Looks like you soon need to add a new engine to the game ;)

There is a new engine technology under development in my country. That could well be our future engines. It is called CRE.

"CRE are initials for ”Centric Reciprocating Engine”, which is an internal combustion engine, where a pair of two rotors moves forth and back related to one another around a common center axis, – further rotating simultaneously around the very same axis, creating chambers performing the phases of suction, compression, expansion and discharge of the exhaust gases."

It is a very interesting technology with multiple uses. Can be used as pumps and compressors too.

Found this video which is in my language (norwegian). Where they show a model wich demonstrates the working principle.

There are actually a number of engine designs that could be added to the game. Some used in real cars, some dead projects many others future tech like what you linked.


Doyle Rotaries, Swing-Piston Engines, Turbines, Spherical Motors (http://auto.howstuffworks.com/huttlin-sp...engine.htm)
If you look up engine concepts on youtube, you can find a lot of odd ones, here is an example of a Doyle Rotary: https://www.youtube.com/watch?v=lJ1kxbtsBSU


There are many upon many. Would make good additions for mods I think.
