This may be old news from looking at their website, but these engines appear to be pretty trick stuff. It's definitely an interesting concept and cool technology.

Nice find, looks like one of the only practical replacements for the standard engine ive seen. Imagine how much work it was to come up with a completely new design for an engine and actually take it all the way to prototype.... thats pretty impressive.

Crazy Aussies. I wonder what the RPM's are going to be. Looks fairly small, so pretty high I assume.?

 

Its improved alot since I last saw that prototype webpage... They had one installed on a trike the last time I checked.

 

Look at this engine design.... pretty radical http://www.rotoblock.com/
