Nothing truly new under the sun. http://en.wikipedia.org/wiki/All_wheel_drive, link to Porsche's heavy mover.

Saw a picture and caption years ago where this design was tested for moving Austrian artilley in the alps. The tractor/cab unit incorporated the generator.

HERES ANOTHER SEPPO INIVATION THAT NEVER GOT OFF THE GROUND PLUS WATER POWERED ENGINES.In the 1960's I was keen on the magazine called'popular mechanics'[dont even know if it still exists].One very intriguing and innovating article of the time featured a picture of a housewife with one of those old school yet progressive 'reusable string bags' and in it was a miniature jet motor that weighed about 20kg. this little power plant could run a 60's yank tank for 140 miles on a pound of coal dust and in those days u could buy 2000pound [yankee short ton] for a buck [do the maths its magic].Now riddle me this.....If super heated steam passed over a catalyst[red hot carbon] produces hydrogen and o2 which instantly burns creating heat [power] and water vapour why havent we seen water powered engines anywhere?Anyone care to comment or make there mark?
