Very interesting. It appears as if they have some working models. From what I can see of the web site they don't want the designs to be perceived
as another "wankle" or rotary engine. However, this is not the case, they have to deal with many of the same problems that the designers of the
wankle engine had. The saying goes, for every increase in complexity you have an increased possibility of failure.
Rotary engines have been available from Mazda for 30+ years, and they've been around for almost 50 years. Why aren't you driving one if they are so
good? The fuel economy on them really isn't that good. The design that you linked to does look like it may increase fuel economy for a rotary
engine, and would probably be better suited for gaseous fuel such as propane or hydrogen rather than a "wet" fuel like gasoline because of the
increased volume to surface area. This is also true of the old "wankle" rotary engine design.
I don't see this as being a dramatic breakthrough that we will be buying in cars within the next 10-20 years. Unless the benefits hugely outweigh
the drawbacks it won't happen. Will the auto manufacturers retool for it, where are you going to find an affordable mechanic to work on it when it
breaks down, and how long is it going to last as compared to what we already have? These are all questions that will have to have answers before it
can be marketed.
As a side note, Chrysler called the rotary a " filthy pig" because it consumed tons of fuel and created tons of pollutants. They have a lot of
misconceptions to get past if the engine is as good as they claim.
