Looks like Warped Perception (the same guy who filmed the original "see-through" rotary engine) has added another rotary video. It's showing some cool and interesting rotary tech and I figure some of y'all might find this pretty neat.

Here's the link:
Based on the design I'm a little curious how well it would scale up - hollow crankshaft and all - but four horsepower out of that little thing is still pretty impressive regardless. Now I'm curious to see a two rotor version.

 

Pretty cool.

They flipped it around with the apex seals on the periphery.

 

Definitely a different design but very neat and interesting! Thank you for sharing!
