in the first few years of the 20th century...

          Various manufacturers have played with these, though I don't know of any besides Porsche that put them into regular production cars.

          The main issue with wheel-hub motors is the increase in unsprung mass, which has two bad effects. First, it increases moment of inertia, so more torque is required to accelerate the wheel's rotation in unit time, increasing time/distance to a given speed and braking distance. Second, increasing the unsprung mass also increases the force required to accelerate the wheel linearly, notably up-and-down for road-surface irregularities. That means more stress on tires, suspension, and chassis, and a generally worse ride and handling.

          For that reason, a lot of people have suggested a motor-per-wheel, but not mounted on the wheel itself.

          But according to the font of all knowledge, Michelin had good results replacing the brake rotor with the motor.

          I'd like to see a four-wheel diesel-electric or gasoline-electric vehicle myself. Personally I'd be more than happy to return to the performance characteristics of 1980s small cars, in exchange for the considerable improvement in efficiency from always running the combustion engine at peak efficiency and losing the weight of the transmission. But I don't think there's a sufficient market for it.

          On the other hand, Michelin's Active Wheel produced about 40 hp per wheel. 160 hp is way more than '80s-era economy cars had. The 1988 Toyota Tercel hatchback that I learned manual-shift in had a whopping 78 hp total; two Active Wheels would be more power, plus we'd get rid of that transmission. And that thing was plenty nimble in the city, where maneuverability counted a lot more than straight-line speed.

          Damn. Now I'm contemplating a mid-life-crisis project.

    Reasonable quality fresnel lenses will go around a hundred bucks for a 10" x 10" so for an average car port of around 15 square metres of roof you will be looking at about $30.000 just for the concentrator, add the price of the horrible hybrid and then try to figure an ROI!

    The thing is a joke!

    At the Equator when the sun is perpendicular to the ground at noon there is the potential to gather 1.1 Kwh/square metre as the sun rises and falls at either side of noon there will be correspondingly more atmoshpere between the sun and the ground so less energy as it is adsorbed by the atmosphere, it's basically this effect that causes winter! if Ford say this is turning out somewhere near 30% efficiency (300 watts and as with all PV it falls off over time) they are talking midsummer, in more northern or southern latitudes the figure will fall off and in winter will be even worse.

    Kudos to them for researching and developing but to try to sell this idea at the present level of development even as a concept is laughable. They should just be saying ' This is where we are at so far we will keep trying'

    I call this MS syndrome a la Vista and Win 8: If you keep saying it is good for long enough maybe some one will believe you.

      Are we talking glass or polycarbonate? Linear beam or spot beam? We may also have to allow for quality variances. I mean, it doesn't have to be perfect. Most of the lenses I've been seeing in my research do achieve at least an 8x rating even with minor imperfections. A large linear fresnel lens with a 8-9x power isn't likely to be as expensive as you describe, making it more viable.

        But what happens on a sunny day when the car is not parked underneath?

          The house gets a good charge since I'm talking putting this concentrator over a solar collector installed on the roof of a house and tied to the house's grid, NOT the car, which could instead tap into a lead coming FROM that collector.

      I think you'll find it has to do with the angle of the sun, less light falls per given area just on this effect alone.

      At noon on the equator with the sun directly overhead a 1 m^2 shaft of light illuminates 12^2 of surface, at sunset the same 1 m^2 shaft of light is spread over a large area of land ( depending on the topography)

      Really? I could have sworn winter was caused by something to do with pomegranates.

      Or at least with something being spherical.

      (And I might note that you all are lucky I put up so many holiday lights. I'm convinced they tempt the sun into coming back. I've been doing it every year, and every year the sun returns, so...)

    Wait. Is it not easier to put this IN the petrol stations, for drivers to just pick up a battery. Solves the "my car is parked in a garage" problem plus the "oh my these solar panel are heavy" and "it rains here".

    But never mind, it's all about the illusion of something "helping" when the elephant in the room is, it's a "hybrid", or should that be "petrol engine all along, but we promise, we put a little battery on there for occasional (possibly fossil fuel produced) electric use". :/

      Lets see, sun intensifier near to volatile petrol fumes......yep, that'll get cars moving pretty quickly.

      Unless you are thinking about the Israeli company that allows you to drive up, drop out your nearly empty battery and swap for a fully charged one?
