England To Test "Electric Motorways" 74

Posted by samzenpus from the charge-on-the-go dept.
DaneTerry88 writes: Highways England plans to test under-road wireless charging equipment that could be buried beneath motorways to top-up cars as they drive. Charge-as-you-drive technologies have already been used in the South Korean town of Gumi. The town has a 12km (7.5 miles) route that allows buses to be charged as they drive over it. In a press release the agency says: "The trials are expected to begin later this year following the completion of an ongoing procurement process. The trials will involve fitting vehicles with wireless technology and testing the equipment, installed underneath the road, to replicate motorway conditions. Full details of the trials will be publicised when a successful contractor has been appointed."

    Think of the Big Brother scenarios . Presumably cars will have to be fitted with some sort of identifier so that drivers / owners can pay for the charging in some way.

    So while its a great idea - Id want to know whats happening to the data about my driving habits!

      There are Automatic Numberplate Recognition cameras stationed on roads all over the UK. Cars are tracked across the country, except in the most remote locations. Even tax discs are not necessary anymore, because systems attached to the cameras check that your tax+insurance is up to date as you drive past.

      To clarify, every road user in the UK has their movements monitored with a fairly fine level of detail by government.

        • If 1 in 4 drivers are currently uninsured it appears the cameras are not there to prevent uninsured motorists. Or they are failing miserably at it.

              I've suggested a fairly straightforward approach before, as we have a lot of problems with insurance here too... When conditions prompt an officer to confirm the paperwork for an automobile and driver, if two forms of paperwork are not in-order then the car is impounded. So, if the driver cannot produce both current proof of insurance and cannot produce a driver's license, or if the insurance and the vehicle registration are both expired, or if the driver's license is suspended and the registration is exp

      Efficiency is not a big advantage of electric cars. All things considered, electric cars are not much more efficient than cars with internal combustion engines. The big advantage of electric cars is that they don't need fossil fuel. Electricity can be created from renewable resources. The big disadvantage is that storing electricity in batteries in the car is expensive and also makes the cars very heavy. "Electric motorways" don't remove the advantage of not needing fossil fuel, but do reduce the disadvanta

  • I thought wireless charging was inefficient. A quick search over the internet shows me claims of between 50 and 70% efficiency on power delivery for the mobile charging standard Qi. As for automobiles, I like the following graph, but I cannot tell how true it is: ecoupled-infographic.png [hooniverse.com]
    Please note that charging may behave differently while in motion.
    • It seems reasonably accurate - perhaps conservative these days. But 20% of losses is not a big a deal if you have a potential oversupply of cheap electricity and you're taking battery wear into consideration. For example, if a car battery cost $10k and lasted 1000 cycles with 200 miles per cycle, and you were to drive 100 miles on a roadway, you could either pay $0.5-1 for extra electricity...or you could wear out $5 worth of battery life.
      • We're talking about energy losses here. Energy which is either polluting or which is clean but we can't make enough of it to supply the demand. How is energy loss even acceptable in this day and age?
        • You don't think that extra manufacturing to compensate for the inability to consume electricity directly is cheaper in environmental impact, do you? There's a reason why money generally works - it does roughly correspond to expenses of all sorts. If you think ten times greater industrial expenses mean a better alternative in any environmental aspect, then I'm not going to agree with that. The extra PV panels will have a lower impact than the extra batteries, unless automotive batteries somehow increase thei

      Road widening? While I suppose collecting yet more data on the phenomena known as induced demand might be fun and all, there's probably more sensible transportation investments to be made than laying down yet more expensive tarmac everywhere.

  • Shame that driving on motorways in England has become tedious as hell now that they're installing average speed cameras everywhere. Slip over the the paltry 70mph limit a few times and you get banned from driving for a year. I try to avoid the motorways when driving nowadays.

      The idea with speed limits is not only to make people go slower, it is also to make most people go at the same speed.
      This has several benefits, including :
      - safety, by reducing the relative speed between two vehicles
      - lower congestion, by limiting the need for overtaking and speed changes that can cause waves of traffic jams.
      The 70mph limit was probably selected because it is close to the speed most people would drive naturally and serve as a baseline for road design. The speed itself is not that important,

        Because 70 is too goddamn slow. Have you ever driven on a British motorway? 70mph definitely isn't the speed people naturally drive at in good conditions; it's frequently more like 90-100mph and yet motorways have the lowest accident rates of any roads.

          The reason is that with my car, the small time gain doesn't make up for the lower fuel economy.
          So yeah, some busy people with nice cars may be comfortable driving at 90-100 mph but it is not a majority. The road is also shared with trucks, trailers, not too powerful cars and drivers who value their fuel economy.

    First, powering wireless while driving is extremely expensive, as large portions of the road must be equipped with coils. This approach is also very resource hungry and therefore not applicable. Second, installing such coils for parking or on traffic lights is also expensive and complicated, as they have to be switched on and off 100s of times every day. Third, cars are by concept very inefficient, as normals cars weight 1-2 t and are used to carry around 1.3 persons weighting 80-120 kg. 1:10 to 1:20 ratio. In addition, they require a lot of space. While this is not a problem in large areas of North America, it is a problem in densely populated areas, like Central and Western Europe, and even more in India, China, Japan, etc.

    The solution to present day transportation issues in metropolitan areas, where most people live, are public transport. Well implemented, it is faster than cars in traffic, they require less space than cars, and they require less energy. In addition we should promote bicycles, as they are more flexible and a good short range people mover. They also come with the bonus of better health. The individual traffic (with cars) is dead, as there is no individuality in traffic jams and when thousands of people all drive in the same direction every morning and back in the evening.

In such areas mass transit by tram or even by bus is not easy to realize because you need a specific amount of people to make the system work. However, when the population is denser which is in fact the case in poorer communities in the US and applies in (Western) Europe to most bigger cities.
