Battery Powered Vehicles, The Future??

[Terry]

I'm astounded by the news that all internal combustion engined cars will be banned by 2040. 

I'm with Lawrence here - I'm sure that it is only the sale  of internal combustion engined vehicles that will be banned - although, presumably, if it is a blanket ban it will also affect vehicles modified to run on LPG.

How about an LPG fuelled steam car? They certainly exist - but not new ones! Use a condenser on the exhaust to recycle as much water as possible - which, I think, might have been done before.  Certainly the one I saw in action on Isle of Man only produced a wisp of steam.
