00:00So, Hannah, you know what's special about this car?
00:02Besides being nice and cosy.
00:06Cosy is one word for it.
00:08What's happening on the background is that every time we're driving over this specific lane,
00:13we are wirelessly charging the vehicle while we're driving.
00:18Yes, it charges as you drive, with no wires or charge points.
00:26Show me.
00:27OK, so here, you see this?
00:29It's charging.
00:30OK, so it's charging. So, if I come off...
00:32And...
00:33Oh!
00:34Wait.
00:36It diminishes to zero.
00:37Yeah.
00:38Go back on.
00:38And if I go back on...
00:40Amazing! Look at that!
00:43So, what is the secret to those blue lines?
00:46Spill the beans, Gilad.
00:50Just look at those toys when we were kids and he has those little cars that went on the electrified road.
00:56Like Skeletrics kind of thing.
00:57Yeah.
00:57It's the same principle.
00:59OK, but those toy cars have got, like, the little wire brushes that hang down from underneath.
01:04If I turn this car upside down, will I see the same thing under here?
01:06No. What you will see is basically a receiver.
01:09The receiver is a 40-centimeter-wide electromagnetic coil linked to the car's battery.
01:19Another coil in the road transfers power to the car.
01:22This is the bit in the road.
01:23This is the bit in the road.
01:24This is the coil segment.
01:25It's super simple.
01:26It's basically rubber with copper in it.
01:29It's super simple.
01:30It's super simple.
01:30Buried 20 centimeters below the surface, the coil segments are linked together in a row.
01:36When high voltage electricity passes through them, it creates an invisible magnetic field.
01:43When the car's receiver passes through this field, it converts it back into electricity, charging the battery quicker than the vehicle uses it.
01:53It's super simple.
01:54The input.
01:55It's super simple.
01:56I won't.
01:57Why should I have a little bit more to it?
01:59I don't know.
02:00That's what I'm thinking about.
02:01It's like a clue.
02:02I can't understand.
