Now you're being silly, Morris. Have you taken leave of your senses? You didn't put much thought into that, did you?
The majority of the public will not tolerate atomic power, yet you suggest concentrating a far greater potential form of energy.
I don't see it passing the pub test.
Moderators, I strongly suggest Morris's post be deleted, before North Korea get wind of it.

Cobbadog, The air cleaner would only have to be good enough to filter out bunyips, Tasmanian tigers and black panthers.
V8Ian, Don't worry, all the hot air is already being generated. What else but the hot air from all centres of Government around the world would be causing the hole in the Ozone layer, as well as global warming?

Maybe the air cleaner mob are owned by cat , what colour are the inside of the air cleaner, if there green Detroit own them .....and if they are yellow cat own them , this guy tried to tell me that this engine was a cat , for a start it’s green and secondly it’s a two stroke , nice try mate , get to the back of the line ... mate.
