QT Guess this has been on the board already but its the tech they have put into it.
Linde seem to have solved storing fuel @ -253C .

Its a big engine though 5 .3 litres.
Cant quite see how that would be fuel efficient.

Sometime in the early 80's a goal for the US Auto industry was set for an improved mileage engine by 1999.
Nothing was done except to improve performance of an engine.
When it came time to come up with the goods thsi Pres. scrapped the requirement.

Cars got bigger again SUV's appeared all seemingly wearing W stickers.
Meanwhile BMW have been at this for that same 15 years !

I dont particularly like the irony but .............
