Nice try! It's a frickin' slot car! It's bound to work in Canada!!!

OK, like most of it but what prevents a short circuit in wet weather or an accidental human/animal zap?

It will be interesting to see just how well it stands up to a downpour - water and 750v DC don't get play very well together.
Another thing, how do they propose keeping the pickup pad on the tracks if the truck has to veer sideways from the straight line?

Would cost as much to retrofit old roads as to include in new ones. What happens if an animal - cat, dog, critter - runs across in front? A good choice, flattened or fried! And how many shorted-out sections before something runs out of stored power and grinds to a traffic-jamming halt?

OK for long haul routes maybe but useless in cities or rural.

Max and ivan4: It uses a process called "induced current" a method where current from the source naturally generates a magnetic field, which in turn is converted back to an electric current in the pick-up. Since the magnetic flux passes through insulation there is no exposed conductive material to short circuit. Same technology is currently used to charge electric toothbrushes, except scaled down significantly.
The article also states that the pick-up uses smart tracking to keep it in position. From the photos it looks as though it slides left-right.
I cant see the 1000's of kilometers of Australian outback roads having this installed, though. Especially considering most of the are still dirt!

They already have things like this that can only go where the tracks dictate.......
(and if you missed it: Trains)

Due to the track being made up of short segments that are only charged when a properly equipped vehicle is over or just ahead of it and moving at least at 60 km/h (37 mph) any animals that get fried have already been run over.
Pure water does not conduct electricity. The water in rain and snow is pretty pure. Precipitation on the track is not the problem problem that most people think. In places that do not get enough rain to clean the insulators on high-tension distribution lines they use a truck very similar to a fire truck to wash the insulators with pure water when the lines are live; nobody gets fried.
re; TheOne
The inductive system was mentioned only as a possible option that was being worked on.
re; Matthew Giles
Trains have to stay on the tracks the truck or other vehicle has to be able to get onto the highway and attain as speed of at least 60 km/h (37 mph) thus it has an engine or batteries and is capable of going places that the tracks do not go.

I can see this used for public transport. Maybe take off the speed limit and implement these tracks in bus stops. If the bus pulls in to take passengers it can load the batteries. Also You can put these tracks on large intersections where transport has to wait a long time.

The guys at Volvo obviously do not read Gizmag or Science Daily otherwise they would know that the concept they are proposing is dead.
