England To Test "Electric Motorways" 74
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!

If the system is not extensive enough then a special trip-odometer could be fitted to count the distance driven on the system.

What a marvelous and original way to promote cycling and physical exercise in the UK!
You can recognize people by their gait when on foot, and I wouldn't be surprised if you could recognize cyclists based on what they look like while pedaling. Cycling won't save you, it'll just make you easier to catch.

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.

Half the advantage of electric cars is efficiency (the other half being moving the pollution out of the city to a place where less people live). Can anyone comment on the theoretical or actual efficiency of this process? And is it simple induction, or does "Shaped Magnetic Field" mean more than activate a coil?

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

The electric wires are unsightly though, and require maintenance, and limit the height of vehicle that may operate on that stretch of road.

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.

Except that the average speed camera sections are set to catch people driving above 85MPH, so you have a lot of leeway there to "slip" over the speed limit.

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,

As for average speed limit cameras, how about just following the law?
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.
It's all to do with screwing the driver over, as usual, and using safety as a pathetic excuse.

I didn't drive on British motorways but I did in French motorways that are good quality and with a 130 km/h (about 80 mph) speed limit and yet I drive at... 70 mph.
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.

Yes, embedding cables in the roadway is not going to be viable for a variety of reasons and I don't need any pilot program to tell me that.

Inefficient in terms of what? Cost, energy, time? In terms of time cars are often twice or 2.5 times as time efficient as public transport for most people, even during peak commuting times. Just do some comparisons using Google Maps and you will get a good idea of the differences. Sure in dense metropolitan downtown areas, cars are going to be less time efficient beca

In the US, most suburban areas are dominated by houses surrounded by (potential) gardens. 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.
