:03:19. > :03:24.These spy cars aren't being used for anything that exciting,
:03:25. > :03:29.But now many of them are being banned after
:03:30. > :03:37.The cars work by filming a car parked illegally and, without

:04:34. > :04:45.Many scientists say if we want to avoid dangerous climate change we
:04:46. > :04:48.need to cut down the carbon emissions we release into the air by
:04:49. > :04:52.a huge amount. There is no single solution, but there is one type of
:04:53. > :04:57.transport that releases lots and lots of carbon emissions, air
:04:58. > :05:02.travel. Scientists have to find an alternative way to power planes.
:05:03. > :05:07.There aren't many solutions yet, but this plane, made by a steeple in
:05:08. > :05:12.Eastern Europe, is one of the most eco-friendly in the world. This
:05:13. > :05:17.plane uses no fuel to fly. In fact it has batteries, which you charge,

:05:23. > :05:25.take off and stay in the air. It doesn't release harmful gases into

:05:41. > :05:46.battery for 100 passenger aeroplane would be way too big with current
:05:47. > :05:50.technology. Scientists will have to build a plane that can go from
:05:51. > :05:57.London to Edinburgh at similar speeds to today's planes, but with
:05:58. > :06:00.almost no carbon emissions. That's all from me. Newsround is back in
:06:01. > :06:01.the morning. See you
